摘　　要：目的检验功能性蹲屈测试训练系统测量膝骨性关节炎患者下肢反应时间的重测信度。方法符合入选条件的30例膝骨性关节炎患者作为受试者,由同一测试者在1周内对受试者进行前后两次双下肢反应时间测试。应用组内相关系数进行重测信度的评价。结果受试者总反应时间和反应时间的组内相关系数为0.44～0.62(P<0.05或P<0.001)。结论功能性蹲屈测试训练系统测量膝骨性关节炎患者下肢反应时间具有中等至较好的重测信度,可以较好地反映膝骨性关节炎患者的反应能力和适度地反映下肢肌肉对刺激所需动作的适应性和可塑性。Objective To determine the test-retest reliability of lower extremities response time of functional squat system tests in patients with knee osteoarthritis.Methods Thirty 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.Results The 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）. Conclusion Lower 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.
