Kinesiophobia Is Associated With Pain Intensity and Disability in Chronic Shoulder Pain: A Cross-Sectional Study

The relationship between kinesiophobia, balance, and upper extremity functions in patients with painful shoulder pathology

BACKGROUND

Poor balance ability may contribute to shoulder pathology in patients with existing shoulder pathologies or vice versa. The relationship between kinesiophobia and chronic shoulder pain intensity has been researched, although the conclusions are conflicting. To our knowledge, no study in the literature explores the association between kinesiophobia and balance in patients with shoulder pain.

OBJECTIVE

To investigate the relationship between kinesiophobia, upper extremity functions, and balance abilities in patients with shoulder pain.

DESIGN

Cross-sectional observational study.

SETTING

Physical medicine and rehabilitation hospital.

INTERVENTIONS

Not applicable.

PARTICIPANTS

A total of 44 patients with shoulder pain were included in the study.

MAIN OUTCOME MEASURES

The pain severity was assessed using a visual analog scale (VAS). The Tampa Scale for Kinesiophobia (TSK), Berg Balance Scale (BBS), and Shoulder Pain and Disability Index (SPADI) were used to assess the patients. Ultrasound was used to diagnose underlying shoulder joint problems. Static and dynamic postural control was evaluated.

RESULTS

The most common pathologies detected by ultrasound were supraspinatus tendinitis/rupture (77.3%), cortical irregularity (68.2%), and bursitis (63.6%). TSK score did not correlate with age, body mass index, symptom duration, or VAS score in rest (all p > .05), but it was associated with scores on the BBS (r = -0.437, p = .003), SPADI-pain (r = 0.474, p = .001), SPADI-disability (r = 0.355, p = .018), SPADI-total (r = 0.405, p = .006), and VAS in activity (r = 0.331, p = .028). According to multiple linear regression analysis, BBS score, SPADI-total score, and anterior-posterior sway length were significant predictors of TSK (r = 0.645, r2 = 0.416).

CONCLUSIONS

According to the findings of this study, the main risk factors for high levels of kinesiophobia are poor balance, severe pain, and disability. In addition to mechanical causes of shoulder pain, diagnosing and intervening on underlying balance issues and psychosocial causes of shoulder pain will improve treatment success.

Tackling Kinesiophobia in Chronic Shoulder Pain: A Case Report on the Combined Effect of Pain Education and Whole-Body Cryostimulation

BACKGROUND

Chronic shoulder pain may cause significant functional disability and reduced psychosocial well-being. Detailed Case Description: In this case, we propose the use of pain neuroscience education and whole-body cryostimulation (WBC) to treat a 64-year-old woman with severe functional limitations and chronic right shoulder pain. The aim was to overcome kinesiophobia and improve her motor function, autonomy, and quality of life. Functional and clinical assessments were conducted at admission, discharge, and at a one-month follow-up via phone call. The patient's global health, shoulder function, and quality of life showed improvement during hospitalisation and were maintained after one month.

DISCUSSION

Pain education is crucial in managing chronic shoulder pain, especially in addressing kinesiophobia and promoting positive patient outcomes. In this context, WBC was used as a supplementary treatment to traditional pain relief and exercise tolerance therapies. This can help individuals to participate more actively in their rehabilitation process, ultimately promoting functional recovery and an improved quality of life.

CONCLUSION

The combination of cryostimulation, tailored physical exercises, pain education, manual therapy, and psychological support created a synergistic effect that addressed both the physical and psychological aspects of pain and kinesiophobia.

