XFT-2001 Foot Drop System is a functional electrical stimulator which is intended to provide ankle dorsiflexion for patients with foot drop following an upper motor neuron injury or disease (such as stroke, traumatic brain injury, multiple sclerosis, cerebral palsy or incomplete spinal cord injuries). During the swing phase of gait, the XFT-2001 Foot Drop System electrically stimulates muscles in the affected leg to provide dorsiflexion of the foot; Thus, it may improve the patient's gait. The XFT-2001 Foot Drop System may also facilitate muscle re-education, prevent/retard disuse atrophy, maintain or increase joint range of motion and increase local blood flow.
