Background and Purpose
Stroke is one of the major causes of mortality and, among survivors, disability. Physical
activity has a protective effect maybe due to a major control of risk factors, such
as hypertension, diabetes mellitus, and body weight. However, the effect of prestroke
physical activity and the poststroke functional outcomes needs clarification.
Methods
We made a systematic review of the literature to elucidate this effect through electronic
search in the MEDLINE/PubMed database. Prisma statement was used as a basis for this
systematic review and analysis of the risk of bias was made according to the Grading
of Recommendations, Assessment, Development and Evaluation. Three studies were finally
analyzed in this review.
Results
The largest of the studies (Rist et al) revealed no association between prior physical
activity and functional outcome after stroke. The second major study (Stroud et al)
showed only a slight association. Only the smallest of the 3 studies (Krarup et al)
showed a protective effect of physical activity.
Conclusions
The evidence of the protective effect of physical activity is still conflicting. Better
longitudinal studies are still needed to see the real effect of physical activity
on functional outcome after stroke.
