Functional-Performance Deficits in Volunteers With Functional Ankle Instability.

摘要: Context: Although functional-performance tests are dynamic measures used to assess general lower body function, studies investigating these for ankle instability have yielded conflicting results.Objective: To determine if a relationship exists between measure of functional and deficits in performance.Design: A case-control study correlating subject performance on set extremity with instability.Setting: University athletic training research laboratory.Patients or Other Participants: We recruited 60 participants (43 females, 17 males, age = 22.4 +/- 4.9 years, height 169.9 9.7 cm, mass 72.6 16.3 kg; 42 injured, 18 uninjured) participate the study. Six questions were was present each participant. point added yes response produce an index that represents continuous variable instability.Main Outcome Measure(s): Four unilateral hopping this study: figure-of-8 hop, side up-down single hop. For first 3 tests, total time recorded handheld stopwatch nearest 0.01 second; hop-for-distance test, distance m. Correlations computed 4 tests.Results: No revealed hop r values -.008 .245, respectively. significant found (r .35, P
