The aim of this study was to establish if the changes in sympathetic and parasympathetic activity (analyzed through heart-rate variability [HRV]) during ultrasound (US)-guided percutaneous needle electrolysis (PNE) is due to the effect of needle puncture only or of the PNE technique per se where the puncture and galvanic current are combined.
This was an experimental, case-control study that took place at the University of Seville. Subjects were 36 male footballers who were randomly allocated to three groups: a control group (CG; 12 players), for whom HRV was recorded for 10 min, both at rest and during an exhaustive US examination of the patellar tendon and adjacent structures; a first experimental group (PNE group; 12 players), for whom HRV was recorded for 10 min, both at rest and during application of US-guided PNE in the patellar tendon; and a second experimental group (needle group; 12 players), for whom HRV was recorded for 10 min, both at rest and during application of US-guided PNE without electrical current in the patellar tendon. The outcome measures were the diameters of the Poincaré plot (SD1, SD2), stress score, and sympathetic/parasympathetic ratio.
There were no differences between groups in any baseline measurements, nor were there any significant differences between CG measurements (baseline vs. intervention). The PNE group exhibited statistically significant increases in SD1 (p = 0.01) and SD2 (p = 0.004) and statistically significant decreases in SS and S/PS ratio (p = 0.03), indicating increased parasympathetic and decreased sympathetic activity, respectively. The needle group exhibited statistically significant increases in SD2 (p = 0.02) and statistically significant decreases in SS (p = 0.02), indicating decreased sympathetic activity.
The application of the US-guided PNE technique caused a measurable increase in parasympathetic activity (detected by HRV), which was due to the combination of needle puncture and electric current.
本研究旨在确定在超声（US）引导下经皮穿刺电解术（PNE）过程中交感神经和副交感神经活动的变化（通过心率变异性[HRV]分析）是仅由针刺的影响引起，还是由PNE技术本身（其中穿刺和电流相结合）导致。
这是一项在塞维利亚大学进行的实验性病例对照研究。受试者为36名男性足球运动员，他们被随机分为三组：对照组（CG；12名运动员），在静息状态以及对髌腱和相邻结构进行全面超声检查期间记录其HRV 10分钟；第一个实验组（PNE组；12名运动员），在静息状态以及对髌腱进行US引导下的PNE操作期间记录其HRV 10分钟；第二个实验组（针刺组；12名运动员），在静息状态以及对髌腱进行无电流的US引导下的针刺操作期间记录其HRV 10分钟。观察指标为庞加莱图直径（SD1、SD2）、应激评分以及交感/副交感神经比率。
各实验组在任何基线测量方面均无差异，CG组的测量值（基线与干预后）之间也无显著差异。PNE组的SD1（p = 0.01）和SD2（p = 0.004）有统计学显著增加，应激评分（SS）和交感/副交感神经比率（S/PS）有统计学显著降低（p = 0.03），分别表明副交感神经活动增加和交感神经活动减少。针刺组的SD2有统计学显著增加（p = 0.02），SS有统计学显著降低（p = 0.02），表明交感神经活动减少。
US引导下的PNE技术应用导致副交感神经活动出现可测量的增加（通过HRV检测），这是由针刺和电流的联合作用引起的。
