[Evaluating the reliability, validity and responsiveness of the german short musculoskeletal function assessment questionnaire, SMFA-D, in inpatient rehabilitation of patients with conservative treatment for hip osteoarthritis].

Background: Modern patient based outcome measures like the SMFA-D (German Short Musculoskeletal Function Assessment Questionnaire) are able to detect the impairment and functional capacity of patients with musculoskeletal extremity disorders. The SMFA-D was successfully evaluated in several cohorts treated operatively for osteoarthritis of the knee and hip, rotator cuff tears and rheumatoid arthritis. The aim of the present study was the evaluation of the SMFA-D in patients with conservative treatment for hip osteoarthritis.
