Activity Description

Myofascial trigger points are focal "knots" located in a taut band of skeletal muscle first described by Dr. Janet Travell in 1942. Trigger points may be formed after acute trauma or by repeated micro-trauma, leading to stress on muscle fibers. Trigger point injections are a therapeutic modality to treat myofascial trigger points, especially in symptomatic patients, and have been demonstrated effectiveness to inactivate trigger points.

Trigger point injections can be wonderful adjunctive or primary therapy, alongside muscle relaxants, and other medications aimed at decreasing pain in the musculoskeletal system.
