Forward Head Posture and Myogenic TMD Association in Smartphone Overuse

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.
