Of 76 patients with lateral epicondylitis, 38 were randomly allocated to receive ultrasound treatment and 38 placebo. All 76 were given 12 treatments each over four to six weeks. The conditions of 24 patients (63%) treated with ultrasound and 11 (29%) given placebo improved, the difference being significant at the 1% level. Improvement in particular clinical variables (pain score, weight lifting, grip strength) also showed an advantage for the patients given ultrasound treatment. A simple underwater radiation balance showed considerable fluctuation in ultrasonic output, and frequent checks of output were shown to be necessary. Ultrasound enhances recovery in most patients with lateral epicondylitis.
在76例患有外侧上髁炎的患者中，38例被随机分配接受超声治疗，38例接受安慰剂治疗。所有76例患者均在四至六周内接受了12次治疗。接受超声治疗的24例患者（63%）和接受安慰剂治疗的11例患者（29%）病情有所改善，差异在1%水平上具有显著性。特定临床变量（疼痛评分、举重能力、握力）的改善也显示超声治疗组患者具有优势。简单的水下辐射平衡显示超声输出有相当大的波动，且有必要经常检查输出。超声可促进大多数外侧上髁炎患者的恢复。
