Jaw Pain and Physical Therapy Treatments

Temporomandibular Disorders (TMJ/TMD)

Problem

TMJ/TMD are a major cause of non dental jaw and facial pain.  Approximately 18 million word days are lost annually per 100 million full time working adults due to symptoms of TMD (2).  

Women have a 3:1 greater ratio of incidence compared to men between age 30 and 50 (1).

Disk Displacement and Arthritic symptoms peak at age 30 and 50, respectively (1).

Symptoms can be broken down into 3 areas:

Muscle or myofascial pain (45%), Osteoarthritis (41%), and Osteoarthrosis

Physical Therapy Treatments

Review articles support a mulimodal approach for the management of TMD including: joint mobilization/manipulation, soft tissue mobilization, active exercise, proprioception training, and relaxation training (6,7,11).

Evidence for Physical Therapy Interventions 

Shiffman et al. found rehabilitation was as effective as arthroscopic surgery or arthroplasty (4).

Manual therapy has been shown to be more cost effective and less prone to side effects than dental treatments (5).

Dry needling of the facial muscles has shown positive results in recent trials (12).

Neuromuscular re education and behavioral changes are more effective than splinting (6).

Nicolakis et al. demonstrated >85% of patients with TMD treated with PT report excellent functional improvement, reduce pain, and improved ROM.  76% of patients required no further care up to 3 years after treatment (8,9).

Furto et al. demonstrated improved short term outcomes following Physical Therapy treatments involving manual therapy and exercise (10).

Manual therapy interventions to the cervical and thoracic spines, as well as, dry needling has demonstrated further improvements in pain and disability (12). 

When to Refer to Physical Therapy

Patients with TMD often display signs and symptoms including: TMJ pain and myofascial pain in the face, jaw or neck, TMJ sounds, restrictions, deviations, or deflections of the jaw during jaw opening and closing.

The American Association for Dental Research reports

"Unless there are specific and justifiable indications to the contrary, treatment of patients with TMD initially should be based on the use of conservative, reversible, and evidence based therapeutic modalities."
