Electromyographic Effects of Postural Correction Exercises in Individuals With Forward Head Posture

Forward head posture (FHD) is a common habitual faulty posture exists in the surroundingthat can alter the resting position of the mandible and may affect the masticatory muscleactivity.The aim of this study is to investigate the effect of postural correction on masticatoryand cervical muscle activity and mandibular opening in forward‐head posture patients.Materials and Methods:Cranio‐vertebral angle measurement CVA EMG activity of masseter, temporalis, splenius,upper trapezius and SCM BAU ‐ Institutional Review Board (Form H‐II) | BEIRUT ARABUNIVERSITY‐Electrodes will be placed on the muscle belly parallel to the direction of musclefibers. The distance between the two electrodes was 2 cm. The subjects will be instructedto complete maximum voluntary contraction (MVC) of clenching the teeth for 3 s andrepeating twice. The average of the two trials of MVC will be used for further analysis.The subjects will be seated comfortably in a chair.
