Notes

An increased tension and a low intramuscular blood flow in the extensor carpi radialis (ECRB) muscle in patient with lateral epichondylitis has been suggested to contribute to the symptoms. The reason for the lower blood flow may be increased intramuscular pressure. The purpose of this pilot study was to determine intramuscular pressure and blood flow in affected and unaffected ECRB in ten patients with unilateral epicondylitis, with a mean duration of symptoms of 24 (13-48) months. Intramuscular pressure (IMP) was measured using the microcapillary infusion technique and intramuscular blood flow using the laser Doppler flowmetry technique, bilaterally with the non-affected arm serving as a control. The recordings were performed at rest, during isometric dorsal extension of the wrist for 1 min at 40 % and 2 min at 20 % of maximal voluntary contraction (MVC) and during recovery after contractions. At rest the median IMP was 7-8 mm Hg regardless of arm while the median intramuscular blood flow was lower on the affected side compared with the unaffected side (P=0.03). During contraction the IMP and blood flow increased regardless of arm. The IMP fell to pre-contraction level within 2 s after contraction, independent of arm and contraction force. Recovery, regarding the intramuscular blood flow, tended to be faster on the unaffected side than on the affected after contraction at 20 % MVC. After contraction at 40 % MVC the blood flow was equal on both sides. When the IMP value in the unaffected muscle was corrected for the higher force elicited compared to affected muscle the adjusted IMP was significantly lower (P=0.006) at 20 % MVC. In summary, affected ECRB has a lower intramuscular blood flow during rest and a higher intramuscular pressure in relation to the unaffected muscle at contraction for 2 min at 20 % MVC.
