Long-term use of computerized bicycle ergometry for spinal cord injured subjects.

Twenty-eight spinal cord injured subjects who participated in an electrical stimulation bicycle ergometry home program were surveyed to determine perceived benefits, home exercise adherence, and predictors of continued home exercise with electrical stimulation. Subjects were classified as users or nonusers depending upon if they used the electrical stimulation ergometry on a regular basis in the home during the past four months. Nineteen subjects qualified as users and nine were nonusers. Ninety-five percent of the users cycled at least twice per week whereas the majority of the nonusers stopped regular home exercise within one month postclinic discharge. All subjects generally perceived increases in muscle bulk and endurance. Users and nonusers perceived inconsistent results related to spasticity. Minimal effects were noted with neurogenic pain and swelling. Adherence to the home exercise program was significantly related to sex of subject and pre-injury exercise habits. Results are discussed in relation to the costs and benefits of electrical stimulation bicycle ergometry in the home.
