Shoulder-specific rehabilitation combined with aerobic exercises versus solely shoulder-specific rehabilitation in patients with type 2 diabetes mellitus: study protocol for a randomized controlled superiority trial

Background

Musculoskeletal disorders are very common in patients with diabetes mellitus (DM). The upper limb is one of the regions that is most frequently affected generally presenting limited joint mobility, pain, and a decreased muscle strength. Most clinical trials with a focus on shoulder musculoskeletal rehabilitation are carried out in patients who do not present DM. Thus, the purpose of the present study is to compare the effects of two distinct treatment protocols (conventional shoulder musculoskeletal rehabilitation combined with aerobic exercises versus solely conventional shoulder musculoskeletal rehabilitation) on shoulder pain, function, strength, kinematics, and supraspinatus tendon thickness in patients with type 2 DM after 12 weeks of intervention and a subsequent follow-up at week 20.

Methods

A randomized controlled superiority trial will be conducted. Participants with a clinical diagnosis of type 2 DM of both sexes, age between 40 and 70 years, presenting shoulder pain will be randomly assigned to one of the following groups: (1) conventional shoulder musculoskeletal rehabilitation combined with aerobic exercises; (2) solely conventional shoulder musculoskeletal rehabilitation. All individuals will be evaluated before starting the treatment protocol (baseline) and at the end of treatment (post 12 weeks) and as a follow-up at 20 weeks. The shoulder function assessed by the SPADI (Shoulder Pain and Disability Index) questionnaire will be considered as primary outcome; the secondary outcome will be shoulder pain, measured with NPRS scales. Other outcomes will include range of motion, measured using a digital inclinometer; isometric shoulder muscle strength, measured using a manual muscle dynamometer; shoulder kinematics, measured using three-dimensional inertial units measurement; supraspinatus tendon thickness, measured using an ultrasound; AGE accumulation, using a skin autofluorescence measurement; and HbA1c (hemoglobin a1c), fasting glucose and lipid profile measured by a simple blood test.

Discussion

DM is a highly prevalent disease and a public health problem worldwide, and the upper extremity musculoskeletal disorders in DM are barely recognized and largely underestimated. In this way, it would be interesting to analyze if the combination of aerobic exercises with conventional musculoskeletal rehabilitation protocols could generate better results in the functionality, pain, mobility and an improvement in the biochemical aspects related to the hyperglycemia of these patients compared to solely the conventional musculoskeletal rehabilitation.

Clinical Outcomes After a Digital Musculoskeletal Program for Acute and Subacute Pain: Observational, Longitudinal Study With Comparison Group

Background

Telerehabilitation for musculoskeletal (MSK) conditions may produce similar or better outcomes than usual care, but most telerehabilitation studies address only chronic or postsurgical pain.

Objective

We aimed to examine pain and function at 3, 6, and 12 weeks for individuals with acute and subacute MSK pain who took part in a digital MSK program versus a nonparticipant comparison group.

Methods

We conducted an observational, longitudinal study with a nonparticipant comparison group. The intervention group had video visits with physical therapists who recommended exercise therapies and educational articles delivered via an app. Nonparticipants were those who were registered but unable to participate because their benefit coverage had not yet begun. We collected pain and function outcomes through surveys delivered at 3-, 6-, and 12-week follow-ups. We conducted descriptive analyses, unadjusted regression, and mixed effects regression adjusting for baseline characteristics, time as fixed effects, and a time*group interaction term.

Results

The analysis included data from 675 nonparticipants and 262 intervention group participants. Compared to baseline, the intervention group showed significantly more pain improvement at 3, 6, and 12 weeks versus nonparticipants after adjusting for baseline factors. Specifically, the intervention group’s pain scores decreased by 55.8% at 3 weeks versus baseline, 69.1% at 6 weeks, and 73% at 12 weeks. The intervention group’s adjusted pain scores decreased from 43.7 (95% CI 41.1-46.2) at baseline to 19.3 (95% CI 16.8-21.8) at 3 weeks to 13.5 (95% CI 10.8-16.2) at 6 weeks to 11.8 (95% CI 9-14.6) at 12 weeks. In contrast, nonparticipants’ pain scores decreased by 30.8% at 3 weeks versus baseline, 45.8% at 6 weeks, and 46.7% at 12 weeks. Nonparticipants’ adjusted pain scores decreased from 43.8 (95% CI 42-45.5) at baseline to 30.3 (95% CI 27.1-33.5) at 3 weeks to 23.7 (95% CI 20-27.5) at 6 weeks to 23.3 (95% CI 19.6-27) at 12 weeks. After adjustments, the percentage of participants reporting that pain was better or much better at follow-up was significantly higher by 40.6% at 3 weeks, 31.4% at 6 weeks, and 31.2% at 12 weeks for intervention group participants versus nonparticipants. After adjustments, the percentage of participants with meaningful functional improvement at follow-up was significantly higher by 15.2% at 3 weeks and 24.6% at 12 weeks for intervention group participants versus nonparticipants.

Conclusions

A digital MSK program may help to improve pain and function in the short term among those with acute and subacute MSK pain.

Dynamic postural control and physical stress: an approach to determining injury risk in real sporting conditions

Dynamic postural control is one of the essential factors in situations where non-contact injuries mainly occur, i.e., landing, cutting, or stopping. Therefore, testing of dynamic postural control should be implemented in injury risk assessment. Moreover, non-contact injuries mainly occur under loaded conditions when the athlete is physically stressed. Therefore, risk factors and mechanisms of these injuries should also be regarded under loading conditions and not only when the athlete is recovered. Current studies examining the influence of physical load on risk factors, such as dynamic postural control, often use cycling protocols to stress the participants. Nevertheless, most types of sports require running as a central element and the induced internal load after cycling might not be the same after running. Therefore, the current study aimed to examine the influence of a running and a cycling protocol on dynamic postural control and to determine the potential injury risk under representative conditions. In total, 128 sport students (64 males and 64 females, age: 23.64 ± 2.44, height: 176.54 ± 8.96 cm, weight: 68.85 ± 10.98 kg) participated in the study. They were tested with the Y Balance Test before and after one loading protocol. A total of 64 participants completed a protocol on a cycle ergometer and the other 64 on a treadmill. A mixed ANOVA showed significant interactions of time and load type. Dynamic postural control was reduced immediately after cycling but did not change after running. These findings indicate a load type dependence of dynamic postural control that must be considered while assessing an athlete’s potential injury risk and they support the need for more representative designs.

Interventions for treating proximal humeral fractures in adults

BACKGROUND

Fractures of the proximal humerus, often termed shoulder fractures, are common injuries, especially in older people. The management of these fractures varies widely, including in the use of surgery. This is an update of a Cochrane Review first published in 2001 and last updated in 2015.

OBJECTIVES

To assess the effects (benefits and harms) of treatment and rehabilitation interventions for proximal humeral fractures in adults.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, trial registries, and bibliographies of trial reports and systematic reviews to September 2020. We updated this search in November 2021, but have not yet incorporated these results.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials that compared non-pharmacological interventions for treating acute proximal humeral fractures in adults.  DATA COLLECTION AND ANALYSIS: Pairs of review authors independently selected studies, assessed risk of bias and extracted data. We pooled data where appropriate and used GRADE for assessing the certainty of evidence for each outcome. We prepared a brief economic commentary for one comparison.

MAIN RESULTS

We included 47 trials (3179 participants, mostly women and mainly aged 60 years or over) that tested one of 26 comparisons. Six comparisons were tested by 2 to 10 trials, the others by small single-centre trials only. Twelve studies evaluated non-surgical treatments, 10 compared surgical with non-surgical treatments, 23 compared two methods of surgery, and two tested timing of mobilisation after surgery. Most trials were at high risk of bias, due mainly to lack of blinding. We summarise the findings for four key comparisons below. Early (usually one week post injury) versus delayed (after three or more weeks) mobilisation for non-surgically-treated fractures Five trials (350 participants) made this comparison; however, the available data are very limited. Due to very low-certainty evidence from single trials, we are uncertain of the findings of better shoulder function at one year in the early mobilisation group, or the findings of little or no between-group difference in function at 3 or 24 months. Likewise, there is very low-certainty evidence of no important between-group difference in quality of life at one year. There was one reported death and five serious shoulder complications (1.9% of 259 participants), spread between the two groups, that would have required substantive treatment. Surgical versus non-surgical treatment Ten trials (717 participants) evaluated surgical intervention for displaced fractures (66% were three- or four-part fractures). There is high-certainty evidence of no clinically important difference between surgical and non-surgical treatment in patient-reported shoulder function at one year (standardised mean difference (SMD) 0.10, 95% confidence interval (CI) -0.07 to 0.27; 7 studies, 552 participants) and two years (SMD 0.06, 95% CI -0.13 to 0.25; 5 studies, 423 participants). There is moderate-certainty evidence of no clinically important between-group difference in patient-reported shoulder function at six months (SMD 0.17, 95% CI -0.04 to 0.38; 3 studies, 347 participants). There is high-certainty evidence of no clinically important between-group difference in quality of life at one year (EQ-5D (0: dead to 1: best quality): mean difference (MD) 0.01, 95% CI -0.02 to 0.04; 6 studies, 502 participants). There is low-certainty evidence of little between-group difference in mortality: one of the 31 deaths was explicitly linked with surgery (risk ratio (RR) 1.35, 95% CI 0.70 to 2.62; 8 studies, 646 participants). There is low-certainty evidence of a higher risk of additional surgery in the surgery group (RR 2.06, 95% CI 1.21 to 3.51; 9 studies, 667 participants). Based on an illustrative risk of 35 subsequent operations per 1000 non-surgically-treated patients, this indicates an extra 38 subsequent operations per 1000 surgically-treated patients (95% CI 8 to 94 more). Although there was low-certainty evidence of a higher overall risk of adverse events after surgery, the 95% CI also includes a slightly increased risk of adverse events after non-surgical treatment (RR 1.46, 95% CI 0.92 to 2.31; 3 studies, 391 participants). Open reduction and internal fixation with a locking plate versus a locking intramedullary nail Four trials (270 participants) evaluated surgical intervention for displaced fractures (63% were two-part fractures). There is low-certainty evidence of no clinically important between-group difference in shoulder function at one year (SMD 0.15, 95% CI -0.12 to 0.41; 4 studies, 227 participants), six months (Disability of the Arm, Shoulder, and Hand questionnaire (0 to 100: worst disability): MD -0.39, 95% CI -4.14 to 3.36; 3 studies, 174 participants), or two years (American Shoulder and Elbow Surgeons score (ASES) (0 to 100: best outcome): MD 3.06, 95% CI -0.05 to 6.17; 2 studies, 101 participants). There is very low-certainty evidence of no between-group difference in quality of life (1 study), and of little difference in adverse events (4 studies, 250 participants) and additional surgery (3 studies, 193 participants). Reverse total shoulder arthroplasty (RTSA) versus hemiarthroplasty There is very low-certainty evidence from two trials (161 participants with either three- or four-part fractures) of no or minimal between-group differences in self-reported shoulder function at one year (1 study) or at two to three years' follow-up (2 studies); or in quality of life at one year or at two or more years' follow-up (1 study). Function at six months was not reported. Of 10 deaths reported by one trial (99 participants), one appeared to be surgery-related. There is very low-certainty evidence of a lower risk of complications after RTSA (2 studies). Ten people (6.2% of 161 participants) had a reoperation; all eight cases in the hemiarthroplasty group received a RTSA (very low-certainty evidence).

