简要总结
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?
详细描述
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.

结局指标
主要结局
pressure pain threshold
时间窗: 5 mintues
For the masticatory muscles, the subject will be sitting and the therapist will place the pressure algometer on the belly of the masseter and temporalis muscles. A gradual pressure will be applied until the subject experiences pain. The value displayed on the device will be recorded. This will be repeated 3 times on each side. For the upper trapezius muscles, subject will be seated. Using the algometer, a pressure will be applied on midpoint of the trapezius. Then subject will lie prone, to apply pressure by the algometer on a point 1 cm laterally to the midpoint between C6 and C5 spinous processes. A value will be recorded when subject feels pain. This will be repeated 3 times on each side.
次要结局
- muscle endurance(10 minutes)
- smartphone addiction scale short version(2 minutes)
