Activation of trigger points may be caused by a number of factors, including acute or chronic muscle overload, activation by other trigger points (key/satellite, primary/secondary), disease, psychological distress (via systemic inflammation), homeostatic imbalances, direct trauma to the region, collision trauma (such as a car crash which stresses many muscles and causes instant trigger points ...
Symptoms of a myofascial trigger point include: focal point tenderness, reproduction of pain upon trigger point palpation, hardening of the muscle upon trigger point palpation, pseudo-weakness of the involved muscle, referred pain, and limited range of motion following approximately 5 seconds of sustained trigger point pressure. [2] The cause ...
A compartment space is anatomically determined by an unyielding fascial (and osseous) enclosure of the muscles.The anterior compartment syndrome of the lower leg (often referred to simply as anterior compartment syndrome), can affect any and all four muscles of that compartment: tibialis anterior, extensor hallucis longus, extensor digitorum longus, and peroneus tertius.
In the treatment of trigger points for persons with myofascial pain syndrome, dry needling is an invasive procedure in which a filiform needle is inserted into the skin and muscle directly at a myofascial trigger point. A myofascial trigger point consists of multiple, hyperirritable contraction knots related to the production and maintenance of ...
Some early research points to genetic butylcholinesterase deficiency as a possible candidate component in sudden infant death syndrome. [13] The enzyme Acetylcholin esterase, and its inhibition, plays a role in the development of myofascial trigger points and the associated myofascial pain syndrome.
In neuroscience and neurology, a trigger zone is an area in the body, or of a cell, in which a specific type of stimulation triggers a specific type of response. The term was first used in this context around 1914 by Hugh T. Patrick, who was writing about trigeminal neuralgia , a condition in which pain fibers in the trigeminal nerve become ...

Ischemic compression is commonly applied to trigger points, in what is known as trigger point therapy, where enough sustained pressure is applied to a trigger point with a tolerable amount of pain, and as discomfort is reduced, additional pressure is gradually given.