AUTHORS' CONCLUSIONS

There is high- or moderate-certainty evidence that, compared with non-surgical treatment, surgery does not result in a better outcome at one and two years after injury for people with displaced proximal humeral fractures. It may increase the need for subsequent surgery. The evidence is absent or insufficient for people aged under 60 years, high-energy trauma, two-part tuberosity fractures or less common fractures, such as fracture dislocations and articular surface fractures. There is insufficient evidence from randomised trials to inform the choices between different non-surgical, surgical or rehabilitation interventions for these fractures.

The Efficacy of Pain Neuroscience Education on Active Rehabilitation Following Arthroscopic Rotator Cuff Repair: A CONSORT-Compliant Prospective Randomized Single-Blind Controlled Trial

Pain neuroscience education (PNE), a modern educational therapy, has been reported to be effective in pain control by reducing fear of movement. This study investigated the effects of additional PNE on a physical therapy rehabilitation protocol (PTRP) following arthroscopic rotator cuff repair (ARCR). In this single-blind, randomized controlled trial, 34 patients who had undergone ARCR were randomly allocated (1:1) into two groups: PNE (PTRP plus PNE) and PTRP. PTRP was performed five times a week, for four weeks, 115 min per session (physical agents, manual therapy, and exercises), and PNE was performed twice at the beginning (face-to-face PNE) and end (non-face-to-face) of the PTRP. The outcome measures were measured four times for pain intensity, pain cognition, and shoulder function; two times for a range of motion; and once for satisfaction. No significant difference in pain intensity was observed between the groups. However, in pain cognition, the Tampa Scale for Kinesiophobia avoidance showed a significant interaction between time and group, and PNE showed a higher effect size than PTRP in the post-test and follow-up in several variables. In conclusion, the significant improvement in avoidance in postoperative rehabilitation suggests that there is a partially positive benefit in terms of pain, range of motion, and shoulder function in ARCR patients.

What Are the Minimally Important Changes of Four Commonly Used Patient-reported Outcome Measures for 36 Hand and Wrist Condition-Treatment Combinations?

BACKGROUND

Patient-reported outcome measures (PROMs) are frequently used to assess treatment outcomes for hand and wrist conditions. To adequately interpret these outcomes, it is important to determine whether a statistically significant change is also clinically relevant. For this purpose, the minimally important change (MIC) was developed, representing the minimal within-person change in outcome that patients perceive as a beneficial treatment effect. Prior studies demonstrated substantial differences in MICs between condition-treatment combinations, suggesting that MICs are context-specific and cannot be reliably generalized. Hence, a study providing MICs for a wide diversity of condition-treatment combinations for hand and wrist conditions will contribute to more accurate treatment evaluations.

QUESTIONS/PURPOSES

(1) What are the MICs of the most frequently used PROMs for common condition-treatment combinations of hand and wrist conditions? (2) Do MICs vary based on the invasiveness of the treatment (nonsurgical treatment or surgical treatment)?

METHODS

This study is based on data from a longitudinally maintained database of patients with hand and wrist conditions treated in one of 26 outpatient clinics in the Netherlands between November 2013 and November 2020. Patients were invited to complete several validated PROMs before treatment and at final follow-up. All patients were invited to complete the VAS for pain and hand function. Depending on the condition, patients were also invited to complete the Michigan Hand outcomes Questionnaire (MHQ) (finger and thumb conditions), the Patient-rated Wrist/Hand Evaluation (PRWHE) (wrist conditions), or the Boston Carpal Tunnel Questionnaire (BCTQ) (nerve conditions). Additionally, patients completed the validated Satisfaction with Treatment Result Questionnaire at final follow-up. Final follow-up timepoints were 3 months for nonsurgical and minor surgical treatment (including trigger finger release) and 12 months for major surgical treatment (such as trapeziectomy). Our database included 55,651 patients, of whom we excluded 1528 who only required diagnostic management, 25,099 patients who did not complete the Satisfaction with Treatment Result Questionnaire, 3509 patients with missing data in the PROM of interest at baseline or follow-up, and 1766 patients who were part of condition-treatment combinations with less than 100 patients. The final sample represented 43% (23,749) of all patients and consisted of 36 condition-treatment combinations. In this final sample, 26% (6179) of patients were managed nonsurgically and 74% (17,570) were managed surgically. Patients had a mean ± SD age of 55 ± 14 years, and 66% (15,593) of patients were women. To estimate the MIC, we used two anchor-based methods (the anchor mean change and the MIC predict method), which were triangulated afterward to obtain a single MIC. Applying this method, we calculated the MIC for 36 condition-treatment combinations, comprising 22 different conditions, and calculated the MIC for combined nonsurgical and surgical treatment groups. To examine whether the MIC differs between nonsurgical and surgical treatments, we performed a Wilcoxon signed rank test to compare the MICs of all PROM scores between nonsurgical and surgical treatment.

RESULTS

We found a large variation in triangulated MICs between the condition-treatment combinations. For example, for nonsurgical treatment of hand OA, the MICs of VAS pain during load clustered around 10 (interquartile range 8 to 11), for wrist osteotomy/carpectomy it was around 25 (IQR 24 to 27), and for nerve decompression it was 21. Additionally, the MICs of the MHQ total score ranged from 4 (nonsurgical treatment of CMC1 OA) to 15 (trapeziectomy with LRTI and bone tunnel), for the PRWHE total score it ranged from 2 (nonsurgical treatment of STT OA) to 29 (release of first extensor compartment), and for the BCTQ Symptom Severity Scale it ranged from 0.44 (nonsurgical treatment of carpal tunnel syndrome) to 0.87 (carpal tunnel release). An overview of all MIC values is available in a freely available online application at: https://analyse.equipezorgbedrijven.nl/shiny/mic-per-treatment/. In the combined treatment groups, the triangulated MIC values were lower for nonsurgical treatment than for surgical treatment (p < 0.001). The MICs for nonsurgical treatment can be approximated to be one-ninth (IQR 0.08 to 0.13) of the scale (approximately 11 on a 100-point instrument), and surgical treatment had MICs that were approximately one-fifth (IQR 0.14 to 0.24) of the scale (approximately 19 on a 100-point instrument).

CONCLUSION

MICs vary between condition-treatment combinations and differ depending on the invasiveness of the intervention. Patients receiving a more invasive treatment have higher treatment expectations, may experience more discomfort from their treatment, or may feel that the investment of undergoing a more invasive treatment should yield greater improvement, leading to a different perception of what constitutes a beneficial treatment effect.

CLINICAL RELEVANCE

Our findings indicate that the MIC is context-specific and may be misleading if applied inappropriately. Implementation of these condition-specific and treatment-specific MICs in clinical research allows for a better study design and to achieve more accurate treatment evaluations. Consequently, this could aid clinicians in better informing patients about the expected treatment results and facilitate shared decision-making in clinical practice. Future studies may focus on adaptive techniques to achieve individualized MICs, which may ultimately aid clinicians in selecting the optimal treatment for individual patients.

Postoperative Rehabilitation Protocol Following Arthroscopic Rotator Cuff Repair: A Prospective Single-Arm Pragmatic Interventional Study

Background and Objectives: Rotator cuff tear is the most common cause of shoulder pain. If nonsurgical treatment fails, arthroscopic rotator cuff repair (ARCR) is recommended. Since the standards for rehabilitation after ARCR are not clear, various rehabilitation methods have been suggested. This study intends to investigate the effect on the recovery phase of ARCR patients through a postoperative rehabilitation protocol (PRP) that considers the healing process and rehabilitation trend. Materials and Methods: This single-arm, pragmatic intervention study was conducted on 30 patients, two weeks postoperative day (POD) after ARCR. ARCR patients received intervention for six weeks from POD two-week, and pain intensity and shoulder function were evaluated at two-week intervals until POD 12-week, and range of motion (ROM) was evaluated at POD four-week and eight-week. Results: In this study, all variables improved over time (p < 0.05). As a result of the comparison between time points, a significant improvement was found in shoulder function at POD 6-week. In addition, the effect size had a large effect on ROM (flexion, scaption flexion, abduction, and external rotation) and shoulder function. Conclusions: Management through the PRP based on scientific evidence in the strategy of postoperative rehabilitation of patients with ARCR is effective for pain intensity, ROM, and shoulder function.

LongHest project: A prospective, observational study of extended half-life treatment in the musculoskeletal health of patients with severe haemophilia A

Background

Prophylactic treatment is the gold standard in the treatment of patients with haemophilia. Prophylaxis with extended half‐life (EHL) treatment has shown long‐term safety and efficacy in patients with haemophilia.

Aim

To evaluate the efficacy of prophylaxis with EHL treatment in the frequency of haemarthrosis and musculoskeletal health in adult patients with severe haemophilia A.

Methods

Prospective cohort study. Forty‐six patients with severe haemophilia A were recruited. The frequency of haemarthrosis (self‐reports), joint condition (Haemophilia Joint Health Score), pain intensity (visual analogue scale), range of motion (goniometry), and strength (dynamometry) and muscle activation (surface electromyography) were evaluated. Three assessments were carried out: at baseline (T0), at 6 months (T1) and at 12 months following treatment (T2).

Results

There were significant changes in the within‐subject effect in the frequency of haemarthrosis in elbow (F(1.05;96.20) = 3.95; P < .001) and knee (F(1.73;157.99) = 9.96; P < .001). Significant within‐subject effect in elbow pain intensity (F(2;182) = 63.51; P < .001) was found. The mean values of the frequency haemarthrosis in elbow (from .66±1.01 to .04±.20) and knees (from .55±.68 to .33±.53) decrease after the period study. The intensity of elbow pain and (from 3.08±1.69 to 2.67±1.73), decrease after the 12‐month follow‐up period.

Conclusions

Prophylaxis with extended half‐life treatment reduces the frequency of haemarthrosis in elbow and knee in adult patients with haemophilia. EHL treatment reduces the intensity of elbow pain in patients with haemophilic arthropathy.

Minimal important difference and patient acceptable symptom state for the Numerical Rating Scale (NRS) for pain and the Patient-Rated Wrist/Hand Evaluation (PRWHE) for patients with osteoarthritis at the base of thumb

Background

The Numerical Rating Scale (NRS) and Patient-rated wrist/hand evaluation (PRWHE) are patient-reported outcomes frequently used for evaluating pain and function of the wrist and hand. The aim of this study was to determine thresholds for minimal important difference (MID) and patient acceptable symptom state (PASS) for NRS pain and PRWHE instruments in patients with base of thumb osteoarthritis.

