Measures of adult pain: Visual Analog Scale for Pain (VAS Pain), Numeric Rating Scale for Pain (NRS Pain), McGill Pain Questionnaire (MPQ), Short-Form McGill Pain Questionnaire (SF-MPQ), Chronic Pain Grade Scale (CPGS), Short Form-36 Bodily Pain Scale (SF-36 BPS), and Measure of Intermittent and Constant Osteoarthritis Pain (ICOAP)

Critical Appraisal of Clinical Trials Evaluating Physical Therapy Treatments for Temporomandibular Disorders: A Scoping Review

BACKGROUND

Physical therapy seems the most promising treatment for temporomandibular disorders (TMD), although their effectiveness is controversial in general, due to high heterogeneity regarding study designs, applied treatments and outcomes measures.

OBJECTIVES

The aim of this scoping review is to analyse the methodological characteristics of clinical trials evaluating physical therapy treatments in subjects with TMD.

METHODS

A systematic search was conducted in Medline/PubMed, SPORTDiscus, Scopus, Web of Science, SciELO, Cochrane, ScienceDirect and EMBASE databases on 31 October 2023. Clinical trials evaluating physical therapy interventions in patients older than 18 years with TMD, published in English or Spanish languages. Data regarding content reporting of study designs, sample characteristics, interventions and outcome measures was extracted. Descriptive summary statistics were reported.

RESULTS

The search retrieved 15 322 records, and 136 were included. There were 107 randomised clinical trials, 5 non-randomised controlled trials and 24 non-controlled trials. Most studies had moderate to high risk of bias, small sample sizes (median, 44 subjects) and short follow-up periods (1-3 months). The most common diagnostic criteria used was the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) (48.9%). The most reported experimental interventions were manual therapy (40.4%), exercise (30.2%) and electrotherapy modalities (27.2%), and the most common outcome measure domains were pain (83.8%), range of movement (61.8%), disability (45.6%) and mechanosensitivity (29.4%). There was poor content reporting of experimental interventions.

CONCLUSIONS

Current literature of clinical trials of physical therapy interventions for TMD has moderate to high risk of bias, poor content reporting, small sample size and short-term follow-ups which limit internal and external validity, as well as applicability into clinical practice.

Association Between Pain During Pregnancy and Postpartum Depressive Symptoms in Adolescent and Adult Women

ISSUE

Postpartum depressive symptoms may be more prevalent and/or severe in vulnerable populations.

BACKGROUND

Postpartum depression represents a serious mental health problem associated with maternal suffering. Despite the relevance and clinical implications of investigating pain during pregnancy and the association with postpartum depression, there is limited research on this topic.

AIM

We evaluated the association between pain during pregnancy and postpartum depression symptoms in adolescent and adult women.

METHODS

This study included 86 pregnant women (42 adolescents aged 13 to 18 years and 44 adults aged 23 to 28 years) from Trairi region, Northeastern Brazil. The evaluation of pain intensity and postpartum depression symptoms was conducted using the validated instruments of the Pelvic Pain Assessment Form and Edinburgh Postnatal Depression Scale (EPDS), respectively. Mann-Whitney and Kruskal-Wallis tests compared depressive symptoms in relation to pain status.

FINDINGS

Overall, pregnant women reporting moderate to intense pain presented more depressive symptoms, with emphasis to "deep pain with intercourse" (p = .09), "burning vaginal pain after sex" (p = .01), "pelvic pain lasting hours or days after intercourse" (p = .06), and "pain with urination" (p = .09). When stratified by age group, significant associations were found only for the adolescents.

DISCUSSION

Our results suggest that women reporting pain in different daily situations have higher EPDS scores.

CONCLUSION

Pain during pregnancy is associated with postpartum depression symptoms, mainly among adolescents. Adequate screening and pain management during pregnancy may improve women's quality of life.

Feasibility of a Community-Based Aquatic and Peer Support Intervention for People With Musculoskeletal Disorders Delivered via a Cross-Sector Partnership-A Service Evaluation

INTRODUCTION

Worldwide, the unmet rehabilitation needs of adults with musculoskeletal disorders are high. Aquatic exercise is clinically effective in managing musculoskeletal disorders, but access to rehabilitative services is limited.

OBJECTIVE

To determine the feasibility of a community-based aquatic exercise and peer support intervention for patients with musculoskeletal disorders delivered via a multisector partnership between an NHS physiotherapy service, a leisure operator and a social enterprise that creates personalised exercise programmes delivered through an application on a tablet computer. Cost-sharing was implemented after an initial complimentary session.

METHODS

A mixed method service evaluation was undertaken. Patient demographics, attendance, and patient-reported outcomes were summarised using descriptive statistics. Semi-structured interviews and an online survey were employed to explore patient acceptability of the intervention.

RESULTS

Thirty four patients accessed the intervention during the 6-month pilot. Over half were from minority ethnic groups and nearly two thirds were in the bottom three deciles relating to low income. Patients exercised in a group of up to eight, supported by NHS rehabilitation professionals and volunteers. Provision of post-session refreshments encouraged connectivity between patients. Weekly attendance at the programme was high. Patient-reported outcome measures showed favourable changes in pain intensity and function following the intervention. Qualitative data suggest that the intervention was acceptable to patients.

CONCLUSION

Implementation of a community-based aquatic exercise and peer support intervention for people with musculoskeletal disorders via a cross-sector partnership involving the NHS appears feasible and acceptable to patients. Further research is needed to assess the impact on musculoskeletal health and health inequalities.

Upper extremity neuromuscular function can distinguish between individuals with and without glenohumeral labral repair

The purpose of this study was to determine whether common measures of neuromuscular function could distinguish injury status indicated by group membership (glenohumeral labral repair, uninjured controls). 16 individuals with glenohumeral labral repair (24.1 ± 5.0 years, 36.7 ± 33.3 months after surgery) and 14 uninjured controls (23.8 ± 2.7 years) volunteered. We measured mass-normalized shoulder abduction and wrist flexion maximal voluntary isometric contraction torque (Nm/kg), motoneuron pool excitability of the flexor carpi radialis (Hoffmann reflex), corticospinal excitability of the upper trapezius, middle deltoid, and flexor carpi radialis (active motor threshold [%]) bilaterally. Receiver operator characteristic curve analyses were performed to determine if each outcome could distinguish injury status along with their outcome thresholds. Binary logistic regression was used to determine the accuracy of classification for each outcome. Our results suggest shoulder abduction torque symmetry (≤95.5 %) and corticospinal excitability for the upper trapezius (≥41.0 %) demonstrated excellent diagnostic utility. Shoulder abduction torque (≤0.71 Nm/kg) and motoneuron pool excitability (≤0.23) demonstrated acceptable diagnostic utility. Shoulder abduction torque symmetry alone was the strongest indicator, and classified injury status with 90.0 % accuracy (p < 0.01). Overall, symmetric shoulder abduction strength most accurately distinguished individuals' injury status, suggesting the utility of bilateral assessment in this population.

Impact of prior knee surgery on change in knee pain, quality of life, and walking speed following supervised education and exercise therapy: an analysis of 30,545 people with knee osteoarthritis

To investigate the impact of prior knee surgery on changes in outcomes following an 8-week supervised patient education and exercise therapy program in patients with knee osteoarthritis. Patients were classified according to knee surgery in the most affected knee joint (yes/no) prior to enrolment in the Good Life with osteoArthritis in Denmark (GLA:D®) program. Between-group differences in outcome changes from baseline to 3 months follow-up were evaluated using linear regression stratified by sex. Outcomes were knee pain intensity (VAS, 0-100 mm), joint related quality of life (Knee Injury and Osteoarthritis Outcome Score Quality of Life subscale score (KOOS QOL, 0-100)) and walking speed (40-m fast-paced walk test). To evaluate clinically relevant between-group differences, proportions of patients reaching a threshold of minimal important change in the surgery and non-surgery groups were compared. Among 30,545 patients, 27% (n, 8254) had prior surgery in the most affected knee. The prior surgery and the non-surgery group experienced improvements in all outcomes with minor between-group differences in change in pain intensity (males, 0.03 95% CI - 0.9 to 1.0; females, 1.3 95% CI 0.6 to 2.1); KOOS QOL (males, 0.3 95% CI - 0.4 to 0.9; females 0.02 95% CI - 0.5 to 0.5); and walking speed (males, 0.01 95% CI - 0.01 to 0.02; females 0.01 95% CI 0.003 to 0.02). The responder analysis showed no clinically relevant between-group differences in improvements. Previous knee surgery does not seem to modify the clinical outcome following exercise therapy and patient education in patients with knee osteoarthritis.

Challenges of Measuring Self-Reported Exposure to Occupational Biomechanical Risk Factors Amongst People with Low Literacy Engaged in Manual Labour: Findings from a Cross-Cultural Adaptation and Psychometric Investigation in an African Population with Chronic Low Back Pain

PURPOSE

Occupational biomechanical factors are implicated in the aetiology and progression of low back pain (LBP). This study cross-culturally adapted and psychometrically investigated the Occupational Risk Factor Questionnaire (ORFQ) in a low literate Nigerian Igbo population with chronic LBP.

METHODS

Forward and back translation of the original ORFQ by clinical and non-clinical translators was followed by an expert committee review. The adapted ORFQ was pre-tested amongst rural Nigerian adults with chronic LBP using cognitive think-aloud interviewing. Internal consistency (Cronbach's alpha) and test-retest reliability (unweighted and linear weighted k statistic for item-by-item agreement, and intra-class correlation coefficient-ICC) were investigated amongst 50 rural and urban Nigerian dwellers with chronic LBP. Spearman's correlation and regression analyses were conducted with the Igbo-ORFQ, and measures of disability [World Health Organisation Disability Assessment Schedule (WHODAS 2.0), Roland Morris Disability Questionnaire (RMDQ), Back performance scale (BPS)], pain intensity [Eleven-point box scale (BS-11)] and social support [Multidimensional Scale of Perceived Social Support (MSPSS)], to test construct validity with 200 rural Nigerian dwellers with chronic LBP.

RESULTS

Cross-cultural adaptation highlighted difficulty conceptualising and concretising exposure to biomechanical risk factors. Item-by-item agreement, internal consistency (α = 0.84) and intraclass correlation coefficient (ICC = 0.83) were good. Some unexpected direction of associations between the biomechanical components of the Igbo-ORFQ, and disability, pain intensity, and social support prohibits establishment of construct validity.

CONCLUSION

Prospective studies comparing the Igbo-ORFQ to other measures of exposure to occupational biomechanical risk factors are required to establish the construct validity of the Igbo-ORFQ.

Effect of different obturation techniques on treatment results in single-visit non-surgical endodontic retreatment: randomized controlled clinical study

BACKGROUND

Evaluating the effect of different obturation techniques on postoperative pain level and radiographic healing on non-surgical endodontic retreatment (NSER) applied in a single visit in teeth with a single root canal and apical periodontitis (AP).

