Study to Elucidate Functional Compensatory Movements of Lower Limbs During Gait with the Roll-over Shapes Brace and Adaptability of Clinical Application

Abstract

The purpose of the study analyzes an electromyogram when I walked in Roll-over shapes(ROS) brace and is to inspect function compensation characteristics of lower limbs. The object was 12 normal women, and the method changed gait speed on the treadmill into three phases (4.5km/h, 3.5km/h, 2.0km/h)．In addition, the ROS brace compared it by four settings (15%, 21%, 27%, 33%)．The measurement of the muscle activity was tibialis anterior muscle, gastrocnemius, rectus femoris muscle, semitendinosus, and, in results, the ROS brace, tibialis anterior muscle and a gastrocnemial muscle contraction were seen in terminal stance. In addition, a muscular active mass of a ROS brace increased, and the muscle activity of rectus femoris muscle and the semitendinosus was similar with a normal gait, and the gait that was a low speed of ,R27% brace was similar with the shoes. In ROS brace, locomotor compensation was carried out with tibialis anterior muscle and gastrocnemius than these results. In addition, it was suggested that an application possibility was high in R27% brace.