Which Psychological and Psychosocial Constructs Are Important to Measure in Future Tendinopathy Clinical Trials? A Modified International Delphi Study With Expert Clinician/Researchers and People With Tendinopathy

OBJECTIVE: To identify which psychological and psychosocial constructs to include in a core outcome set to guide future clinical trials in the tendinopathy field. DESIGN: Modified International Delphi study. METHODS: In 3 online Delphi rounds, we presented 35 psychological and psychosocial constructs to an international panel of 38 clinician/researchers and people with tendinopathy. Using a 9-point Likert scale (1 = not important to include, 9 = critical to include), consensus for construct inclusion required ≥70% of respondents rating "extremely critical to include" (score ≥7) and ≤15% rating "not important to include" (score ≤3). Consensus for exclusion required ≥70% of respondents rating "not important to include" (score ≤3) and ≤15% of rating "critical to include" (score ≥7). RESULTS: Thirty-six participants (95% of 38) completed round 1, 90% (n = 34) completed round 2, and 87% (n = 33) completed round 3. Four constructs were deemed important to include as part of a core outcome set: kinesiophobia (82%, median: 8, interquartile range [IQR]: 1.0), pain beliefs (76%, median: -7, IQR: 1.0), pain-related self-efficacy (71%, median: 7, IQR: 2.0), and fear-avoidance beliefs (73%, median: -7, IQR: 1.0). Six constructs were deemed not important to include: perceived injustice (82%), individual attitudes of family members (74%), social isolation and loneliness (73%), job satisfaction (73%), coping (70%), and educational attainment (70%). Clinician/researchers and people with tendinopathy reached consensus that kinesiophobia, pain beliefs, pain self-efficacy, and fear-avoidance beliefs were important psychological constructs to measure in tendinopathy clinical trials.

Immersive virtual reality in orthopaedics-a narrative review

PURPOSE

This narrative review explores the applications and benefits of immersive virtual reality (VR) in orthopaedics, with a focus on surgical training, patient functional recovery, and pain management.

METHODS

The review examines existing literature and research studies on immersive VR in orthopaedics, analyzing both experimental and clinical studies.

RESULTS

Immersive VR provides a realistic simulation environment for orthopaedic surgery training, enhancing surgical skills, reducing errors, and improving overall performance. In post-surgical recovery and rehabilitation, immersive VR environments can facilitate motor learning and functional recovery through virtual embodiment, motor imagery during action observation, and virtual training. Additionally VR-based functional recovery programs can improve patient adherence and outcomes. Moreover, VR has the potential to revolutionize pain management, offering a non-invasive, drug-free alternative. Virtual reality analgesia acts by a variety of means including engagement and diverting patients' attention, anxiety reduction, and specific virtual-body transformations.

CONCLUSION

Immersive virtual reality holds significant promise in orthopaedics, demonstrating potential for improved surgical training, patient functional recovery, and pain management but further research is needed to fully exploit the benefits of VR technology in these areas.

Specific versus general exercise programme in adults with subacromial impingement syndrome: a randomised controlled trial

Objectives

Current evidence on the clinical effectiveness about the different types of exercises in the subacromial impingement syndrome (SIS) remains controversial. This study aims to compare the short-term (at 5 weeks) effects of a specific exercise programme with a general exercise programme on shoulder function in adults with SIS.

Methods

In total, 52 adults with SIS were randomly allocated to 5 weeks to perform specific exercises (experimental group, n=26) or general exercises (control group, n=26). The primary outcome was change in shoulder function, it was assessed using the Shoulder Pain and Disability Index (SPADI) from baseline to 5 weeks. Secondary end points included changes in upper limb function (Disabilities of the Arm, Shoulder, and Hand (DASH) Questionnaire), pain intensity (Visual Analog Scale (VAS)) and kinesiophobia (Tampa Scale of Kinesiophobia (TSK)).

