| Research Abstract |
The system for wheelchair seating design system that consists of three sub-systems: a seating posture analysis system, a seating posture changing system, and a propulsion analysis system has been developed. The seating posture analysis system uses video cameras, and whose analysis software to measure three dimensional co-ordinates of markers on the patients. The shape of the spine is estimated virtually and overlaid on the current camera image. Also a method to estimate the spinal shape by the finite element method (FEM) using beam elements has been developed. The seating posture changing system uses pneumatically controlled airbags installed in the wheelchair seat to change the posture of the patient aiming to generate a good posture. The function of propulsion analysis system has been enhanced to input the current seating posture from shoulder co-ordinates, calculate the position and inclination angle of pelvis and enable to estimates the imbalanced posture. The normal, anterior inclined, and slipped backward-leaning posture were evaluated by the system and the trend of variation of calculated muscular forces coincided with measured EMG..
