Rehabilitation therapy for patients with long-term spinal cord injuries.

Abstract

The functional effects of three types of therapy for subjects with long-term incomplete cervical spinal cord injuries were investigated. Men and women, aged 18 to 45 years, were assigned to one of four groups using a restricted randomization process. The training period was divided into two consecutive eight-week time blocks where subjects received either (1) supervised physical exercise therapy (PET), (2) neuromuscular stimulation (NMS), or (3) electromyographic (EMG) biofeedback. Group 1 received EMG biofeedback followed by PET; Group 2 received EMG biofeedback followed by NMS; Group 3 received NMS followed by PET; and Group 4 received 16 weeks of PET. Dependent measures (manual muscle tests, self-care scores, mobility measures, and voluntary EMG activity) were assessed before training, at eight weeks, and after 16 weeks of training. A significant improvement (p less than .05) across time was found on all dependent measures except voluntary EMG. No difference was found on comparisons between groups.
