To regain the locomotive ability in daily living, many prosthetic knee joint units have been developed for transfemoral amputees. Until now, several prosthetic knees have been developed for stair ascent as commercial products, such as Genium® (Otto Bock, GmbH). Such microprocessor controlled knees are multifunctional, and they are able to realize many activities of daily living for transfemoral amputees. However, those prosthetic knees are very expensive, so they have not been widely adopted. The purpose of the present study was to develop a control method for transfemoral prosthetic knees that deals with such variation of gait pattern within subjects. To evaluate the newly proposed algorithm with the new threshold values, the database of the level walking was used. As the result of the evaluation, the accuracies of the gate detection for the stance phase and swing phase were both increased. However, the accuracy for the stance phase of stair ascending could not be enough evaluated because of absence of a database for stair ascent.