MATERIALS AND METHODS

Sixty-three teeth from 50 systemically healthy patients (mean age 34.19 ± 9.75 years; 27 women, 23 men) were included in the study. Residual root canal filling materials were removed. All teeth were randomly divided into three groups according to the obturation technique: cold lateral compaction (CLC), continuous wave compaction (CWC), and thermoplasticized gutta-core (TGC). Pain status was evaluated using the Numerical Pain Rating Scale (NRS) in all cases. Periapical index (PAI) scores were recorded in preoperative and postoperative 6-month on the periapical radiographs. Data were analyzed as statistically (IBM, Armonk, NY, USA). The significance level was determined as p < 0.05.

RESULTS

It was found that more postoperative pain occurred in the 3rd-hour interval after CLC and CWC compared to the 7th-day interval (p < 0.05). There was no difference in postoperative pain between obturation techniques in all evaluated time intervals (p > 0.05). There was no difference in the PAI scores recorded at six months between obturation techniques for all periods (p > 0.05). Similar radiographic improvement was observed in all obturation techniques at 6-months (p > 0.05).

CONCLUSION

CLC, CWC, and TGC root canal obturation techniques were found to have similar efficacy after NSER in a single visit in teeth with AP at six months.

Validity, reliability, and sensitivity to change of the Arabic version of the Migraine-Specific Quality-of-Life Questionnaire after prophylactic treatment

BACKGROUND

The Migraine-Specific Quality-of-Life Questionnaire version 2.1 (MSQ 2.1) is one of the most frequently used tools in assessing the impact of migraine in clinical practice and in migraine research. This work aimed to examine the reliability and validity of the Arabic version of the MSQ 2.1 in Arabic-speaking patients with migraine and to assess its ability to detect subtle changes in quality of life after receiving prophylactic migraine medications.

METHODS

This multicenter prospective observational study was conducted with 140 patients experiencing migraine and indicated for prophylactic medications. Headache assessment was done at baseline and 3 months after receiving prophylactic medications using the Arabic version of MSQ 2.1, Headache Impact Test (HIT-6), and visual analog scale (VAS). The MSQ 2.1 was repeated 1 week after the first visit to a group of patients (n = 70) to assess test-retest reliability.

RESULTS

Cronbach's alpha for the MSQ 2.1 was 0.973, indicating excellent internal consistency. The intraclass correlation coefficient (average measure) was 0.99, indicating excellent test-retest reliability. There were statistically significant correlations between the MSQ 2.1 total score and monthly migraine days, VAS, and HIT-6 scores before and 3 months after prophylactic medications. The receiver operating characteristic curve revealed that an increase of 8.5 in the total score of the MSQ 2.1 represents the minimally important change that means significant improvement (area under the curve = 0.785, sensitivity = 0.861, specificity = 0.656, p < 0.001).

CONCLUSION

The Arabic version of the MSQ 2.1 is a valid, reliable, and sensitive tool that can precisely assess the impact of migraine on quality of life.

Analysis of Dry Needling Combined with an Exercise Program in the Treatment of Knee Osteoarthritis: A Randomized Clinical Trial

Background: Therapeutic exercise is recommended for people with knee osteoarthritis (OA), although it could be complemented with other treatments such as dry needling (DN). The purpose of this study was to evaluate and compare the resulting data on pain, functionality, strength and range of motion in subjects with knee osteoarthritis after being treated with a specific therapeutic physical exercise program alone or in combination with the DN technique in the popliteus muscle. Methods: A total of 33 participants were randomly assigned to two groups: the dry needling plus therapeutic physical exercise group (n = 15) and the therapeutic physical exercise alone group (n = 18). Both groups received the same exercise protocol, and the dry-needling group conducted three sessions of this technique over 3 weeks. Results: Variables such as pain, functionality, neuropathic pain, stiffness, strength, range of motion, pain catastrophizing and kinesiophobia were evaluated before and after the intervention, as well as at a follow-up 3 months after the intervention. Significant differences were observed between the two groups in pain intensity, stiffness, functionality, pain catastrophizing and kinesiophobia (p < 0.001). Conclusions: The combination of dry needling targeting the popliteus muscle and therapeutic physical exercise showed better results in terms of pain, functionality and strength compared to therapeutic physical exercise alone, especially after the intervention.

Telerehabilitation using a 2-D planar arm rehabilitation robot for hemiparetic stroke: a feasibility study of clinic-to-home exergaming therapy

BACKGROUND

We evaluated the feasibility, safety, and efficacy of a 2D-planar robot for minimally supervised home-based upper-limb therapy for post-stroke hemiparesis.

METHODS

The H-Man, end effector robot, combined with web-based software application for remote tele-monitoring were evaluated at homes of participants. Inclusion criteria were: strokes > 28 days, Fugl-Meyer Motor Assessment (FMA) > 10-60/66, presence of a carer and absence of medical contraindications. Participants performed self-directed, minimally supervised robotics-assisted therapy (RAT) at home for 30 consecutive days, after 2 therapist-supervised clinic on-boarding sessions. Web-based compliance measures were: accessed sessions of > 20 min/day, training minutes/day and active training hours/30 days. Clinical outcomes at weeks 0, 5 (post-training), 12 and 24 (follow-up) consisted of FMA, Action Research Arm Test (ARAT) and WHO-Stroke Specific Quality of Life (SSQOL). To estimate immediate economic benefits of the home-based robotic therapy, we performed cost-effectiveness analysis (CEA), followed by budget impact analysis (BIA).

RESULTS

Altogether, all 12 participants completed Home-RAT without adverse events; 9 (75.0%) were males, mean (SD) age, 59.4 years (9.5), median (IQR) stroke duration 38.6 weeks (25.4, 79.6) baseline FMA (0-66) 42.1 ± 13.2, ARAT (0-57) 25.4 ± 19.5, SSQOL (0-245) 185.3 ± 32.8. At week 5 follow-up, mean (SD) accessed days were 26.3 days ± 6.4, active training hours of 35.3 h ± 14.7/30 days, or ~ 6 days/week and 77 training minutes ± 20.9/day were observed. Significant gains were observed from baseline across time; ΔFMA 2.4 at week 5 (FMA 44.5, CI 95% 39.7-49.3, p < 0.05) and ΔFMA 3.7 at week 24 (FMA 45.8, CI 95% 40.5-51, p < 0.05); ΔARAT 2.6 at week 5 (ARAT 28.0, CI 95% 19.3-36.7, p < 0.05), and ΔARAT 4.8 at week 24 (ARAT 30.2, CI 95% 21.2-39.1, p < 0.05). At week 5 follow-up, 91% of participants rated their overall experience as satisfied or very satisfied. Incremental CEA observed savings of -S$144/per cure over 24 weeks, BIA-potentially 12% impact reduction over five years.

CONCLUSIONS

This study demonstrates the feasibility, acceptability, safety, clinical efficacy, and cost-effectiveness of a home-based, web-enabled telemonitored carer-supervised robotics-aided therapy.

The relationship between sleep and menstrual problems in early adolescent girls

Introduction

Adolescence is marked by hormonal, physical, neural, and behavioral changes, including in sleep patterns and, in females, the onset of menarche. Menstrual problems, such as painful menses, are common and contribute to school absences, and could indicate gynecological conditions impacting reproductive health. While studies in adults have shown associations between sleep disturbances and menstrual problems, this relationship is less understood in adolescents. Our study explores the association between sleep, menstrual problems, and menarche in a diverse sample of early adolescent girls in the U.S.

Methods

We used linear mixed-effect models to analyze associations between sleep behavior (self- and caregiver-reported) and menstrual problems (self-reported cycle irregularity, premenstrual symptom and menstrual pain severity and their impact on daily life) and menstrual characteristics (menstrual flow) in 3,037 post-menarcheal adolescent girls (Mean age:13.03 years) from the ABCD Study®. Covariates included years since menarche, race, ethnicity, parental education, and body mass index. We also used longitudinal data to explore changes in sleep behavior as a function of menarche.

Results

Of the sample, 26.2% reported moderate-severe premenstrual symptoms and 20.8% reported moderate-severe menstrual pain. 23.3% reported irregular menstrual cycles, 15.9% reported heavy menstrual flow. Shorter sleep duration was associated with greater menstrual pain intensity (β =-0.19) and impact on daily activities (β = -0.15), irregular cycles (β = -0.17), and severe premenstrual symptoms (β = -0.04). Higher sleep disturbance scores correlated with greater menstrual pain (β = 0.18) and premenstrual symptom severity (β = 0.03). Later wake-up times were linked to greater menstrual pain intensity (β = 0.14). Shorter time since menarche was associated with lower menstrual flow (β = 0.07) and pain intensity (β = 0.51) and less severe premenstrual symptoms (β = 0.07). Being post-menarche was associated with later bedtimes and shorter sleep duration.

Conclusion

Findings of links between sleep behavior and menstrual problems in early adolescence underscore the importance of addressing sleep and menstrual issues in healthcare screenings and educational initiatives for adolescents. Future research should focus on longitudinal and intervention studies to clarify these relationships.

Walking as a Mediator Between Strength and Health-Related Quality of Life in Multiple Sclerosis

Background and Purpose: Lower limb (LL) weakness and gait impairment are prevalent among persons with multiple sclerosis (PwMS) and can impede functional independence and impact health-related quality of life (HR-QoL). The purpose of this study was to examine the mediation effect of walking speed and perceived walking ability on the relationship between LL weakness and HR-QoL in ambulatory PwMS.

METHODS

Participants (n = 175) were PwMS in this secondary analysis of a cross-sectional study. Demographics, pain (visual analog scale), fatigue (5-item Modified Fatigue Impact Scale), LL strength (hip extensors [HE] and flexors [HF], knee extensors [KE] and flexors [KF], and ankle plantarflexors [APF] and dorsiflexors [ADF]), Timed 25-Foot Walk, 12-item MS Walking Scale, and HR-QoL (MS Impact Scale-Physical [MSIS-29-Phys] and Psychological [MSIS-29-Psych]) were collected. Bivariate and mediation analyses using Hayes' PROCESS were performed to determine if LL strength had an indirect effect through walking speed or perceived walking ability on physical and psychological HR-QoL while controlling for fatigue and pain.

RESULTS

There were significant ( P < 0.01) correlations for all strength measures with the MSIS-29-Phys and for HF, KE, KF, and APF with the MSIS-29-Psych. In the mediation analyses, LL strength indirectly influenced PwMS' MSIS-29-Phys through walking speed and perceived walking ability. There was only partial mediation between HE, HF, KF, ADF, and MSIS-29-Phy when walking speed was in the model. LL strength did not influence MSIS-29-Psych.

DISCUSSION AND CONCLUSIONS

LL strength impacts physical HR-QoL through walking but does not indirectly affect PwMS' perceived psychological HR-QoL. These findings may prompt physical therapists to create individualized care plans that address LL weakness and walking impairments with the goal of promoting optimal outcomes and improving HR-QoL.

