The Tibion Bionic Leg is a wearable, battery-powered robotic device---assists stroke patients to regain their lost gait.  The Bionic Leg is not a prosthesis.  Instead, the Bionic Leg is a rehabilitation device used under the direction of a physical therapist. It demands the patient put at least a little force on their affected leg, and computer-driven motors within the Bionic Leg provide the additional force needed to enable the patient to participate in rehab exercises.  During a period of weeks, constant repetition and slow reduction of Bionic-Leg support helps patients reprogram their brain to use alternate brain regions to control their gait.  Even patients who are 10 years post stroke have regained substantial function, at lease leaving their wheelchairs and walking with a cane.  More than a dozen rehabilitation hospitals, skilled nursing facilities and outpatient clinics are now using Tibion Bionic Leg.
