Abstract :
For the purpose of trunk stabilization in standing of paraplegic individuals induced by functional electrical stimulation (FES), the feasibility of feedback control of thorax inclination angle was examined. The sagittal and coronal inclination angles could be detected using pendulum sensors with less than three percent error. The contractile forces for the movement in an anti-gravitational environment were obtained in both the rectus abdominis and erector spinae muscles. The feasibility of the feedback control of thorax inclination angle was demonstrated
