To determine the effectiveness of high voltage pulsed current (HVPC) in reducing chronic hand edema, 120 individuals were randomly assigned to one of two treatment groups. Group I clients were given an appropriate sized wrist splint, incorporating an energized, high voltage pulsed unit. Group II clients were given an identical splint with a non-energized unit. Each client received daily treatments at the worksite consisting of 30 minute sessions totaling 20 treatments during a 35 day period. Pre-treatment and post-treatment evaluations included measurements of pain, grip strength, and edema volume; repetitive task testing; and Semmes-Weinstein Monofilament sensory testing. In the energized group, post-treatment evaluation showed statistically significant decreases in the amount of stimulation required to stimulate the median nerve and the amount of hand edema and pain. The energized group also had improved repetitive task times. None of these improvements occurred in the non-energized group. Based on these results, HVPC appears to be an effective method for minimizing the severity of repetitive stress injuries of the wrist.
为了确定高压脉冲电流（HVPC）在减轻慢性手部水肿方面的有效性，120名个体被随机分配到两个治疗组中的一组。第一组患者被给予一个尺寸合适的手腕夹板，其中包含一个通电的高压脉冲装置。第二组患者被给予一个带有未通电装置的相同夹板。每位患者在工作场所接受每日治疗，每次治疗时长30分钟，在35天内共进行20次治疗。治疗前和治疗后的评估包括疼痛、握力和水肿体积的测量；重复性任务测试；以及Semmes-Weinstein单丝感觉测试。在通电组中，治疗后评估显示，刺激正中神经所需的刺激量、手部水肿量和疼痛在统计学上有显著下降。通电组的重复性任务时间也有所改善。在未通电组中，这些改善均未出现。基于这些结果，高压脉冲电流似乎是一种有效减轻手腕重复性应力损伤严重程度的方法。