Calcaneal lengthening osteotomy using ipsilateral fibular graft in the treatment of flexible flatfoot deformity: preliminary results

PURPOSE

Flexible flatfoot deformity is quite common among adolescents. This study aimed to report the preliminary results of calcaneal lengthening osteotomy using a fibular bone graft.

METHODS

This single-center, retrospective study included 28 patients (28 feet) with symptomatic flexible flatfoot deformity. The deformity was corrected with calcaneal lengthening osteotomy using an ipsilateral fibular graft. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle hindfoot score at the final follow-up was selected as the primary outcome measure. Radiographic outcomes included the anteroposterior talo-first metatarsal (AP talo-MT1) angle, the lateral talo-first metatarsal (LAT talo-MT1) angle, the lateral calcaneal pitch (LCP), and the Goldberg scoring system (GSS) for fibular graft incorporation. The visual analogue scale (VAS) was used to assess pain over the ipsilateral fibula donor site.

RESULTS

The AOFAS ankle hindfoot score improved from a mean of 53.7 ± 22.4 to a mean of 81.1 ± 19.8, the AP talo-MT1 angle improved from a mean of 24.1° ± 15.6 to a mean of 12.9° ± 7.3, the LAT talo-MT1 angle improved from a mean of 22.3° ± 3.2 to a mean of 7.9° ± 2.3, and the LCP improved from a mean of 10.1° ± 7 to a mean of 24.4° ± 9.1. The GSS was seven points in all patients, which indicated complete radiographic union with an excellent reorganization of the fibular bone graft. The VAS for pain over the ipsilateral fibula donor site was zero at the final follow-up.

CONCLUSION

The fibular bone autograft achieved excellent incorporation when used in calcaneal lengthening osteotomy with good improvement in the clinical and radiographic outcomes in patients with symptomatic flexible flatfoot deformity.

Acute ingestion of acetaminophen improves cognitive and repeated high intensity short-term maximal performance in well-trained female athletes: a randomized placebo-controlled trial

This study examined the effect of acute acetaminophen (ACTP) ingestion on physical performance during the 5 m shuttle run test (5mSRT), attention, mood states, and the perception of perceived exertion (RPE), pain (PP), recovery (PRS), and delayed onset of muscle soreness (DOMS) in well-trained female athletes. In a randomized, placebo-controlled, double-blind, crossover trial, fifteen well-trained female athletes (age 21 ± 2 years, height 165 ± 6 cm, body mass 62 ± 5 kg) swallowed either 1.5 g of ACTP or 1.5 g of placebo. The profile of mood states (POMS) and digit cancellation (DCT) were assessed 45 min postingestion, and 5mSRT was performed 60 min postingestion. The RPE and PP were determined immediately after each 30-s repetition of the 5mSRT, and the PRS and DOMS were recorded at 5 min and 24 h post-5mSRT. For the 5mSRT, ACTP ingestion improved the greatest distance (+ 10.88%, p < 0.001), total distance (+ 11.33%, p = 0.0007) and fatigue index (+ 21.43%, p = 0.0003) compared to PLA. Likewise, the DCT score was better on the ACTP (p = 0.0007) than on the PLA. RPE, PP, PRS, and DOMS scores were improved after ACTP ingestion (p < 0.01 for all comparisons) compared to PLA. POMS scores were enhanced with ACTP ingestion compared to PLA (p < 0.01). In conclusion, this study indicates that acute acetaminophen ingestion can improve repeated high intensity short-term maximal performance, attention, mood states, and perceptions of exertion, pain, recovery, and muscle soreness in well-trained female athletes, suggesting potential benefits for their overall athletic performance and mood state.

Oral nonsteroidal anti-inflammatory drugs as treatment of joint and muscle pain in temporomandibular disorders: A systematic review

OBJECTIVE

To evaluate pain control in patients with joint and muscle pain in temporomandibular disorder (TMD) diagnosis treated with oral non-steroidal anti-inflammatory drugs (NSAIDs).

METHODS

The systematic research was conducted via Pubmed, Scopus, Web of Science, Google Scholar, and Cochrane databases.

RESULTS

Four full-text randomized-controlled trials (RCTs) were considered eligible. This systematic review included 164 patients whose VAS scores were assessed before and after therapy. In the selected studies, a strong heterogeneity in the diagnosis and in the use of different types and prescriptions of NSAIDs was highlighted. These limitations had to be considered to understand whether a clinical recommendation could be made. Eventually, all patients treated with NSAIDs showed an improvement in pain.

CONCLUSION

The use of oral NSAIDs as the first approach to control joint and muscle pain is sustained by the current scientific literature, but further investigations on this topic are still needed.

An Integrative Approach for Endometriosis-Related Pain

BACKGROUND

Pain is a common, severe symptom related to endometriosis. Despite this prominent feature, there is limited literature regarding its description and use of integrative treatment methods.

OBJECTIVE

We aimed to describe endometriosis-related pain characteristics, severity, and association with an integrative approach encompassing pharmacological and non-pharmacological methods.

METHODS

A cross-sectional descriptive correlational study was conducted using convenience sampling of adult women with endometriosis-related pain. Three questionnaires were utilized: a demographic and general health questionnaire, a visual analog pain scale (VAS), and the short-form McGill pain questionnaire (SF-MPQ).

RESULTS

Participants included 93 women with a mean general pain level of 6.2/10 (SD = 2.7) on the VAS. The total mean pain score on the SF-MPQ was 26.25/45 (SD = 10.1). Sixty-four women (68.8%) reported experiencing pain at the time of completion of the questionnaire (mean: 1.6/4, SD = 1.3). All participants utilized analgesia; those who used opioids reported a higher overall mean pain score of 2.3 (SD = 1.3) than patients who did not use opioids reported a mean of 1.4 (SD = 1.2; z = 9.59; P < .001). Present pain intensity was significantly higher for women using opioids than those not using opioids. In all, 77 women (82.8%) used integrative methods to alleviate the pain symptoms. Women who utilized nutritional therapy as part of the non-pharmacological method experienced lower mean (SD) overall pain (4.4 [2.5]) compared with patients who did not utilize nutritional therapy (6.75 [2.5]; P < .01).

CONCLUSIONS

More studies are needed to find evidence-based treatment options for women for integrative pain relief for endometriosis-related pain.

Relationship between preoperative and discharge evaluations in patients receiving around-the-knee osteotomy

[Purpose] This study aimed to determine the relationship between preoperative and discharge assessments in patients undergoing around-the-knee osteotomy. [Participants and Methods] We enrolled patients admitted to our hospital who underwent around-the-knee osteotomy. We measured knee joint range of motion, pain numeric rating scale, pain catastrophizing scale, hospital anxiety and depression scale, and 10-m walk time were measured preoperatively and before discharge. Pre-post comparisons and correlation testing were performed. [Results] A total of 18 patients were analyzed. Resting and exercise pain numeric rating scale, knee flexion and extension range of motion, and pain catastrophizing scale were significantly better during discharge. A significant correlation was observed between the preoperative pain catastrophizing scale total score and 10-m walking time, knee flexion and extension range of motion, pain catastrophizing scale total score, and hospital anxiety and depression scale-depression subscale preoperatively. [Conclusion] Appropriate postoperative rehabilitation after around-the-knee osteotomy improved physical function and cognitive/psychological evaluation at discharge. The correlation between the preoperative pain catastrophizing scale total score and 10-m walking time at discharge suggests that the prolonged walking pain that occurred preoperatively may have affected the cognitive and psychological evaluation of pain.

More neck pain, less spinal mobility, altered sitting posture: Sagittal spinal alignment and mobility in women with chronic neck pain

BACKGROUND

Increasing evidence suggests that people with chronic neck pain (CNP) may display altered biomechanics beyond the cervical spine. However, whether spinal alignment and mobility are associated with neck pain is not clarified.

OBJECTIVES

To investigate whether there is a significant association between neck pain intensity and sagittal spinal alignment and mobility in people with CNP, and to examine whether sagittal spinal alignment and mobility differ according to pain intensity.

DESIGN

A cross-sectional study.

METHOD

Forty-four women with CNP were included. The neck pain intensity at rest and during neck movements was assessed with the visual analogue scale (VAS). A skin-surface measurement device was used to assess sagittal alignment and mobility while sitting and standing. Linear regression analysis was used to assess associations. Participants were divided into two groups according to the pain intensity as group with mild pain (VAS≤4.4 cm) and group with moderate to severe pain (VAS>4.4 cm) and compared using the analysis of covariance.

RESULTS

Greater resting pain was associated with a more forward trunk during sitting (Beta = 0.433, p < 0.05). Greater pain during neck movements was associated with increased lumbar lordosis during sitting (Beta = -0.376, p < 0.05). Classified by pain intensity at rest, trunk mobility while sitting was lower and forward trunk inclination and sacral kyphosis while sitting were higher in those with moderate/severe pain (η2p = 0.093-0.119, p < 0.05). By pain intensity during neck movements, women with moderate/severe pain exhibited lower sacral mobility while sitting (η2p = 0.129, p < 0.05).

CONCLUSIONS

Addressing the entire spine in the assessment and management of CNP may help reduce pain.

Mindfulness in the Clinic Waiting Room May Decrease Pain: Results from Three Pilot Randomized Controlled Trials

Introduction: Mindfulness interventions can improve a broad range of patient outcomes, but traditional mindfulness-based interventions are time and resource intensive. Emerging evidence indicates brief, single-session mindfulness interventions can also improve patient outcomes, and brief mindfulness interventions can be embedded into medical care pathways with minimal disruption. However, the direct impact of a brief mindfulness intervention on patients' pain while waiting in the clinic waiting room remains unexamined. Objective: A series of three, pilot, randomized controlled trials (RCTs) were conducted to examine the impact of a brief, audio-recorded, mindfulness intervention on patients' pain in the clinic waiting room. Method: Study 1 examined an 8-min mindfulness recording delivered before a provider visit; Study 2 examined a 5-min mindfulness recording after a provider visit; and Study 3 examined a 4-min mindfulness recording before a provider visit. Time- and attention-matched control conditions were used in each study. Studies 1 and 2 were conducted in an academic cancer hospital. Study 3 was conducted at a walk-in orthopedic clinic. Pain intensity was measured in each of the three studies. Anxiety and depression symptoms were measured in Studies 2 and 3. Pain unpleasantness was measured in Study 3. Results: A brief (i.e., 4- to 8-min), audio-recorded mindfulness intervention decreased patients' pain intensity in the clinic waiting room, whether delivered before (Study 1 Cohen's d=1.01, Study 3 Cohen's d=0.39) or after (Study 2 Cohen's d=0.89) a provider visit. Mindfulness had a significant effect on anxiety symptoms in both studies in which it was measured. No effect on depression symptoms was observed. Conclusions: Results from these three pilot RCTs indicate brief, audio-recorded, mindfulness interventions may be capable of quickly decreasing clinical symptoms. As such, embedding brief, audio-recorded, mindfulness interventions in clinic waiting rooms may have the potential to improve patient outcomes. The continued investigation of this intervention approach is needed. Clinical Trial Registrations: NCT04477278 and NCT06099964.

