Abstract
A device has a valve (21) activated by hydraulic fluid in opposition to a resilient restoring element (27) and blocking off an outlet in the bottom of a cylinder ( 3 ) when the fluid, responsive to being compressed by a piston (5), exerts a specified pressure subsequent to an involuntary movement on the part of a femoral amputee wearing the device so as to correct the gait of the amputee.
