Fear of movement and emotional distress as prognostic factors for disability in patients with shoulder pain: a prospective cohort study

Physiotherapy experiences of injured immigrant workers in Quebec: an intersectional perspective

PURPOSE

Immigrant workers are more likely to suffer work-related injuries compared to native-born Canadians. Their physical rehabilitation usually involves physiotherapy. This study sought to better understand the experiences of injured immigrant workers receiving compensation and physiotherapy treatments.

MATERIALS AND METHODS

We conducted a qualitative study using an interpretive descriptive methodology. Semi-structured interviews were completed with 10 compensated immigrant workers about the physiotherapy services they received. Transcripts were analyzed thematically and with an intersectional lens.

RESULTS

Two major themes were identified: 1) complex pathways to physiotherapy, and 2) key pillars of physiotherapy experiences. The first theme demonstrates that a lack of familiarity with the health and compensation systems, delayed access to physiotherapy, and cumulative burdens complicate the care of immigrant workers. The second theme shows that moral/emotional support, pain relief, and the recognition of sociocultural beliefs and fears are key aspects to improving the experiences of care for these workers.

CONCLUSIONS

This study offers new insights into physiotherapy in the context of a work injury, which may help physiotherapists adapt care to the complex needs of immigrant workers. The intersectional lens used in the analysis offers interesting ways of accounting for the multiple social identities of these workers.

Effects of Adding Four Sessions of Ultrasound-Guided Percutaneous Electrical Nerve Stimulation to an Exercise Program in Patients with Shoulder Pain: A Randomized Controlled Trial

Objective: Percutaneous electrical nerve stimulation (PENS) appears to be effective for the treatment of musculoskeletal pain. The aim of this trial was to investigate the effects on disability and pain, as well as on the psychological aspects of adding PENS into an exercise program in patients with subacromial pain syndrome. Methods: A randomized, parallel-group clinical trial was conducted. Sixty patients with subacromial pain were allocated into exercise alone (n = 20), exercise plus PENS (n = 20), or exercise plus placebo PENS (n = 20) groups. Patients in all groups performed an exercise program twice daily for 3 weeks. Patients allocated to the PENS group also received four sessions of ultrasound-guided PENS targeting the axillar and suprascapular nerves. Patients allocated to the exercise plus placebo PENS received a sham PENS application. The primary outcome was related disability (Disabilities of the Arm, Shoulder, and Hand, DASH). Secondary outcomes included mean pain, anxiety levels, depressive symptoms, and sleep quality. They were assessed at baseline, one week after, and one and three months after. An analysis was performed using intention-to-treat with mixed-models ANCOVAs. Results: The results revealed no between-group differences for most outcomes (related disability: F = 0.292, p = 0.748, n2p = 0.011; anxiety: F = 0.780, p = 0.463, n2p = 0.027; depressive symptoms: F = 0.559, p = 0.575, n2p = 0.02; or sleep quality: F = 0.294, p = 0.747, n2p = 0.01); both groups experienced similar changes throughout the course of this study. Patients receiving exercise plus PENS exhibited greater improvement in shoulder pain at one month than those in the exercise (Δ -1.2, 95%CI -2.3 to -0.1) or the placebo (Δ -1.3, 95%CI -2.5 to -0.1) groups. Conclusions: The inclusion of four sessions of ultrasound-guided PENS targeting the axillar and suprascapular nerves into an exercise program did not result in better outcomes in our sample of patients with subacromial pain syndrome at one and three months after treatment.

Predicting outcomes across treatment settings in patients with shoulder pain referred to physiotherapy: a secondary analysis of two comparable prospective cohort studies

Objective

Previous studies have examined factors that may contribute to predicting outcomes for patients with shoulder pain. However, there is still a lack of consensus on which factors predict the results and whether there are differences based on the treatment setting. Thus, this study aimed to analyse and compare how baseline variables are associated with future outcomes in patients with shoulder pain in primary and secondary care settings.

