Clinical Trial Summary

The goal of this observational study is to determine the correlation between forward head posture and myogenic temporomandibular disorder, pain pressure threshold and endurance of masticatory and neck muscles in addicted smart phone users. The main question it aims to answer is: • What is the correlation between forward head posture and myogenic temporomandibular disorder, pain pressure threshold and endurance of masticatory and neck muscles in addicted smart phone users?


Clinical Trial Description

Temporomandibular joint (TMJ) and cervical spine are closely related to each other due to their anatomical, mechanical and neurophysiological relationships. That's why pain and dysfunction in the cervical spine can be observed in patients with temporomandibular disorders (TMD) who may suffer from clinical problems in the masticatory muscles, the temporomandibular joint and other associated structures. Millions of people worldwide use their smartphone devices excessively. Prevalence of smartphone addiction among Egyptian university students was 62.4% revealing that females had a higher addiction than men. This excessive use where subjects downwardly flex their neck to enable them to look at the screen, affects head and neck postures leading to forward head posture (FHP) which consequently alters the position of the mandible along with its functions, resulting in an increase tension in the masticatory muscles causing TMD. Addicted smartphone users contribute to changes in craniocervical region which led to myogenic TMD in young teenagers. Pain, tenderness in masticatory muscles and cervical muscle endurance are common clinical findings in patients with TMD; where muscle tenderness is reduced and cervical muscle endurance was found to have a shorter duration holding time when performing neck extensor endurance test due to higher fatigability of neck extensor muscles. ;
