Masticatory Muscles Electromyography in Post-pubertal Females With Forward Head Posture and Temporomandibular Disorders

The aim of this study was to evaluate masticatory muscle electrical activity in post-pubertal females with forward head posture (FHP) and temporomandibular disorders (TMD) as well as in post-pubertal females with neutral head posture and with no temporomandibular disorders.

About this study

It has been demonstrated by a previous study that a strong relationship exists between forward head posture and temporomandibular disorders and that individuals with forward head posture and temporomandibular disorders exhibit alterations in masticatory muscle electromyographic activity either as a result of the disorder itself or due to a compensatory mechanism associated with the symptoms of temporomandibular disorders . As a consequence, the aim of the study was to evaluate the electromyographic activity of the masticatory muscles in post-pubertal females with forward head posture and temporomandibular disorders as well as in post-pubertal females with neutral head posture and with no temporomandibular disorders.