Methods

Fifty-two patients with symptomatic base of thumb osteoarthritis wore a splint for six weeks before undergoing trapeziectomy. NRS pain (0 to 10) and PRWHE (0 to 100) were collected at the time of recruitment (baseline), after splint immobilization prior to surgery, and at 3, 6, 9 and 12 months after surgery. Four anchor-based methods were used to determine MID for NRS pain and PRWHE: the receiver operating characteristics (ROC) curve, the mean difference of change (MDC), the mean change (MC) and the predictive modelling methods. Two approaches were used to determine PASS for NRS pain and PRWHE: the 75^th percentile and the ROC curve methods. The anchor question for MID was the change perceived by the patient compared with baseline; the anchor question for PASS was whether the patient would be satisfied if the condition were to stay similar. The correlation between the transition anchor at baseline and the outcome at all time points combined was calculated using the Spearman’s rho analysis.

Results

The MID for NRS pain was 2.5 using the ROC curve method, 2.0 using the MDC method, 2.8 using the MC method, and 2.5 using the predictive modelling method. The corresponding MIDs for PRWHE were 22, 24, 10, and 20. The PASS values for NRS pain and PRWHE were 2.5 and 30 using the ROC curve method, and 2.0 and 22 using the 75th percentile method, respectively. The area under curve (AUC) analyses showed excellent discrimination for all measures.

Conclusion

We found credible MID estimates for NRS and PRWHE (including its subscales), although the MID estimates varied depending on the method used. The estimates were 20-30% of the range of scores of the instruments. The cut-offs for MID and PASS showed good or excellent discrimination, lending support for their use in future studies.

Clinical outcomes one year after a digital musculoskeletal (MSK) program: an observational, longitudinal study with nonparticipant comparison group

Background

The evidence base for the impact of digital health on musculoskeletal (MSK) outcomes is growing, but it is unclear how much digital MSK programs address pain and function in the intermediate and long term.

Methods

This observational study of digital MSK program participants versus nonparticipants (n = 2570) examined pain, function, depression, and anxiety at 3, 6, and 12 months, and health care use at 12 months. The intervention group engaged in a digital MSK program that included exercise, education, and coaching for at least 3 months. The nonparticipant group registered, but never started the program. We collected data in app or by emailed survey at 3, 6, and 12 months after registering for the program. We conducted descriptive analyses and unadjusted and adjusted regression modeling.

Results

The odds ratio of achieving a minimally clinically important difference (MCID) in pain improvement for the intervention versus the nonparticipant group was 1.97 (95% CI: 1.28, 3.02; p = .002) at 3 months, 1.44 (95% CI: 0.91, 2.25; p = .11) at 6 months, and 2.06 (95% CI: 1.38, 3.08; p = .004) at 12 months in adjusted models. The odds ratio of achieving a MCID in functional improvement for the intervention versus the nonparticipant group was 1.56 (95% CI: 1.03, 2.38; p = .01) at 3 months, 1.55 (95% CI: 1.02, 2.37; p = .04) at 6 months, and 1.35 (95% CI: 0.89, 2.06, p = 0.16) at 12 months in adjusted models. For those with moderate to severe depression or anxiety at baseline, we observed statistically significant lower odds of moderate to severe depression or anxiety at 3 months, 6 months, and 12 months for the intervention versus the nonparticipant group in adjusted models (p < .05). At 12 months, the percentage with invasive, imaging, and conservative services was higher for the nonparticipant versus intervention group by 5.7, 8.1, and 16.7 percentage points, respectively (p < 0.05).

Conclusions

A digital MSK program may offer participants sustained improvement in pain, depression, and anxiety with concomitant decreases in health care use.

Amputee, clinician, and regulator perspectives on current and prospective upper extremity prosthetic technologies

Existing prosthetic technologies for people with upper limb amputation are being adopted at moderate rates. Once fitted for these devices, many upper limb amputees report not using them regularly or at all. The primary aim of this study was to solicit feedback about prosthetic technology and important device design criteria from amputees, clinicians, and device regulators. We compare these perspectives to identify common or divergent priorities. Twenty-one adults with upper limb loss, 35 clinicians, and 3 regulators completed a survey on existing prosthetic technologies and a conceptual sensorimotor prosthesis driven by implanted myoelectric electrodes with sensory feedback via spinal root stimulation. The survey included questions from the Trinity Amputation and Prosthesis Experience Scale, the Disabilities of the Arm, Shoulder, and Hand, and novel questions about technology acceptance and neuroprosthetic design. User and clinician ratings of satisfaction with existing devices were similar. Amputees were most accepting of the proposed sensorimotor prosthesis (75.5% vs clinicians(68.8%), regulators(67.8%)). Stakeholders valued user-centered outcomes like individualized task goals, improved quality of life, device reliability, and user safety; regulators emphasized these last two. The results of this study provide insight into amputee, clinician, and regulator priorities to inform future upper-limb prosthetic design and clinical trial protocol development.

Reliability, minimum detectable change, and minimum clinically important difference of the balance subtest of the Bruininks-Oseretsky test of motor proficiency-second edition in children with cerebral palsy

PURPOSE

This study aimed to investigate the internal consistency, inter-rater, and test-retest reliability of the balance subtest of the Bruininks-Oseretsky test of motor proficiency-second edition (BOT-2) and to estimate the minimum detectable change (MDC) and minimum clinically important difference (MCID) of the balance subtest of the BOT-2 in children with cerebral palsy (CP).

METHODS

In total, 20 children with CP participated in the present study. Internal consistency, test-retest, and inter-rater reliability were computed to establish reliability of the balance subtest of the BOT-2. The MDC95 was estimated from the standard error of measurement (SEM) to determine a real change for an individual child with CP. The anchor- and distribution-based MCID were calculated to determine the smallest change that might be important to clinicians. For concurrent validity, the correlation between the balance subtest of the BOT-2 and the pediatric balance scale (PBS) were calculated using Spearman's correlation.

RESULTS

Internal consistency was good (Cronbach's alpha coefficient = 0.89). The BOT-2 had excellent test-retest (ICC = 0.99, p < 0.001) and inter-rater reliability (ICC = 0.99, p < 0.001). The balance subtest of the BOT-2 had an SEM of 0.70, MDC95 of 9.61, and MCIDs of 2.54 (anchor-based) and 1.38 (distribution-based). Additionally, there was a moderate positive correlation between the balance subtest of the BOT-2 and the PBS (Spearman's rho = 0.629, p = 0.003).

CONCLUSIONS

Our experimental results indicate that the balance subtest of the BOT-2 had good internal consistency, along with excellent test-retest and inter-rater reliability. The change in scores of an individual child with CP should attain 9.61 points on the balance subtest of the BOT-2 to indicate a clinically important change. The MDC95 and MCID values could be helpful in understanding therapeutic effects and evaluating balancing ability using the balance subtest of the BOT-2 in children with CP.

Patients with isolated unstable distal radius fractures, stabilized with volar angular stable locking plate.

INTERVENTIONS

The immediate mobilization group received a removable forearm splint for one week and active supervised group physiotherapy and home exercises for the shoulder, elbow, wrist, and fingers from the first postoperative day. The cast immobilization group received a non-removable cast for five weeks. In the first five weeks supervised group physiotherapy and home exercises were performed for shoulder, elbow, and fingers. Thereafter additional supervised and home exercises for the wrist were started.

MAIN MEASURES

At regular intervals of six and nine weeks, three and six months, and one year post surgery range of motion, grip strength, and x-rays were evaluated. Additionally, the shortened disabilities of the arm, shoulder and hand (QuickDASH) score, Patient-rated Wrist Evaluation, Mayo Wrist score, and pain according to the Visual Analog Scale score were analyzed.

RESULTS

One hundred and sixteen patients were prospectively randomized into two study groups. At the one-year follow-up, patients in the immediate mobilization group showed a significantly higher range of motion in extension/flexion (mean difference 10.2°, 99% confidence interval 0.6-19.8), grip strength (mean difference 5.1 kg, 99% confidence interval -0.5 to 10.7), and Mayo Wrist score (mean difference 7.9 points, 99% confidence interval 2.3-13.5) than the cast immobilization group. Range of motion in supination/pronation (mean difference 13.4°, 99% confidence interval 1.5-25.3) and in radial/ulnar deviation (mean difference 6.3°, 99% confidence interval 0.9-11.7) differed significantly up to nine weeks favoring the immediate mobilization group. The Patient-rated Wrist Evaluation revealed significantly better scores after three months (mean difference 9.3 points, 99% confidence interval 0.5-18.1) and QuickDASH after six months (mean difference 7.3 points, 99% confidence interval 0.3-14.3) in the immediate mobilization group. All other subsequent follow-up examinations indicated no significant differences in respect of pain, range of motion, and patient-reported outcome measurements between the study groups. There were no significant differences in respect of radiological loss of reduction and complications between the groups.

CONCLUSIONS

Immediate mobilization in combination with supervised physiotherapy of the wrist after volar locking plate fixation of unstable distal radius fractures results in a significantly improved range of motion and grip strength after one year compared to cast immobilization. No increased risk for loss of reduction and other complications was observed.

Midterm Patient-Reported Outcomes in Wrist Denervation for Post-Traumatic Arthritis

PURPOSE

To analyze patient-reported outcomes and range of motion in a cohort of patients who underwent wrist denervation for advanced wrist osteoarthritis. We hypothesized that improvements in pain and function would be seen with preserved range of motion.

METHODS

Thirty patients underwent wrist denervation for symptomatic stage 1-4 scapholunate advanced collapse (SLAC) arthritis. Patient-Rated Wrist Evaluation, Quick Disabilities of the Arm, Shoulder, and Hand score, and range of motion measurements were assessed preoperatively and at final follow-up.

RESULTS

The mean follow-up duration was 47 months (range, 24-92 months). The mean age at surgery was 65 years, and 96% of the patients were men. The dominant hand was involved in 66% of cases. The SLAC grades of patients involved were as follows: 10% (n = 3) grade 1, 27% (n = 8) grade 2, 60% (n = 18) grade 3, and 3% (n = 1) grade 4. Two patients required conversion to a wrist fusion and were considered failures. In the remaining 28 patients, the mean Patient-Rated Wrist Evaluation total score decreased 22 points (82.4 to 60.9) and the mean Quick Disabilities of the Arm, Shoulder, and Hand score decreased 8 points (32.4 to 24.8). Total arc of wrist flexion-extension showed an average 5° improvement.

CONCLUSIONS

This method of wrist denervation was a viable salvage option for patients with symptomatic SLAC wrist osteoarthritis to preserve motion, decrease pain, and increase function with a low absolute failure rate at mid- to long-term follow-up.

