Abstract:
Objective:To investigate the electromyography activities of the facial and neck muscles during mandibular movement in children with high-angle.Methods:A computer-integrated BioEMG Ⅱ diagnostic system was used to synchronously record the electromyography activities of temporal anterior(TA), masseter muscle(MM), sternocleidomastoid(SCM) and digastric anterior(DA) muscles during mandibular movement in 14 children with high-angle and 16 children with normal-angle.Results:Muscular activity of TA, DA and SCM in children with high-angle was significantly weaker than that in those with normal-angle in the rest position(P
