Electromyography in Myofascial Syndrome
نویسنده
چکیده
Myofascial syndrome is a muscular pain syndrome with regional symptoms, often in limb girdle or neck and back area. It is common and causes much disability and inability to work. Myofascial pain may be activated by precision work, repetitive strain or recent injury. Typical findings in symptomatic muscles are taut bands and painful trigger points (TrPs), where pressure elicites a typical spreading of pain (Cummings & Baldry, 2007). Microdialysis of TrPs has detected local elevation of contraction, and inflammatory and pain metabolites (Shah et al., 2008). Reduced high-energy phosphate levels but no signs of myositis have observed in painful muscles in histological studies (Bengtsson et al., 1986).
