Temporomandibular Disorders (TMD) is a condition that affects up to 15% of adults and 7% of adolescents, this umbrella term may include jaw pain, movement limitations, and clicking of the jaw (List et al. 2017).
A comprehensive complementary treatment for temporomandibular disorder should incorporate a number of rehabilitation strategies based on patient-specific assessment findings including, but not limited to:
• Manual Therapy (intra-oral and extra-oral massage)
• Acupuncture/electroacupuncture (local, segmental and distal stimulation sites)
• Education on psychosocial factors (eg. BPS framework of pain, fear avoidance)
Why Does Massage Therapy Work For TMD?
Therapeutic effects of intra-oral and extra-oral massage, and self-care management of temporomandibular dysfunction has been demonstrated in a number of randomized control trials and systematic reviews (Martins et al. 2016, von Piekartz & Hall 2013, Randhawa et al. 2015).
Evidence also suggests that temporomandibular disorder may be a contributing factor to cervicogenic headache (von Piekartz & Hall 2013).
A biopsychosocial framework helps put into context the interconnected and multidirectional interaction between: physiology, thoughts, emotions, behaviors, culture, and beliefs. In terms of clinical responses to massage therapy there are a couple of proposed mechanisms of action, including but not limited to: Affective Touch, Contextual Factors, Endogenous Pain Modulation, Mechanical Factors, and Neuroplasticity.
Acupuncture for TMD?
Medical acupuncture is an approach that is based upon a theory that is inline current scientific understanding of how the body works. Using occam's razor the insertion of an acupuncture needle is a form of novel stimuli, that functions by sending anti-nociceptive input to the neuroimmune system (Chen et al. 2017).
Preferential sites for acupuncture stimulation are associated with areas rich in specialized sensory receptors such as muscle spindles, Golgi tendon organs, ligament receptors, Paciniform and Ruffini’s receptors (joint capsules), deep pressure endings (within muscle belly), and free nerve endings (muscle and fascia). All of these areas are highly innervated and as a result there are a number of physiological responses that help modulate the experience of pain.
Structures to be aware of when treating TMD
Intra-oral and extra-oral massage is not complicated, it can be preformed in the clinic or as self care. In its simplest form it could include working on:
• Medial pterygoid
• Scalene Muscle Group
• Upper Cervical Spine (Suboccipitals, Upper trapezius, Splenius Cervicis, Splenius Capitis)
