“…The mean score of 29.4 (SD ± 13.8) in our study population indicated a more severe level of disability compared with these populations. The level of disability in our study population is comparable to other studies of patients with shoulder impingement syndrome [53,54]. …”

BackgroundPatient-rated outcome measures (PROMs) are an important part of clinical decision-making in rehabilitation of patients with shoulder pain. The Disabilities of Arm, Shoulder and Hand (DASH) questionnaire was designed to measure physical disability and symptoms in patients with musculoskeletal disorders of the upper extremity and is one the most commonly used outcome measures for patients with shoulder pain. The purpose of this study was to investigate the reliability and validity of the Norwegian version of the DASH in patients with shoulder impingement syndrome.MethodsSixty-three patients diagnosed with shoulder impingement syndrome at an orthopaedic outpatient clinic were included in the study. Internal consistency of the DASH was evaluated by the Cronbach’s alpha and item-to-total correlations. Test-retest reliability was analyzed by the intraclass correlation coefficient (ICC) and limits of agreement (LoA) according to the Bland Altman method. Standard error of measurement (SEM) and minimally detectable change (MDC) were calculated for the total DASH score. Construct validity was evaluated by testing six a priori hypotheses for the Pearson’s correlation coefficient between the DASH and the Shoulder Pain and Disability Index (SPADI), the 36-item Short Form Health Survey (SF-36) and a Numeric Pain Rating Scale (NPRS).ResultsReliability: Cronbach’s alpha of the DASH was 0.93 and item-to-total correlations ranged from 0.36 to 0.81. ICC was 0.89. The 95 percent LoA was calculated to be between -11.9 and 14.1. SEM was 4.7 and MDC 13.1. Construct validity: Eighty-three percent of the a priori hypotheses of correlation were confirmed. The DASH showed a high positive correlation of 0.75 with the SPADI, a negative moderate correlation of -0.48 to -0.62 with physical functioning, bodily pain and physical component summary of the SF-36 and a moderate positive correlation of 0.58 with the NPRS. DASH correlated higher with the physical component summary than with the mental component summary of the SF-36.ConclusionsThe Norwegian version of the DASH is a reliable and valid outcome measure for patients with shoulder impingement syndrome.

“…The sample size is calculated to test the superiority of the PR protocol over the UC protocol in the assessment of change in the WORC physical symptoms subscale at week 12 (primary outcome) [75]. With 41 patients per group, the study will have 80% power assuming the expected group difference in the mean changes from baseline is 12 points, corresponding to the suggested minimum clinical relevant difference [47], the common standard deviation is 20 (0–100 scale) [75] and a significance level of 5%.…”

BackgroundRotator cuff tear is a common cause of shoulder disability and results in patients predominantly complaining of pain and loss of motion and strength. Traumatic rotator cuff tears are typically managed surgically followed by ~ 20 weeks of rehabilitation. However, the timing and intensity of the postoperative rehabilitation strategy required to reach an optimal clinical outcome is unknown. Early controlled and gradually increased tendon loading has been suggested to positively influence tendon healing and recovery. The aim of this trial is therefore to examine the effect of a progressive rehabilitation strategy on pain, physical function and quality of life compared to usual care (that limits tendon loading in the early postoperative phase) in patients who have a rotator cuff repair of a traumatic tear.MethodsThe current study is a randomized, controlled, outcome-assessor blinded, multicenter, superiority trial with a two-group paralleled design. A total of 100 patients with surgically repaired traumatic rotator cuff tears will be recruited from up to three orthopedic departments in Denmark, and randomized to either a progressive early passive and active movement program or a limited early passive movement program (usual care). The primary outcome measure will be the change from pre-surgery to 12 weeks post-surgery in the Western Ontario Rotator Cuff Index questionnaire. Secondary outcomes include the Disabilities Arm, Shoulder and Hand questionnaire (DASH), range of motion, strength and tendon healing characteristics from ultrasound measurements at 12 months follow up.DiscussionWe hypothesized that patients who receive the progressive rehabilitation strategy will benefit more with respect to pain reduction, physical function and quality of life than those who receive care as usual. If this is confirmed our study can be used clinically to enhance the recovery of patients with traumatic rotator cuff tear.Trial registrationClinicalTrials.gov, NCT02969135.

“…If a response is lacking in any subscale, the lost item score can be compensated for by the mean of the other items in the subscale. Nevertheless, losses of more than two items in a subscale cannot be compensated, they must be listed as incomplete [32]. …”

BackgroundThe Western Ontario Rotator Cuff Index (WORC) is a scale designed to evaluate the impact of rotator cuff (RC) disorders on patients’ general quality of life. Our study aims to adapt the WORC for Chinese patients and to assess its reliability, validity, and responsiveness in Chinese patients with RC disorders.MethodsFirst, we developed the Chinese version of the WORC (C-WORC) in a five-step procedure of translation and cross-cultural adaptation. Next, the recruiting patients finished all three rounds of scales of the C-WORC, the Medical Outcomes Study Short-Form 36 (SF-36), and the Oxford Shoulder score (OSS). Then we calculated Cronbach’s alpha, the intra-class correlation coefficient (ICC), Pearson’s or Spearman’s correlation coefficient (r or r s), the effect size (ES), and the standardized response mean (SRM) to evaluate the reliability, validity and responsiveness of the C-WORC, respectively.ResultsOverall, 124 patients with RC disorders successfully completed the first two rounds of the scales, and 108 patients completed the last round of the scales. Good or excellent internal consistency (Cronbach’s alpha = 0.872–0.954) was found in the overall scale and subscales of C-WORC, as well as good or excellent test-retest reliability (ICC = 0.828–0.961). Moderate or good correlations (r/r s = 0.472–0.787) were obtained between the physical subscales of the C-WORC and the OSS and the physical subscales of SF-36; the results were also obtained for the emotions subscale of the C-WORC and the mental subscales of SF-36 (r/r s = 0.520–0.713), which, adequately illustrated that good validity was included in the C-WORC. In addition, good responsiveness was also observed in the overall scale and subscales of the C-WORC (ES = 1.57–2.27, SRM = 1.52–2.28).ConclusionsThe C-WORC scale is reliable, valid and responsible for the evaluation of Chinese-speaking patients with RC disorders and would be an effective instrument.