Muscle characteristics of lower limb in association with physical activity in candidates of total knee arthroplasty with knee osteoarthritis

BACKGROUND & AIMS

This study aimed to clarify the association between physical activity (PA) and physical functions, including both muscle quantity and quality of ankle plantar flexor muscles in patients with knee osteoarthritis (OA).

METHODS

A retrospective cohort study was conducted with ninety-two patients with knee OA. PA, leg muscle cross-sectional area (CSA), knee strength, passive knee angle, and knee pain of the affected side were assessed. PA was assessed by the 2011 Knee Society scoring system. CSA of the quadriceps and ankle plantar flexor muscles on the affected side was measured using a computed tomography image. Based on muscle attenuation assessed with Hounsfield units (HU), the muscle quality of targeted muscle was divided into 4 groups as follows: fat tissue (-190 to -30 HU), very low-density muscle (-29 to -1 HU), low-density muscle (0 to 34 HU), and normal-density muscle (NDM, 35 to 100 HU). The CSA was obtained for each of the 4 groups. Univariate and multivariate linear regression analyses were performed to determine the factors associated with PA.

RESULTS

The regression analysis revealed that higher PA was independently associated with the NDM CSA of ankle plantar flexor (β = 0.51), higher knee extension strength (β = 0.28), and milder knee pain (β = -0.29) after adjustment with age, sex, height, weight, and body mass index.

CONCLUSION

The present study suggested that NDM CSA of ankle plantar flexor in addition to knee function is one of the factors determining the PA in patients with knee OA.

Predictors of dropping out from a home tele-exercise programme: A cohort study derived from a randomised controlled trial

Background

Online home exercises represent opportunities to increase physical activity levels. However, high dropout rates are commonly reported in such programmes. This study aimed to investigate the predictors of dropping out from an online home exercise programme.

Methods

A total of 760 individuals from nine countries participated in this 8-week prospective cohort study derived from a randomised controlled trial. The participants were randomised into "4-week live-streamed exercise ->4-week recorded exercise" or "4-week no intervention ->4-week recorded exercise" group. Repeated measurements using weekly questionnaires were performed. Pain intensity, disability, mental well-being score, exercise motivation, sleep quality, impulsiveness/anxiety, and physical activity level were analysed.

Results

A total of 53.8% (95% confidence interval [CI] 50.3%-57.3%) participants dropped out from the programme. The identified predictors of dropping out from the programme were: well-being (odds ratio [OR] 0.94, 95% CI 0.91-0.97) and disability (OR 1.02, 95% CI 1.002-1.04) at baseline considering the first 4 weeks; age (0.98; 95% CI 0.96-1.00) and baseline well-being (0.93; 95% CI 0.89-0.97) considering the entire follow-up (8 weeks); exercise motivation (0.92; 95% CI 0.87 to 0.97) and general impulsiveness/anxiety (1.04; 95% CI 1.01-1.07) repeated measured over time.

Conclusion

About half of the participants dropped out from the online home exercise programme. Higher baseline scores in mental well-being and age predicted a reduction in dropping out. Higher baseline disability predicted an increase in dropping out. During the follow-up, higher exercise motivation was associated with a reduction in dropping out, and higher impulsiveness and anxiety were associated with an increase in dropping out.

A study to explore the role of a low threshold, fitness focussed physical rehabilitation intervention with protein supplementation to target physical function and frailty in people with problematic substance use and homelessness: protocol for a single-arm pre-post intervention study

Background

People who are homeless are more likely to experience poor mental health and addiction as well as suffering from non-communicable diseases. There is evidence of frailty and accelerated physical ageing among people experiencing homelessness. Appropriate physical rehabilitation and nutritional supplementation strategies can stabilise or reverse frailty and general physical decline, but it is not known how this type of intervention would work in practice in this population.

Aim

To evaluate the feasibility and pre-post intervention impact of a low threshold physical rehabilitation intervention with protein supplementation to target physical functioning and frailty in people with problematic substance use who are experiencing homelessness.

Methods

The intervention will consist of a 12-week low threshold rehabilitation programme with protein supplementation. Participants will be service users of the Ballyfermot Advance Project, a day services centre for people with addiction issues and experiencing homelessness. Primary outcomes will be feasibility including numbers recruited, retention of participants and adherence to the exercise intervention and protein supplement. Any adverse events will be recorded. Secondary outcomes will be strength and muscular mass, physical performance and lower extremity physical function, pain, frailty and nutritional status.

Discussion

An immediate impact may be simply a distraction from difficult circumstances and potentially an improvement of physical health of participants, which can be a conduit for the emergence of other positive behaviours and recovery. Longer term, this study will generate preliminary data on which to inform the design of a definitive randomised controlled trial of physical rehabilitation and protein supplementation, if indicated.

Ethics and dissemination

Ethical approval was granted by the Faculty of Health Sciences Research Ethics Committee in TCD. Study findings will be disseminated through publication into an international peer-reviewed journal and presented at national and international conferences.

The acute cross-education effect of foam rolling on the thigh muscles in patients after total knee arthroplasty

INTRODUCTION

In the early postoperative period after total knee arthroplasty (TKA), joint range of motion (ROM) limitation and increased stiffness due to pain are commonly observed. Previous studies have reported that a single bout of foam rolling (FR) can acutely increase ROM and pain threshold on the contralateral (non-intervention) side in healthy participants. In this study, we aimed to expand this knowledge for TKA rehabilitation and investigated the acute effects of FR intervention on the non-operative side on ROM, stiffness, and pain of the operative side in postoperative patients within the first week after TKA.

MATERIALS AND METHODS

The study employed a randomized crossover design: 20 patients (mean age 75.0 ± 7.8 years) in the first postoperative week after TKA were divided alternately into Roll_Break and Break_Roll groups in the order of prescription. In the Roll_Break group, after the initial evaluation, a 180-s (60-s × three sets) FR intervention using a roller massager by a physiotherapist for the knee extensors was performed on the contralateral side (non-operative side), followed by the measurement. Afterwards, after 180-s of supine at rest, the measurement was performed again (i.e., control phase). In the Break_Roll group, after the initial evaluation, each patient was placed in a seated resting position for 180-s, and then another measurement was performed (i.e., control phase). After this, the FR intervention was performed for 180-s, and then the measurement was performed again. The intensity of the FR intervention was set to the maximum intensity that did not cause pain. We measured pain using the visual analogue scale at rest and during the knee joint ROM measurements, knee joint active movement ROM, knee joint passive ROM, and stiffness during the knee joint active movement.

RESULTS

All outcome variables showed significant improvements after the FR intervention (intervention phase) when compared pre- to post-intervention, and significantly favourable effects were found compared to the control condition.

CONCLUSION

The results showed significant improvements in ROM, pain, and stiffness of the operative side after the FR intervention on the non-operative side. For future therapy approaches for TKA patients, FR treatment of the non-operative side should be employed in the first weeks after surgery.

Decompression Illness After Technical Diving Session in Mediterranean Sea: Oxidative Stress, Inflammation, and HBO Therapy

SCUBA diving poses risks due to pressure changes during descent (compression) and ascent (decompression). Decompression sickness (DCS) occurs due to gas bubble formation as the pressure decreases, causing joint pain, numbness, dizziness, or even paralysis and death. Immediate treatment involves 100% oxygen to help eliminate inert gases and hyperbaric oxygen therapy (HBOT), which is essential to reduce gas emboli formation and inflammation, thus improving symptoms. We evaluated oxy-inflammation biomarkers in the saliva and urine of nine subjects pre- and post-technical dive on the Haven wreck (GE, Italy). A case of DCS occurred during the dive. The injured diver was treated immediately with O2 and transported to the hyperbaric center of "ASST Ospedale Ca Granda" in Milan. He was treated following the U.S. Navy Treatment Table 5 at 2.8 ATA and the day after with Table 15 at 2.4 ATA. Venous blood and urine samples were collected before and after each HBO treatment. Our study shows that dive increased oxy-inflammation biomarkers (ROS +126%; lipid peroxidation +23%; interleukins-6 +81%, -1β +19%, and TNFα +84%) and nitric oxide metabolites levels (+36%). HBOT after a DCS episode reduced oxidative stress, lowering the very high marker of lipid peroxidation (8-iso-PGF2α), and inhibited inflammatory interleukins. Overall, HBOT improved physiological responses in the diver affected by DCS.

Clinical Efficacy and Safety of Ultrasound-Guided Injection with Low-Molecular-Weight Peptides from Hydrolyzed Collagen in Patients with Partial Supraspinatus Tendon Tears: A Pilot Study

BACKGROUND

This study evaluates the clinical efficacy and safety of two ultrasound (US)-guided injections of a 5 mg/1 mL low-molecular-weight peptide (LWP) solution derived from hydrolyzed bovine collagen in patients with supraspinatus partial tendon tears.

METHODS

A total of 21 patients with symptomatic partial tears of the supraspinatus tendon, detected by US, were consecutively enrolled and received one injection at a baseline visit (T0) and one after two weeks (T1). The primary outcome measure was the visual analogue scale (VAS) for pain. Secondary outcomes were the shoulder pain and disability index (SPADI) total score and the safety of LWP injections. Patients were examined at baseline (T0), at a week 2 follow-up visit (T1), and at a week 12 follow-up visit (T2).

RESULTS

A statistically significant improvement was found for both VAS pain and SPADI total scores, between T0 and T2 visits. US-guided injections were well tolerated and, apart from one patient with a progression of a tendon tear, no adverse events were recorded.

CONCLUSIONS

Intratendinous tear US-guided injection therapy with an LWP solution was found to be safe and effective in improving both pain and shoulder function at a 12-week follow-up visit. The present pilot study should be considered the first step justifying a larger confirmatory investigation.

Assessing the Association of Pain Intensity Scales on Quality of Life in Elderly Patients with Chronic Pain: A Nursing Approach

BACKGROUND

Chronic pain is prevalent among the elderly and significantly affects their quality of life (QoL). Pain intensity scales are crucial tools in evaluating the severity of pain and tailoring management strategies. This study investigates the relationship between various pain intensity scales and QoL among elderly patients with chronic pain, highlighting the implications for nursing practice.

METHODS

A cross-sectional study was conducted with 150 elderly patients (aged 65 and above) in Riyadh, Saudi Arabia. Participants were assessed using the Numeric Rating Scale (NRS), Visual Analog Scale (VAS), and McGill Pain Questionnaire (MPQ) alongside the 36-Item Short-Form Health Survey (SF-36) to evaluate QoL. Data analysis involved Pearson correlation and multiple regression to explore the association of pain intensity on QoL.

