KNOWLEDGE OF RESULT VERSUS KNOWLEDGE OF PERFORMANCE IN LEARNING MOTOR SKILLED ACTIVITY FOR UPPER LIMB IN RECOVERY STAGE OF STROKE â€“ A RANDOMIZED EXPERIMENTAL STUDY

Dr Dhara Sharma

Abstract :

Purpose of the study: Stroke is a clinical syndrome characterized by the sudden development of a persisting focal neurological deficit. The rehabilitation interventions to treat motor deficits following stroke include, motor learning strategies like strategy development, feedback, practice, etc. knowledge of result and knowledge of performance are two extrinsic feedback. There are scant evidences to conclude which one of them could be more effective for stroke patients. Materials and methods: 30 patients, both males and females were divided into 2 groups by random allocation, group 1 as knowledge of result and group 2 as knowledge of performance. Both the groups were made to practice a task of throwing soft spongy ball, where group 1 got the distance of the throw as feedback and group 2 were showed the video replay of their performance and were given verbal cues. Results: Both the groups showed significant improvement from the pre value to post value of the thrown distance with p value <0.001, but there was no significant difference between the groups shown by p value 0.564. Conclusion: Based on the results, the study concluded that the knowledge of performance proved more effective than knowledge of result for the given task