Results

All participants completed the trial. The between-group differences at 5 weeks were: SPADI, 13.5 points (95% CI: 4.3 to 15.6; ƞ2=0.22; p=0.001); DASH, 10.1 points (95% CI: 5.6 to 15.2; ƞ2=0.27; p<0.001); VAS at rest, 0.2 cm (95% CI: 0.1 to 0.3; ƞ2=0.07; p=0.553); VAS on movement, 1.7 cm (95% CI: 0.9 to 2.2; ƞ2=0.24; p<0.001); and TSK, 16.3 points (95% CI: 13.2 to 15.3; ƞ2=0.33; p<0.001). All differences favoured the experimental group and effect sizes were medium to large for most outcomes. Mediation analyses showed that the effect of the specific exercises on shoulder function was mediated by kinesiophobia (β=2.800; 95% CI: 1.063 to 4.907) and pain on movement (β= -0.690; 95% CI: -1.176 to -0.271).

Conclusion

In adults with SIS, specific exercises may have a larger effect than general exercises. However, most differences did not reach the minimum threshold to be considered clinically important and the evidence to support exercise as standard treatment warrant further study.

Virtual embodiment for improving range of motion in patients with movement-related shoulder pain: an experimental study

BACKGROUND

Recent evidence supports the use of immersive virtual reality (VR) as a means of delivering bodily illusions that may have therapeutic potential for the treatment of musculoskeletal conditions. We wanted to investigate whether a single session of an embodiment-based immersive VR training program influences pain-free range of motion in patients with shoulder pain.

METHODS

We designed a rehabilitation program based on developing ownership over a virtual body and then "exercising" the upper limb in immersive VR, while the real arm remains static. We then carried out a single-arm pre-post experiment in which 21 patients with movement-related musculoskeletal shoulder pain were exposed to the 15-min VR program and measured their active pain-free range of motion immediately before and afterwards.

RESULTS

We found that shoulder abduction and hand-behind-back movements, but not shoulder flexion, were significantly and clinically improved post-intervention and that the level of improvement correlated with the level of embodiment. Following this one session, at 1-week follow-up the improvements were not maintained.

CONCLUSIONS

Virtual embodiment may be a useful therapeutic tool to help improve range of motion in patients with movement-related shoulder pain in the short term, which in turn could expedite rehabilitation and recovery in these conditions.

Are clinical outcomes associated with baseline sensory profiles in people with musculoskeletal shoulder pain? Protocol for a prospective longitudinal observational study

BACKGROUND

Musculoskeletal shoulder pain is a common problem and its symptoms often become persistent. The experience of pain is multidimensional, and therefore, a range of patient characteristics may influence treatment response. An altered sensory processing has been associated with persistent musculoskeletal pain states and may contribute to outcomes in patients with musculoskeletal shoulder pain. The presence and potential impact of altered sensory processing in this patient cohort is not currently known. The aim of this prospective longitudinal cohort study is to investigate if baseline sensory characteristics are associated with clinical outcomes in patients presenting to a tertiary hospital with persistent musculoskeletal shoulder pain. If found, a relationship between sensory characteristics and outcome may lead to the creation of more effective treatment strategies and improvements in risk adjustment and prognosis.

METHODS

This is a single-centre prospective cohort study with 6-, 12- and 24-month follow-up. A total of 120 participants aged ≥18 years with persistent musculoskeletal shoulder pain (≥3 months) will be recruited from an Australian public tertiary hospital orthopaedic department. Baseline assessments, including quantitative sensory tests and a standardised physical examination, will be performed. In addition, information will be obtained from patient interviews, self-report questionnaires and medical records. Follow-up outcome measures will comprise information from the Shoulder Pain and Disability Index and a six-point Global Rating of Change scale.

ANALYSIS

Descriptive statistics will be used to report baseline characteristics and outcome measures over time. Change in outcome measures at the primary endpoint of six months from baseline will be calculated using paired t-tests. Associations between baseline characteristics and outcomes at a 6-month follow-up will be reported using multivariable linear and logistic regression models.

DISCUSSION

Understanding the relationship between sensory profile and the variable response to treatment in people with persistent musculoskeletal shoulder pain may enhance our understanding of the mechanisms contributing to the presentation. In addition, through better understanding of the contributing factors, the results of this study may contribute to the development of an individualised, patient-centred approach to treatment for people with this highly prevalent and debilitating condition.

