Ten patients with unilateral epicondylitis, mean duration of symptoms of 39 (12\u201396) months participated. The diagnosis was based on clinical examination and none was under treatment for the last 6 months. Isometric handgrip strength, 2\u2010pinch grip strength and muscle strength during radial deviation and dorsal extension were determined. Functional perceived pain was evaluated by a modified behaviour rating scale and perceived pain during contraction by visual analogue scale. Intramuscular and skin blood flow was recorded by a laser\u2010Doppler flowmetry system technique (LDF) during stable temperature condition. Intramuscular blood flow was significantly lower in the affected side, 22.7\u00b19.8\u2003perfusion units (PU), as compared with 35.2\u00b111.9\u2003PU in the control side (<jats:italic>P<\/jats:italic>=0.01). There was no difference in skin blood flow or temperature between the affected and the control side. A positive correlation was found between the duration of symptoms and the difference in intramuscular blood flow between the affected and the control arm (<jats:italic>r<\/jats:italic>=0.65, <jats:italic>P<\/jats:italic>=0.06). The present data indicate that decreased microcirculation and anaerobic metabolism in ECRB may contribute to the lateral epicondylitis symptoms.<\/jats:p>","DOI":"10.1111\/j.1600-0838.2006.00567.x","type":"journal-article","created":{"date-parts":[[2006,6,28]],"date-time":"2006-06-28T12:08:48Z","timestamp":1151496528000},"page":"211-215","source":"Crossref","is-referenced-by-count":26,"title":["Decreased intramuscular blood flow in patients with lateral epicondylitis"],"prefix":"10.1111","volume":"17","author":[{"given":"E.","family":"Oskarsson","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.\u2010E.","family":"Gustafsson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.","family":"Pettersson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"K.Piehl","family":"Aulin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,6,28]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/000164700317381162"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0838.2000.010006365.x"},{"key":"e_1_2_6_4_1","first-page":"41","volume-title":"Clinical assessment recommendations","author":"Fess EE.","year":"1992"},{"key":"e_1_2_6_5_1","first-page":"47","article-title":"Temporomandibular joint and myofascial pain dysfunction\u2010some current concepts.
