Abstract
There has been renewed interest in the application of biofeedback for gait and posture reeducation. Electrical stimulation is one means of presenting feedback stimuli to patients and has been used with amputees to provide knowledge of gait event timing through implanted and surface stimulation of discrete anatomical regions [1, 2]. This paper briefly describes the development of a prototype stimulator and electrode array that will provide real-time electrotactile feedback to transfemoral amputees undergoing gait re-education.