Fear-Avoidance Beliefs Are Associated with Pain Intensity and Shoulder Disability in Adults with Chronic Shoulder Pain: A Cross-Sectional Study

Shoulder pain is one of the most common musculoskeletal conditions, and for people over 40 years old, it represents the musculoskeletal pain with the greatest impact on quality of life. Psychological factors, such as fear-avoidance beliefs, are associated with musculoskeletal pain, and several studies suggest that they can influence various treatment outcomes. Our objective was to explore the cross-sectional association between fear-avoidance beliefs and shoulder pain intensity and disability in subjects with chronic shoulder pain. A cross-sectional study was conducted, and 208 participants with chronic unilateral subacromial shoulder pain were recruited. The shoulder pain and disability index assessed pain intensity and disability. The Spanish fear-avoidance components scale assessed the presence of fear-avoidance beliefs. The association between fear-avoidance beliefs and pain intensity and disability was analyzed by means of multiple linear regression models and proportional odds models, reporting odds ratios and 95% confidence intervals. Shoulder and pain disability scores were significantly associated with fear-avoidance beliefs (p < 0.0001, adjusted R-square 0.93, multiple linear regression). There was no evidence of an association between sex and age in this study. The regression coefficient for shoulder pain intensity and disability score was 0.67446. The proportional odds model showed an odds ratio of 1.39 (1.29-1.50) for shoulder pain intensity and disability total score. This study suggests that greater levels of fear-avoidance beliefs are associated with greater levels of shoulder pain and disability in adults with chronic shoulder pain.

The Mediation Effect of Pain on the Relationship between Kinesiophobia and Lumbar Joint Position Sense in Chronic Low Back Pain Individuals: A Cross-Sectional Study

(1) Background: Fear of movement (kinesiophobia) and impaired lumbar joint position sense (LJPS) play a vital role in developing and maintaining non-specific chronic low back pain (CLBP). However, how kinesiophobia impacts LJPS is still being determined. The aims of this study are to (1) assess the correlation between kinesiophobia and LJPS in individuals with chronic low back pain; (2) compare LJPS between individuals with CLBP and those who are asymptomatic; and (3) evaluate if pain can mediate the relationship between kinesiophobia and LJPS in CLBP individuals. (2) Methods: Eighty-three individuals (mean age = 48.9 ± 7.5 years) with a diagnosis of CLBP and 95 asymptomatic individuals (mean age = 49.4 ± 7.0 years) were recruited into this cross-sectional study. Fear of movement in CLBP individuals was assessed using the Tampa Scale for Kinesiophobia (TSK). LJPS was determined using the active target repositioning technique using a dual-digital inclinometer. LJPS was evaluated in lumbar flexion, extension, and side-bending left and right directions, and the repositioning accuracy was determined in degrees using a dual digital inclinometer. (3) Results: Kinesiophobia showed a significant (p < 0.001) moderate positive correlation with LJPS (flexion: r = 0.51, extension: r = 0.41, side-bending left: r = 0.37 and side-bending right: r = 0.34). LJPS errors were larger in CLBP individuals compared to asymptomatic individuals (p < 0.05). Mediation analyses showed that pain significantly mediated the relationship between kinesiophobia and LJPS (p < 0.05) in CLBP individuals. (4) Conclusions: Kinesiophobia and LJPS were positively associated. LJPS is impaired in CLBP individuals compared to asymptomatic individuals. Pain may mediate adverse effects on LJPS. These factors must be taken into account when assessing and developing treatment plans for those with CLBP.

