- Past history of jaw injury, click, occasional locking
- With or without pain
- Often acute
- Decreased jaw function (i.e. opening and ability to chew)
- Severe limitation of opening (5-30mm)
- Lack of anterior glide of the condyle because disc is blocking movement
- Severe deviation of the jaw on opening towards the affected side
Treatment:
- Muscular Release Techniques – AMRT, massage, contract/relax, IMS, Myofascial release
- Reduce the blockage with mobilization – Distraction and anterior glide
- If disc does not reduce, mobilization to improve opening – Distraction and anterior glide
- Electrotherapy, ultrasound, acupuncture
- Jaw Exercises (often) – Postural correction, self-massage, stretching (opening, contralateral lateral excursion and protrusion), controlled opening
- Splint therapy (anterior positioning splint used temporarily to recapture the disc)
