MORE The AutoAmbulator is a way to help patients who have gait problems -- from multiple sclerosis, a stroke, or a spinal cord injury. The AutoAmbulator combines a treadmill, a suspension system, two robotic arms and a computer......The suspension system keeps the patient in an upright position and governs how much of his weight is on the treadmill. What sets the AutoAmbulator apart are the robotic arms, which move the patient's legs in a normal gait, work that normally would be done by the physical therapist.
