급성 경항통 환자의 흉쇄유돌근에 대한 근 에너지 기법(MET) 시술 후의 경근전도 변화 연구

ObjectivesTo evaluate the clinical utility of MET performed on sternocleidomastoid mus-cle of acute nuchal pain patients, we measured a change of meridian electromyography.MethodsWe compared electrical activity before and after MET performed on sternoclei-domastoid muscle of acute nuchal pain patients in same group (n=20) in isometric exercise state during five seconds. We analyzed amplitudes and areas of electrical activity and asymmetry index (AI).Results1. After MET performed on sternocleidomastoid muscle of acute nuchal pain pa-tients, maximum voluntary isomeric contraction (MVIC) was significantly increased more than before MET performed (p＜0.005). 2. Comparing with before MET performed on ster-nocleidomastoid muscle of acute nuchal pain patients, muscle fatigue after MET performed on sternocleidomastoid muscle of acute nuchal pain patients decreased but there was no significant difference. 3. Comparing with before MET performed on sternocleidomastoid muscle of acute nuchal pain patients, asymmetry index (AI) after MET performed on sterno-cleidomastoid muscle of acute nuchal pain patients decreased but there was no significant difference.ConclusionsAccording to above results, after performing MET on sternocleidomastoid muscle of acute nuchal pain patients, maximum voluntary isomeric contraction (MVIC) in-creased significantly, so it is certain that performing MET on sternocleidomastoid muscle has a clinical effect.