Measurement properties of the box and block test in children with unilateral cerebral palsy

This study aimed to examine the reliabilities (test-retest reliability and measurement error), construct validity, and the interpretability (minimal clinically important difference) of the Box and Block Test (BBT) to interpret test scores precisely for children with UCP. A total of 100 children with UCP were recruited and 50 children from the whole sample assessed the BBT twice within 2-week interval. The BBT, the Melbourne Assessment 2, the Bruininks-Oseretsky Test of Motor Proficiency, 2nd Edition, and the Pediatric Motor Activity Log Revised were measured before and immediately after a 36-h intensive neurorehabilitation intervention. Measurement properties of the BBT were performed according to the COnsensus-based Standards for the selection of health Measurement INstruments checklist. The test-retest reliability of the BBT was high (intraclass correlation coefficient = 0.98). The measurement error estimated by the MDC₉₅ value was 5.95. Construct validity was considered good that 4 of 4 (100%) hypotheses were confirmed. The interpretability estimated by the MCID ranged from 5.29 to 6.46. The BBT is a reliable and valid tool for children with UCP. For research and clinical applications, an improvement of seven blocks on the BBT is recommended as an indicator of statistically significant and clinically important change.

The Effects of Auditory Feedback Gait Training Using Smart Insole on Stroke Patients

This study aimed to assess the effect of the auditory feedback gait training (AFGT) using smart insole on the gait variables, dynamic balance, and activities of daily living (ADL) of stroke patients. In this case, 45 chronic stroke patients who were diagnosed with a stroke before 6 months and could walk more than 10 m were included in this study. Participants were randomly allocated to the smart insole training group (n = 23), in which the AFGT system was used, or to the general gait training group (GGTG) (n = 22). Both groups completed conventional rehabilitation, including conventional physiotherapy and gait training, lasting 60 min per session, five times per week for 4 weeks. Instead of gait training, the smart insole training group received smart insole training twice per week for 4 weeks. Participants were assessed using the GAITRite for gait variables and Timed Up and Go test (TUG), Berg Balance Scale (BBS) for dynamic balance, and Modified Barthel Index (MBI) for ADL. The spatiotemporal gait parameters, symmetry of gait, TUG, BBS, and MBI in the smart insole training group were significantly improved compared to those in the GGTG (p < 0.05). The AFGT system approach is a helpful method for improving gait variables, dynamic balance, and ADL in chronic stroke patients.

PROMIS scores of patients undergoing neoadjuvant and adjuvant radiation therapy for surgically excised soft tissue sarcoma

•

First to evaluate PROMIS for patients undergoing radiotherapy and surgery for sarcoma.

•

Patients exhibited meaningful change in PROMIS scores throughout the treatment.

•

Analyses show PROMIS scores were similar between pre- and post-operative radiotherapy.

•

Wound complications were associated with increases in anxiety and decreases in function.

•

These data should be considered when selecting ideal therapy.

Introduction

Few recent studies have examined patient reported outcomes (PROs) during pre- or post-operative radiation therapy (RT) for soft tissue sarcoma (STS), and none have used PROMIS. This study aims to examine PROMIS scores across peri-operative time points for patients receiving pre- or post-operative RT.

Methods

Anxiety, depression, pain interference, and physical function PROMIS domains were collected at the pre-operative (1), immediate post-operative (2), and post-treatment completion (3) timepoints for patients undergoing surgery and either pre-operative or post-operative RT. Median scores were compared between groups using the Kruskal-Wallis test. The reliable change index was used to determine minimum important change in PROMIS scores and to compare scores between timepoints.

Results

95 patients were included (19 pre-operative, 76 post-operative). Both groups had significant decreases in function during treatment. Patients with wound complications were more likely to have significant increases in anxiety (36.4% vs. 8.3%; p = 0.020) and decreases in physical function (57.1% vs. 16.2%; p = 0.011) independent of RT timing.

Conclusions

This study demonstrates minimum significant change thresholds to detect PROMIS changes in STS patients undergoing pre- and post-operative radiotherapy. As expected, more patients with pre-operative RT than post-operative RT had wound complications (p = 0.06), but patients with complications in both groups had worse anxiety and function at the completion of treatment compared with those that did not. The association of wound complications with worse anxiety and physical function at completion of treatment should be considered when making individualized treatment recommendations regarding the timing of RT.

Early Outcomes of Scapholunate Injuries With Concomitant Distal Radius Fractures

Background: There is limited literature regarding the treatment of concomitant scapholunate ligament (SL) injuries in acute distal radius fractures (DRFs). We hypothesized that surgical treatment of SL injuries in adult patients with DRFs leads to improved functional outcomes. Methods: A retrospective review was made of 42 adult patients who underwent surgical treatment of a DRF with a SL injury between 2005 and 2013. In all, 39 of the 42 patients sustained an intra-articular DRF (AO B or C). SL injury was diagnosed by SL diastasis > 3 mm on posteroanterior (PA) radiographs, magnetic resonance imaging, or with wrist arthroscopy. Patients were divided into 3 groups: 23 had a SL repair and were treated within 21 days of injury (acute), 8 underwent SL repair greater than 21 days from injury (subacute/chronic), and 11 did not undergo repair (non-operative). Median overall time to clinical follow-up was 5.1 years. Mayo Wrist Scores (MWS) and Disabilities of the Arm, Shoulder and Hand (DASH) scores were used to evaluate functional outcome. Results: Clinical outcomes measured by the MWS at final follow-up (6 months-12 years) showed no significant differences between the 3 groups. Of patients treated acutely, 17.3% had good to excellent MWS. MWS at 1-year follow-up was 68.4, 70, and 64 in the acute, subacute/chronic, and non-operative groups, respectively. DASH scores were 16.7, 14.3, and 11.8 in the acute, subacute/chronic, and nonoperative groups, respectively, at a mean of 7.8 years. Conclusions: At mid-term follow-up, all 3 treatment groups had similar DASH scores to the general population. There were no statistical functional differences between any of the groups based upon MWS or DASH scores.

The critical difference in the DASH (Disabilities of the Arm, Shoulder, and Hand) outcome measure after essential upper extremity tumor surgery

BACKGROUND

The DASH (Disabilities of the Arm, Shoulder, and Hand) is a scored questionnaire that is widely used to evaluate the health-related quality of life of patients with upper limb musculoskeletal disorders. However, numerical changes in the measure scores lack clinical significance without meaningful threshold change values of outcome measures that are diagnostically specific. The minimal clinically important difference (MCID) is useful for the interpretation of scores by defining the smallest change that a patient would perceive. However, the MCIDs of the scores in orthopedic oncology patients has not been reported. We aimed to determine the MCIDs of the measure in orthopedic oncology patients.

METHODS

Data from our health-related quality of life database from 1999 to 2005 were retrospectively reviewed after institutional review board approval. Seventy-eight patients who underwent surgery and completed 2 surveys during postoperative follow-up were evaluated. Two different methods were used to estimate the MCIDs: distribution-based and anchor-based approaches (the latter used receiver operating characteristic analysis).

RESULTS

Using distribution-based methods, the MCIDs of the DASH questionnaire were 7.4 and 8.3 by half standard deviation and the 90% interval of minimal detectable change, respectively. By anchor-based method (receiver operating characteristic analysis), the MCID was 8.3.

CONCLUSION

The MCID values calculated by each method validates that the results for upper extremity oncology patients were similar to those reported in other orthopedic conditions. These results identify the threshold for meaningful improvements in DASH scores in orthopedic oncology patients and establish the reference to evaluate health-related quality of life and the outcomes of upper extremity oncology surgery. These data should be further refined for disease- and reconstruction-specific analyses.

Assessment of construct validity of the Finnish versions of the Disabilities of Arm, Shoulder and Hand Instrument and the Michigan Hand Outcomes Questionnaire

STUDY DESIGN

Cross-sectional study.

INTRODUCTION

There is a lack of information on the measurement properties of patient-reported upper extremity instruments and their association to health-related quality of life (HRQoL).

PURPOSE OF THE STUDY

This study aimed to examine and compare the measurement properties and construct validity of the Disabilities of Arm, Shoulder, and Hand (DASH) Instrument and the Michigan Hand Questionnaire (MHQ) using a heterogeneous sample of patients with hand and wrist problems.

METHODS

Two hundred fifty consecutive patients visiting a general orthopedic outpatient clinic due to various hand/wrist problems were invited to participate in the study. A total of 193 (77%) participants provided sufficient patient-reported outcome data and were included in the analysis. Participants completed the DASH, the MHQ, the EQ-5D-3L, and pain on a visual analog scale instruments. Grip and key pinch forces were measured. Scale targeting, relatedness of demographics, and construct validity of the DASH and the MHQ were assessed.

RESULTS

Both the DASH and the MHQ had good targeting, but the DASH had wider coverage. The convergence between the DASH and the MHQ was high. The DASH was more closely related to HRQoL than the MHQ in terms of EQ-5D scores.

DISCUSSION

The DASH instrument appeared to measure hand function and disability from a perspective of HRQoL superior to the MHQ among patients with heterogeneous hand and wrist complaints.

CONCLUSION

The DASH performs well in measuring the HRQoL-related hand outcomes while the MHQ might be more specific for the affected hand.

A reliability study of a novel visual ischemic palpation scale in an experimental setting

BACKGROUND

Manual palpation is an important part of the clinical examination and generally it has low reliability. The aim of this study was to assess the reliability of a novel method for discriminating 3 different levels of palpation force.

METHODS

This reliability study included 96 healthy physiotherapists and physiotherapy students, who have been taught a new palpation graduated procedure called Visual Ischemic Palpatory Scale (VIPS), aimed to classify the applied pressure based on the finger's ischemia. Force was recorded by a force measurement system putting sensor over a rigid surface. To study the characteristic of VIPS the analysis of variance (ANOVA), Spearman rank correlation coefficient, Intraclass Correlation Coefficient (ICC), Standard Error of Measurements (SEM), and Minimal Detectable Change (MDC) were calculated.

RESULTS

Three distinct degrees were found with distinct forces expression: 1st degree 76.04 g (95% CI 65.86-86.22), 2nd degree 307.87 g (95% CI 263.29-352.44) and 3rd degree 1319.48 g (CI 1204.73-1434.23). Male participants significantly recorded a greater force than females. Good to excellent reliability across degrees were found (0.89 [95% CI: 0.82-0.97]), and final agreement found that more than 65.6% of sample recorded a force in the cut-offs identified. SEM values became bigger as the recorded force increased and MDC were equal to 48.94 g, 188.73 g, and 379.24 g for 1st, 2nd, and 3rd degree, respectively.

CONCLUSIONS

VIPS would appear to have three distinct degrees, sex dependent, with specific force expression for each degree and a good to excellent intra-rater reliability, but a poor agreement between raters.

