Few studies have considered the effects of percutaneous electrolysis (PE) in the treatment of lateral epicondylalgia (LE). For this reason, the objective of this study was to compare the effects of PE with an evidence-based approach-trigger point dry needling (TDN)-in patients with LE. A randomized controlled trial was conducted in which 32 participants with LE were randomly assigned to two treatment groups, the PE group ( = 16) and the TDN group ( = 16). Both groups received four therapy sessions and an eccentric exercise program to be performed daily. The numerical pain rating scale (NPRS), pressure pain thresholds (PPT), quality of life, and range of motion were measured before treatment, at the end of treatment, and at one- and three-month follow-ups. Significant between-group mean differences were found after treatment for NPRS ( < 0.001) and flexion movement ( = 0.006). At one-month follow-up, significant mean differences between groups were found for NPRS ( < 0.001), PPT ( = 0.021), and flexion ( = 0.036). At three-months follow-up, significant mean differences between groups were found for NPRS ( < 0.001), PPT ( = 0.004), and flexion ( = 0.003). This study provides evidence that PE could be more effective than TDN for short- and medium-term improvement of pain and PPTs in LE when added to an eccentric exercise program.
很少有研究考虑经皮电解（PE）在治疗肱骨外上髁炎（LE）中的作用。因此，本研究的目的是比较PE与循证方法——触发点干针疗法（TDN）——对LE患者的治疗效果。进行了一项随机对照试验，32名LE患者被随机分为两个治疗组，PE组（ = 16）和TDN组（ = 16）。两组均接受四个疗程的治疗，并进行每日的离心运动训练。在治疗前、治疗结束时、1个月和3个月随访时测量数字疼痛评分量表（NPRS）、压痛阈值（PPT）、生活质量和关节活动范围。治疗后，NPRS（ < 0.001）和屈曲运动（ = 0.006）在组间均值上存在显著差异。在1个月随访时，组间NPRS（ < 0.001）、PPT（ = 0.021）和屈曲（ = 0.036）存在显著均值差异。在3个月随访时，组间NPRS（ < 0.001）、PPT（ = 0.004）和屈曲（ = 0.003）存在显著均值差异。本研究提供了证据，表明在进行离心运动训练的基础上，PE在短期和中期改善LE患者的疼痛和压痛阈值方面可能比TDN更有效。
