Here is 29 year old Red showing some processing and releases during treatment to his jaw (temperomandibular joint) and his hyoid apparatus π¦΄
The TMJ is a complex joint where the mandible (the jaw bone) meets and articulates with the temporal bone which enables the opening/closing of the mouth as well as the lateral gliding required for mastication (chewing)! π
Did you know it is the most proprioceptive joint in the whole body!!
There are 4 main muscles associated with mastication,
so all play a huge role in the function of the TMJ! These muscles include:
πͺπΌ Masseter
πͺπΌ Temporalis
πͺπΌ Petrygoid group
πͺπΌ Digastric
Problems related to the TMJ are often not well understood and therefore may not alway be diagnosed. Due to its complexity it isnβt a straightforward presentation of an issue and can be portrayed in multiple ways. Signs of dysfunction in the TMJ can include:
π¦· Change in head carriage
π¦· Quidding (dropping food)
π¦· Uneven wear on teeth
π¦· Head shaking
π¦· Bitting issues
π¦· Pain/reactivity on palpation
π¦· Reduced jaw range of motion
π¦· Muscle asymmetry
π¦· Joint thickening
π¦· Head tilt
π¦· Reduced lateral flexion in the neck
π¦· Poll tension
π¦· Asymmetric forelimb protraction
π¦· Difficulty picking up correct canter lead
π¦· General performance issues
Did you know the TMJ has been directly linked to reduced hindlimb range of motion and reduced performance due to itβs association with the vestibular system which plays a huge role in balance and is also linked with many myofascial lines.
Massage and positional releases are a great way to help in restoring function to the TMJ which is usually accompanied with signs of release alike lowering the head, slow blinking, licking & chewing, or yawning π₯± see how in this video the horses face has softened with twitching of the muzzle and the slow blinking which are both signs of release!