RESULTS

All pain scales showed significant negative correlations with QoL. The MPQ exhibited a significant association, suggesting its comprehensive nature captures the multidimensional association of pain more effectively. Regression analysis identified pain intensity, age, and duration of chronic pain as significant predictors of reduced QoL.

CONCLUSIONS

The findings emphasize the importance of selecting appropriate pain assessment tools that reflect the complex nature of pain in elderly patients. Implementing comprehensive pain assessments like the MPQ can enhance individualized care strategies and potentially improve the QoL in this population. This study underscores the role of nurses in optimizing pain management approaches tailored to the elderly.

EXPLORING THE FEASIBILITY OF PLATELET-RICH PLASMA INJECTIONS FOR INTERVERTEBRAL DISCOPATHY: A PILOT STUDY

Objective

This longitudinal pilot study aimed to evaluate the feasibility, safety and potential benefits of Platelet-Rich Plasma injections into the lumbar intervertebral discs in patients with low back pain and degenerative intervertebral monodiscopathy, assessing potential efficacy on disability.

Design

Longitudinal pilot study.

Methods

Six participants with chronic low back pain and lumbar degenerative intervertebral disc (monodiscopathy) disease underwent 1 Platelet-Rich Plasma injection, with a 1-year follow-up. Platelet-Rich Plasma injections were administered into the lumbar intervertebral disc, and outcomes were measured using the Roland Morris Disability Questionnaire, numeric rating scale for pain, Tampa scale for kinesiophobia and lumbar flexion range. Magnetic resonance imaging analysis assessed disc changes.

Results

No adverse events were reported. At the end of the 1-year follow-up, half of the patients showed significant improvements in disability scores at 1 year, while 3 of the 6 patients had no change. Magnetic resonance imaging revealed no significant disc changes.

Conclusion

Platelet-Rich Plasma injections show promise for some patients with low back pain and degenerative intervertebral discopathy patients. However, caution is warranted due to study limitations, including small sample size and lack of a control group. Further research is needed to define Platelet-Rich Plasma therapy protocols.

The impact of an open-label design on human amniotic membranes vs. silver sulfadiazine dressings for second-degree burns: a randomized controlled clinical trial

BACKGROUND

Burn wounds require optimal medical management due to associated psycho-emotional and socioeconomic impacts and severe pain. The use of synthetic and biological dressings improves healing and reduces burn wound complications. The present study aimed to compare the outcomes of using human amniotic membrane (hAM) dressings and conventional silver sulfadiazine (SSDZ) ointment dressings in the management of second-degree burn wounds.

METHODS

Fifty patients who participated in this clinical trial were divided into two groups via simple randomization. All the enrolled patients, who had burnt in the last 24 h, had thermal damage mechanisms and were suffering from less than 20% second-degree heat-burn wounds on the skin surface. The target group (n = 25) was treated with hAM, and the control group (n = 25) was treated with SSDZ ointment. The researcher-designed checklist was used to determine the clinical performance in the follow-up assessments on days 7, 14, and 30.

RESULTS

No significant differences were detected in terms of sex, age, or percentage of burn wounds (p > 0.05). Wound epithelialization at days 7, 14, and 30, scar formation, wound pigmentation, pain severity, analgesia requirements, and hospital stay length (on day 30) were significantly lower in the target group (treated with hAM) than in the control group (treated with SSDZ ointment) (p < 0.05). However, treatment costs in the target group ($170) were significantly higher than those in the control group ($71) (p < 0.001).

CONCLUSION

Despite its higher cost, hAM, as a technology-based therapy dressing, demonstrates superiority over SSDZ ointment in terms of wound healing and pain management.

Evaluation of Safety and Efficacy of Cell Therapy Based on Osteoblasts Derived from Umbilical Cord Mesenchymal Stem Cells for Osteonecrosis of the Femoral Head: Study Protocol for a Single-Center, Open-Label, Phase I Clinical Trial

Although mesenchymal stem cells (MSCs) insertion has gained recent attention as a joint-preserving procedure, no study has conducted direct intralesional implantation of human umbilical cord-derived MSCs (hUCMSCs) in patients with ONFH. This is a protocol for a phase 1 clinical trial designed to assess the safety and exploratory efficacy of human umbilical cord-derived osteoblasts (hUC-Os), osteogenic differentiation-induced cells from hUCMSCs, in patients with early-stage ONFH. Nine patients with Association Research Circulation Osseous (ARCO) stage 1 or 2 will be assigned to a low-dose (1 × 107 hUC-O cells, n = 3), medium-dose (2 × 107 cells, n = 3), and high-dose group (4 × 107 cells, n = 3) in the order of their arrival at the facility, and, depending on the occurrence of dose-limiting toxicity, up to 18 patients can be enrolled by applying the 3 + 3 escalation method. We will perform hUC-O (CF-M801) transplantation combined with core decompression and follow-up for 12 weeks according to the study protocol. Safety will be determined through adverse event assessment, laboratory tests including a panel reactive antibody test, vital sign assessment, physical examination, and electrocardiogram. Efficacy will be explored through the change in pain visual analog scale, Harris hip score, Western Ontario and McMaster Universities Osteoarthritis Index, ARCO stage, and also size and location of necrotic lesion according to Japanese Investigation Committee classification before and after the procedure. Joint preservation is important, particularly in younger, active patients with ONFH. Confirmation of the safety and efficacy of hUC-Os will lead to a further strategy to preserve joints for those suffering from ONFH and improve our current knowledge of cell therapy.

A retrospective study of the safety and efficacy of peritoneal dialysis catheter placement under combined local infiltration anesthesia and monitored anesthesia care

OBJECTIVE

Given the lack of global consensus on anesthesia selection for peritoneal dialysis catheter (PDC) placement via open surgery, this study investigates the safety and efficacy of combining local infiltration anesthesia (LIA) with monitored anesthesia care (MAC) in patients with end-stage renal disease (ESRD).

METHODS

This retrospective analysis of ESRD patients who underwent open surgical placement of PDC in the Department of Nephrology, the First Affiliated Hospital of the Army Medical University from 1 August 2020 to 31 May 2022. Patients were categorized into two groups based on anesthesia method: LIA group and LIA + MA group. MA was defined as preoperative sedation (0.2-0.7 µg/kg/h) with dexmedetomidine injection (Huidrican trade name, DEX), and intraoperative analgesia with dexrazoxane injection (Garonin trade name, DEZ) as appropriate according to the patients' pain scores. We compared the general clinical data of the two groups of patients, the changes in blood pressure and heart rate during the whole operation, the intraoperative and postoperative pain, the total duration of the operation and the immediate postoperative complications.

RESULTS

The study included 123 patients (59 in the LIA + MAC group and 64 in the LIA group). The LIA + MA group exhibited lower pain scores measured by Visual Analogue Scale(VAS) during surgery (skin incision, subcutaneous adipose tissue dissection, anterior fascia, muscle traction, posterior fascia, peritoneum, and catheterization) compared to the LIA group(p<0.05). In terms of surgical incisions, to intraoperative pain scores (VRS), the LIA + MA group showed higher score level I and lower score level II compared to the LIA group (p = 0.002, 0.004, respectively). The LIA + MA group experienced lower postoperative resting pain (NRS) and VAS than the LIA group (p = 0.001,0.003, respectively). The surgical duration for the LIA + MA group was shorter than that of the LIA group (p<0.001). Preoperative systolic and diastolic blood pressures (SBP and DBP) were higher in the LIA + MA group compared to the LIA group (p<0.001,<0.001, respectively). Postoperative heart rate and DBP were lower in the LIA + MA group (p<0.001, 0.004, respectively). The LIA + MA group exhibited greater changes in heart rate, SBP, and DBP during and after surgery compared to the LIA group (p = 0.009, <0.001,<0.001, respectively). In terms of immediate postoperative complications, the proportion of patients requiring analgesics within 24 h post-surgery was significantly lower in the LIA + MA group (p = 0.031).

CONCLUSION

Open surgery for PDC placement under LIA + MAC is both safe and effective.

Comparing the effectiveness of pregabalin and gabapentin in patients with lumbar radiculopathy: A systematic review and meta-analysis

BACKGROUND

Gabapentinoids are commonly prescribed to control neuropathic pain of lumbar radiculopathy. Few trials have compared the efficacy of gabapentin (GBP) and pregabalin (PGB). Therefore, the authors conducted a meta-analysis to compare the difference in effect between GBP and PGB in lumbar radiculopathy patients.

METHODS

Articles which were published between January 1, 1960 and May 31, 2023 were investigated via Cochrane Central Register of Controlled Trials, Embase, Google Scholar, and MEDLINE. This meta-analysis was conducted on patients with lumbar radiculopathy. Gabapentin was used as an intervention, and pregabalin as a comparison. As outcomes, pain rating scales including visual analog scale (VAS) and numeric pain rating scale (NRS), and number of adverse events (dizziness and sedation) were obtained.

RESULTS

PGB showed statistically significant improvement in pain scale (VAS and NRS) in short-term follow-up (6 weeks or less) compared to GBP. (Total mean difference of -0.31) However, in the long-term follow-up (6 weeks to 12 weeks), there was no difference in pain reduction effect between two groups. The incidence of AEs showed no difference between two groups.

CONCLUSION

Based on this article, the existing evidence suggests that PGB was more effective in reducing pain of lumbar radiculopathy compared to GBP at the short-term follow-up, but there was no difference in the long-term follow-up. Physicians should consider this finding in prescribing medications for patients with lumbar radiculopathy.

Chronic pain experiences of immigrant Indian women in Canada: A photovoice exploration

Background

Over the past two decades, the prevalence of chronic pain has significantly increased globally, with approximately 20% of the world's population living with pain. Although quantitative measures are useful in identifying pain prevalence and severity, qualitative methods, and especially arts-based ones, are now receiving attention as a valuable means to understand lived experiences of pain. Photovoice is one such method that utilizes individuals' own photography to document their lived experiences.

Aims

The current study utilized an arts-based method to explore immigrant Indian women's chronic pain experiences in Canada and aimed to enhance the understanding of those experiences by creating a visual opportunity for them to share their stories.

Methods

Twelve immigrant Indian women captured photographs and participated in one-on-one interviews exploring daily experiences of chronic pain.

Results

Women's photographs, and description of these photographs, provided a visual entry into their lives and pain experiences. Three themes emerged from our analysis: (1) bodies in pain, (2) traversing spaces including immigration, and (3) pain management methods. Findings revealed that women's representations of pain were shaped by a clash between culturally shaped gender role expectations and changing gender norms due to immigration processes. The use of photovoice visually contextualized and represented pain experiences, proving to be a valuable tool for self-reflection.

Conclusions

This research uncovers the multifaceted nature of chronic pain and identifies the influence of immigration, gender, and social relations on the exacerbation of pain in immigrant Indian women.