Designing and Psychometric Properties of Appraisal Adherence to Care and Treatment Scale in Liver Transplantation Recipients

Background: Care and treatment adherence are important factors for given good liver transplantation outcomes. Objectives: Design and validate an instrument to appraise adherence to care and treatment in liver transplantation recipients. Methods: A mixed-methods sequential exploratory study was conducted in two phases from 2017 to 2019, in the Liver Transplantation Clinic Tehran, Iran. In the qualitative phase, the concept of care and treatment adherence in liver transplantation recipients extracted by a conventional content analysis was performed on semi-structural interviews that were conducted on 18 liver transplantation recipients that were recruited through purposive sampling technique. Also, two physicians, one nurse coordinator of the liver transplantation team, and two family members were interviewed. The scale was developed based on operational definitions extracted from the qualitative phase. The validity was assessed by face, content, construct validity, and confirmatory factor analysis. The reliability was also evaluated by calculating test-retest intraclass correlation coefficient and Cronbach's alpha. The exploratory factor analysis was carried out with 286 filled the questionnaire. Results: Four factors were extracted in factor analysis. These factors explained 45.622% of the variance. The final version of the scale consisted of 20 items. The Cronbach's alpha coefficient reported as 0.889 for the total scale and the intraclass correlation coefficient was reported as 0.912. The confirmatory factor analysis led to a fitting model. Chi-square indices were reported as CMIN/DF = 2.34, NFI = 0.94, CFI = 0.96, and RAMSEA = 0.067. Conclusions: With a four factors structure, validity and reliability of adherence to care and treatment scale are acceptable; therefore, it can be used for appraisal care and treatment adherence in liver transplant recipients.

Comparison of low level and high power laser combined with kinesiology taping on shoulder function and musculoskeletal sonography parameters in subacromial impingement syndrome: a Randomized placebo-controlled trial

Background: Subacromial impingement syndrome (SAIS) is a common cause of shoulder pain. The effects of physiotherapy modalities including low-level laser (LLL) and high power laser (HPL) on the SAIS have mostly been evaluated by the subjective outcome variables accompanied with the controversial findings and none of them has compared a combination of these two modalities, yet.Objectives: The present study was conducted to evaluate the effects of low-level laser (LLL) and high power laser (HPL) combined with kinesiology taping (KT), on the pain, function, and musculoskeletal ultrasound (MSKUS) parameters in the SAIS.Methods: Thirty patients with SAIS were randomly divided into the LLL-KT, HPL-KT, and sham-KT groups, respectively. Patients received seven treatment sessions. Visual analogue scale (VAS), shoulder pain and disability index (SPADI), MSKUS parameters were measured before and 48 hours after the treatment cessation.Results: Pain intensity significantly reduced in the LLL-KT (-2.43 (0.97)), HPL-KT (-3.43 (1.99)), and sham-KT (-2.43 (1.62)) (P < .01). All the SPADI subscales are significantly reduced in all the groups (P < .05), except for the pain in the sham-KT (P = .06). Significant improvements were only observed in the diameters of biceps (P < .05), supraspinatus tendon thickness in short and long axes (P < .05), occupation ratio (P = .004), and echogenicity (P = .03) in the HPL-KT. Although the acromiohumoral distance (AHD) significantly increased in all the groups including the sham-KT (P < .01), supraspinatus tendon thickness significantly decreased (P < .05), and echogenicity increased (P = .003) just in the HPL-KT.Conclusions: Kinesiology taping method alone is an effective intervention. Nevertheless, adding the analgesic and anti-inflammatory effects of both LLL and HPL to KT seems to result in better improvement of the pain, function, and MSKUS parameters in the SAIS. Findings of this study suggested that the HPL is more beneficial than the LLL or KT alone for management of the patients with SAIS.

Nonoperative treatment of chronic, massive irreparable rotator cuff tears: a systematic review with synthesis of a standardized rehabilitation protocol

PURPOSE

A massive, irreparable rotator cuff tear may cause significant pain and dysfunction. However, the efficacy of nonoperative treatment modalities in this subset of patients is not currently well known. Also, there is currently no gold standard nonoperative protocol to guide treatment. The goal of the present systematic review is to determine if there is any evidence to support the use of various nonoperative treatment modalities and synthesize a standardized nonoperative treatment protocol for the patient with a massive irreparable rotator cuff tear.

METHODS

A comprehensive review of the literature utilizing PRISMA guidelines was performed. Studies involving clinical outcomes of nonoperative treatment of massive, irreparable rotator cuff tears were included. Articles were reviewed by 2 reviewers to determine inclusion or exclusion based on established criteria. Selected articles were reviewed for results of clinical and functional outcomes. The studies were also reviewed to determine their level of evidence and potential sources of bias. A standardized nonoperative treatment protocol was developed by taking described elements of the protocols used in studies that demonstrated clinical improvement beyond the MCID for the outcome scores used by the authors.

RESULTS

A total of 10 studies met inclusion criteria for our studies. Of the included studies, 1 was Level III evidence and the remaining 9 were Level IV evidence. Multiple studies showed significant improvement exceeding the MCID for functional outcome scores following treatment. Also, several studies demonstrated significant improvements in strength and range of motion. The overall success of nonoperative treatment ranged from 32%-96%. The synthesized nonoperative treatment protocol is characterized by requiring some supervised physical therapy, often requiring 12 weeks or more, focusing on supine exercises with gradual progression to upright. Corticosteroid injections and nonsteroidal anti-inflammatory drugs may also be of benefit.

CONCLUSION

Despite low-quality evidence, nonoperative treatment has been shown to be efficacious for patients with chronic, massive, irreparable rotator cuff tears. Using these results, a synthesized rehabilitation program was developed to guide clinicians when treating patients with massive irreparable rotator cuff tears.

Effects of myofascial release on frequency of joint bleedings, joint status, and joint pain in patients with hemophilic elbow arthropathy: A randomized, single-blind clinical trial

BACKGROUND

Chronic joint injury of the elbow joint is common in patients with hemophilia. Myofascial release is used for the management of pain and functionality in patients with chronic restrictions.

OBJECTIVE

To evaluate the effectiveness of myofascial release in patients with hemophilic elbow arthropathy.

METHODS

Sixty-nine patients with hemophilia took part in this randomized controlled trial. They were recruited from 10 hemophilia patient Associations. They were randomly allocated to experimental (n = 35) or control group (n = 34). The intervention consisted of three 50-min sessions of fascial therapy over a 3-week period. The intervention included 11 bilaterally administered maneuvers in both upper limbs (from shoulder girdle to forearm). The study variables were frequency of elbow bleeding (self-report), joint status (Hemophilia Joint Health Score), and joint pain (visual analog scale) at baseline, after the intervention, and at the 3-month follow-up.

RESULTS

There were significant changes (P < .001) in the repeated measures factor in the frequency of hemarthrosis (F = 20.64), joint status (F = 31.45), and perceived joint pain (F = 30.08). We found group interaction with the (P < .001) in the frequency of hemarthrosis (F = 21.57), joint status (F = 99.98), and perceived joint pain (F = 44.26). There were changes (P < .01) in the pairwise comparison analysis between the pretreatment assessment and the posttreatment and follow-up assessments.

CONCLUSIONS

Myofascial release decreases frequency of elbow bleedings, and improved joint status and perception of elbow pain in patients with hemophilic elbow arthropathy. Myofascial release may be recommended to improve joint status and joint pain in patients with hemophilic elbow arthropathy.

Multifactorial Wrist Pain Treated with Tenotomy of Anomalous Flexor Carpi Radialis Brevis: A Case Report

CASE

We present a case of a 33-year-old left hand-dominant/right hand-involved active duty Navy sailor woman with volar radial wrist pain. She underwent scaphoid cyst excision and bone grafting as well as tenotomy. Intraoperatively, she was noted to have a flexor carpi radialis brevis (FCRB) tendon that was transected. After surgery, her 1-year outcomes demonstrated range of motion improved equivalent with her contralateral side, her visual analogue scale (VAS) pain score had decreased to 1, and her QuickDASH and Patient-Rated Wrist Evaluation improved.

CONCLUSIONS

Our case represents 1-year outcome after surgical release of a FCRB. Our patient's pain and functional scores exceeded the minimal clinically important difference.

Reliability, standard error of measurement, and minimal detectable change of the star excursion balance test in children with cerebral palsy

OBJECTIVE

The present study aimed to estimate the reliability, standard error of measurement (SEM), and minimum detectable change (MDC) of the star excursion balance test (SEBT) in children with cerebral palsy (CP).

METHODS

Eight children with CP (five boys and three girls, sixteen legs) participated in this study. Each child carried out the SEBT and was assessed by two examiners. To determine intra-rater reliability, the intra-class correlation coefficient (ICC) model (3, 3) was calculated. To determine the inter-rater reliability, the ICC model (2, 3) was computed.

RESULTS

In terms of the intra-rater reliability of the SEBT, the ICC varied from 0.98 to 0.99 and the total ICC score was 0.99 (p< 0.001). For the inter-rater reliability, the ICC varied from 0.98 to 1.00 and the total ICC score was 0.99 (p< 0.001). The SEBT had an SEM of 2.63 and an MDC of 7.31.

CONCLUSION

The SEBT is not only reliable with a small SEM, but is also a simple and cheap assessment of dynamic balance in children with CP.

Bodily pain in survivors of acute respiratory distress syndrome: A 1-year longitudinal follow-up study

PURPOSE

Acute respiratory distress syndrome (ARDS) survivors frequently experience bodily pain during recovery after the intensive care unit. Longitudinal course, risk factors and associations with physical and neuropsychological health is lacking.

METHODS

We collected self-reported pain using the Short Form-36 Bodily Pain (SF-36 BP) scale, normalized for sex and age (range: 0-100; higher score = less pain), along with physical and mental health measures in a multi-center, prospective cohort of 826 ARDS survivors at 6- and 12-month follow-up. We examined baseline and ICU variables' associations with pain via separate unadjusted regression models.

RESULTS

Pain prevalence (SF-36 BP ≤40) was 45% and 42% at 6 and 12 months, respectively. Among 706 patients with both 6- and 12-month data, 34% reported pain at both timepoints. Pre-ARDS employment was associated with less pain at 6-months (mean difference (standard error), 5.7 (0.9), p < 0.001) and 12-months (6.3 (0.9), p < 0.001); smoking history was associated with greater pain (-5.0 (0.9), p < 0.001, and - 5.4 (1.0), p < 0.001, respectively). In-ICU opioid use was associated with greater pain (-6.3 (2.7), p = 0.02, and - 7.3 (2.8), p = 0.01, respectively). At 6 months, 174 (22%) patients reported co-occurring pain, depression and anxiety, and 227 (33%) reported co-occurring pain and impaired physical function.

