Tip #4 Let's Talk TMJ

GAME CHANGING PERFORMANCE TIP#4

Release TMJ Tension

The temporomandibular joint (TMJ), or jaw joint can be a source of pain for many horses. 

The TMJ has an enormous impact in the correct functioning of the muscular skeletal system. Impairment, loss of functional ability due to wear and tear, trauma or injury,  muscular tension, dental issues or misalignment of this joint can negatively affect balance and movement.

TMJ issues have been recognized as a possible cause of head shaking.   Many nerves run through the TMJ, some of which you will already be familiar with if you read the blog on checking your bridle fit.  There are 12 pairs of cranial nerves  (CN) that stem from the brain rather than the spine that supply the structures of the head.  Any discomfort in these nerves cause considerable facial pain for the horse. 

• The TMJ is the largest joint in the horse’s skull.

• The TMJ allows the mouth to open and close and move in an elliptical fashion.

• The TMJ is closely connected to the hyoid apparatus; EVERY muscle in the horse’s body is in some form connected to the hyoid.

TIP: Release the tension by very, very lightly placing your index finger on the joint. Watch for the horse’s expression, blinking, twitching lips, fidgeting. Stay on the spot and wait for a release. Examples of releases are seen in the video below, however, they may be more subtle, such as a sigh. The method I am demonstrating in the video is the Masterson Method® technique.

The Trigeminal Nerve has three branches that travel outside the head. It is responsible for sensation of the head and face. The Trigeminal Nerve is also the largest cranial nerve.