The efficacy of patellar denervation on prognosis and kneeling capacity after unicompartmental knee arthroplasty: a randomized clinical trial

OBJECTIVE

The aim of this study was to investigate the effect of patellar denervation (PD) on pain, function and ability to kneel after unicompartmental knee arthroplasty (UKA).

METHODS

Patients with medial knee osteoarthritis who underwent UKA were prospectively selected. Patients were randomly divided into PD and non-PD groups based on whether patellar denervation was performed. Clinical assessment was performed using the Hospital for Special Surgery (HSS) knee score, Kujiala score, visual analogue scale (VAS) and forgotten joint score (FJS-12), as well as postoperative complications were recorded. The patients' postoperative self-perception and actual ability to perform different kneeling positions were assessed in the two groups.

RESULTS

UKA patients treated with PD achieved better Kujiala scores and FJS-12 scores, reduced anterior knee pain and improved kneeling ability postoperatively, validating the effectiveness of PD in UKA. Perception and actual performance of kneeling remained mismatched in PD patients, but performance during different kneeling activities was generally better than in non-PD patients.

TRIAL REGISTRATION

Clinical Trial Registration: ChiCTR1900025669.

CONCLUSION

Patellar denervation can safely and effectively improve patellofemoral joint function, pain and kneeling ability in the early postoperative period after UKA.

Euthymic despite pain: the role of cognitive reappraisal and experiential avoidance in autoimmune inflammatory rheumatic diseases-a cross-sectional study

Pain is a central feature of inflammatory rheumatic diseases and is associated with psychological distress. Pain is widely recognized not as a mere physical sensation, but as a complex, multidimensional phenomenon with an affective component. A plethora of research has conceptualized adaptation to pain by focusing on minimizing the pain experience. However, pain in autoimmune inflammatory rheumatic diseases is often neither avoidable nor curable. This cross-sectional study aimed to investigate the processes explaining how pain intensity may be associated with low well-being and why some patients may live well despite pain. Drawing upon the psychological (in)flexibility model and the process model of emotion regulation, we propose that cognitive reappraisal moderates the association between pain and euthymia through experiential avoidance. Ninety-seven patients with rheumatoid arthritis, psoriatic arthritis, or axial spondyloarthritis were included for analyses (mean age = 53.4; mean time since diagnosis = 9.2 years). Most patients were women (75%), married/cohabitant (71%), and attended high school (47%). Results indicate that experiential avoidance may explain how severe pain is associated with lowered euthymia. This indirect negative effect of pain intensity on euthymia became non-significant at high levels of cognitive reappraisal, suggesting that cognitive reappraisal may serve as a protective factor for patients with autoimmune inflammatory rheumatic diseases. This study paves the way for future research in this promising context by providing an initial step towards integrating emotion regulation and psychological inflexibility in pain conditions.

Perioperative Regional Anesthesia on Persistent Opioid Use and Chronic Pain after Noncardiac Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Whether regional anesthesia impacts the development of chronic postsurgical pain is currently debateable, and few studies have evaluated an effect on prolonged opioid use. We sought to systematically review the effect of regional anesthesia for adults undergoing noncardiac elective surgery on these outcomes.

METHODS

A systematic search was conducted in MEDLINE, EMBASE, CENTRAL, and CINHAL for randomized controlled trials (from inception to April 2022) of adult patients undergoing elective noncardiac surgeries that evaluated any regional technique and included one of our primary outcomes: (1) prolonged opioid use after surgery (continued opioid use ≥2 months postsurgery) and (2) chronic postsurgical pain (pain ≥3 months postsurgery). We conducted a random-effects meta-analysis on the specified outcomes and used the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach to rate the quality of evidence.

RESULTS

Thirty-seven studies were included in the review. Pooled estimates indicated that regional anesthesia had a significant effect on reducing prolonged opioid use (relative risk [RR] 0.48, 95% CI, 0.24-0.96, P = .04, I 2 0%, 5 trials, n = 348 patients, GRADE low quality). Pooled estimates for chronic pain also indicated a significant effect favoring regional anesthesia at 3 (RR, 0.74, 95% CI, 0.59-0.93, P = .01, I 2 77%, 15 trials, n = 1489 patients, GRADE moderate quality) and 6 months (RR, 0.72, 95% CI, 0.61-0.85, P < .001, I 2 54%, 19 trials, n = 3457 patients, GRADE moderate quality) after surgery. No effect was found in the pooled analysis at 12 months postsurgery (RR, 0.44, 95% CI, 0.16-1.17, P = .10).

CONCLUSIONS

The results of this study suggest that regional anesthesia potentially reduces chronic postsurgical pain up to 6 months after surgery. Our findings also suggest a potential decrease in the development of persistent opioid use.

Better diet quality is associated with reduced body pain in adults regardless of adiposity: Findings from the Whyalla Intergenerational Study of Health

Dietary intake has been associated with pain and physical function, but it is unclear if these relationships are mediated by adiposity. Data were derived from the Whyalla Intergenerational Study of Health (n = 654, 57% women). Structural equation modelling tested the hypotheses that adiposity (body mass index (BMI), waist circumference (WC), or body fat (BF, dual energy x-ray absorptiometry)) would mediate the relationship between diet quality (Dietary Guideline Index (DGI) total, core, or non-core scores) and pain (Short Form-36 bodily pain scale (SF36-BPS)), or physical function (grip-strength), overall, and by gender. Adiposity did not mediate a relationship between DGI scores and pain. Direct effects were observed between DGI total scores and SF36-BPS accounting for BMI (β = 0.170, 95% CI 0.002, 0.339), and between DGI core food scores and SF36-BPS (BMI, β = 0.278, 95% CI 0.070, 0.486; WC, β = 0.266, 95% CI 0.058, 0.474; BF, β = 0.266, 95% CI 0.060, 0.473). In women, direct effects existed between DGI scores and SF36-BPS (DGI total scores, BMI, β = 0.388, 95% CI 0.162, 0.613; WC, β = 0.372, 95% CI 0.146, 0.598; BF, β = 0.382, 95% CI 0.158, 0.605, and DGI core scores, BMI, β = 0.482, 95% CI 0.208, 0.757; WC, β = 0.472, 95% CI 0.197, 0.747; BF, β = 0.467, 95% CI 0.195, 0.739), and DGI total scores and grip-strength (BMI, β = 0.075, 95% CI 0.008, 0.142; WC, β = 0.076, 95% CI 0.009, 0.143; BF, β = 0.079, 95% CI 0.011, 0.146). Better diet quality is associated with lower bodily pain, irrespective of adiposity. Findings highlight the potential role of diet quality in pain management and function, particularly in women.

Factors associated with patient-reported mouth opening activity limitations in individuals with persistent intra-articular temporomandibular disorders: A cross-sectional study exploring physical and self-reported outcomes

BACKGROUND

Individuals living with intra-articular temporomandibular disorders (IA-TMDs) often report limitations with mouth opening activities. While clinical measures such as active range of motion (AROM) and movement quality are often used to assess mouth opening function, it is unclear if and how these relate to patient-reported limitations and whether other factors such as kinesiophobia influence mouth opening activities in those with IA-TMDs.

OBJECTIVES

Compare clinical measures of mouth opening function in those with IA-TMDs to asymptomatic controls. In those with an IA/TMD, explore relationships between patient-reported mouth opening limitations, and mouth opening function and kinesiophobia.

DESIGN

Cross-sectional study.

METHOD

Clinical mouth opening function (AROM, movement quality, pain on movement/10, stiffness on movement/10) was compared between groups (n = 30 IA-TMD, n = 30 controls). Within the IA-TMD group, correlations between patient-reported mouth opening limitations (Patient specific functional scale), kinesiophobia (Tampa Scale for Kinesiophobia for Temporomandibular Disorders) and clinical measures of mouth opening function were explored.

RESULTS

Impairments in AROM (-4 mm, p = 0.04, d = 0.5), movement quality (p < 0.01, φ = 0.6), pain on movement (p < 0.01, d = 0.8) and stiffness on movement (p < 0.01, d = 1.6) were observed in the IA-TMD group compared to controls. Patient-reported mouth opening limitations and kinesiophobia were significantly correlated (r = -0.48, p < 0.01); no correlation was found between patient-reported limitations and clinical mouth opening measures (r < 0.3, p > 0.05).

CONCLUSIONS

Mouth opening function is impaired in IA-TMD. However, kinesiophobia appears more related to patient-reported mouth opening limitations than clinical impairments. Consideration of clinical, kinesiophobia and patient-reported limitation measures are necessary to direct management of IA-TMD in those presenting for care.

Patient Engagement in a Mobile App-Based Rehabilitation Program for Total Hip or Knee Arthroplasty: Secondary Data Analysis of a Randomized Controlled Trial

BACKGROUND

Health care professionals use mobile apps to support patients' rehabilitation after total hip or knee arthroplasty. Understanding patient engagement in such mobile health interventions can help tailor these interventions to better support patients.

OBJECTIVE

This study aimed to investigate patient engagement in a mobile app-based arthroplasty rehabilitation program and to investigate the association between patient engagement and their characteristics.

METHODS

Data were extracted from a pool of 42 participants in the experimental arm of a randomized controlled trial that used a mobile app (WeChat [Tencent Holdings Limited])-based program to support patients' rehabilitation after total hip or knee arthroplasty. The primary outcomes were the number of days the participants accessed the program and completed recommended rehabilitation tasks. Secondary outcomes included data on the participants' posts on a discussion forum, messages sent by the participants, access to the program components, and reading and sharing the program content. Generalized linear models were used to analyze the association between patient engagement and personal characteristics.

RESULTS

The participants reported in a rehabilitation diary accessing the program on a mean of 5.2 (SD 2) days per week and completing recommended rehabilitation tasks on a mean of 6.5 (SD 0.8) days per week. The majority (31/42, 74%) posted on the discussion forum, with a mean of 18.1 (SD 21.2) posts. Most participants (37/42, 88%) sent messages to health care professionals, with a mean of 14 (SD 15.9) messages. The program components were visited for a total of 525 times. The program content was read 898 times and shared 82 times in total. Generalized linear models showed that both primary outcomes, the number of days the participants accessed the program (B=6.46, 95% CI 1.98-15.35; χ21=11.1, P=.001) and the number of days they completed rehabilitation tasks (B=2.65, 95% CI 0.45-5.48; χ21=5.7, P=.02), were positively associated with having a high school education or above. In addition, the number of posts on the discussion forum was positively associated with living with family, having a high school education or above, undergoing total knee arthroplasty, having comorbidities, and the score of self-efficacy but was negatively associated with age. The number of messages sent by the participants was positively associated with having a high school education or above, having comorbidities, and the score of self-efficacy.

CONCLUSIONS

Patient engagement in mobile arthroplasty rehabilitation is associated with their education level, cohabitation status, age, type of surgery, presence of comorbidities, and sense of self-efficacy. Program developers can consider these characteristics and use strategies, such as family involvement, in the design of mobile arthroplasty rehabilitation programs to enhance patient engagement in such interventions.

