Abstract
Analysis of human motion is extremely important in order to obtain fundamental data for training in the field of rehabilitation. At Nagoya University we are analysing human motion by use of a micro computer to elucidate functional characteristics of the locomotion system. After the introduction of micro-computers. it has become possible to accumulate and integrate more data and process them more quickly and conveniently. Data obtained from the weight balance analyzer. large force plate and three dimensional goniometer devised by the authors are subjected to on-line processing through an AI D convertor. I. The weight-balance analY/er for the evaluation of dynamic balance ability can be used both in standing and sitting positions. A computer block-break game is integrated into the program so that training can be performed enjoyably. 2. A large serial force plate is used to detect the floor reaction force of individual legs. Three force components in the directions of X. Y and Z are transformed to resultant force. velocity. acceleration and paths of center of pressure through mathematic processing. 3. The three dimensinal goniometer describes angular changes of the hip or knee joint in the three planes during walking. In addition to flexion-cxtension. adduction-abduction and internal-external rotation can be grasped easily by this device.