CONCLUSION

Nearly half of ARDS survivors reported bodily pain at 6- and 12-month follow-up; one-third reported pain at both time points. Pre-ARDS unemployment, smoking history, and in-ICU opioid use may identify patients who report greater pain during recovery. Given its frequent co-occurrence, clinicians should manage both physical and neuropsychological issues when pain is reported.

Effect of a novel stretching technique on shoulder range of motion in overhead athletes with glenohumeral internal rotation deficits: a randomized controlled trial

Background

The cross-body and the modified sleeper stretch have been used to improve posterior shoulder soft tissue flexibility and to increase glenohumeral joint internal rotation (GHJ IR) in overhead athletes. However, due to the inability to stabilize patient’s scapula and control GHJ rotation with the cross-body stretch and the potential for subacromial impingement or symptoms’ aggravation with the modified sleeper stretch, a new stretching technique (Passive Glenohumeral Internal Rotation with Clam Shell Bridging) was developed as an alternative to these commonly used stretches that may allow for greater stability of the scapula without reproducing symptoms. Thus, the current study aimed to examine and compare a novel stretching technique to the traditional modified sleeper stretch to determine the effect on glenohumeral IR range of motion (ROM) and self-reported pain in overhead athletes with glenohumeral internal rotation deficits (GIRD).

Methods

Forty-two overhead athletes with GIRD [mean age 25.9 ± 2.6 years, 20 males and 22 females] participated in this study. Participants were randomly assigned into either novel stretching group or modified sleeper stretching group. IR ROM was measured with a digital inclinometer before, immediately, and at week 4 post intervention, while pain was measured with Numeric Pain Rating Scale before and at week 4 post intervention.

Results

There was no significant group by time interaction effect for IR ROM (p = 0.27); however, there was a significant change over time (p < 0.001, η² = 0.77). Both groups demonstrated a significant increase in IR from baseline to immediate and week 4, and from immediate to week 4 (p < 0.001). There was a significant group by time interaction for pain intensity (p < 0.001, η² = 0.72). Results showed a significant reduction in pain intensity over time in the novel group (p = 0.001, d = 2.18), but not in the traditional group (p = 0.231, d = 0.46).

Conclusion

Both stretches appear to be effective at improving IR ROM in overhead athletes with GIRD. However, the novel stretching might be more effective at reducing shoulder pain and thus may be more appropriate for symptomatic patients.

Treatment of Breast Cancer-Related Lymphedema Using Negative Pressure Massage: A Pilot Randomized Controlled Trial

OBJECTIVE

To evaluate the efficacy of negative pressure massage treatment (NPMT) compared with manual lymphatic drainage (MLD) in women with chronic breast cancer-related lymphedema (LE). We hypothesized that NPMT would result in greater improvements in LE and upper limb function.

DESIGN

Pilot single-blinded randomized controlled trial.

SETTING

Health sciences university.

PARTICIPANTS

Of 64 women screened, 28 met eligibility requirements (ie, >18y of age; completed active treatment for breast cancer; had unilateral arm LE for ≥1y; were not receiving LE care; had stable LE) and were randomized to the NPMT (n=15) and control groups (n=13).

INTERVENTIONS

The intervention group received NPMT and the control group received MLD; both received twelve 60-minute sessions over 4-6 weeks.

MAIN OUTCOME MEASURES

Bioimpedance (lymphedema index [L-Dex] units]), limb volume (mL) calculated from limb circumference, and Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH) score.

RESULTS

Outcomes were analyzed for 28 women. Compared to the MLD group, the NPMT group demonstrated greater improvement with a large effect size in L-Dex scores (P=.001; standardized mean difference [SMD]=-1.15; 95% confidence interval, -1.96 to -0.35) and interlimb volume differences (P=.038; SMD=-0.83; 95% confidence interval, -1.60 to -0.05). Differences in DASH scores were not statistically significant (P=.067).

CONCLUSIONS

Compared to MLD, treatment with NPMT resulted in greater improvement in L-Dex scores and interlimb volume differences in women with a duration of unilateral upper limb LE of >1 year. Our findings need to be confirmed in a larger randomized controlled trial.

Improving Efficiency of Patient-Reported Outcome Collection: Application of Computerized Adaptive Testing to DASH and QuickDASH Outcome Scores

PURPOSE

Patient-reported outcome measures assess health status and treatment outcomes in orthopedic care, but they may burden patients with lengthy questionnaires. Predictive models using machine learning, known as computerized adaptive testing (CAT), offer a potential solution. This study evaluates the ability of CAT to improve efficiency of the 30-item Disabilities of the Arm, Shoulder, and Hand (DASH) and 11-item QuickDASH questionnaires.

METHODS

A total of 2,860 DASH and 27,355 QuickDASH respondents were included in the analysis. The CAT system was retrospectively applied to each set of patient responses stored on the instrument to calculate a CAT-specific score for all DASH and QuickDASH entries. The accuracy of the CAT scores, viewed in the context of the minimal clinically important difference for both patient-reported outcome measures (DASH, 12; QuickDASH, 9), was determined through descriptive statistics, Pearson correlation coefficient, intraclass correlation coefficient, and distribution of scores and score differences.

RESULTS

The CAT model required an average of 15.3 questions to be answered for the DASH and 5.8 questions for the QuickDASH, representing a 49% and 47% decrease in question burden, respectively. Mean CAT score was the same for DASH and 0.1 points lower for QuickDASH with similar SDs (DASH, 12.9 ± 19.8 vs 12.9 ± 19.9; QuickDASH, 32.7 ± 24.7 vs 32.6 ± 24.6). Pearson coefficients (DASH, 0.99; QuickDASH, 0.98) and intraclass correlation coefficients (DASH, 1.0; QuickDASH, 0.98) indicated strong agreement between scores. The difference between the CAT and full score was less than the minimal clinically important difference in 99% of cases for DASH and approximately 95% of cases for QuickDASH.

CONCLUSIONS

The application of CAT to DASH and QuickDASH surveys demonstrated an ability to lessen the response burden with negligible effect on score integrity.

CLINICAL RELEVANCE

In the case of DASH and QuickDASH, CAT is an appropriate alternative to full questionnaire implementation for patient outcome score collection.

The Efficacy of Tele-Rehabilitation Program for Improving Upper Limb Function among Adults Following Elbow Fractures: A Pilot Study

Background: Active mobilization post-elbow fractures reduces the incidence of complications. Occupational therapists use tele-rehabilitation, incorporating technology into their practices. There is a lack of evidence-based trials regarding the integration of tele-rehabilitation during treatment. We therefore aimed to compare tele-rehabilitation treatment outcomes with conventional rehabilitation in improving the upper limb function post-elbow fractures. Methods: Eighteen participants post-elbow surgery due to fracture were divided into two groups according to age and fracture type. The groups received one month of treatment: the tele-rehabilitation group (N = 9, median age 33.0 ± 27.9 years, range 18.5–61.0) received 1–2 tele-rehabilitation treatments per week via a biofeedback system of elbow motion (the ArmTutor and 3D Tutor systems, MediTouch Ltd., Netanya, Israel) and 1–2 treatments in an outpatient clinic, and the control group (N = 9, median age 60.0 ± 37.0 years, range 20.5–73.0) received 3–4 treatments per week in the clinic. Both groups were instructed to self-practice at home. Four evaluations were performed: before and after the intervention, and 3 months and 1 year from surgery. The outcome measures included the Jebsen–Taylor hand function test; the disabilities of the arm, shoulder, and hand questionnaire; the patient-rated elbow evaluation; satisfaction; passive and active range of motion (ROM); and strength measurements. Results: Findings demonstrated a significant improvement in the ROM and in functional assessments in both groups. No statistically significant differences were found between the groups. The subjects in the tele-rehabilitation group reported a higher level of satisfaction and needed less help from a family member during practice. Conclusions: Tele-rehabilitation programs could be incorporated in the framework of treatment following elbow fractures. Tele-rehabilitation is a cost-effective treatment, suitable for patients with accessibility difficulties or who have difficulty arriving at the clinic.

Effects of 12 Weeks of Progressive Early Active Exercise Therapy After Surgical Rotator Cuff Repair: 12 Weeks and 1-Year Results From the CUT-N-MOVE Randomized Controlled Trial

BACKGROUND

Traumatic full-thickness rotator cuff tears are typically managed surgically, followed by rehabilitation, but the load progression to reach an optimal clinical outcome during postoperative rehabilitation is unknown.

PURPOSE

To evaluate whether there was a superior effect of 12 weeks of progressive active exercise therapy on shoulder function, pain, and quality of life compared with usual care.

STUDY DESIGN

Randomized controlled trial; Level of evidence, 1.

METHODS

Patients with surgically repaired traumatic full-thickness rotator cuff tears were recruited from 2 orthopaedic departments and randomized to progressive active exercise therapy (PR) or limited passive exercise therapy (UC [usual care]). The primary outcome was the change in the Western Ontario Rotator Cuff Index (WORC) score between groups from before surgery to 12 weeks after surgery. Secondary outcomes included changes in the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire score, pain, range of motion, and strength. Adverse events were registered during the intervention period.

RESULTS

A total of 82 patients were randomized to the PR (n = 41) or UC (n = 41) group. All 82 patients (100%) participated in the 12-week assessment and 79 in the 1-year follow-up. At 12 weeks, there was no significant difference between the groups in the change in the WORC score from baseline adjusted for age, sex, and center (physical symptoms: P = .834; sports and recreation: P = .723; work: P = .541; lifestyle: P = .508; emotions: P = .568). Additionally, there was no between-group difference for the secondary outcomes including the WORC score at 1 year and the DASH score, pain, range of motion, and strength at 12 weeks and 1 year. Both groups showed significant improvements over time in all outcomes. In total, there were 13 retears (16%) at 1-year follow-up: 6 in the PR group and 7 in the UC group.

CONCLUSION

PR did not result in superior patient-reported and objective outcomes compared with UC at either short- or long-term follow-up (12 weeks and 1 year).

Validity and reliability of smartphone-based pelvic rotation evaluations of children with cerebral palsy while sitting, standing, and standing on one leg

PURPOSE

We explored the test-retest reliability of pelvic rotation measured using a smartphone and established criterion-related validity by analyzing simple linear regression between pelvic rotation data obtained using the smartphone and those measured by a palpation meter.

METHODS

We recruited 12 children with cerebral palsy (CP) (7 boys and 5 girls) and measured pelvic rotation using a smartphone application and a palpation meter in the sitting, standing, and one-leg standing positions. Test-retest reliability was evaluated by calculating intraclass correlation coefficients (ICCs); simple linear regression was analyzed to explore the relationships between smartphone and palpation meter data.

RESULTS

In terms of the test-retest reliability of pelvic rotation measured by the smartphone, the ICCs ranged from 0.85 to 0.95. A positive linear correlation was found between smartphone and palpation meter data.

CONCLUSIONS

We confirmed that measurement of pelvic rotation using a smartphone was reliable when children with CP were in the sitting, standing, and one-leg standing positions. In addition, pelvic rotation measured using the smartphone correlated significantly with that measured using a palpation meter.

