安氏Ⅱ类错牙合伴颞下颌关节紊乱病患者经RW-splint治疗前后二腹肌前腹肌电的变化
The change of electromyographic activity of digastrics anterior before and after the RW-splint treatment of Angle classⅡmalocclusion patients with temporomandibular disorders
摘要
Abstract
[Absteract] Objective The investigate the change of the electromyographic activity about digastrics anterior after RW-splint treatment for one week and two monthsin order to offer the theoretic basis for class Ⅱ malocclusion deformity patients with temporomandibular disorders ( temporomandibular, disorders, TMD) . Methods After wearing RW-splint successfully, the electromyographic activities of diagastric anterior before and 1 weeks , 2 months after RW-splint treat-ment were detected by EMG Ⅱ type surface EMG measuring instrument with BioPAK system. Results There was no statistically difference exist ( P>0. 05) in the EMG records of digastric anterior muscle during swallowing position after one week's RW-splint treatment. After 2 months treatment compared with pre-treatment, EMG records of digastric anterior muscle during swallowing position were decreased respectively, which showed remarkable significance ( P<0. 05) . How-ever, after 1 week, 2 months treatment compared with pre-treatment, EMG records of digastric anterior during MMP, which showed no statistically signifcant difference ( P >0. 05) . Conclusion Extension time of RW-splint worn can change the electromyographic activity of digastrics anterior.关键词
