Physiotherapist-supervised exercises versus unsupervised home-based exercises after nonsurgically treated proximal humerus fracture: a multicenter randomized controlled trial.

BACKGROUND: Proximal humerus fracture (PHF) is a common fragility fracture in older adults and can have a substantial impact on upper limb function. Although most patients with PHF can be treated nonsurgically, it is unknown whether older adults benefit from supervised exercise therapy after PHF. Therefore, the objective of this trial was to investigate whether 10 weeks of physiotherapist-supervised exercises once a week were superior to 10 weeks of unsupervised home-based exercises in older adults with a nonsurgically treated displaced 2-part PHF. METHODS: This was designed as an assessor-blinded, prospective, randomized controlled trial and took place in 3 Nordic countries. In total, 72 patients (≥60 years) with nonsurgically treated displaced 2-part PHF were randomized to either physiotherapist-supervised exercises once a week for 10 weeks, combined with daily home-based exercises, or to 10 weeks of daily unsupervised home-based exercises. The primary outcome measure was the Disability of the Arm, Shoulder, and Hand (DASH) with a primary endpoint at 3 months. Secondary outcomes were DASH (at 12 months), Constant-Murley Score, the 15D-instrument, Visual Analog Scale, General Self-Efficacy Scale, and Pain Catastrophizing Scale, with follow-up visits after 3 and 12 months. Non-union and patient death within 3 months were counted as complications. RESULTS: The mean age of the patients in both groups was 72 years. At 3 months follow-up, the mean DASH score in the supervised group was 25.9 (SD 16.0) compared to 22.4 (SD 18.9) in the unsupervised group. The mean between-group difference (3.5, 95% CI -5.0 to 12.5) was not clinically relevant. None of the secondary outcome measures presented any clinically relevant or statistically significant between-group differences at 3 or 12 months follow-up. One patient in the supervised group and 3 in the unsupervised group were diagnosed with non-union. One patient from each group died before 3 months follow-up. CONCLUSIONS: This trial provides no evidence that supervised exercises are superior to unsupervised home-based exercises in improving functional outcome or health-related quality of life in older patients with a nonsurgically treated 2-part PHF. Further, our results suggest that most older adults with a nonsurgically treated 2-part PHF can perform home-based exercises without the supervision of a physiotherapist.

Shoulder patients in primary and specialist health care. A cross-sectional study.

OBJECTIVES: Shoulder pain is a prevalent problem and has a considerable impact on the use of primary and specialist health care in Norway. It is important to improve short-term recovery and reduce long-term consequences regarding pain and disability, the high costs of treatment and the amount of sick-leave. Treatment for non-specific shoulder pain is mainly non-operative. The aims of this study were to investigate if there are differences in main characteristics, pain and disability (SPADI-score) and psycho-social factors between patients in primary and specialist health care. METHODS: This cross-sectional study included patients consulting physiotherapy in primary health care and patients at an outpatient clinic in specialist health care. Well-known and tested questionnaires for these populations were used and variables were divided into clinical, sociodemographic, psycho-social, and shoulder pain and disability. Descriptive statistics were applied. Two-sample t-test and linear regression were used for continuous data whereas chi-square tests and logistic regression were applied to test differences in categorical data between the two study populations. RESULTS: Two hundred and 36 patients were recruited from primary health care (FYSIOPRIM, Physiotherapy In Primary Care) and 167 from specialist health care. Patients in primary health care reported less regular use of pain medication (30.7 vs. 61.3%) and fewer patients had symptom duration >12 months (41.9 vs. 51.0%). Furthermore, they reported lower pain intensity, less shoulder pain and disability (SPADI-score), lower scores on psycho-social factors, but higher on expectations of recovery. CONCLUSIONS: Patients with shoulder pain treated in primary health care and in specialist health care are different according to factors such as duration of symptoms, pain and disability, and some of the psycho-social variables. However, the differences are small and the variations within the two study samples is large. Patients treated in primary health care seemed to be less affected and to have higher expectations concerning their recovery. However, based on our results we may question why many patients are referred to specialist health care rather than continuing treatment in primary health care.

Patients with shoulder pain referred to specialist care; treatment, predictors of pain and disability, emotional distress, main symptoms and sick-leave: a cohort study with a six-months follow-up.

