| Research Abstract |
Rehabilitation is very important in preventing an increase of bedridden patients and improving their impairments. Information on the joint moment or muscle action of patients is very useful for doctor or PT to judge what kind of rehabilitation menu is optimum for each patient. The integration of three dimensional motion measurement with multi-camera system and ground reaction measurement with forte plate has been widely used. They apply inverse dynamics to estimate joint moment . However such a method needs sizable work space and it is very expensive for daily rehabilitation.
In this research project, a new wearable 3-dimentinal ground reaction force sensor and wearable motion sensor are developed. A parallel type 6-axial load sell, a 3-axial load cell and a motion sensor are mounted in the shoes of patient which is the wearable ground reaction sensor system. Reaction force in local coordinate is transformed to the rectangular coordinate. By using this new wearable reaction force sensor and wearable motion sensor attached to the human lower limb, estimation method of joint moment of human lower limb is developed. Gait analysis is carried out and experimental results of the proposed methods on ground reaction force and joint moment of the lower limb compare well with those by using the conventional method.
