WHAT IS TRIGGER POINT THERAPY?
Trigger Point – irritated area in muscle fibers that when compressed may elicit pain or a twitching response. This condition occurs mostly in response to muscle tension (overuse) or nervous stress; it is sometimes a result of poor circulation.
When a muscle has tightness or trigger points, the range of motion is also compromised, and the horse will compensate, often leading to further injury.
Trigger Point Therapy (also known as Myotherapy or Neuromuscular Therapy) – a method that applies concentrated finger pressure to trigger points to break cycles of spasm and pain.

Assess the physical condition
It's easy to feel tight muscles on a horse especially when it's unilateral. Subtle changes in texture, temperature and tension can be detected with the hands. The horse's response to touch is another part of the equation. By assessing with touch, you'll also get some ideas as to how the training program is progressing (or not.) Often subclinical issues are hard to recognize, but earlier detection can mean permanent damage is lessened.
