Inter-task transfer of meaningful, functional skills following a cognitive-based treatment: Results of three multiple baseline design experiments in adults with chronic stroke

The transfer of skills learned in rehabilitation to new skills in the home has hitherto been notoriously difficult to achieve. The Cognitive Orientation to daily Occupational Performance (CO-OP) treatment approach has been associated with improved performance in people living with stroke, but the specific impact on transfer to untrained skills has not been investigated. The objective of the study was to investigate the capacity of CO-OP treatment to improve performance in both trained and untrained self-selected skills in adults living with stroke. A single case experiment with multiple baselines across skills was conducted, with two replications. The participants self-selected four skills; three were trained using CO-OP; the fourth was not. Using video recording, data points were collected at multiple baselines, during intervention, post-intervention, and at follow-up. The Performance Quality Rating Scale (PQRS) was used by an independent rater to score performances. The two-standard deviation band method was used to determine the significance of improvements. At follow-up, significant performance improvements were seen in all three single case experiments in all trained and untrained skills. A cognitive-based approach was associated with improved performance in trained and untrained skills in three adults with chronic stroke; further controlled research is warranted.
