The aims of the present study were to (i) cross-culturally adapt a Danish consensus version of the 10-item Perceived Stress Scale (PSS-10) and (ii) evaluate its psychometric properties in terms of agreement, reliability, validity, responsiveness, and interpretability among patients with work-related stress complaints. A consensus-building process was performed involving the authors of the three previous Danish translations and the consensus version was back-translated into English and pilot-tested. Psychometric properties of the final version were examined in a sample of 64 patients with work-related stress complaints. The face validity, reliability, and internal consistency of the Danish consensus version of the PSS-10 were satisfactory, and convergent construct validity was confirmed. Receiver operating characteristic (ROC) curves of the change scores showed that the ability of the PSS-10 to correctly classify patients as improved or unchanged according to the patients' own judgment was acceptable. The estimates of minimal clinically important change were 11 points and 28% for absolute and relative change scores, respectively. The Danish consensus version of the PSS-10 appears to be feasible for use in clinical research settings and has good psychometric properties in terms of agreement, reliability, validity, responsiveness, and interpretability.

Exercise is frequently suggested as a treatment option for patients presenting with symptoms of subacromial impingement syndrome. Some would argue implementing a specific exercise strategy with special focus on correction of kinematic deficits would be superior to general exercise strategy. There is however a lack of evidence comparing such exercise strategies to determine which is the most effective in the treatment of subacromial impingement syndrome. The aim of this review is to evaluate whether implementing specific exercise strategies involving resistive exercises are more effective than a general exercise strategy for the treatment of patients with subacromial impingement syndrome. Randomized controlled trials were identified through an electronic search on PubMed/MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science and PEDro. In addition, article reference lists and Clinicaltrials.gov were searched. Studies were considered eligible if they included interventions with resistive specific exercises as compared to general resistance exercise. Four reviewers assessed risk of bias and methodological quality guided by Cochrane recommendations. Results were synthesised qualitatively or quantitatively, where appropriate. Six randomized controlled trials were included with 231 participants who experienced symptoms of subacromial impingement syndrome. Four studies evaluated the effectiveness of specific scapular exercise strategy and two studies evaluated the effectiveness of specific proprioceptive strategy. Five studies were of moderate quality and one study was of low quality. No consistent statistical significant differences in outcomes between treatment groups were reported in the studies. Standardized mean difference (SMD) for pain was SMD −0.19 (95% CI −0.61, 0.22) and SMD 0.30 (95% CI −0.16, 0.76) for function. There is insufficient evidence to support or refute the effectiveness of specific resistive exercise strategies in the rehabilitation of subacromial impingement syndrome. More high quality research is needed to accurately assess this. This review provides suggestions on how to improve the methodological design of future studies in this area.

Study Design: A prospective cohort study nested in a randomized controlled trial. Objectives: To determine and compare responsiveness and minimal clinically important change of the modified Constant score (CS) and the Oxford Shoulder Score (OSS). Background: The OSS and the CS are commonly used to assess shoulder outcomes. However, few studies have evaluated the measurement properties of the OSS and CS in terms of responsiveness and minimal clinically important change. Methods: The study included 126 patients who reported having difficulty returning to usual activities 8 to 12 weeks after arthroscopic decompression surgery for subacromial impingement syndrome. The assessment at baseline and at 3 months included the OSS, the CS, and the European Quality of Life-5 Dimensions-3 Level (EQ-5D-3L) index. Responsiveness was assessed as follows: by correlation analysis between the change scores of the OSS, CS, and EQ-5D-3L index, and the Patient Global Impression of Change (PGIC) scale; by receiver-operating-characteristic (ROC) curve analysis using the PGIC scale as an external anchor; and by effect-size statistics. Results: At 3 months, a follow-up assessment of 112 patients (89%) was conducted. The change scores of the CS and the OSS were more strongly correlated with the external anchor (PGIC scale) than the change score of the EQ-5D-3L index. The areas under the ROC curves exceeded 0.80 for both shoulder scores, with no significant differences between them, and comparable effect-size estimates were observed for the CS and the OSS. Minimal clinically important change ROC values were 6 points for the OSS and 11 points for the CS, with upper 95% cutoff limits of 12 and 22 points, respectively. Conclusion: The CS and the OSS were both suitable for assessing improvement after decompression surgery. J Orthop Sports Phys Ther 2015;45(8):620–625. Epub 25 Jun 2015. doi:10.2519/jospt.2015.5760

