This study aims to investigate whether the differences in mandibular movement between the presence and absence of pain can be noninvasively estimated in patients with temporomandibular disorders and masticatory myofascial pain by measuring jaw motion using commercial smart devices (AirPods Pro and iPhone).
Efficacy
Angular velocity and acceleration of the mandible during jaw movement measured by the IMU sensors of AirPods Pro
*Timepoints:At initial visit and at the time of pain improvement
1. Mandibular motion trajectory captured via facial motion tracking (TrueDepth camera)
2. Pain score using the Numerical Rating Scale (NRS)
3. Maximum mouth opening (mm)
4. Presence of temporomandibular joint sounds (clicking or crepitus)
5. MPIC-J (Multidimensional Pain Inventory for Chronic Pain - Japanese version) scores
6. Clinical findings from muscle palpation of the masticatory muscles
Interventional

Non-randomized

Diagnosis
| Device,equipment |
Participants will wear AirPods Pro (equipped with IMU sensors) and perform 10 repetitions each of mouth opening and protrusive jaw movements while simultaneously being recorded by an iPhone TrueDepth camera. These measurements will be performed at two time points: (1) initial visit (with pain), and (2) after clinical pain improvement. Each session takes approximately 10 minutes. No drugs or invasive procedures are involved.
