Trial and error versus errorless learning of functional skills in patients with acute stroke.

OBJECTIVE

To compare the effectiveness of errorless learning versus trial and error learning for teaching activities of daily living to patients with acute stroke with or without explicit memory impairments.

DESIGN

Randomized crossover.

SETTING

Rehabilitation hospital.

PARTICIPANTS

Thirty-three adult subjects following an acute stroke.

INTERVENTION

Subjects were taught to prepare a wheelchair for a transfer and to put on a sock with a sock-donner. Tasks were taught using errorless learning or trial and error learning. Explicit memory was assessed using the Neurobehavioral Cognitive Status Exam.

MAIN OUTCOME MEASURES

Days until subject was able to demonstrate retention of the task, and success or failure at carry-over to a similar task.

RESULTS

No significant differences were found in days to retention for either functional task when taught using errorless learning or trial and error learning in subjects with or without explicit memory impairments. Carry-over was significantly better when trial and error learning was used for learning sock donning.

CONCLUSIONS

When choosing the best learning method for patients undergoing rehabilitation for stroke, the nature of the task should be considered. Additional research is needed to identify the best approach for teaching activities of daily living and facilitating carry-over of learning in individuals with acute stroke.