Objectives Recommendations for referral of patients with shoulder pain from primary to specialist care are mainly clinical. Several patients are referred without meeting these criteria for referral, whereas some are referred for a second opinion although surgery is not recommended. The aims of this study were to describe a shoulder pain cohort in specialist healthcare according to demographic data, clinical, and psychological factors; evaluate changes in pain and disability, distress and main symptoms from baseline to six-month follow-up; and to assess predictors of pain and disability, changes in the main symptoms and sick-leave at six-months. Results were compared to previous randomised trials conducted at the same clinic in patients with subacromial shoulder pain. Methods This prospective study included 167 patients from an outpatient clinic in specialist healthcare with shoulder pain for more than 6 weeks. Clinical (pain duration, intensity, pain sites), sociodemographic (age, gender, educational level, work status) and psychological variables (emotional distress (HSCL-10), fear of pain, screening of "yellow flags", health-related quality of life) were collected. Shoulder pain and disability (SPADI-score) were assessed and the patients were asked about their outcome expectation and to predict their status of their shoulder problem the next month. They underwent a clinical interview, a clinical assessment of shoulder function and orthopaedic tests for diagnostic purposes. After six months they received a questionnaire with main variables. Results Of the 167 patients (55% women), 50% had symptoms for more than 12 months and 37 (22%) were on sick-leave. Characteristics were in general comparable to patients previously included in clinical trials at the same department. The SPADI-score was 46 (23) points. Mean emotional distress was within the normal range (1.7 (SD 0.6)). More than 80% had received treatment before, mainly physiotherapy in addition to the GPs treatment. One hundred and thirty-seven patients (82%) were re-referred to physiotherapy, 74 (44%) in the outpatient clinic specialist healthcare, and 63 (38%) in primary care. One hundred and eighteen (71%) answered the follow-up questionnaire. Mean change in SPADI-score was 10.5 points (95% CI (6.5-14.5)), and 29% of the patients improved more than the smallest detectable difference (SDD). The percentage sick-listed was 19.5%, and mean change in main symptoms (-9 to +9) was 3.4 (SD 3.9). The subgroup of patients receiving physiotherapy in outpatient specialist care did not show any significant change in the main variables. The prediction models suggested that a lower level of education, more fear of pain and a high baseline SPADI-score, predicted a higher SPADI-score at follow-up. A high baseline HSCL-10 score was the only significant predictor for a high HSCL-10 score. At follow-up, less pain at rest predicted more change in main symptoms and more yellow flags (a higher score on the Örebro screening test) predicted sick-leave. Conclusions Within the limitations of a cohort study, patients with persistent shoulder pain referred to an outpatient specialist clinic had similar baseline characteristics but shorter treatment duration, inferior clinical results and predictors somewhat different compared with previous clinical trials conducted at the same clinic. The study raises some questions about the effectiveness of the routines in daily clinical practice, the selection of patients, the treatment duration and content.

Novel approach towards musculoskeletal phenotypes.

BACKGROUND: The multidimensional array of clinical features and prognostic factors makes it difficult to optimize management within the heterogeneity of patients with common musculoskeletal pain. This study aimed to identify phenotypes across prognostic factors and musculoskeletal complaints. Concurrent and external validity were assessed against an established instrument and a new sample, respectively, and treatment outcome was described. METHODS: We conducted a longitudinal observational study of 435 patients (aged 18-67 years) seeking treatment for nonspecific complaints in the neck, shoulder, low back or multisite/complex pain in primary health care physiotherapy in Norway. Latent class analysis was used to identify phenotypes based on 11 common prognostic factors within four biopsychosocial domains; pain, beliefs and thoughts, psychological and activity and lifestyle. RESULTS: Five distinct phenotypes were identified. Phenotype 1 (n = 77, 17.7%) and 2 (n = 142, 32.6%) were characterized by the lowest scores across all biopsychosocial domains. Phenotype 2 showed somewhat higher levels of symptoms across the biopsychosocial domains. Phenotype 3 (n = 89, 20.5%) and 4 (n = 78, 17.9%) were more affected across all domains, but phenotype 3 and 4 had opposite patterns in the psychological and pain domains. Phenotype 5 (n = 49, 11.3%) were characterized by worse symptoms across all domains, indicating a complex phenotype. The identified phenotypes had good external and concurrent validity, also differentiating for the phenotypes in function and health-related quality of life outcome at 3-month follow-up. CONCLUSION: The phenotypes may inform the development of targeted interventions aimed at improving the treatment efficiency in patients with common musculoskeletal disorders. SIGNIFICANCE: This observational prospective study identified five distinct and clinically meaningful phenotypes based on biopsychosocial prognostic factors across common musculoskeletal pain. These phenotypes were independent of primary pain location, showed good external validity, and clear variation in treatment outcome. The findings are particularly valuable as they describe the heterogeneity of patients with musculoskeletal pain and points to a need for more targeted interventions in common musculoskeletal disorders to improve treatment outcome.

Associations between shoulder pain and functioning on the ICF checklist and the disabilities of the arm, shoulder, and hand scale - a cross-sectional study.

