Passive mechanisms have been well developed to realize the safe level walk for transfemoral prosthesis users, preventing unintended knee flexion during prosthetic stance phase. However, for stair ascent, a mechanism had not existed for a long time. We previously developed the knee joint unit whose mechanism realized prosthetic knee extension using load or external force on the knee joint unit itself...
Due to the enhanced performance of recent smart-phones, some studies use them for gait analysis. An accelerometer in a smartphone can be used to measure gait parameters such as steps and walking speed. Some researchers proposed methods of measuring these parameters with a smartphone, but they did not propose methods of measuring joint angles, which are typical parameters for gait analysis. In this...
Facilities for travel are developing conveniently in recent years. A lot of people do not exercise sufficiently in daily life. As a result, the life-style related diseases like high blood pressure and obesity increase. A moderate exercise is very important to keep a healthy body for them but it is too difficult to know how to exercise moderately. Then, this paper shows the audio advising system and...
