WalkAide is a medical device that improves the walking ability of people suffering from dropfoot. This condition is caused by weakness or paralysis of the muscles involved in lifting the front part of the foot. People with multiple sclerosis (MS), spinal cord injuries, traumatic brain injuries, cerebral palsy or have suffered a stroke may experience the effects of this condition. WalkAide uses functional electrical stimulation to restore the typical nerve-to-muscle signals in the leg and foot, effectively lifting the foot at the appropriate time during the gait cycle. The resulting movement is a smoother, safer stepping motion. Users are able to walk faster and for longer distances with less fatigue.
How It Works
WalkAide is a battery-operated, single-channel electrical stimulator that utilizes a "Tilt Sensor" to control stimulation during normal gait. By applying low level electrical currents directly to a motor nerve in the leg, the WalkAide instructs the muscle to flex the foot at the appropriate time in the gait cycle so the patient can walk more normally. Contrary to traditional therapies that require hours in hospitals or rehabilitation facilities, the WalkAide is portable and wireless. About the size of a cell phone, the device is worn around the leg, just below the knee.
