Brief 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?

Conditions

Temporomandibular Disorder

Keywords

forward head posture; smartphone

Outcome Measures

Primary Outcomes (1)

• pressure pain threshold

  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.

  5 mintues

Secondary Outcomes (2)

• muscle endurance

  10 minutes

• smartphone addiction scale short version

  2 minutes

Study Arms (2)

subjects with myogenic TMD

Subjects diagnosed as myogenic TMD according to the presence of trigger points in masseter, temporalis, upper trapezius and C5-C6 articular pillars Subjects are heavy smartphones users, using the SAS-SV, the cuffof value for males is 31 and for females is 33. Subjects have forward head posture assessed by CVA \<49.9 degrees

Other: Assessment

subjects without myogenic TMD

Subjects are heavy smartphones users, using the SAS-SV, the cuffof value for males is 31 and for females is 33. Subjects have forward head posture assessed by CVA \<49.9 degrees

Other: Assessment

Interventions

Assessment OTHER

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.
