The aims of this double-blind, randomized, placebo-controlled trial were to determine whether ultrasound-guided extracorporeal shock wave therapy (ESWT) reduced pain and improved function in patients with lateral epicondylitis (tennis elbow) in the short term and intermediate term.
Sixty-eight patients from community-based referring doctors were randomized to receive 3 ESWT treatments or 3 treatments at a subtherapeutic dose given at weekly intervals. Seven outcome measures relating to pain and function were collected at followup evaluations at 6 weeks, 3 months, and 6 months after completion of the treatment. The mean changes in outcome variables from baseline to 6 weeks, 3 months, and 6 months were compared for the 2 groups.
The groups did not differ on demographic or clinical characteristics at baseline and there were significant improvements in almost all outcome measures for both groups over the 6-month followup period, but there were no differences between the groups even after adjusting for duration of symptoms.
Our study found little evidence to support the use of ESWT for the treatment of lateral epicondylitis and is in keeping with recent systematic reviews of ESWT for lateral epicondylitis that have drawn similar conclusions.
本双盲、随机、安慰剂对照试验的目的是确定超声引导下体外冲击波疗法（ESWT）在短期和中期是否能减轻外侧上髁炎（网球肘）患者的疼痛并改善其功能。
来自社区转诊医生处的68例患者被随机分为接受3次ESWT治疗组或每周接受1次亚治疗剂量治疗共3次的治疗组。在治疗结束后6周、3个月和6个月的随访评估中收集了7项与疼痛和功能相关的结局指标。比较了两组从基线到6周、3个月和6个月结局变量的平均变化。
两组在基线时的人口统计学或临床特征无差异，在6个月的随访期内两组几乎所有结局指标均有显著改善，但即使在调整症状持续时间后两组之间也无差异。
我们的研究几乎没有证据支持使用ESWT治疗外侧上髁炎，这与最近关于ESWT治疗外侧上髁炎的系统评价得出的类似结论一致。
