Abstract:
ObjectiveTo determine the test-retest reliability of lower extremities response time of functional squat system tests in patients with knee osteoarthritis.MethodsThirty patients who met the inclusion criteria of knee osteoarthritis were carried out lower extremities response time measurement twice within 1 week by the same tester. Intra-class correlation coefficients with 95% confidence intervals was calculated.ResultsThe intra-class correlation coefficient of the total response time and the reaction time ranged from 0-44 to 0-62 (P<0-05 or P<0-001). ConclusionLower extremities response time of functional squat system tests has an acceptable test-retest reliability in patients with knee osteoarthritis. It can better reflect their reaction capability and can appropriately reflect the adaptation and plasticity of lower extremities muscles' desired action to meet stimulation in patients with knee osteoarthritis.