Purpose: The association between patients' shoulder pain and functioning according to the International Classification of Functioning, Disability, and Health (ICF), and outcome on a condition specific patient reported outcome measure (PROM), has not been studied. The aim was to investigate how the most common problems on the ICF checklist were associated with shoulder function and disability.Materials and methods: In a cross-sectional design 164 patients ≥ 18 years with chronic shoulder pain were included. The ICF checklist, the Disability of the Arm, Shoulder, and Hand (DASH) outcome measure and the Self-Report Comorbidity Questionnaire were used. A hierarchical regression model tested categories for functioning on the ICF checklist associated with disability on the DASH.Results: Mean age was 46.5 years, 54% were women. 85% had had the shoulder pain longer than 6 months. Mean DASH score was 33.2 points (SD 17.1). Adjusted R2 was 0.67. Older age, being woman and having a lower education explained 22% of the variance on the DASH. The body functions bodily pain, mobility of joints and energy and drive function explained 30% of the variance, and the activities and participation problems lifting and carrying objects, washing oneself and recreation and leisure explained an additional 13%.Conclusions: The shoulder disability was multi-dimensional and comprised body functions and activities and participation. And 67% of the variance in the DASH score was explained.Implications for rehabilitationPersistent shoulder pain results in multi-dimensional disability calling for a broader assessment of function.A biopsychosocial approach to shoulder pain and disability is recommended.Functioning assessed on the ICF checklist can be applied in the assessment of chronic shoulder pain as it contributes to the understanding of self-reported disability on a region specific outcome measure.

One year results of a randomized controlled trial on radial Extracorporeal Shock Wave Treatment, with predictors of pain, disability and return to work in patients with subacromial pain syndrome.

BACKGROUND: Radial Extracorporeal Shock Wave Therapy (rESWT) is increasingly used to treat patients with subacromial pain syndrome despite conflicting evidence of its effectiveness. Better knowledge regarding prognostic factors may contribute to the improvement in treatment and prognosis for the patients. AIM: The first aim of this study was to evaluate the effect of rESWT in addition to supervised exercises in patients with subacromial pain syndrome after one year. The second aim was to identify predictors of pain and disability and work status after one year in this patient group. DESIGN: A randomized, double-blind, sham-controlled trial. SETTING: An outpatient shoulder clinic of a University hospital. METHODS: Patients aged 25 to 70 years, with subacromial pain syndrome lasting at least three months were included and randomly assigned to receive either rESWT and supervised exercises or sham rESWT and supervised exercises. The Shoulder Pain and Disability Index (SPADI) and work status were assessed after one year. RESULTS: We screened 265 patients and enrolled 143; 74 were allocated to receive sham rESWT and exercises, and 69 were allocated to receive rESWT and exercises. After one year, no differences were found for the SPADI Score (mean difference -1.6, 95% confidence interval (CI) -10.2 to 7.0, P=0.71). Subgroup analysis of patients with calcification in the rotator cuff demonstrated no significant additional effect of rESWT to supervised exercises (mean difference -6.3, 95% CI -22.4 to 9.8, P=0.44). Marital status (single), frequent use of pain medication, not working at baseline, negative outcome expectations, low self-reported general health status and few supervised exercise sessions predicted a poor outcome on SPADI after one year. CONCLUSIONS: Radial ESWT was not superior to sham rESWT in addition to supervised exercises in the long term for patients with subacromial pain syndrome. The identified predictors for pain, disability and work should be assessed in future studies and addressed by clinicians in order to improve the effectiveness of supervised exercises. CLINICAL REHABILITATION IMPACT: Radial ESWT should not be recommended for patients with subacromial pain syndrome. Clinicians should assess patient`s outcome expectations, and if possible reduce the use of pain medication and sick leave in this patient group.

Patterns of shoulder pain during a 14-year follow-up: results from a longitudinal population study in Norway.

BACKGROUND: Population studies have reported that shoulder pain is the third most frequently reported musculoskeletal pain. Long duration, pain intensity and high level of disability predict persistent complaints. The present study aimed to describe the prevalence of shoulder pain in a general population and follow this over a long period (1990 to 2004). The objective was also to describe the stability of shoulder pain and patterns of co-occurrence with neck and upper back pain. METHODS: Data were obtained from a self-reported questionnaire in a population in Ullensaker muncipality, north-east of Oslo. The Standard Nordic Questionnaire was sent in 1990, 1994 and 2004 to inhabitants belonging to six birth cohorts from 1918-20 to 1968-70. RESULTS: The 1-year prevalence of shoulder pain was 46.7% (95% CI, 44.9% to 48.6%) in 1990, 48.7% (95% CI, 46.8% to 50.5%) in 1994, and 55.2% (95% CI, 53.5% to 56.9%) in 2004. Approximately three-quarters of the persons with shoulder pain at one given time also reported shoulder pain at the next follow-up. CONCLUSIONS: Prevalence of shoulder pain during a 14-year period was high and slightly increasing. Shoulder pain was reported most frequently in co-occurrence with neck pain. Classification models should include neck pain as well as other co-occurring pain sites.
