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?

Detailed 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.

Conditions

• Temporomandibular Disorder

Interventions

Type	Name	Description
OTHER	Assessment	All subjects will be assessed for FHP by taking a lateral view picture to calculate the CVA using the Kinovea software. Each subject with FHP will be examined for myofascial trigger points done by the therapist finger to palpate bilaterally on tender nodules in masticatory and neck muscles. Then using a pressure algometer, the PPT value will be scored for each trigger in each muscle bilaterally. Masticatory muscle endurance will be measured by asking the subject to bite on load sensor for as long as the subject can until exhaustion. Using a stopwatch, the time will be recorded in seconds. Using the craniocervical extension endurance test, the subject will lie prone with their head unsupported and with a bubble inclinometer attached to their head. Using a stopwatch, time in seconds will be recorded to test how long the subject can sustain the neck in neutral position. Finally, a smartphone addiction scale will be answered by the subject to identify how much they are addicted to its use.
