Interrelationship Between Asymmetric Body Posture and Resting Electromyographic Activity of the Masseter Muscle The aim of this study was to determine whether an interrelationship exists between asymmetric body posture and the resting electromyographic activity of the masseter muscle.Eight postural parameter (rotation of the cervical spine, shoulder height, scapular abduction, iliac crest height, shortening of trapezius, quadratus lumbarum, iliopsoas and hip adductor muscles) were evaluated for asymmetry in 30 patients and were combined in a score. These parameters were compared with asymmetry of the resting electromyographic activity of the masseter muscle.Pelvic obliquity correlated with a contralateral electromyographic activity of the masseter muscle, scapular abduction with an ipsilateral increased electromyographic activity of the masseter.The whole score corralated with the asymmetry of the surface electromyography of the masseter.We conclude that an interrelationship exists between body posture and the craniomandibular system.
