Effectiveness of spinal cord injury rehabilitation.

As in other areas of rehabilitation, relatively small numbers and diversity--both of condition and of patients' goals--hinder the assimilation of robust evidence for the effectiveness of rehabilitation. Patients with spinal cord injury (SCI) tend to be gathered together in a small number of regional services, each with their own philosophy and each with different attitudes to outcome measurement, and thus collection of the existing trials for meta-analysis is problematic. The marked improvement in outcome from SCI that has occurred with the development of specialist rehabilitation programmes argues strongly for the effectiveness of rehabilitation, and we have progressed beyond the point where randomized controlled trials that deny a group such intervention could be considered ethical. Current research is aimed at teasing apart the aspects of different care models that are most effective, or the evidence for the usefulness of interventions for control of symptoms such as spasticity and pain. This evidence is reviewed and discussed.
