Abstract

Multivariate analysis was applied to develop systems which afford more objective and universal evaluation of joint function in the lower extremities such as the hip, knee, and ankle joint. Conventional methods have various drawbacks, such as selection of parameters, allocation of points to selected parameters, selection of indices to represent impairment of joint function as a whole, and functional evaluation in polyarticular impairment. In order to solve these problems, causative factors (pain, mobility, and stability) of the joint impairment and secondary factors such as activities of daily living (ADL) representing the overall effects of the causative factors were strictly discriminated, and only causative factors were selected to serve as functional parameters. Then, taking ADL as criterion variables and causative factors as predictor variables, multiple regression analysis was performed using 207 hips, 250 knees, and 50 ankle joints. Based on this analysis, an original system for evaluating joint function was developed.