Biopsychosocial Approach in Identifying Risk Factors of Kinesiophobia in Persons with Subacromial Pain Syndrome and Developing a Clinical Prediction Tool

Introduction

Although the negative effects of kinesiophobia on functional status in subacromial pain syndrome (SAPS) patients are clearly demonstrated, no study examines the risk factors of kinesiophobia in individuals with SAPS from a biopsychosocial perspective. The present study aims to determine the risk factors of kinesiophobia in individuals with SAPS using a biopsychosocial approach. This study also aims to explore the compounding effects of multiple associative risk factors by developing a clinical prediction tool to identify SAPS patients at higher risk for kinesiophobia.

Materials and methods

This cross-sectional study included 549 patients who were diagnosed with SAPS. The Tampa-Scale of Kinesiophobia (TSK) was used to assess kinesiophobia. Visual analog scale (VAS), The Shoulder Pain and Disability Index (SPADI), Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, the presence of metabolic syndrome, using any non-steroidal anti-inflammatory drugs, Pain Catastrophizing Scale (PCS), Illness Perception Questionnaire-revised (IPQ-R), Hospital Anxiety and Depression Scale (HADS), behavioral pattern of the patient, sociodemographic characteristics, and treatment expectancy were outcome measures.

Results

Thirteen significant risk factors of having kinesiophobia were: VASat rest (≥ 5.2), VASduring activity (≥ 7.1), DASH (≥ 72.1), presence of metabolic syndrome, PCShelplessness (≥ 16.1), IPQ-Rpersonal control (≤ 17.1), IPQ-Rtreatment control (≤ 16.3), HADSdepression (≥ 7.9), avoidance behavior type, being female, educational level (≤ high school), average hours of sleep (≤ 6.8), and treatment expectancy (≤ 6.6). The presence of seven or more risk factors increased the probability of having high level of kinesiophobia from 34.3 to 51%.

Conclusions

It seems necessary to address these factors, increase awareness of health practitioners and individuals.

Kinesiophobia in patients with angina pectoris of coronary artery disease: A cross-sectional survey

BACKGROUND

In the field of chronic pain research, kinesiophobia is defined as avoidance behavior due to fear of pain, but this perspective seems to be neglected in the field of coronary artery disease (CAD).

OBJECTIVE

To investigate the status quo of angina pectoris (AP) and kinesiophobia and factors associated with kinesiophobia in patients with AP of CAD.

METHODS

This was a cross-sectional study. Participants were recruited by convenience sampling, and patients with AP of CAD in four wards of the Cardiology Department of a hospital were enrolled in this study. Participants completed questionnaires and scales face-to-face with researchers.

RESULTS

Most patients with AP of CAD suffered from at least moderate pain episodes (60.2%) of at least 5 minutes per episode (53.8%), but less than 1/3 of patients reached 5 instances of pain per week (29.1%). The total score of kinesiophobia in patients was 40.80±6.65, and the vast majority of patients had moderate to high levels of kinesiophobia (75.7%). The results of multiple linear stepwise regression analysis showed that personal monthly income, New York Heart Function Assessment (NYHA) classification, pain intensity, and pain resilience were independent factors associated with kinesiophobia, and these factors explained 30.2% of the variation in total scores of kinesiophobia.

CONCLUSION

The symptoms of AP were prominent in terms of pain intensity and duration of pain. The level of kinesiophobia was moderate, and this was affected by multiple factors. Health care providers and researchers seldom pay attention to the kinesiophobia of patients with AP of CAD. This study refocused on the effect of "fear of pain" in kinesiophobia in patients with CAD. It opens up new horizons for the application of fear-avoidance models in CAD patients and helps to raise awareness of kinesiophobia in AP patients with CAD and provides guidance for reducing the level of kinesiophobia in the future.

Fear of movement and its associated psychosocial factors in heart failure patients: A cross-sectional study

AIMS

Fear of movement is a significant obstacle to daily activities, which may lead to adverse outcomes in patients with heart failure. This study aimed to examine the prevalence of fear of movement and to identify psychosocial factors associated with fear of movement in heart failure patients.

