Objective: The aim of this study was to investigate effects of the two-hand coordination training tool on visual perception and hand dexterity in chronic stroke patients and to propose the role of the tool as a training method. Methods: Forty one participants were recruited based on the inclusion and exclusion criteria of the study and they were randomly divided into two groups. The combination of the two-hand coordination training tool(15 minutes) and traditional occupational therapy(15 minutes) were provided for the experimental group. On the other hand, only the traditional therapy given to the control group. The experiment lasted for six weeks and participants were required to attend the session for five days a week. Motor-free Visual Perception Test-3(MVPT-3) and Complete Minnesota Dexterity Test(CMDT) were used as outcome measures for both groups. Outcomes were measured every third weeks including intial measurement. Results: In the control group, completion time of CMDT was not significantly different between time periods (p>.05) while the time decreased over the period of experiment and the number of errors were significantly different between time periods (p<.05). There was increase in the scores of MVPT in the experimental group over time and the difference was statistically significant(p<.05) in the experimental group. Furthermore, group differences were shown at third and sixth week. There was no significant difference in the scores of CMDT between groups and between time periods. Conclusion: Findings of the results suggest that the training tool for two-hand coordination is effective and applicable for rehabilitation for visual perception and functional ability of upper extremity. Therefore, we hope this tool could be utilized both at home and hospital.
