Trigger Points


Trigger points, otherwise known as ‘knots’ can cause loss of oxygen and nutrient depletion to the affected muscle.  This presents itself as loss of motor function and chronic pain. 


Trigger points can appear anywhere in the body and are usually found in the belly of the muscle.  They develop when the actin and myosin filaments do not relax after contraction and form a taught band of fibres within the muscle, usually in response to muscle tension due to overuse or nervous stress.  Occasionally sluggish circulation from lack of activity can also produce trigger points. 


A build up of lactic acid can also result in the formation of a trigger point.  The local motor nerve endings develop an irritation.  Pressure applied to these trigger points will send a pain referral to other parts of the body.