Brain Network Dynamics in Women With Primary Dysmenorrhea During the Pain-Free Periovulation Phase

The human brain is a dynamic system that shows frequency-specific features. Neuroimaging studies have shown that both healthy individuals and those with chronic pain disorders experience pain influenced by various processes that fluctuate over time. Primary dysmenorrhea (PDM) is a chronic visceral pain that disrupts the coordinated activity of brain's functional network. However, it remains unclear whether the dynamic interactions across the whole-brain network over time and their associations with neurobehavioral symptoms are dependent on the frequency bands in patients with PDM during the pain-free periovulation phase. In this study, we used an energy landscape analysis to examine the interactions over time across the large-scale network in a sample of 59 patients with PDM and 57 healthy controls (HCs) at different frequency bands. Compared with HCs, patients with PDM exhibit aberrant brain dynamics, with more significant differences in the slow-4 frequency band. Patients with PDM show more indirect neural transition counts due to an unstable intermediate state, whereas neurotypical brain activity frequently transitions between 2 major states. This data-driven approach further revealed that the brains of individuals with PDM have more abnormal brain dynamics than HCs. Our results suggested that unstable brain dynamics were associated with the strength of brain functional segregation and the Pain Catastrophizing Scale score. Our findings provide preliminary evidence that atypical dynamics in the functional network may serve as a potential key feature and biological marker of patients with PDM during the pain-free phase. PERSPECTIVE: We applied energy landscape analysis on brain-imaging data to identify relatively stable and dominant brain activity patterns for patients with PDM. More atypical brain dynamics were found in the slow-4 band and were related to the strength of functional segregation, providing new insights into the dysfunction brain dynamics.

Evaluation of minimally invasive esthetic crown lengthening using an open flap versus flapless surgical approach: A randomized controlled clinical trial

OBJECTIVES

Esthetic crown lengthening (ECL) is commonly advocated to treat patients with altered passive eruption (APE). Since the introduction of the minimally invasive surgical concept, a limited number of studies have investigated this technique in a standardized manner, with further studies required to verify the validity and predictability of the minimally invasive FL-technique. The current randomized trial compares a minimally invasive (ECL), using piezosurgery with flapless-approach (FL), versus an open-flap (OF) approach in the management of patients with APE Type 1B.

MATERIALS AND METHODS

Twenty-four patients diagnosed with APE Type 1B were randomly assigned into test (FL) with tunneling approach or control (OF) group with minimally invasive flap reflection (n = 12/group). Postoperative pain was assessed during the first 48 h. Gingival margin (GM) level relative to a custom-made stent (rGM) and patient satisfaction were assessed preoperative, immediately after surgery, at 3 and 6 months postsurgically. Postoperative swelling was reported for the first week postsurgically. Plaque index (PI), bleeding on probing (BoP), clinical attachment level (CAL), pocket depth (PD) and pink esthetic score (PES), were evaluated at baseline and 6 months. Linear regression analysis was conducted for pain.

RESULTS

OF-group reported significantly higher pain and swelling scores than FL-group during the first 48 h (p < 0.05). FL-group showed no significant differences regarding rGM between 3 and 6 months, in contrast to OF-group, where a significant decrease in rGM was notable (p < 0.05). No significant differences in PI, BoP, CAL, PD, PES, and patient satisfaction scores were evident between groups (p > 0.05). Regression analysis demonstrated that treatment and gender were significant predictors for pain (p < 0.05).

CONCLUSIONS

Within the current study's limitations, piezo-surgical ECL with FL-approach presented significantly lower postoperative pain, swelling, and early GM stability compared to OF-approach.

CLINICAL SIGNIFICANCE

Piezosurgical ECL with a FL-approach can be considered a predictable technique with advantages over the OF-approach in the management of patients with APE Type1B.

Developing a Motion Sensor-Based Game to Support Frozen Shoulder Rehabilitation in Older Adults through a Participatory Design Approach

Objective: Although some serious games have been developed for physical therapy, little work has been conducted through a participatory design approach. Therefore, a game prototype was developed, which involved related stakeholders in the design process. Materials and Methods: The iterative participatory design process was adopted with the input of 18 patients with frozen shoulder symptoms, 4 health professionals, 2 game designers, and 5 researchers in an iterative process to design, test, and evaluate the game prototype. In total, 17 patients participated in the interviews to explore their needs and desires for a serious game. The health professionals participated in the interviews to understand the medical requirement and experience pertaining to frozen shoulder and were included in the workshop to give feedback on the game prototype. At the conclusion of the iterative design process, a Kinect-based prototype game with three levels was used for a case study with one patient who was diagnosed with frozen shoulder and has been receiving medical treatment in the hospital. Results: Based on the outcomes derived from data collected among diverse stakeholders, the prototype game underwent iterative development by the team and was assessed by a participant with frozen shoulder symptoms. Findings revealed that the participant demonstrated enhanced shoulder mobility and a reduction in pain intensity, despite the lack of significant improvement for health-related quality of life. Nevertheless, the participant reported a positive experience with the prototype game. Conclusion: This study underscores the importance of involving diverse stakeholders in the development process to create more effective and user-centric serious games for rehabilitation. The participatory approach, exemplified by the prototype game, demonstrates potential improvements in both user experience and overall effectiveness during the rehabilitation process.

Comparison of cognitive behaviour therapy versus activity management, both delivered remotely, to treat paediatric chronic fatigue syndrome/myalgic encephalomyelitis: the UK FITNET-NHS RCT

Design

Parallel-group randomised controlled trial.

Methods

Adolescents aged 11-17 years, diagnosed with myalgic encephalomyelitis/chronic fatigue syndrome and with no local specialist treatment centre, were referred to a specialist service in South West England.

Interventions

Fatigue In Teenagers on the interNET in the National Health Service is a web-based myalgic encephalomyelitis/chronic fatigue syndrome-focused cognitive-behavioural therapy programme for adolescents, supported by individualised written, asynchronous electronic consultations with a clinical psychologist/cognitive-behavioural therapy practitioner. The comparator was videocall-delivered activity management with a myalgic encephalomyelitis/chronic fatigue syndrome clinician. Both treatments were intended to last 6 months.

Objectives

Estimate the effectiveness of Fatigue In Teenagers on the interNET in the National Health Service compared to Activity Management for paediatric myalgic encephalomyelitis/chronic fatigue syndrome. Estimate the effectiveness of Fatigue In Teenagers on the interNET in the National Health Service compared to Activity Management for those with mild/moderate comorbid mood disorders. From a National Health Service perspective, estimate the cost-effectiveness of Fatigue In Teenagers on the interNET in the National Health Service compared to Activity Management over a 12-month horizon.

Primary Outcome

36-item Short Form Health Survey Physical Function subscale at 6 months post randomisation.

Randomisation

Web-based, using minimisation with a random component to balance allocated groups by age and gender.

Blinding

While the investigators were blinded to group assignment, this was not possible for participants, parents/carers and therapists.

Results

The treatment of 314 adolescents was randomly allocated, 155 to Fatigue In Teenagers on the interNET in the National Health Service. Mean age was 14 years old and 63% were female.

Primary outcome

At 6 months, participants allocated to Fatigue In Teenagers on the interNET in the National Health Service were more likely to have improved physical function (mean 60.5, standard deviation 29.5, n = 127) compared to Activity Management (mean 50.3, standard deviation 26.5, n = 138). The mean difference was 8.2 (95% confidence interval 2.7 to 13.6, p = 0.003). The result was similar for participants meeting the National Institute for Health and Care Excellence 2021 diagnostic criteria.

Secondary outcomes

Fatigue In Teenagers on the interNET in the National Health Service participants attended, on average, half a day more school per week at 6 months than those allocated Activity Management, and this difference was maintained at 12 months. There was no strong evidence that comorbid mood disorder impacted upon the relative effectiveness of the two interventions. Similar improvement was seen in the two groups for pain and the Clinical Global Impression scale, with a mixed picture for fatigue. Both groups continued to improve, and no clear difference in physical function remained at 12 months [difference in means 4.4 (95% confidence interval -1.7 to 10.5)]. One or more of the pre-defined measures of a worsening condition in participants during treatment, combining therapist and patient reports, were met by 39 (25%) participants in the Fatigue In Teenagers on the interNET in the National Health Service group and 42 (26%) participants in the Activity Management group. A small gain was observed for the Fatigue In Teenagers on the interNET in the National Health Service group compared to Activity Management in quality-adjusted life-years (0.002, 95% confidence interval -0.041 to 0.045). From an National Health Service perspective, the costs were £1047.51 greater in the Fatigue In Teenagers on the interNET in the National Health Service group (95% confidence interval £624.61 to £1470.41). At a base cost-effectiveness threshold of £20,000 per quality-adjusted life-year, the incremental cost-effectiveness ratio was £457,721 with incremental net benefit of -£1001 (95% confidence interval -£2041 to £38).

Conclusion

At 6 months post randomisation, compared with Activity Management, Fatigue In Teenagers on the interNET in the National Health Service improved physical function and school attendance. The additional cost of Fatigue In Teenagers on the interNET in the National Health Service and limited sustained impact mean it is unlikely to be cost-effective.

Dataset on bilateral idiopathic carpal tunnel syndrome: Crossover study of two combined physiotherapeutic treatment methods on chirurgical and clinical patients

This study presents a randomized controlled crossover experiment involving 73 patients with idiopathic bilateral Carpal Tunnel Syndrome (CTS). Patients received two combined physiotherapeutic treatments: myofascial mobilization (IASTM) and stretching. Participants were divided into two groups: one started with stretching followed by IASTM, and the other with IASTM followed by stretching. Of these, 43 underwent surgery and began physical therapy 30 days post-operation, while 30 received non-surgical treatment. The therapy sessions lasted four weeks, followed by a crossover of the treatment modalities and periodic reassessments up to six months. The dataset includes experimental design, patient demographics, diagnostic data, objective muscle strength tests, subjective sensitivity tests, clinical indicators, and self-reported measures. This data can be useful for researchers looking to replicate the study or compare outcomes between clinical and surgical CTS patients.

Pain intensity scales: A cross-sectional study on the preferences and knowledge of physiotherapists and participants with musculoskeletal pain

BACKGROUND

Subjective pain intensity can be measured using instruments like the Faces Pain Scale-Revised (FPS-R), Verbal Rating Scale (VRS), Numerical Pain Rating Scale (NPRS), and Visual Analogue Scale (VAS). However, information on physiotherapists' and patients' knowledge and preference for these tools is scarce.

OBJECTIVE

We investigated the knowledge and preference of physiotherapists and participants with musculoskeletal pain (MP) regarding the pain intensity measurement scales.

