Microvascular response in the ECRB muscle of patients with lateral epicondylitis

Oskarsson, Eva,1959-Örebro universitet,Hälsoakademin,Research in musculoskeletal health and disease (författare)

The microvascular response in extensor carpi radialis brevis (ECRB) muscle was studied in thirteen patients with unilateral epicondylitis. At rest the intramuscular blood flow was significantly lower in the affected arm than in the unaffected (P = 0.006). During dorsal extension for 1 min at 40% maximal voluntary contraction (MVC) and 2 min at 20% MVC, blood flow increased significantly in both arms (P = 0.02). Microcirculation remained above resting level both 1 and 2 min after contraction at 40% MVC but was back to the precontraction level 2 min after contraction at 20 % MVC. The reactive hyperaemic response after occlusion of the brachial artery for 5 min, showed no significant difference between the arms. The reason for the hampered microcirculation in ECRB at rest does not seem to be due to a decreased ability of the vessel wall to dilate. Other plausible reasons merits further investigation.
