PURPOSE: The objective of this research is to investigate the effectiveness of mental practice on function and muscle activation of upper extremity (UE) in stroke patients.
METHODS: The mental practice was conducted on 12 subjects for 10 minutes and the related existing work treatment for 20 minutes. The evaluation for the function of UE proceeded with Fugl-Meyer assessment of motor function (FMA) and muscle activity analysis instrument. Furthermore we analyzed patients’ reaching activity by two stages, reaching phase and returning to original position phase.
RESULTS: According to the research results, the subjects’ upper limb function improved in all of the measured items and the total scores after the mental practice (p<.05). In muscle activity, CCR value was used to efficiently analyze the patients’ reaching activity in the two stages of reaching stage and returning to the original position phase. While the elbow movement only had a bit of positive change (1.1%) in the reaching stage, both the shoulder (-12.3%) and elbow (-18.2%) movements had a positive change in the returning to original position phase.
CONCLUSION: This research confirmed that the mental practice is effective for the enhancement of UE function for stroke patients. The result of this research can contribute to the progress of mental practice in clinical environment.
