The electrogoniometric method was used to measure 3 planes of knee motion in 30 normal men performing activities of daily living. The activities of daily living included going up and down stairs, sitting in a chair, tying a shoe, and lifting an object with and without instruction in proper body mechanics. Femoral and tibial-foot segment lengths were correlated with the amount of motion in the sagittal plane required for a given activity. Results indicate varying amounts of motion were required for different activities and different methods of performing the same activity. The composite view suggests that more than 90 degrees (1.57 rad) of knee flexion is required for the activities of daily living considered in this study. There is a positive correlation of femoral and tibial-foot segment lengths with the amount of knee motion required for sitting, tying a shoe, and lifting an object with instruction.
