Abstract: Objective To explore the effect of wrist extensor energy on humeral epicondylitis. Methods 48 humeral epicondylitis patients were divided into muscular energy group and block therapy group with 24 cases in each group. The muscular energy group was treated with muscle energy technique, and the other group received block therapy. They were assessed with Visual Analogue Scale (VAS) and muscle strength. They were followed up 3 months, 6 months and 1 year after discharge. Results The score of VAS was lower in the block therapy group than in the muscular energy group (P<0.01), and the muscle strength was weaker (P<0.01). 3 months after discharge, there was no significant difference in the effects between the muscular energy group (83.3%) and the block therapy group (91.7%) (P>0.05); 6 months after discharge, the muscular energy group (75.0%) was better than the block therapy group (46.1%) (P<0.01); 1 year after discharge,the muscular energy group (54.2%) was better than the block therapy group (16.7%) (P<0.01). Conclusion The block therapy is better in short-term effect on humeral epicondylitis, and the muscle energy technique was better in long-term effect.
