Twenty Adult traumatic paraplegics with neurologically complete lesions between C8 and T12 have ambulated using a ParaWalker (adult hip guidance orthosis), for a minimum of 6 months at home. At follow up, on average 20 months from the date of issue of the orthosis, 17 patients (85%) were still regularly using their ParaWalker. Patients achieved independent use of the orthosis and low energy ambulation both indoors and outdoors on a variety of surfaces. A new classification of adult paraplegic ambulation using an orthosis is described.
