Muscle Overload and Trigger Points


It is generally accepted that trigger points occur with muscle overuse and biomechanical stress. 

Muscle overuse and biomechanical stress occur in many forms including maximal concentric (shortening) contractions, overloaded eccentric (lengthening) contractions, sustained low-level contractions, repetitive strain,  maintenance of sustained postures for long periods of time and sustained emotional stress (anxiety, fear, depression).

 We all have the potential to create trigger points on a daily basis.  Often these troubled areas remain latent, below our threshold of awareness.  However, a biomechanically stressful day can turn a latent trigger point into an active one leading to pain, stiffness and suffering.

 Examples of activities that lead to trigger point formation include:


        Working in front of a computer station and using a mouse


        Sporting activities such as running and swimming

        Recreational activities such as gardening and playing a musical instrument

        Sustained loading of muscles from activities such as carrying a baby

        Poor posture

        Muscle tensing due to mental/emotional stress

        Direct injury to the tissue from a fall, strain, break, twist or tear
