Group A (n=12) will receive 18 alternating visits of conventional physical therapy and powered exoskeleton gait training with a wearable robotic powered exoskeleton , three times a week for approximately 6 weeks.

Group B (n=12) will receive 18 visits of powered exoskeleton only, three times a week for approximately 6 weeks.

Group C (n=12) will receive 18 visits of physical therapy, three times a week for approximately 6 weeks. Upon completion of the data collection portion of the study, group C will receive 9 sessions, three times a week for approximately three weeks of powered exoskeleton therapy. Data will not be collected or reported during this phase, but but may be retained for future approved use.

Subject sits in a standard armchair and stands, and at a self-selected walking speed, walks 3 meters, turns, and walks back to the chair, and sits down. They will be timed. Takes three minutes to administer.

Subjects will be timed as they walk a known distance of 10 meters to determine his self-selected walking velocity (distance/time). They will be timed. Takes five minutes to administer.

This test measures distance walked in six minutes to assess a patient's physical endurance. They walk at a self-selected speed and will be timed. This test takes approximately 10 minutes to administer

The Berg balance test is a reliable measure for predicting risk for fall. This 14-item test measures static and dynamic balance measures and takes 15-20 minutes to administer

This has been shown to be an effective tool for assessing the psychological impact of balance impairment and falls and measuring an individual's balance confidence. Using a Likert scale, this self-administered test evaluates a person's confidence in balance over various activities. This 16-question test takes 5 to 10 minutes to complete.
