It can appear in any body part. Characteristic features of a myofascial trigger points 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.[1] SymptomsMyofascial pain is pain in muscles or fascia (a type of connective tissue that surrounds muscles). It can occur in distinct, isolated areas of the body. Because any muscle or fascia in the body may be affected, this may cause a variety of localized symptoms. Generally speaking, the muscular pain is steady, aching, and deep. Depending on the case and location the intensity can range from mild discomfort to excruciating and "lightning-like". Knots may be visible or felt beneath the skin. The pain does not resolve on its own, even after typical first-aid self-care such as ice, heat, and rest.[2] Myofascial pain syndromes are characterized by localized pain in an area of repetitive use or trauma with resultant trigger points that cause non-dermatomal pain radiation upon palpation. Autonomic dysfunction and spontaneous EMG activity can be seen in the affected region. CausesThe causes of MPS are not fully documented or understood. At least one study rules out trigger points: "The theory of myofascial pain syndrome (MPS) caused by trigger points (TrPs) ... has been refuted. This is not to deny the existence of the clinical phenomena themselves, for which scientifically sound and logically plausible explanations based on known neurophysiological phenomena can be advanced."[3] Some systemic diseases, such as connective tissue disease, can cause MPS.[4] Poor posture and emotional disturbance might also instigate or contribute to MPS.[5] Diagnosis{{Empty section|date=November 2017}}TreatmentMassage therapy using trigger-point release techniques may be effective in short-term pain relief.[6] Physical therapy involving gentle stretching and exercise is useful for recovering full range of motion and motor coordination. Once the trigger points are gone, muscle strengthening exercise can begin, supporting long-term health of the local muscle system.{{sfn|Starlanyl|Copeland|2001|page=221}} Myofascial release, which involves gentle fascia manipulation and massage, may improve or remediate the condition.[7]A systematic review concluded that dry needling for the treatment of myofascial pain syndrome in the lower back appeared to be a useful adjunct to standard therapies, but that clear recommendations could not be made because the published studies were small and of low quality.[8] (See also: Fu's subcutaneous needle) Posture evaluation and ergonomics may provide significant relief in the early stages of treatment.{{sfn|Starlanyl|Copeland|2001|page=230}} Movement therapies such as Alexander Technique and Feldenkrais Method may also be helpful.{{sfn|Starlanyl|Copeland|2001|page=232}} Gentle, sustained stretching exercises within a comfortable range of motion have been shown to lessen symptoms. Regular, non-intense activity is also encouraged.[9] References1. ^{{cite journal |doi=10.1016/j.berh.2007.02.014 |title=Myofascial pain syndromes and their evaluation |year=2007 |last1=Bennett |first1=Robert |journal=Best Practice & Research Clinical Rheumatology |volume=21 |issue=3 |pages=427–45 |pmid=17602992}} 2. ^{{cite web|url=http://www.mayoclinic.com/health/myofascial-pain-syndrome/DS01042/DSECTION=symptoms|title= Myofascial pain syndrome: Symptoms|author= Mayo Clinic Staff|date= 3 Dec 2009|accessdate=8 May 2011}} 3. ^{{cite journal |pmid=25477053 |title=A critical evaluation of the trigger point phenomenon |publisher=Rheumatology (Oxford). 2015 Mar;54(3):392-9. doi: 10.1093/rheumatology/keu471.
