Rehabilitation for stroke: a review

Survivors of stroke are often left with severe mental and physical disabilities, which create a major social and economic burden. Many investigators have attempted to assess the role of rehabilitation in reducing such disability. Few controlled studies provide accurate assessment and documentation of benefit. Because of the presence of multiple variables and inadequate measures of outcome, it is difficult to design studies evaluating the effectiveness of rehabilitation for stroke. It is unclear how early rehabilitation should begin and what aspects of rehabilitation are important. Intensive rehabilitation is an expensive and limited resource; thus, the ability to identify the subgroup of patients with stroke who are likely to benefit is a critical issue. Although preliminary guidelines for the selection of patients who are appropriate for rehabilitation are given, no uniform criteria reliably differentiate patients who need rehabilitation from those who will recover spontaneously or do poorly. Controlled studies in the practice of rehabilitation for stroke will provide much useful information for patient management.