Randomized clinical trial comparing two interventions in employees sick-listed 3 to 16 weeks because of low back pain (LBP). To compare 1-year return to work (RTW), pain, disability and physical and mental health dimensions in subjects offered a hospital-based multidisciplinary intervention or a brief intervention. Previous studies in sick-listed employees with LBP have indicated efficacy of both brief and more comprehensive multidisciplinary interventions. However, it remains unknown, which is the more effective, and which elements are instrumental in furthering RTW, and improving health. The brief intervention comprised clinical examination and advice offered by a rehabilitation physician and a physiotherapist. In the multidisciplinary intervention, this intervention was supplemented with the expertise of a team and the assignment of a case manager who drew up a rehabilitation plan in collaboration with the patient and the multidisciplinary team. One-year RTW was estimated by data from a comprehensive national database of social transfer payments. Questionnaires were used to obtain baseline and 1-year data on Roland Morris disability score, LBP Rating Scale, SF36, and fear-avoidance. A total of 351 patients were included and randomized and 344 (98%) patients participated in all the consultations according to the study protocol. RTW was achieved by 125 (71.0%) participants in the multidisciplinary and 133 (76.0%) participants in the brief intervention group. The hazard ratio was 0.84 after adjustment for sex, age, smoking, compensation claims, disability score, and diagnosis (95% confidence interval [CI]: 0.65–1.08,P = 0.18). Multiple linear regression analysis displayed no differences in secondary outcomes, except for the mental health score (SF36), which was a little higher in the multidisciplinary intervention group than in the brief intervention group. Hospital-based multidisciplinary intervention may be no better than brief intervention to increase RTW and improve health in sick-listed employees with low back pain.

Background and Aim: Chronic musculoskeletal pain is common and associated with more general healthcare-seeking. However, musculoskeletal-related healthcare utilization is under-explored. This study aimed to explore, describe and profile trajectories of long-term musculoskeletal healthcare for people reporting chronic musculoskeletal pain. Methods: This exploratory prognostic cohort study combined survey and national health register data from a representative group of adult Danes reporting chronic musculoskeletal pain (N = 2929). Trajectories of long-term musculoskeletal healthcare use were generated using latent class growth analysis. Types of healthcare-seeking, individual, sociodemographic, health, belief and work-related factors were used to describe and profile identified trajectories. Results: We identified five distinct trajectories of long-term musculoskeletal healthcare utilization (low stable, low ascending, low descending, medium stable and high stable). The low stable trajectory group (no or almost no annual contacts) represented 39% of the sample, whereas the high stable trajectory group (consistent high number of annual contacts) represented 8%. Most healthcare-seeking was in primary healthcare settings (GP/physiotherapy/chiropractor). Opioid consumption was primarily in the high stable trajectory group, and surgery was rare. There were statistically significant differences across the five trajectory groups in individual, sociodemographic, health, belief and work-related profiles. Conclusion: Long-term use of musculoskeletal healthcare services varied in this chronic musculoskeletal pain population. Almost 40% coped without seeking care, whereas 8% had consistent high use of healthcare services. Chronic musculoskeletal pain was mostly managed in primary care settings, which aligns with musculoskeletal guidelines, as did the use of pain medication and surgery. People with different musculoskeletal healthcare trajectories had different individual, sociodemographic, health, belief and work-related profiles.
