This study examined the extent of SMR power in the execution of both in- and anti-phase patterns in bimanual coordination tasks at different speeds. Methods: The present study used a quasi-experimental method. Study participants (n=40, aged: 19-24 years) were selected using convenience sampling method. Study participants were subjected to the 2 bimanual movements with the wrists speed levels ranging from slow to fast; while taking simultaneous records of the EEG. The neurofeedback consisted of SMR frequency of 12-15 Hz at C3 and C4. Data analysis consisted of descriptive statistics and 2-way repeated measures Analysis of Variance (ANOVA) using SPSS. Examination of post-hoc results of importance was conducted using Bonferroni correction paired comparisons. P=0.05 was set as the significance level. Results: The results suggested that SMR power was higher in anti-phase compared to the in-phase model. In addition, the manipulation of bimanual speed affected the SMR power by increasing it in the anti-phase when the speed increased. However, the SMR power did not raise when the in-phase pattern was conducted. Conclusion: Further attention is needed in the anti-phase model as it requires greater SMR power wave. Moreover, with increasing speed, the amount of SMR power can perform a better bimanual linear task. M3 10.32598/ptj.8.1.1 ER -