METHODS AND RESULTS

In this cross-sectional study, a total of 305 heart failure patients were recruited from three cardiovascular units of a university hospital. Self-reported questionnaires were used to measure fear of movement, cardiac anxiety, depressive symptoms, subjective social status, education, monthly income, and employment status. The results showed that 178 (58.4%) patients were accompanied with fear of movement. Hierarchical linear regression analysis showed that scores for cardiac anxiety (β=0.254, p < 0.001) and depressive symptoms (β=0.308, p < 0.001), as well as being employed (β=0.186, p < 0.001) were positively associated with fear of movement score, while the score for subjective social status (β=-0.101, p = 0.038) was negatively associated with fear of movement score. The four independent variables accounted for 30.3% of the variance in fear of movement.

CONCLUSIONS

Fear of movement is common in patients with heart failure. Cardiac anxiety, depressive symptoms, subjective social status, and employment status were associated with patients' fear of movement. This indicates that measures should be taken to screen and manage patients' fear of movement. Furthermore, alleviating cardiac anxiety and depressive symptoms may be important to consider in relieving fear of movement in heart failure patients, especially for those who are employed and with low subjective social status.

Kinesiophobia could affect shoulder function after repair of rotator cuff tears

Purpose

Kinesiophobia (fear of movement) is a major limiting factor in the return to pre-injury sport level after surgery of rotator cuff tears. The study aims to gain insights into how kinesiophobia affects shoulder pain and function after the repair of full-thickness rotator cuff tears.

Methods

A prospective study was conducted to evaluate patients who underwent rotator cuff repair between January 2019 and December 2019 in our institution. The patients were divided into a trial group with a high kinesiophobia (Tampa Scale for Kinesiophobia [TSK], TSK > 37) and a control group with a low kinesiophobia (TSK ≤ 37). The indicators of interest included the Constant-Murley scores, numerical rating scale (NRS), visual analogue scale (VAS), Oxford Shoulder Score (OSS), and the American shoulder and elbow score (ASES), shoulder function and strength, and range of motion (ROM) at 3 days, 6 weeks, and 12 months after repair of full-thickness rotator cuff tears.

Results

In total, 49 patients who underwent repair of full-thickness rotator cuff tears were enrolled, which was divided into a trial group involving 26 patients (mean TSK 52.54) and a control group involving 23 patients (mean TSK 33.43). There were no statistically significant differences in basic information such as age, gender, and length of stay in the two groups. The preoperative and early postoperative functional scores and the Tampa Scale for Kinesiophobia were statistically significant differences between the two groups. However, long-term postoperative follow-up showed no statistically significant difference in ASES, and Constant-Murley scores, OSS, and VAS scores between the two groups as the kinesiophobia changed from positive to negative.

Conclusion

Degree of kinesiophobia reduced during post-operative rehabilitation of rotator cuff repair patients, but high kinesiophobia is still present in a large portion of the patients after rotator cuff repair. Patients after rotator cuff repair will benefit from early recognition and prevention of kinesiophobia.

Effectiveness of graded motor imagery in subjects with frozen shoulder: a pilot randomized controlled trial

Background

Subjects with frozen shoulder (FS) might not be comfortable with vigorous physical therapy. Clinical trials assessing the effect of graded motor imagery (GMI) in FS are lacking. The aim of this study was to determine the effect of GMI as an adjunct to conventional physiotherapy in individuals with painful FS.

Methods

Twenty subjects aged 40–65 years having stage I and II of FS were randomly divided into two study groups. The conventional physiotherapy group (n = 10) received electrotherapy and exercises while the GMI group (n = 10) received GMI along with the conventional physiotherapy thrice a week for 3 weeks. Pre- (Session 1) and post- (Session 9) intervention analysis for flexion, abduction, and external rotation range of motion (ROM) using a universal goniometer, fear of movement using the fear avoidance belief questionnaire (FABQ), pain with the visual analogue scale, and functional disability using the shoulder pain and disability index (SPADI) was done by a blinded assessor.

