A PRIMARY DIAGNOSTIC FINDING IN TMJ, TMD, TMJ DISORDERS IS MYOFASCIAL TRIGGER POINTS. THEY ARE FREQUENTLY ASSOCIATED WITH FORWARD HEAD POSTURE A COmMON FINDING IN TMJ PATIENTS.

NEUROMUSCULAR DENTISTRY UTILIZES A DIAGNOSTIC NEUROMUSCULAR ORTHOTIC AND TENS TO ELIMINATE THE FACTORS THAT CAUSE TRIGGER POINTS TO FORM AND PROPAGATE. ELIMINATION OF THESE TRIGGER POINTS CAN PREVENT TMJ DISORDERS, TREAT TMD AND CHRONIC TENSION TYPE HEADACHES. PATIENTS WITH INCREASED MYOFASCIAL TRIGGERS ALSO HAVE INCREASED INTENSITY AND DURATION OF HEADACHE ATTACKS.
A DIAGNOSTIC NEUROMUSCULAR ORTHOTIC IS A SAFE AND EFFECTIVE FIRST STEP IN THE DIAGNOSIS, TREATMENT AND ELIMINATION OF MYOFASCIAL TRIGGERS AND RELATED TMJ AND HEADACHE DISORDERS.

Abstract
OBJECTIVE: To assess the presence of trigger points (TrPs) in several head and neck muscles in subjects with chronic tension-type headache (CTTH) and in healthy subjects; and to evaluate the relationship of these TrPs with forward head posture (FHP), headache intensity, duration, and frequency.
BACKGROUND: Tension-type headache (TTH) is a headache in which myofascial TrPs in head and neck muscles might play an important etiologic role.
DESIGN: A blinded, controlled, pilot study.
METHODS: Twenty-five CTTH subjects and 25 matched controls without headache were studied. TrPs in bilateral upper trapezius, sternocleidomastoids, and temporalis muscles were identified according to Simons et al's diagnostic criteria: tenderness in a hyperirritable spot within a palpable taut band, local twitch response elicited by snapping palpation, and elicited referred pain with palpation. A TrP was considered active if the subject recognized the evoked referred pain as familiar headache. If the evoked referred pain was not recognized as familiar headache, the TrP was considered as latent. Side-view pictures of each subject were taken in both sitting and standing positions in order to assess FHP by measuring the cranio-vertebral angle. Both measurements were made by a blinded assessor. A headache diary was kept for 4 weeks in order to assess headache intensity, frequency, and duration.
RESULTS: The mean number of TrPs on each CTTH subject was 3.9 (SD: 1.2), of which 1.9 (SD: 1.2) were active TrPs and 1.9 (SD: 0.8) were latent TrPs. Control subjects only exhibited latent TrPs (mean: 1.4; SD: 0.8). There was a significant difference between the CTTH group and the controls for active TrPs (P < .001), but not for latent TrPs (P > .05). Differences in the distribution of active and latent TrPs within each muscle were also significant for all the analyzed muscles (P < .01). CTTH subjects with active TrPs in the right upper trapezius muscle or left sternocleidomastoid muscle showed a greater headache intensity and duration, but not headache frequency, compared to those with latent TrPs (P < .05). Active TrPs in the right temporalis muscle were associated with longer headache duration (P < .01), whereas active TrPs in the left temporalis muscle were associated with greater headache intensity (P < .05). CTTH subjects with active TrPs in the analyzed muscles had a greater FHP than those with latent TrPs in both sitting and standing positions. Differences were only significant for TrPs in the left sternocleidomastoid and FHP in the sitting position (P < .01).
CONCLUSIONS: Active TrPs in upper trapezius, sternocleidomastoid, and temporalis muscles were associated with CTTH. CTTH subjects with active TrPs usually reported a greater headache intensity and longer headache duration than those with latent TrPs. CTTH subjects with active TrPs tended to have a greater FHP than CTTH subjects with latent TrPs.
