N2 - The present study aimed to evaluate the surface electromyography (sEMG) activity of the masseter muscles in patients with a history of temporomandibular joint disorder (TMJD) who receivedorthodontic treatment. In total, 22 participants aged 18–35 years old were included in this study.They were divided into the control group (patients without a history of TMJD [n = 11]) and the testgroup (those with a history of TMJD [n = 11]). Each participant underwent sEMG of the right andleft masseter muscles at 5-s maximum voluntary contraction (MVC). Results showed that the TMJDgroup had a lower sEMG activity of masseter muscles at MVC than the non-TMJD group. However, thedifferences were not statistically significant (p > 0.05, t-test). The Spearman’s correlation coefficient testrevealed a weak negative correlation between muscle activity on sEMG and history of TMJD (p > 0.05).In conclusion, orthodontically treated patients in TMJD group have reduced masseter muscle activityduring MVC, compare to the non-TMJD group