Results

Statistically significant difference was seen within both the groups for all the outcomes. In terms of increasing abduction ROM as well as reducing fear of movement, pain, and functional disability, the GMI group was significantly better than control group. However, both groups were equally effective for improving flexion and external rotation ROM.

Conclusions

Addition of GMI to the conventional physiotherapy proved to be superior to conventional physiotherapy alone in terms of reducing pain, kinesiophobia, and improving shoulder function for stage I and II of FS.

Kinesiophobia in People with Multiple Sclerosis and Its Relationship with Physical Activity, Pain and Acceptance of Disease

Background and Objectives: Multiple sclerosis (MS) is the most common chronic demyelinating disease. Factors that reduce the occurrence of symptoms include physical activity (PA). However, the data indicate that PA levels among people with MS are lower than those of healthy peers. The cause may be kinesiophobia. The aim of the study was to determine the level of kinesiophobia among people with MS and its relationship with age, disease duration, functional status, PA, and degree of acceptance of the disease. Materials and Methods: Eighty people aged 35−69 were examined: 60 women (75%) and 20 men (25%). The Expanded Disability Status Scale (EDSS) was used to determine the level of disability (median: 3.50; min−max: 1−6). The research questionnaire consisted of a metric section, Visual Analogue Scale (VAS) for pain, Tampa Scale of Kinesiophobia (TSK), Acceptance of Illness Scale (AIS), and Modified Baecke Questionnaire for Older Adults for physical activity. Results: Of the respondents, 52.50% were characterized by a high level of kinesiophobia (>37 points). Correlation analysis: TSK and PA showed the following: r = −0.363 (p = 0.001). Regression explains kinesiophobia in 44% (R2 = 0.4364; p < 0.0000). The predictors of TSK were as follows: disability level: p < 0.01, ß = 0.33; disease acceptance: p < 0.01, ß = −0.34; PA: p < 0.05, ß < −0.05. Conclusions: The problem of kinesiophobia is significant in MS patients, and its predictors are the functional status of the patients, low degree of acceptance of the disease, and low level of physical activity. The age and duration of the disease do not determine the problem of fear of movement.

Do psychological factors relate to movement-evoked pain in people with musculoskeletal pain? A systematic review and meta-analysis

BACKGROUND

A growing body of evidence has demonstrated the importance of implementing movement-evoked pain in conventional pain assessments, with a significant role for psychological factors being suggested. Whether or not to include these factors in the assessment of movement-evoked pain has not yet been determined.

OBJECTIVES

The aim of this systematic review is to explore the association between psychological factors and movement-evoked pain scores in people with musculoskeletal pain.

METHODS

For this systematic review with meta-analysis, four electronic databases (PubMed, Medline, WOS, and Scopus) were searched. Cross-sectional studies, longitudinal cohort studies, and randomized controlled trials investigating the association between movement-evoked pain and psychological factors in adults with musculoskeletal pain were considered. Meta-analysis was conducted for outcomes with homogeneous data from at least 2 studies. Fischer-Z transformations were used as the measure of effect. Quality of evidence was assessed using the National Institutes of Health's Quality assessment tool for observational cohort and cross-sectional studies and Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework.

RESULTS

Meta-analyses and grading the quality of evidence revealed moderate evidence for a relation between movement-evoked pain and depressive symptoms (Fisher-z=0.27; 95%CI: 0.17, 0.36; 5 studies (n=440)), pain-related fear (Fisher-z=0.35; 95%CI: 0.26, 0.44; 6 studies (n=492)), and pain catastrophizing (Fisher-z=0.47; 95%CI: 0.36, 0.58; 4 studies (n=312)) in people with musculoskeletal pain.

CONCLUSIONS

Movement-evoked pain is weakly to moderately associated to depressive symptoms, pain-related fear, and pain catastrophizing in people with musculoskeletal pain.

