Objective: This study is to explore effects of the bilateral coordination and activities of daily living on bilateral upper limb movement for hemiplegia patients caused by stroke. Method: This study was a single-subject experimental research with ABA` design. The subjects were two persons who diagnosed as stroke and this design was performed during four weeks for them. Bilateral upper limb movement was done using Janggu(double-headed drum) and drum for 14 days so that both hands can be moved simultaneously. Bimanual coordination function of subjects was measured during baseline phase(5 sessions: A), Intervention(14sessions: B) and baseline return phase`(5 sessions: A`) using Complete Minnetsota Dexterity Test(CMDT) each session. Performance activities of daily living was measured using Assessment of Motor and Process Skills(AMPS) in Pre-Post Bilateral upper limb movement. For analysis of the results, assessment results measured for each subject were suggested through average values and visual graph. Result: Bimanual coordination function of subjects was more improved during Invention period(B)than baseline phase and this improvement was continued during baseline return phase(A`). From the results of comparison between Pre-Post the treatment of Performance activities of daily living difference in Process skill of subject 1 was 0.53, which means statistically significant change. Differences in Movement skill and Process skill of subject 2 were 0.44 and 0.36 respectively, which means clinically meaningful improvement. Conclusion: Bilateral upper limb movement not only improved upper limb function of hemiplegia patients caused by stroke but also was effective in improving Bimanual coordination, which leads to improvement of performance activities of daily living.
