简要总结
Percutaneous electrolysis is a minimally invasive approach that consists in the application of a galvanic current through an acupuncture needle. Although several mechanisms and effects are attributed to percutaneous electrolysis, currently there are only a few publications that delve into this topic. The aim of this study is to investigate the influence of percutaneous electrolysis on the endogenous pain modulation. Four groups of intervention will be involved: no-intervention, isolated needling procedure, low intensity percutaneous electrolysis and high intensity percutaneous electrolysis. The effects on the pain modulation system will be evaluated before and immediately after the intervention, through pressure pain thresholds, conditioned pain modulation and temporal summation.

结局指标
主要结局
Change from baseline Conditioned Pain Modulation (evaluated by pressure algometry) immediately after the intervention
时间窗: Baseline and immediately after the intervention
Assessed by algometry. Conditioning stimulus: pressure cuff on the arm. Measured at three locations (bilaterally): common extensor tendon of the epicondyle, cervical spine and tibialis anterior muscle.
次要结局
- Change from baseline Pressure Pain Thresholds immediately after the intervention(Baseline and immediately after the intervention)
- Change from baseline Temporal Summation (evaluated by VNRS) immediately after the intervention(Baseline and immediately after the intervention)