Is Shoulder Pain and Disability Index a Prognostic Factor for Neuropathic Shoulder Pain?

Introduction

So far, investigations in patients with rotator cuff diseases have used pain measurement tools such as visual analog scale (VAS) for nociceptive pain as well as neuropathic pain (NeuP) specialized ones like Douleur Neuropathique 4 Question (DN4) and Pain Detect. The study’s goal was to look at the existence of NeuP in patients with chronic shoulder pain, as well as variables that may be predictive of its progression.

Methods

There were 112 outpatients in all. Current and previous pain intensity levels were documented with the numerical rating scale (NRS), the Shoulder Pain and Disability Index (SPADI) was used to assess pain and disability levels, and the S-LANSS (self-completed Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale) was used to diagnose NeuP. The Pearson Chi-Square test was employed to check for any relationships between variables. The Mann-Whitney U test was also employed to check for between-group differences (with or without NeuP). To investigate factors that may be utilized as a prognostic for NeuP, logistic regression was performed, with those components (from the univariate analysis) that were statistically significant being included.

Results

According to the S-LANSS questionnaire for NeuP diagnosis, 21 patients had NeuP. According to S-LANSS, chi-square test findings revealed that NeuP is independent of sex, smoking, size, and location or rotator cuff tear. Univariate analysis with Mann-Whitney U test revealed statistically significant differences in SPADI and NRS scores between the two patient groups (p < 0.001). Α multivariate analysis using S-LANSS as the binary dependent variable and NRS currently, NRS average last month and SPADI total score as independent variables (with statistical significance) revealed that total SPADI score may be considered as an independent prognostic factor for NeuP (odds ratio = 1.189, p < 0.001).

Limitations

Due to the limited number of patients who participated in the study, the findings were deemed insufficient in terms of statistical power. In particular, the power analysis of the study (type I error probability being [a] = .05) was less than 80% (for the total SPADI score), hence relatively small. As a result, there is a limited probability of a type I error.

Conclusions

Using S-LANSS, we discovered that 18.8% of patients with rotator cuff tears had NeuP. The SPADI scores (pain and disability) in the NeuP group were substantially greater than in the nociceptive pain group. As previous studies have suggested utilizing certain levels of the VAS for pain assessment and specialized questionnaires for NeuP evaluation, we recommend that SPADI be included as a tool for emphasizing the neuropathic features of shoulder pain.

Biopsychosocial Aspects in Individuals with Acute and Chronic Rotator Cuff Related Shoulder Pain: Classification Based on a Decision Tree Analysis

Biopsychosocial aspects seem to influence the clinical condition of rotator cuff related shoulder pain (RCRSP). However, traditional bivariate and linear analyses may not be sufficiently robust to capture the complex relationships among these aspects. This study determined which biopsychosocial aspects would better classify individuals with acute and chronic RCRSP and described how these aspects interact to create biopsychosocial phenotypes in individuals with acute and chronic RCRSP. Individuals with acute (<six months of pain, n = 15) and chronic (≥six months of pain, n = 38) RCRSP were included. Sociodemographic data, biological data related to general clinical health status, to shoulder clinical condition and to sensory function, and psychosocial data were collected. Outcomes were compared between groups and a decision tree was used to classify the individuals with acute and chronic RCRSP into different phenotypes hierarchically organized in nodes. Only conditioned pain modulation was different between the groups. However, the tree combined six biopsychosocial aspects to identify seven distinct phenotypes in individuals with RCRSP: three phenotypes of individuals with acute, and four with chronic RCRSP. While the majority of the individuals with chronic RCRSP have no other previous painful complaint besides the shoulder pain and low efficiency of endogenous pain modulation with no signs of biomechanical related pain, individuals with acute RCRSP are more likely to have preserved endogenous pain modulation and unilateral pain with signs of kinesiophobia.
