Pilot Randomized Controlled Trial Investigating Cognitive Strategy Use to Improve Goal Performance After Stroke

OBJECTIVE. The authors compared changes in client performance on three goals poststroke after the Cognitive Orientation to daily Occupational Performance (CO-OP) intervention or standard occupational therapy (SOT) to determine the magnitude and direction of change. METHOD. Eight people living in the community following a stroke were randomly assigned to receive CO-OP (n = 4) or SOT (n = 4). CO OP is a 10-session, cognitive-oriented approach to improving performance that uses client-driven cognitive strategies. SOT was therapist driven and combined task-specific and component-based training. Goal performance was measured by the therapist-rated Performance Quality Rating Scale (PQRS) and the participant-rated Canadian Occupational Performance Measure (COPM). RESULTS. Using Mann-Whitney U test, we found that CO OP participants showed significantly greater improvement in performance (PQRS, p = .02; COPM Performance, p = .02) compared with SOT but no improvement in satisfaction (COPM Satisfaction, p = .38). CONCLUSION. The CO-OP group demonstrated larger performance improvements than the SOT group. Because of the promising results, an investigation using a larger sample is warranted.
