TMJ Discomfort
The TMJ is where the temporal bone and mandible come together and form a joint. It has many fascial connections related to far spread areas of the body like the shoulders and hips. The brachiocephalic muscle inserts on the mastoid process of the temporal bone and connects directly onto the shoulder joint. This muscle has the ability to restrict mobility within the TMJ. There are MANY other contributing forces that can impact the TMJ.
The TMJ or Temporomandibular Joint is the most highly innervated joint in the body, meaning that a large number of nerves run by this area on both sides of the head. These nerves service the head, neck and rest of the body.
Problems in this joint can lead to uneven wear on teeth, problems chewing, problems swallowing, a reluctancy to open the mouth, issues with bits, under saddle and more.
Keeping this joint and the surrounding areas happy should be a top priority for your horse! Addressing other issues that may be contributing to dysfunction here is the best way to get a handle on chronic dysfunction.
CranioSacral Therapy and Osteopathy are two fabulous methods for working with the TMJ but most modalities of bodywork have the potential to positively affect the tissues and mobility of the joint.
