چکیده

مقدمه: تحریک الکتریکی فراجمجمه‌ای ‌با جریان مستقیم (tDCS) یکی از جدیدترین روش‌های اثرگذاری بر سیستم عصبی برای بهبود عملکرد حرکتی از جمله هماهنگی است. هدف پژوهش حاضر بررسی تاثیر tDCS و موسیقی همراه با تمرین بر یادگیری حرکت هماهنگی دودستی است.
روش‌شناسی: پژوهش حاضر بر طرح پیش‌آزمون، پس‌آزمون و یادداری مبتنی بود. 48 دانشجو (میانگین سنی 32/22) که به‌صورت تصادفی در چهار گروه (tDCS ساختگی همراه با تمرین، تمرین همراه با موسیقی، tDCSواقعی همراه با تمرین و tDCS واقعی همراه با موسیقی و تمرین) تقسیم شدند. شرکت‌کنندگان تکلیف دودستی ترسیم دوایر را در طی چهار مرحلة پیش‌آزمون، مداخله (4 جلسه، هر جلسه 4بلوک 10 کوششی)، پس‌آزمون و یادداری پس از 48 ساعت انجام داده‌اند. خطای شعاعی ترسیم و سرعت حرکت دست اندازه‌گیری شد. روش آماری تحلیل واریانس مرکب با استفاده از SPSS در سطح معناداری 05/0 استفاده شد.
یافته‌ها: نتایج نشان داد تمرین بر یادگیری تکیف دودستی در هر چهار گروه معنادار تأثیرگذار است. همچنین گروه‌های تمرین همراه با tDCS واقعی، تمرین همراه با موسیقی و تمرین همراه با tDCS واقعی، تمرین همراه با موسیقی نسبت به گروه تمرین بدون موسیقی و تحریک پیشرفت بیشتری در کاهش خطای شعاعی داشتند؛ اما در مؤلفة سرعت تفاوتی بین گروه‌ها نبود.
نتیجه‌گیری: با توجه تاثیر موسیقی و تحریک واقعی، پیشنهاد می‌شود در یادگیری تکالیف هماهنگی از این دو روش استفاده شود. همچنین با توجه به پیشرفتِ بیشترِ گروه‌های موسیقی، به‌نظر می‌رسد موسیقی تأثیر بیشتری نسبت به تحریک دارد. با این وجود، استفادة همزمان از این دو روش تأثیر زیادی ندارد.

چکیده [English]

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.