Immediate Effects of Aquatic Therapy on Balance in Older Adults with Upper Limb Dysfunction: An Exploratory Study

Background: Aquatic physiotherapy has been shown to be effective in developing balance, strength, and functional reach over time. When dealing with immediate effects, the literature has concentrated more on the body’s physiological response to the physical and mechanical properties of water during passive immersion. The purpose of this study was to evaluate the effects of a single 45-min active aquatic physiotherapy session on standing balance and strength, and its relationship with functional reach in persons 55 years and older with upper limb dysfunction. Methods: The intervention group (n = 12) was assessed before and after a single aquatic physiotherapy session, while the control group (n = 10) was evaluated before and after 45 min of sitting rest. Functional assessment was made using the visual analogue pain scale (points), step test (repetitions), functional reach test (cm), and global balance-standing test on a force platform (% time). A two-way repeated-measures ANOVA was applied (p < 0.05). Results: The intervention group showed non-significant improvements between measurement before and after the intervention: Pain: 6.2 ± 1.9 vs. 5.2 ± 2.3 cm, steps: 7.0 ± 2.0 vs. 7.4 ± 1.8 repetitions, reach: 9.1 ± 2.8 vs. 10.4 ± 3.8 cm, and balance: 61.7 ± 5.9 vs. 71.3 ± 18.2% time in balance on the platform. The control group showed fewer changes but had better baseline values. A comparison between groups with time showed no significant differences in these changes. Conclusions: No significant immediate effects were found for one session of aquatic physiotherapy applied to patients older than 55 years with upper limb dysfunction.

Efficacy of low-level laser therapy combined with exercise for subacromial impingement syndrome: A randomised controlled trial

OBJECTIVE

To investigate the effect of low-level laser therapy (LLLT) combined with exercise on shoulder pain and disability in patients with subacromial impingement syndrome (SIS).

DESIGN

Randomised controlled trial.

SETTING

Pontifical Catholic University.

SUBJECTS

We enrolled 120 subacromial impingement syndrome patients.

INTERVENTION

Groups I (n = 42), II (n = 42) and III (n = 36) were treated with Low-level laser therapy and exercise, exercise only and Low-level laser therapy only, respectively. Interventions were conducted three times a week for 8 weeks.

MAIN OUTCOME MEASURES

The primary outcome was the change in shoulder pain and disability index (SPADI). Secondary outcomes included changes in the numeric pain rating scale and medication intake.

RESULTS

Average ages of patients in groups I, II and III were 51.9 ± 8.7 years, 56.0 ± 10.4 years and 54.2 ± 7.1 years, respectively. Pain scores at baseline (P = 0.829), 2 months (P = 0.057) and 3 months follow-ups (p = 0.004) were 6.8 (4.7-7.7), 0.2 (0.0-0.5) and 0.3 (0.0-1.0) for group I; 6.6 (5.7-8.0), 0.5 (0.2-2.0) and 0.2 (0.0-3.3) for group II; and 6.5 (5.1-7.4), 2.4 (0.1-6.7) and 4.0 (2.0-5.0) for group III, respectively. SPADI scores at baseline (P = 0.029), 2 months (P < 0.001) and 3 months follow-ups (P = 0.001) were 60.8 (37.7-70.8), 3.8 (0.0-10.8) and 2.3 (0.8-10.8) for group I; 61.5 (41.5-71.5), 9.2 (3.8-29.2) and 14.2 (1.5-38.0) for the group II; and 73.3 (59.2-80.8), 34.2 (16.9-54.6) and 33.1 (22.3-49.2) for the group III, respectively.

CONCLUSION

Low-level laser therapy combined with exercises reduce pain intensity, improve shoulder function and reduces pain intensity and medication intake over 3 months.

Surgical treatments compared with early structured physiotherapy in secondary care for adults with primary frozen shoulder: the UK FROST three-arm RCT

BACKGROUND

Frozen shoulder causes pain and stiffness. It affects around 10% of people in their fifties and is slightly more common in women. Costly and invasive surgical interventions are used, without high-quality evidence that these are effective.

OBJECTIVES

To compare the clinical effectiveness and cost-effectiveness of three treatments in secondary care for adults with frozen shoulder; to qualitatively explore the acceptability of these treatments to patients and health-care professionals; and to update a systematic review to explore the trial findings in the context of existing evidence for the three treatments.

DESIGN

This was a pragmatic, parallel-group, multicentre, open-label, three-arm, randomised superiority trial with unequal allocation (2 : 2 : 1). An economic evaluation and a nested qualitative study were also carried out.

SETTING

The orthopaedic departments of 35 hospitals across the UK were recruited from April 2015, with final follow-up in December 2018.

PARTICIPANTS

Participants were adults (aged ≥ 18 years) with unilateral frozen shoulder, characterised by restriction of passive external rotation in the affected shoulder to < 50% of the opposite shoulder, and with plain radiographs excluding other pathology.

INTERVENTIONS

The inventions were early structured physiotherapy with a steroid injection, manipulation under anaesthesia with a steroid injection and arthroscopic capsular release followed by manipulation. Both of the surgical interventions were followed with post-procedural physiotherapy.

MAIN OUTCOME MEASURES

The primary outcome and end point was the Oxford Shoulder Score at 12 months post randomisation. A difference of 5 points between early structured physiotherapy and manipulation under anaesthesia or arthroscopic capsular release or of 4 points between manipulation under anaesthesia and arthroscopic capsular release was judged clinically important.

RESULTS

The mean age of the 503 participants was 54 years; 319 were female (63%) and 150 had diabetes (30%). The primary analyses comprised 473 participants (94%). At the primary end point of 12 months, participants randomised to arthroscopic capsular release had, on average, a statistically significantly higher (better) Oxford Shoulder Score than those randomised to manipulation under anaesthesia (2.01 points, 95% confidence interval 0.10 to 3.91 points; p = 0.04) or early structured physiotherapy (3.06 points, 95% confidence interval 0.71 to 5.41 points; p = 0.01). Manipulation under anaesthesia did not result in statistically significantly better Oxford Shoulder Score than early structured physiotherapy (1.05 points, 95% confidence interval -1.28 to 3.39 points; p = 0.38). No differences were deemed of clinical importance. Serious adverse events were rare but occurred in participants randomised to surgery (arthroscopic capsular release,n = 8; manipulation under anaesthesia,n = 2). There was, however, one serious adverse event in a participant who received non-trial physiotherapy. The base-case economic analysis showed that manipulation under anaesthesia was more expensive than early structured physiotherapy, with slightly better utilities. The incremental cost-effectiveness ratio for manipulation under anaesthesia was £6984 per additional quality-adjusted life-year, and this intervention was probably 86% cost-effective at the threshold of £20,000 per quality-adjusted life-year. Arthroscopic capsular release was more costly than early structured physiotherapy and manipulation under anaesthesia, with no statistically significant benefit in utilities. Participants in the qualitative study wanted early medical help and a quicker pathway to resolve their shoulder problem. Nine studies were identified from the updated systematic review, including UK FROST, of which only two could be pooled, and found that arthroscopic capsular release was more effective than physiotherapy in the long-term shoulder functioning of patients, but not to the clinically important magnitude used in UK FROST.

LIMITATIONS

Implementing physiotherapy to the trial standard in clinical practice might prove challenging but could avoid theatre use and post-procedural physiotherapy. There are potential confounding effects of waiting times in the trial.

CONCLUSIONS

None of the three interventions was clearly superior. Early structured physiotherapy with a steroid injection is an accessible and low-cost option. Manipulation under anaesthesia is the most cost-effective option. Arthroscopic capsular release carries higher risks and higher costs.

FUTURE WORK

Evaluation in a randomised controlled trial is recommended to address the increasing popularity of hydrodilatation despite the paucity of high-quality evidence.

Responsiveness to change over time and test-retest reliability of the PROMIS and Neuro-QoL mental health measures in persons with Huntington disease (HD)

BACKGROUND

The majority of persons with Huntington disease (HD) experience mental health symptoms. Patient-reported outcome (PRO) measures are capable of capturing unobservable behaviors and feelings relating to mental health. The current study aimed to test the reliability and responsiveness to self-reported and clinician-rated change over time of Neuro-QoL and PROMIS mental health PROs over the course of a 24-month period.

METHODS

At baseline, 12-months, and 24-months, 362 participants with premanifest or manifest HD completed the Neuro-QoL Depression computer adaptive test (CAT), PROMIS Depression short form (SF), Neuro-QoL Anxiety CAT, PROMIS Anxiety SF, PROMIS Anger CAT and SF, Neuro-QoL Emotional/Behavioral Dyscontrol CAT and SF, Neuro-QoL Positive Affect and Well-Being CAT and SF, and Neuro-QoL Stigma CAT and SF. Participants completed several clinician-administered measures at each time point, as well as several global ratings of change at 12- and 24-months. Reliability (test-retest reliability and measurement error) and responsiveness (using standardized response means and general linear models) were assessed.

RESULTS

Test-retest reliability and measurement error were excellent for all PROs (all ICC ≥ .90 for test-retest reliability and all SEM percentages ≤ 6.82%). In addition, 12- and 24-month responsiveness were generally supported for the Neuro-QoL and PROMIS mental health PROs; findings relative to clinician-rated anchors of change (e.g., SRMs for the group with declines ranged from .38 to .91 for 24-month change and .09 to .45, with the majority above .25 for 12-month change) were generally more robust than those relative to self-reported anchors of change (e.g., SRMs for the group with declines ranged from .02 to .75, with the majority above .39 for 24-month change and .09 to .45, with the majority above .16 for 12-month change).

CONCLUSIONS

The Neuro-QoL and PROMIS mental health PROs demonstrated strong psychometric reliability, as well as responsiveness to self-reported and clinician-rated change over time in people with HD.

Rehabilitation Interventions for Shoulder Dysfunction in Patients With Head and Neck Cancer: Systematic Review and Meta-Analysis

OBJECTIVE

Shoulder pain and dysfunction are highly prevalent after neck dissection in the treatment of head and neck cancer (HNC). They can lead to muscle weakness, limited range of motion, and shoulder tilt and pain, which can reduce patient functioning. The purpose of this study was to evaluate the effectiveness of rehabilitation interventions for shoulder dysfunction in patients with surgically treated HNC.

METHODS

A search of principal databases (MEDLINE, Embase, CENTRAL, LILACS, IBECS, PEDro, and SciELO) was conducted, in addition to hand searches and a search of gray literature, for all randomized clinical trials (RCTs) published before February 2020. Two authors independently selected all relevant studies. The 7 RCTs fulfilling all inclusion and exclusion criteria were assessed for risk of bias and certainty of evidence using the Cochrane Collaboration risk-of-bias tool and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool, respectively.

