Abstract

Objective:Transcranial direct current stimulation (tDCS) is one of the newest methods of influencing the nervous system to improve motor performance, including coordination. The aim of the present study is to investigate the effect of tDCS and music combined with practice on learning bimanual coordination movement.

Methods:The present study was based on a pretest, post-test, and retention design. 48students (mean age 22.32) were randomly divided into four experimental groups (sham tDCS with practice, practice with music, real tDCS with practice, and real tDCS with music and practice). Participants performed the bimanual circle drawing task during four stages: pre-test, intervention (4 sessions, each session consisting of 4blocks of 10trials), post-test, and retention after 48 hours. Radial drawing error and hand movement speed were measured. The statistical method of combined analysis of variance was used using SPSS at a significance level of 0.05.

Findings: The results showed that training significantly affected learning of the bimanual task in all four groups. Also, the training with real tDCS, training with music, and training with real tDCS, training with music groups had greater progress in reducing radial error than the training group without music and stimulation; but there was no difference between the groups in the speed component.

Conclusion:Considering the effect of music and real stimulation, it is suggested to use these two methods in learning these tasks.Also, considering the greater learning of musical groups, it seems that music has a greater effect than stimulation. However, using these two methods simultaneously does not have much effect.
