Intersubject variability and intrasubject reliability of quantitative measures of normal human ankle mechanics were examined in fifteen young adults. Each subject was examined on two occasions to characterize passive joint dynamics, in terms of the position-stiffness relation, and active joint dynamics, in terms of the torque-stiffness relation. Quantitative, objective measures of joint properties corresponding to those in clinical use were also made for comparison purposes. Results demonstrated that measures of passive and active joint dynamics generally had an intrasubject reliability which was as good as or better than most clinical measures. Intersubject variability was somewhat larger as is the case for the clinical measures.
对15名年轻成年人的正常人体踝关节力学定量测量的个体间变异性和个体内可靠性进行了研究。每位受试者接受了两次检查，以根据位置-刚度关系表征被动关节动力学，并根据扭矩-刚度关系表征主动关节动力学。还进行了与临床使用中相应关节特性的定量、客观测量，以作比较。结果表明，被动和主动关节动力学测量的个体内可靠性通常与大多数临床测量相当或更好。个体间变异性与临床测量情况类似，略大一些。
