Résumé : | Background General ankle-foot orthosis (AFO) cannot be flexibly adjusted to volumetric change in the lower leg because the molding is custom-fit. Thus, we developed a flexible assistive device called elastic neutral AFO (EN-AFO) to help stroke patients hold a neutral ankle position. The purpose of this study was to investigate the effects of EN-AFO and improve gait patterns in stroke patients with rearfoot varus deformity. Methods Fifteen stroke patients with a varus deformity of the foot performed a walking test with and without the use of EN-AFO. Kinematic data were measured with a 3D motion analysis system with inertial measurement unit (IMU) sensors. Results In the stance phase, maximal pelvic tilt and maximal ankle dorsiflexion in the affected side changed, and maximal and minimal pelvic tilts and maximal hip abduction in the less-affected limb effectively changed, as well. During the swing phase, minimal pelvic tilt and minimal ankle abduction in the affective limb greatly changed; particularly, the reduction of maximal ankle inversion was significantly cleared. Conclusions The EN-AFO was effective in controlling the tendency of foot inversion in patients with varus deformities. This is suitable for gait training, as it can adjust the orthosis stiffness according to the foot condition. |
