In Taiwan as the population aging, the problems become more severe and then result in raising the social cost. According to the report from Bureau of National Health Insurance that the average annual medical treatment for osteoarthritis attains $ 1.7 billion. According to the researches from Dr. Shaw-Ruey Lyu with Dalin Tzu Chi Hospital, the severity of osteoarthritis is associated with the medial abrasion of arthrosis. Besides, the damaged pressures of all situations occur when knee angle excesses 50° of flexion. We hope to design an equipment that could monitor whether the user had overused his knee. Two accelerometers which are developed by K&Y Lab are attached on the knee brace. One accelerometer wear on the upper edge of the knee and the other on the lower edge of the knee. We want to monitor the different patterns of activity in daily life such as walking, walking up the stairs, walking down the stairs, standing and sitting, standing up from chair and walking for 8 feet. We expect that our monitor can distinguish different patterns of activity and quantify the usage of knee. Our devices can help the patients suffered from the osteoarthritis by monitoring the usage of knee.
