A randomized double blind multi-center study of electric stimulation compared with sham units enrolled 59 patients (67 wounds) with open wounds of pressure, vascular and surgical etiology at nine sites. The 14-week study consisted of a four-week phase, randomized, parallel-group, double blind, sham stimulation controlled group comparing effectiveness and tolerance of electric and sham stimulation of open wounds. Patients with wounds not completely closed at the end of the four weeks were allowed to cross over to actual treatment. After four weeks of treatment, the electric stimulation group showed a 56% decrease in size with only a 33% decrease in size with sham treatment. Available data suggest that pulsed electric stimulation should be considered by health care practitioners as an adjunct for treating open wounds.
一项关于电刺激与假刺激装置对比的随机双盲多中心研究，纳入了9个地点的59例患者（67处伤口），这些伤口由压力、血管及手术病因导致且为开放性伤口。这项为期14周的研究包括一个为期四周的阶段，该阶段为随机、平行组、双盲、假刺激对照试验，对比开放性伤口电刺激与假刺激的有效性和耐受性。四周结束时伤口未完全愈合的患者可转为接受实际治疗。治疗四周后，电刺激组伤口面积减小了56%，而假刺激治疗组仅减小了33%。现有数据表明，医疗从业者应考虑将脉冲电刺激作为治疗开放性伤口的辅助手段。
