“…22 Previous studies have determined the responsiveness of the WOSI, though exclusively by means of distribution-based methods (SRM 30,38,43 or ES 38,43 ). To our knowledge, this is the first study that has used both distribution-based methods (ES and SRM) and an anchor-based method (ROC curve) to determine the responsiveness of the WOSI questionnaire.…”

Shoulder instability can be defined as the inability to maintain the normal position of the humeral head on the glenoid during upperlimb movements, which causes apprehension and/or pain.11 Acute traumatic anterior dislocation is the most common cause of shoulder instability. Shoulder instability may not manifest during clinical examination. The symptoms are typically intermittent and variable, thus an accurate assessment of symptoms over time and life circumstances is required to accurately portray the functional impact.Several instruments have been developed to determine the effects of shoulder instability. However, the majority of instability outcome measures consist of physician-rated questionnaires based on clinical information that does not convey T T STUDY DESIGN: Clinical measurement study. T T OBJECTIVES:To translate and cross-culturally adapt the Western Ontario Shoulder Instability Index (WOSI) into Italian, and to evaluate its measurement properties in patients with shoulder instability secondary to a first-time traumatic anterior dislocation. T T BACKGROUND:The WOSI was developed for English-speaking patients. To date, no Italian version of the WOSI exists. T T METHODS:The WOSI was cross-culturally adapted to Italian according to established guidelines. Sixty-four (16 women, 48 men) patients with unilateral shoulder anterior instability were prospectively recruited for the purposes of this study. Internal consistency, test-retest reliability, construct validity, and responsiveness of the WOSI were evaluated. T T CONCLUSION:The Italian version of the WOSI is a valid, reliable, and responsive tool that can be used to measure function in Italian-speaking patients with shoulder instability due to a first-time traumatic anterior dislocation.

“…An increasing number of questionnaires have been introduced to evaluate general shoulder function and disability [24,29]. These questionnaires range from objective measures, such as ROM [6] or muscle strength [6], to more subjective measures, such as patient satisfaction [23] or quality of life [11,35].…”

Background Psychologic distress contributes to symptom severity in patients with several musculoskeletal disorders. While numerous shoulder outcome instruments are used it is unclear whether and to what degree psychologic distress contributes to the scores. Questions/purposes We asked (1) to what degree shoulder outcome instruments reflect patients' psychologic distress, and (2) whether patients who are strongly affected by psychologic distress can be identified. Methods We prospectively evaluated 119 patients with chronic shoulder pain caused by degenerative or inflammatory disorders using the Constant-Murley scale, Simple Shoulder Test (SST), and Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. To evaluate psychologic distress, we measured depression using the Center for Epidemiologic Studies-Depression (CES-D) scale and pain anxiety using the Pain Anxiety Symptom Scale (PASS). Demographic and clinical parameters, such as pain scores, ROM, and abduction strength, also were measured. We then assessed the relative contributions made by psychologic distress and other clinical parameters to the quantitative ratings of the three shoulder outcome instruments. Results Quantitative ratings of shoulder outcome instruments correlated differently with psychologic distress. Constant-Murley scores did not correlate with psychologic measures, whereas SST scores correlated with PASS (r = 0.32) and DASH scores correlated with PASS and CES-D (r = 0.36 and r = 0.32). Psychologic distress contributed to worsening SST and DASH scores but not to Constant-Murley scores. DASH scores were more strongly influenced by pain anxiety and depression than the other two outcome instruments. Conclusions Shoulder outcome measures reflected different psychologic aspects of illness behavior, and the contributions made by psychologic distress to different shoulder outcome instruments apparently differed. Physicians should select and interpret the findings of shoulder outcome instruments properly by considering their psychologic implications.

“…Responsiveness of the SST has been more commonly evaluated in patients undergoing rotator cuff repair. 3,20,27 In contrast to sensitivity to change, which refers to the ability of an instrument to measure change in a condition regardless of whether it is relevant to the decision maker, responsiveness refers to the ability of an instrument to measure a meaningful or clinically important change in a clinical status. 16 This measurement property is conveyed using specific statistical indices.…”

Shoulder arthroplasty (SA) is an accepted means of pain relief and improving function in patients with advanced joint destruction. 35 Measures of physical impairment and selfreported function are commonly used to assess the outcomes of these procedures. Various self-reporting scales are available to measure the functional outcome of shoulder surgery, but only a few While the responsiveness of the SST has been established for rotator cuff repair, it has not been determined for patients undergoing arthroplasty.t MethoDS: Patients undergoing shoulder arthroplasty (n = 120) were evaluated prior to surgery and 6 months after. The evaluation included the SST, Disabilities of the Arm, Shoulder and Hand questionnaire, range of motion, and isometric strength. Responsiveness to change was assessed using standardized response mean (SRM), while longitudinal construct validity was evaluated using Pearson correlation. Receiver operating characteristics curves were plotted to determine clinically important difference of SST.t reSUltS: The SST and Disabilities of the Arm, Shoulder and Hand questionnaire were highly responsive (SRM, 1.70) for this population. For the assessment of impairment, range of motion (SRM, 0.64-1.03) was moderately to highly responsive, while isometric strength was minimally to moderately responsive (SRM, 0.32-0.69). The clinically important difference of the SST was established at 3.0 SST points. Pearson correlations indicated moderate associations between the change scores of the SST and the Disabilities of the Arm, Shoulder and Hand questionnaire (r = 0.49).t ConClUSionS: The SST has been previously shown to be valid and highly reliable. The present results show that the SST is also responsive following shoulder arthroplasty and that it has a clinically important difference of 3.0 SST points. This should provide confidence to clinicians who wish to use a brief shoulder-specific measure in their practice.
