Development of Assist System to Expand Voluntary of Paralyzed Foot in Acute Phase

Abstract

Rehabilitation from the acute phase to recover voluntary after stroke onset has attracted attention in recent years. We have developed a rehabilitation device that moves the paralyzed foot in the supine position and triggered by the non-paralyzed foot. In this study, we devised a rehabilitation method to expand the voluntary by changing the assist according to the voluntary of the paralyzed foot, and developed a control system that realizes the method using the existing device. In the evaluation test, a strong correlation was found between IEMG of the paralyzed foot and the assist amount, which .suggested that the proposed method was realized.
