Twelve male patients with spinal cord injury were studied. The purpose of this study was to determine if ulnar nerve damage occurs in patients with spinal cord injury who are wheelchair bound and if so at which segment of the ulnar nerve. The results showed significant drop in ulnar nerve conduction velocity in both segments, mid-arm to below elbow and below to the wrist. There was no significant difference between quadriplegic and paraplegic. No significant correlation was found between ulnar nerve impairment and the duration of spinal cord injury.
