Achievement levels in walking vary with the individual user's level of injury, learned skills, and physical condition. Distance walked will vary and increase with practice and training. Individual goals are established for each user by the physical therapist. Studies conducted in different clinical settings reported distances walked by individual users ranging from a few feet to over a mile at a time, with the average distance being around 1,450 feet (The Journal of Spinal Cord Medicine, Volume 19, Number 2).
