Effect of Specific Postural Corrective Exercises on EMG Activity in Patients With Forward Head Posture

Forward Head Posture Clinical Trial

Official title:
Effect of Specific Postural Corrective Exercises on EMG Activity of Masticatory and Cervical Muscles in Patients With Forward Head Posture

Clinical Trial Summary

This study investigates the effects of specific corrective exercises on EMG of masticatory and cervical muscles in patients with forward head posture. The study's design will be a prospective, double- blinded, randomized controlled trial. The participants will be randomly allocated to one of two groups: the exercise group and the control group. The training groups will perform a program consisting of two strengthening (deep cervical flexors and shoulder retractors) and two stretchings (cervical extensors and pectoral muscles) exercises. This exercise program will be repeated 4 times per week for 10 weeks, and each session lasted 30 minutes. The pre/post assessment of forward head posture will measure by using craniovertebral angle CVA. While the muscle activity EMG of the masseter, temporalis, splenius, upper trapezius, and SCM will measure pre and post-assessment using a biopic data acquisition system. There will be a high significance increase (p-value 0.000) between the pre-and-post CVA between the training groups and the control. And there will be a significant decrease in EMG of the masseter, temporalis, splenius, upper trapezius, and SCM across exercise groups compared to the control. As per the results and analysis, specific postural corrective exercises effectively decrease the EMG of masticatory and cervical muscles in patients with forward head postures.

Clinical Trial Description

Forward head posture (FHD) is a common habitual faulty posture exists in the surrounding that can alter the resting position of the mandible and may affect the masticatory muscle activity. The aim of this study is to investigate the effect of postural correction on masticatory and 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 ARAB UNIVERSITY -Electrodes will be placed on the muscle belly parallel to the direction of muscle fibers. The distance between the two electrodes was 2 cm. The subjects will be instructed to complete maximum voluntary contraction (MVC) of clenching the teeth for 3 s and repeating twice. The average of the two trials of MVC will be used for further analysis. The subjects will be seated comfortably in a chair (---cm height). ;
