Temporomandibular disorders (TMD) affect the jaw joint and the muscles that move it, causing jaw pain, restricted mouth opening, clicking and often headaches and neck pain. This review set out to measure how well hands-on manual therapy helps, looking at pain, maximum mouth opening and disability.
The authors pooled 20 randomised controlled trials and used the GRADE system to judge the quality of the evidence. Some trials compared manual therapy against sham or a waiting list, while others tested manual therapy added on top of other care.
TMD is common, and jaw, face, head and neck symptoms often overlap with the muscular pain these clinics treat every day. A graded review helps show how effective hands-on care really is.
Hands-on techniques including manual pressure, soft-tissue work, joint mobilisation and stretching applied to the jaw, face and neck muscles and the temporomandibular joint.
Some trials used manual therapy on its own, and others added it to existing care such as exercise, to see what it contributed.
The review found manual therapy helped across the main jaw outcomes.
High and moderate quality evidence supported manual therapy for reducing pain intensity in the short and long term.
Moderate to high quality evidence favoured manual therapy for improving maximum mouth opening, both alone and as an add-on.
Moderate quality evidence showed an additional benefit of manual therapy for jaw-related disability.
The authors note effects, while positive, can be small, so realistic expectations matter.
Across 20 trials, manual therapy was effective for temporomandibular disorders, reducing jaw pain and disability and improving mouth opening in the short and long term, with generally moderate to high quality evidence.
This is solid support for hands-on treatment of the jaw, face and neck in TMD, which sits squarely within myotherapy and physiotherapy scope. It backs combining manual therapy with exercise and self-care for lasting results.
Because TMD symptoms often overlap with neck tension and headache, treating the wider region, not just the jaw, is a sensible, well-rounded approach, coordinated with the person’s dentist or doctor where needed.
Directly supports soft-tissue and trigger point work on the jaw, face and neck muscles as effective treatment for TMD.
Backs manual therapy plus exercise for jaw pain, mouth opening and disability.
Reinforces massage of the masticatory and neck muscles as part of a TMD plan.
Complements needling of jaw trigger points within a broader manual therapy approach.
The included trials varied in technique, dosage and quality, and some effect sizes were small and may not always be clinically meaningful on their own. TMD is multifactorial, involving muscles, joints, stress and sometimes dental factors, so care is best delivered as part of a broader plan.
Manual therapy for the jaw should be coordinated with the person’s dentist or doctor where appropriate. Please confirm the full citation and open-access details against the source before publishing.
Pooling 20 trials, this review found manual therapy effective for TMD, reducing jaw pain and disability and improving mouth opening across the short and long term.
For myotherapists, physiotherapists and dry needling practitioners, it supports hands-on treatment of the jaw, face and neck, combined with exercise and self-care, as a core part of TMD management.