METHODS

This cross-sectional study consisted of physiotherapists and participants with MP. Physiotherapists were recruited via social media for an online open survey, gathering sociodemographic, professional data, and their knowledge and preferences for pain intensity scales. Participants over 18 with MP, participated in interviews focusing on their familiarity and preferences for pain intensity scales. Data was analyzed descriptively, and Chi-squared test evaluated scale preferences.

RESULTS

We included 352 physiotherapists (mean experience = 10.5 years) and 94 participants with MP. Of the physiotherapists, 94.3% were familiar with pain scales, but 30.4% struggled to differentiate them. The NPRS was the most used (56.3%) and preferred scale (52.4%). Among participants with MP, unfamiliarity was noted with all scales. After instruction, 46% preferred FPS-R, with preference varying by income and education levels (p < 0.001).

CONCLUSION

We found a knowledge gap among physiotherapists in identifying pain intensity scales, with a preference for the NPRS among those familiar with the scales. Participants with MP had limited familiarity with these scales. After instructions, these participants preferred the FPS-R, particularly those with lower income and education levels.

Normality analysis of numeric rating scale scores in patients with chronic axial spine pain before and after medial branch blocks: a multicenter study

OBJECTIVE

The statistical analysis typically used to compare pain before and after interventions assumes that scores are normally distributed. The present study evaluates whether numeric rating scale (NRS) scores, specifically NRS-11 scores, are indeed normally distributed in a clinically relevant cohort of adults with chronic axial spine pain before and after analgesic intervention.

METHODS

Retrospective review from 4 academic medical centers of prospectively collected data from a uniform pain diary administered to consecutive patients after they had undergone medial branch blocks. The pain diary assessed NRS-11 scores immediately before injection and at 12 different time points after injection up to 48 hours. D'Agostino-Pearson tests were used to test normality at all time points.

RESULTS

One hundred fifty pain diaries were reviewed, and despite normally distributed pre-injection NRS-11 scores (K2 = 0.655, P = .72), all post-injection NRS-11 data were not normally distributed (K2 = 9.70- 17.62, P = .0001-.008).

CONCLUSIONS

Although the results of parametric analyses of NRS-11 scores are commonly reported in pain research, some properties of the NRS-11 do not satisfy the assumptions required for these analyses. The data demonstrate non-normal distributions in post-intervention NRS-11 scores, thereby violating a key requisite for parametric analysis. We urge pain researchers to consider appropriate statistical analysis and reporting for non-normally distributed NRS-11 scores to ensure accurate interpretation and communication of these data. Practicing pain physicians should similarly recognize that parametric post-intervention pain score statistics might not accurately describe the data and should expect articles to utilize measures of normality to justify the selected statistical methods.

Long-Term Patient-Reported Outcomes following Proximal Row Carpectomy

Background  Proximal row carpectomy (PRC) is a procedure used for pain relief from arthrosis that preserves some degree of range of motion (ROM). Dorsal capsular interposition (DCI) is an option for cases where some chondral loss of the capitate is present. Purposes  The aim of this study is to assess what factors influence long-term patient-reported outcomes following PRC and specifically to evaluate the role of DCI. Additionally, this study aims to report the long-term postoperative ROM in patients with DCI. Methods  Patients who underwent PRC in the period between 2002 and 2017 were retrospectively identified, resulting in a cohort of 162 patients. Patient-reported outcomes were obtained using validated questionnaires and were completed by 59 patients at a median follow-up time of 8.5 years (interquartile range [IQR]: 6.0-13). Multivariable linear regression was performed to identify factors independently associated with patient-reported outcomes. Results  The median PRWE (Patient-Rated Wrist Evaluation) score was 17 (IQR: 5.5-52), the median QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand) score was 16 (IQR: 4.5-39), and the median NRS (Numeric Rating Scale) Pain score was 1 (IQR: 0-3). The mean flexion-extension ROM was 70 ± 24 degrees. After correcting for gender, involvement of the capitate cartilage was independently associated with worse QuickDASH scores. Conclusions  PRC is associated with good functional outcomes and pain control at long-term follow-up. This generally also applied to patients who underwent DCI; however, the role of DCI in those with capitate cartilage injury remains unclear. Preexistent damage to the capitate cartilage was associated with worse QuickDASH scores. Level of Evidence  II, Prognostic study.

Pilot Study of Intensive Trismus Intervention Using Restorabite™ During Unilateral Adjuvant Radiation for Head and Neck Cancer

Trismus commonly arises after surgery for head and neck cancer (HNC) and its severity is potentiated by postoperative radiotherapy. While the benefit of trismus rehabilitation after surgery and radiotherapy is well established, the evidence during radiotherapy is less clear. This may be due to poor adherence to trismus exercises secondary to acute mucositis. This study assessed the feasibility of using a novel trismus device during adjuvant radiotherapy for HNC in patients with acute postoperative trismus. Prospective single-arm cohort feasibility study. Eligible patients had undergone surgery with curative intent for HNC, planned for adjuvant radiotherapy, and were suitable for trismus rehabilitation. Participants completed a 10-week exercise program using a novel jaw stretching device. Study outcomes were adherence, maximal incisal opening (MIO), and trismus-related function and quality of life scores, assessed at baseline, 10 weeks, and 6 months after commencing exercises. Nine patients diagnosed with trismus after primary surgery were recruited. The mean increase in MIO at 10 weeks was 7.8 mm (range -4 to 15 mm, p = 0.03), and at 6 months was 10.6 mm (range 1-26 mm, p = 0.03). Significant improvements were observed in trismus-related quality of life (Gothenburg Trismus Questionnaire; p = 0.04). Adherence to the exercises was 100% in week 1-2, 67% in weeks 3-6, and 100% at 10 weeks (1 month post radiation). This study demonstrates the feasibility of using a novel jaw stretching device during adjuvant radiotherapy. Further evaluation is warranted to assess the effectiveness of early intervention and prevention of trismus during HNC radiotherapy.Level of Evidence: IV.

More Than Just a Pain in the Back: Pain Among American Nurses and Its Relationship to Modifiable Work Factors and Work Performance

Nursing is a profession with high rates of workplace injuries, hazards, and turnover. Improving the health and safety of nurses at work is vital to retain and grow the workforce to meet future demands. The purpose of this study was to describe the breadth of pain among American nurses and explore the relationships between this pain and modifiable work factors and perceived work performance. We used a cross-sectional descriptive design of 2312 nurses from across the United States. Nurses completed a survey containing questions about demographics, the presence of pain in the past week, the number of pain sites, pain locations, severity, and the impact on work performance. The median number of pain locations reported was 2, back pain was the most reported pain site, and average pain severity ranged from 4 to 5. Significant modifiable work factors associated with pain were average patient load and shift length. Many participants indicated that their pain impacted work performance, while a smaller proportion acknowledged that their pain impacted patient care. Pain among nurses spans multiple locations, is moderately severe, and impacts work performance. Addressing related modifiable work factors may decrease pain and the impact on the health, safety, and work performance of the nursing workforce.

Is chemodenervation with incobotulinumtoxinA an alternative to invasive chronic anal fissure treatments?

BACKGROUND

Botulinum toxin type A is currently strongly recommended for the treatment of anal fissures (AFs). However, there is still no consensus on dosage or injection technique. This study provides further efficacy and safety evidence in a 2-year follow-up.

METHOD

Prospective, open-label, single-arm, single-center study carried out in adult patients with AFs non-responsive to previous treatments. Patients were treated with incobotulinumtoxinA (incoBoNT/A) injected in both laterals and posterior intersphincteric groove. Healing rate at 2 years was the primary endpoint. Secondary endpoints included internal anal sphincter pressures, incontinence, and safety.

RESULTS

A total of 49 patients were treated with a mean incoBoNT/A dose of 40.5 U (spread across three locations). Healing rate at 2 years was 83.9% with a 24.5% of recurrence throughout the study. Only 7 patients (14.3%) reported adverse events (AEs) that were mild and temporary. Mean reduction in anal resting pressure was -9.1 mmHg at 3 months (p = 0.001). Mean reduction in voluntary squeeze pressure was -27.5 mmHg at 3 months (p < 0.001). Mean pain perception measured with a visual analog scale decreased by -6.5 points at 2 years (p < 0.001). There was an incontinence increase at 1 month of 1.3 points (p = 0.006), but baseline values were restored at 6 months.

CONCLUSION

We present results that support the use of incoBoNT/A as a second line for AFs that do not respond to ointment therapy. IncoBoNT/A injection is a less invasive treatment that should be considered before surgery due to its efficacy and its safety which includes no permanent impairment.

Functional Magnetic Resonance Imaging Analysis of the Clinical Effect and Cerebral Mechanism of Tuina in Lumbar Disc Herniation: Protocol for a Randomized Controlled Parallel Group Trial

BACKGROUND

Lumbar disc herniation (LDH) has become a serious public health and socioeconomic problem. Tuina is a Chinese medicine treatment method based on meridian acupuncture theory and modern anatomy. Tuina can relieve pain and muscle tension and improve functional disorders; this massage is performed by pressing, kneading, pushing, pulling, and shaking the skin, muscles, and bones. However, the mechanism of action and the effect of Tuina as an external treatment on the activities of the central nervous system to relieve LDH pain is unclear. Therefore, we performed functional magnetic resonance imaging (fMRI), which is widely used in pain-related research, as it can detect the effects of different types of pain on brain activity.

OBJECTIVE

Our randomized controlled parallel-group trial aims to compare the effects of Tuina with those of transcutaneous electrical nerve stimulation (TENS) with traction in patients with LDH.

METHODS

This trial will be conducted between May 2024 and April 2025 in the Rehabilitation Hospital affiliated to Fujian University of Traditional Chinese Medicine. Seventy-six participants with LDH will be enrolled for this trial and randomly assigned to 2 groups: Tuina intervention group and TENS with traction intervention group. Participants in both groups will receive treatment for 14 days. fMRI will be performed for the main pain measurements by assessing the effect of the intervention on brain activity before and after the end of the intervention. Short-Form McGill Pain Questionnaire, pressure pain thresholds, and the Oswestry disability index will be used to reflect the degree of pain and lumbar dysfunction, and the results will be used as secondary outcome measurements.

RESULTS

The study protocol has been approved by the ethics review committee of The Rehabilitation Hospital affiliated to Fujian University of Traditional Chinese Medicine. This study was registered on May 1, 2024, with the Chinese Clinical Trial Registry. Data collection began on May 2024 and is expected to end on April 2025. Currently, data from this trial are in the collection phase, and no data analysis has been performed. As of July 1, 2024, we have collected data from 21 patients. The results of this trial are expected to be submitted for publication in September 2025.

CONCLUSIONS

This clinical trial will compare the effectiveness of Tuina with that of TENS with traction in the treatment of patients with LDH and will show the cerebral mechanism of Tuina in LDH treatment by using fMRI. The results of our trial will be helpful in clarifying the cerebral mechanism of Tuina in the treatment of LDH and provide a solid foundation for Tuina therapy research.
