An enriched environment increases activity in stroke patients undergoing rehabilitation in a mixed rehabilitation...

An enriched environment (EE) facilitates physical, cognitive and social activity in animal models of stroke. The aim of this pilot study was to determine whether enriching the environment of a mixed rehabilitation unit increased stroke patient activity.

A non- randomized controlled trial was conducted. Direct observation was used to determine the difference in change in physical, cognitive, social or any activity over 2 weeks in patients exposed to an enriched versus non-enriched environment.

Stroke patients in the EE (n = 15) were 1.2 (95% CI 1.0-1.4) times more likely to be engaged in any activity compared with those in a non-enriched environment (n = 14). They were 1.7 (95% CI 1.1-2.5) times more likely to be engaged in cognitive activities, 1.2 (95% CI 1.0-1.5) times more likely to be engaged in social activities, 0.7 (95% CI 0.6-0.9) times as likely to be inactive and alone and 0.5 (95% CI 0.4-0.7) times as likely to be asleep than patients without enrichment.

This preliminary trial suggests that the comprehensive model of enrichment developed for use in a rehabilitation unit was effective in increasing activity in stroke patients and reducing time spent inactive and alone.
