Trigger points are formed by localized contractions of a small number of muscles within a larger group. They can be caused by repetitive strain, overuse, and muscle stress. These micro-muscle contractions can cause deep pain, transmitting that pain to nearby joints and muscles.
The term "trigger point" was coined in 1942 by Dr. Janet Travell to describe a clinical finding with the following characteristics:
— Pain related to a discrete, irritable point in skeletal muscle or fascia, not caused by acute local trauma, inflammation, degeneration, neoplasm, or infection.
— The painful point can be felt as a nodule or band in the muscle, and a twitch response can be elicited on stimulation of the trigger point.
— Palpation of the trigger point reproduces the patient's complaint of pain, and the pain radiates in a distribution typical of the specific muscle harboring the trigger point.
— The pain cannot be explained by findings on neurological examination.
Constricted muscles hinder the efficiency of the entire arm and limit your mobility. Daily sessions with The Arm Relief Massager using slow, light, concentrated, pressure on your trigger points, can release tension and pain.