RESULTS

Moderate-certainty evidence suggests that progressive resistance training is better than conventional treatment for improving pain and dysfunction in patients with HNC (pooled data from 214 participants; mean difference = -5.92; 95% CI = -11.38 to -0.45). Low-certainty evidence (data from 2 RCTs with 106 participants that could not be combined) suggests that acupuncture seems to be more effective than conventional treatment.

CONCLUSIONS

Progressive resistance training is effective for improving shoulder pain and dysfunction in patients with HNC. Further high-quality RCTs are needed to examine the effectiveness of acupuncture for improving shoulder pain and dysfunction in these patients. Future studies with longer follow-up times are needed to clarify the effects of early postoperative intervention.

IMPACT

Clinicians can have confidence that progressive resistance training in patients with surgically treated HNC is effective.

LAY SUMMARY

These study results show that people with head and neck cancer can benefit from gradually increased resistance training to reduce shoulder pain and improve function. This study will help researchers design clinical trials to determine whether treatments such as acupuncture and early physical therapy also could be effective in treating this population.

A Novel Method for Gait Analysis on Center of Pressure Excursion Based on a Pressure-Sensitive Mat

Center of pressure (COP) during gait is a useful measure for assessing gait ability and has been investigated using platform or insole systems. However, these systems have inherent restrictions in repeated measure design or in obtaining true vertical force. This study proposes a novel method based on a pressure-sensitive mat system for COP measurement and presents normal reference values for the system. To explore repeatability, this work also investigated relative and absolute intra-rater reliabilities and determined the number of footfalls required to obtain a reliable measurement. Ninety healthy young adults participated and performed barefoot walking on a force-sensitive mat at a comfortable and fast pace. The time points and subphase duration of the stance phase, displacement ranges, and mean locations of COP and velocity of COP excursion were parameterized. The results showed acceptable and consistent variabilities of the parameters. Seven footfalls were determined as the threshold for most parameters to show a good to reasonable level of reliability. In conclusion, the presented method can be used as a reliable measurement for COP excursion, and it is recommended that more than seven footfalls be collected to ensure a high level of reliability.

Cervical spine thrust and non-thrust mobilization for the management of recalcitrant C6 paresthesias associated with a cervical radiculopathy: a case report

BACKGROUND

The conservative management of cervical radiculopathy is supported by moderate evidence to include interventions such as manual therapy, traction, and therapeutic exercise. There is sparse evidence, however, to support specific manual therapy techniques, particularly thrust manipulation.

CASE DESCRIPTION

A 35-year-old male presented to physical therapy with a clinical diagnosis of cervical radiculopathy. He complained of neck and upper arm pain with 1st and 2nd digit paresthesias. He was initially managed with repeated movements that restored the cervical range of motion and centralized neck and upper arm pain. Non-thrust upslope joint mobilizations resulted in improved sensation detection in the hand, but the paresthesias did not completely resolve. Immediately following cervical spine upslope thrust manipulation, symptoms fully resolved. Outcomes: The patient fully returned to prior level of function. His DASH score reduced from 40/100 to 2/100, PSFS improved from 1.66/10 to 9.66/10, and he reported to be 'a great deal better' on the GROC.

DISCUSSION

This case demonstrates the safe and effective utilization of cervical spine thrust manipulation and non-thrust mobilization in the management of a patient with cervical radiculopathy with lingering paresthesias in the distal upper extremity.

Mobility analysis of amputees (MAAT 3): Matching individuals based on comorbid health reveals improved function for above-knee prosthesis users with microprocessor knee technology

The objective of this cross-sectional observational study was to determine whether the use of a microprocessor knee for individuals with an above-the-knee amputation results in improved functional mobility compared to their peers of matched comorbid-health with a non-microprocessor knee, and to inform how this compares to the mobility observed in below-knee prosthesis users. A sample of 450 individuals with lower limb amputation were divided into three groups (n = 150 each). The groups included: nonmicroprocessor knee users (NMPK, age: 57.6 ± 17.2 years), microprocessor knee users (MPK, age: 56.5 ± 13.8 years), and below-knee prosthesis users (BKA, age: 58.4 ± 12.2 years). Primary outcome measure was functional mobility measured through Prosthetic Limb Users' Survey of Mobility (PLUS-M®). Results showed MPK mobility (48.49 ± 0.86) was greater than NMPK (43.49 ± 0.86, p < 0.001), but less than BKA (52.11 ± 0.86, p = 0.003). These results persisted when removing potential confounding effects of age, body mass index, cause of amputation, and comorbid health (MPK: 47.15 ± 0.97; NMPK: 43.47 ± 0.88; BKA: 52.61 ± 0.91). In conclusion, these results show the use of a MPK can improve functional mobility for individuals with an above-knee amputation.

Reproducibility and reliability of performance indicators to evaluate the therapeutic effectiveness of biofeedback therapy after elbow surgery: An observational case series

Electromyographic biofeedback (EMG-BF) therapy provides information on the state of contraction of the targeted muscles and relaxation of their antagonists, which can facilitate early active range of motion (RoM) after elbow surgery. Our aim in this study was to calculate the minimum detectable change (MDC) during EMG-BF therapy, initiated in the early postoperative period after elbow surgery.This study is an observational case series. EMG-BF of muscle contraction and relaxation was provided during active elbow flexion and extension exercises. Patients completed 3 sets of 10 trials each of flexion and extension over 4 weeks. The total range of flexion-extension motion and scores on the Japanese Society for Surgery of the Hand version of the disability of the arm, shoulder, and hand questionnaire and the Japanese version of the Patient-Rated Elbow Evaluation were obtained at baseline and weekly during the 4-week intervention period. A prediction formula was developed from the time-series data obtained during the intervention period, using the least-squares method. The estimated value was calculated by removing the slope from the prediction formula and adding the initial scores to residuals between the measured scores and predicted scores individually. Systematic error, MDC at the 95th percentile cutoff (MDC95), repeatability of the measures, and the change from the baseline to each time-point of intervention were assessed.The MDC95 was obtained for all 3 outcome measures and the range of values was as follows: RoM, 8.3° to 22.5°; Japanese version of the Patient-Rated Elbow Evaluation score, 17.6 to 30.6 points; and disability of the arm, shoulder, and hand questionnaire subscale: disability and symptoms score, 14.2 to 22.9 points.The efficacy of EMG-BF after elbow surgery was reflected in earlier initiation of elbow RoM after surgery and improvement in patient-reported upper limb function scores. The calculated MDC95 cut-offs could be used as reference values to assess the therapeutic effects of EMG-BF in individuals.

Later retirement, job strain, and health: Evidence from the new State Pension age in the United Kingdom

This paper examines the impact of raising the State Pension age on women's health. Exploiting a UK pension reform that increased women's State Pension age for up to 6 years since 2010, we show that raising the State Pension age leads to an increase of up to 12 percentage points in the probability of depressive symptoms, alongside an increase in self-reported medically diagnosed depression among women in a lower occupational grade. Our results suggest that these effects are driven by prolonged exposure to high-strain jobs characterised by high demands and low control. Effects are consistent across multiple subcomponents of the General Health Question and Short-Form-12 (SF-12) scores, and robust to alternative empirical specifications, including "placebo" analyses for women who never worked and for men.

Interrater and Test-Retest Reliability of Performance-Based Clinical Tests Administered to Established Users of Lower Limb Prostheses

OBJECTIVE

A major barrier to reducing falls among users of lower limb prostheses (LLP) has been an absence of statistical indices required for clinicians to select and interpret scores from performance-based clinical tests. The study aimed to derive estimates of reliability, measurement error, and minimal detectable change values in performance-based clinical tests administered to unilateral LLP users.

METHODS

A total of 60 unilateral LLP users were administered the Narrowing Beam Walking Test, Timed ``Up and Go'' (TUG), Four Square Step Test (FSST), and 10-Meter Walk Test on 2 occasions, 3 to 9 days apart. Intraclass correlation coefficients (ICCs) were calculated to assess interrater and test-retest reliability, while standard error of measurement (SEM) and minimal detectable change (MDC90) were derived to establish estimates of measurement error in individual scores or changes in score for each test.

RESULTS

Interrater reliability ICCs (1,1) were high for all tests (ie, ≥0.98). Test-retest ICCs (2,1) varied by test, ranging from .88 for the TUG to .97 for the FSST. SEM and MDC90 varied between .39 and .96 and between .91 seconds and 2.2 seconds for the time-based tests (FSST, TUG, 10-Meter Walk Test). SEM and MDC90 for the Narrowing Beam Walking Test were .07 and .16, respectively.

CONCLUSION

With the exception of the TUG, studied tests had test-retest ICCs (2,1) that exceeded the minimum required threshold to be considered suitable for group- and individual-level applications (ie, ICC ≥ 0.70 and ≥ 0.90, respectively). Future research on individuals with dysvascular and transfemoral amputations or in specific age categories is required.

IMPACT

Along with published validity indices, these reliability, error, and change indices can help clinicians select balance tests suitable for LLP users. They can also help clinicians interpret test scores to make informed, evidence-based clinical decisions.

Volar Locked Plating Versus Closed Reduction and Casting for Acute, Displaced Distal Radial Fractures in the Elderly: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND

It remains unclear whether volar locked plating (VLP) yields a better functional outcome than closed reduction and casting (CRC) for elderly patients with an acute, displaced distal radial fracture. Our purpose was to conduct a systematic review and meta-analysis of randomized controlled trials comparing outcomes of VLP and CRC for elderly patients (age, ≥60 years).

METHODS

Multiple databases, including MEDLINE, were searched for randomized controlled trials evaluating outcomes following distal radial fracture treatment. Raw data were obtained for studies that included patients of all ages, and the elderly subgroup was included for analysis. The primary outcome was the Disabilities of the Arm, Shoulder and Hand (DASH) score at ≥1 year of follow-up. Secondary outcomes included the 3-month DASH score, range of motion, final radiographic alignment, and complications. Effect sizes for the comparison of each outcome between groups were pooled across studies using random-effects models with the inverse variance weighting method. Changes in DASH score were compared with a minimal clinically important difference (MCID) estimate of 10 to assess clinical relevance.

RESULTS

Of 2,152 screened articles, 6 were included. Demographics were similar for the 274 VLP and 287 CRC patients. DASH scores were significantly better following VLP than CRC at the time of final follow-up (12 to 24 months postoperatively; score difference, -5.9; 95% confidence interval [CI], -8.7 to -3.1) and at 3 months (-8.9; 95% CI, -13.0 to -4.8). VLP yielded significantly better palmar tilt, radial inclination, and supination, with no differences in ulnar variance, flexion-extension, pronation, or total complication rates.

CONCLUSIONS

Functional outcome was significantly better following VLP than CRC 3 months into the treatment of acute, displaced distal radial fractures in an elderly population and up to 2 years after injury. However, the observed differences in the final DASH score did not exceed published estimates of the MCID, suggesting that clinical outcomes are similar for both treatment options.
