The Effects of Transcranial Direct Current Stimulation Combined Neuromuscular Training on the Lower Extremity Muscle of the Soccer Player with Ankle Instability
Uhm Yo-Han

Abstract
Purpose: This study aims to examine the effect on the lower extremity muscle activity of soccer player havingchronic ankle instability by mediating neuromuscular training combining transcranial direct current stimulation.

Method: Thirty college soccer players were selected as the participants of study, and divided into aneuromuscular training group combining transcranial direct current stimulation (Experimental group) and ageneral neuromuscular training group (Control group), and 15 participants randomly assigned. The participantsof this study additionally intervented neuromuscular training combining transcranial direct current stimulationand general neuromuscular training to each group for 30 minutes five times a week for eight weeks afterreceiving general soccer training. The attached to active C3, C4, CZ. Lower extremity muscle activity wasanalyzed before the intervention. Tibialis anterior, gastrocnemius and soleus were measured by maximumvoluntary isometric contraction in the in the bare-handed muscle strength test posture in order to analyzethe lower extremity muscle activity. Above outcomes were equally remeasured and in intergroup analysis wasconducted after eight weeks of intervention.

Result: The neuromuscular training group combining transcranial direct current stimulation (Experimentalgroup) showed a statistically significant difference in lower extremity muscle activity compared to the generalneuromuscular training group (Control group) as a result of comparing and analyzing the lower extremitymuscle activity between two groups(p<.05).

Conclusion: It was found that the neuromuscular training combining transcranial direct current stimulation ismore effective in improving lower extremity muscle activity as a result of above. The basic data on the possibilityof using tDCS in the filed of soccer player sports rehabilitation could be provided based on this study.
