Can self-report instruments of shoulder function capture functional differences in older adults with and without a rotator cuff tear?

ABSTRACT: Rotator cuff tears (RCT) are prevalent in older individuals and may compound age-associated functional declines. Our purpose was to determine whether self-report measures of perceived functional ability are valid for older patients with RCT. Twenty five subjects participated (12M/13F; age=63.9±3.0years); 13 with RCT and 12 controls (CON). Participants completed self-report measures of shoulder function (SST, ASES, WORC) and health-related quality of life (SF-36). Isometric joint moment and range of motion (ROM) were measured at the shoulder. Relationships among functional self-reports, and between these measures and joint moment and ROM were assessed; group differences for total and subcategory scores were evaluated. There were significant correlations among self-reports (rs=0.62-0.71, p?0.02). For RCT subjects, ASES was associated with all joint moments except adduction (p?0.02); SST, ASES, and WORC were associated with abduction and external rotation ROM (p?0.04). For RCT subjects, SST and WORC were associated with SF-36 physical function subcategory scores (p?0.05). The RCT group scored worse than CON on all functional self-reports (p<0.01) and WORC and ASES subcategories (p<0.01). In conclusion, SST, ASES, and WORC demonstrate utility and discriminant validity for older individuals by distinguishing those with RCT, but this work suggests prioritizing ASES given its stronger association with functional group strength.
