Abstract
The joint angles of the lower limbs are important parameters in evaluating the ability and stability of walking when training to walk or control FES gait. In this study, a simplified measurement method for lower limb joint angles that uses gyroscopes attached to the thigh, the shank and the foot is proposed. The method was examined by measuring the leg joint angles of three neurologically intact subjects when walking. The results showed a high correlation between the joint angles measured with the commercially available electric goniometer and those by the proposed method. Appropriate attachment positions of the sensors were also suggested from the experimental results. The proposed simplified measurement method for lower limb joint angles is expected to be effective for walking training or FES gait restoration at clinical sites.
