Restoring independence in performing daily functions is the main goal following spinal cord injury. Different rehabilitation methods aim to permit the paraplegic some degree of independence. One such method is the application of functional electrical stimulation (FES) to the muscles of the lower limbs. In this paper we describe a system for the functional activation of spinal cord-injured patients. The system combines a microcomputer-controlled electrical stimulator and an instrumented walker. It enables the following functions: strengthening exercises for the muscles of the lower limbs; standing up from the sitting position; maintaining the standing position; and performing reciprocate gait while using a specially adapted walker. These functions can be accomplished by the user, without any external assistance. The system components and function are described.
