Abstract
|
|
|
Trigger points are discrete, focal, hyperirritable spots located in a taut band of skeletal muscle. They produce pain locally and in a referred pattern. Patients may have regional, persistent pain resulting in a decreased range of motion in the affected muscles. Acute trauma or repetitive microtrauma may lead to the development of stress on muscle fibers and the formation of trigger points. Diagnosis of trigger point is made by clinical examination. Palpation if a hypersensitive bundle or nodule of muscle fiber is harder than normal consistency. Palpation of the trigger point will elicit pain directly over the affected area and/or cause radiation of pain toward a zone of reference and a local twitch response. Trigger points may also manifest as tension headache, tinnitus, temporomandibular joint pain, decreased range of motion in the legs, and low back pain. Various therapeutics, such as the spray and stretch technique, ultrasonography, manipulative therapy and injection, are used to inactivate trigger points. Among them, trigger-point injection has been shown to be one of the most
effective therapeutic modalities to inactivate trigger points and provide prompt relief of symptoms.