Methods

This study conducted a secondary analysis of two observational prospective cohort studies involving patients with shoulder pain in primary care (n=150) and secondary care (n=183). Multiple regression analyses were employed, with one interaction term at a time, to examine potential differences in association with baseline characteristics and future outcomes between the two settings.

Results

Changes in pain and function were statistically significant at 6 months for patients in primary care and secondary care. However, associations for most baseline variables and outcomes did not differ significantly across these two treatment settings. The only statistically significant interactions observed were for the associations between baseline level of pain, function and fear avoidance beliefs and change in pain scores at 6 months, with lower change scores observed among patients in the secondary care.

Conclusion

This study revealed that the association with outcomes did not differ across settings for most baseline characteristics. These findings suggest that it could be feasible to generalise the prognostic value of most baseline variables for patients with shoulder, irrespective of the treatment setting.

Exercise for rotator cuff tendinopathy: Proposed mechanisms of recovery

Rotator cuff (RC) tendinopathy is a common recurrent cause of shoulder pain, and resistance exercise is the first-line recommended intervention. Proposed causal mechanisms of resistance exercise for patients with RC tendinopathy consist of four domains: tendon structure, neuromuscular factors, pain and sensorimotor processing, and psychosocial factors. Tendon structure plays a role in RC tendinopathy, with decreased stiffness, increased thickness, and collagen disorganization. Neuromuscular performance deficits of altered kinematics, muscle activation, and force are present in RC tendinopathy, but advanced methods of assessing muscle performance are needed to fully assess these factors. Psychological factors of depression, anxiety, pain catastrophizing, treatment expectations, and self-efficacy are present and predict patient-reported outcomes. Central nervous system dysfunctions also exist, specifically altered pain and sensorimotor processing. Resisted exercise may normalize these factors, but limited evidence exists to explain the relationship of the four proposed domains to trajectory of recovery and defining persistent deficits limiting outcomes. Clinicians and researchers can use this model to understand how exercise mediates change in patient outcomes, develop subgroups to deliver patient-specific approach for treatment and define metrics to track recovery over time. Supporting evidence is limited, indicating the need for future studies characterizing mechanisms of recovery with exercise for RC tendinopathy.

Determinants of Pain-Induced Disability in German Women with Endometriosis during the COVID-19 Pandemic

(1) Background: The main aim of this research was to examine the factors leading to pain-induced disability by assessing the impact of demographic, endometriosis-specific, pandemic-specific, and mental health factors. (2) Methods: Women with endometriosis who attended online support groups were invited to respond to an online survey during the first wave of the COVID-19 pandemic in Germany. The Pain Disability Index (PDI) was employed to assess disability-related daily functioning. Independent predictors of pain-induced disability were determined using univariate and multivariate logistic regression analyses. (3) Results: The mean PDI score of the study population was 31.61 (SD = 15.82), which was significantly higher (p < 0.001) than that reported in a previously published normative study of the German population. In the present study, a high level of pain-induced disability, as defined by scores equal to or higher than the median of the study population, older age (OR 1.063, 95% CI 1.010−1.120, p = 0.020), dysmenorrhea (OR 1.015, 95% CI 1.005−1.026, p = 0.005), dysuria (OR 1.014; 95% CI 1.001−1.027, p = 0.029), lower back pain (OR 1.018, 95% CI 1.007−1.029, p = 0.001), and impaired mental health (OR 1.271, 95% CI 1.134−1.425, p < 0.001) were found to be independent risk factors. Pandemic-specific factors did not significantly influence the pain-induced disability of the participants in this study. (4) Conclusions: The level of pain-induced disability was significantly higher among the women with endometriosis than among women in the normative German validation study. Our findings identified risk factors for experiencing a high level of pain-induced disability, such as demographic and specific pain characteristics. Pandemic-specific factors did not significantly and independently influence the pain-induced disability during the first wave of the COVID-19 pandemic in Germany. Impaired mental health negatively influenced functioning during daily activities. Thus, women with endometriosis should be managed by a multidisciplinary team of healthcare professionals to prevent negative effects of pain-induced disability on their quality of life.
