Abstract: Disclosed is a gait start intention detection device for detecting a walker's gait start intention, including a plurality of left foot sole sensor units and a plurality of right foot sole sensor units to measure ground reaction force signals generated from foot soles while walking, and a calculation unit to receive and calculate the left ground reaction force signal and the right ground reaction force signal, wherein the calculation unit calculates a center of pressure (COP) location in a walking direction and a direction perpendicular to the walking direction using data of the ground reaction force signal measured from each sensor unit, and detects the walkers gait start intention when a ground reaction force of a swing foot heel of the walker increases, and at the same time, the COP location moves to a rear side of the walker.

Abstract: The training apparatus according to an embodiment includes: a support unit; a guide unit fixed on the support unit and including rails which extend in a front-rear direction; a sliding unit which is movable in the front-rear direction along the rails of the guide unit; a pillar-shaped rotation axis fixed on the support unit; a footrest unit which supports a user's foot; a lower support formed below the footrest unit; and a connection rotating unit formed below the footrest unit and connected to the rotation axis of the support unit through insertion to allow the footrest unit to rotate around the rotation axis. A plurality of springs installed inward from two sidewalls of the sliding unit is configured to come into contact with the lower support of the footrest unit and apply pressure from two sides when the footrest unit rotates.
