Pain dominates measurements of elbow function and health status.

摘要: Background: Elbow function can be quantified with use of physician-based elbow-rating systems and health status questionnaires. Our hypothesis was that pain has a strong influence on these scores, which overwhelms the objective factors such as motion. Methods: One hundred four patients were evaluated, at minimum six months (average, forty-six months) after latest surgery for an intra-articular fracture elbow, three evaluation instruments (Mayo Performance Index [MEPI], Broberg Morrey rating system, American Shoulder Surgeons Evaluation Instrument [ASES]), upper-extremity-specific questionnaire (Disabilities Arm, Hand [DASH]), general (Short Form-36 [SF-36]). Multivariate analysis variance regression modeling used to identify account variability in scores derived measures—in other words, have strongest final score. Results: Pain alone accounted 66% MEPI 59% 57% ASES scores. Models included only slightly more (73%, 79%, respectively), those did not include 22%, 41%, 41% variability. Thirty-six percent DASH could by alone, 45% range motion. including 17% scores. Conclusions: very both physician-rated patient-rated quantitative measures elbow function. Consequently, may strongly influenced psychosocial aspects illness relationship pain, mobility undervalued. It advisable evaluate separately from ratings.
