Twenty pairs of patients matched for sex, age, weight, and degree of trauma were treated either with an active Diapulse machine emitting pulsed, high-frequency electrical energy or with a non-active placebo machine. They were examined for swelling, pain, and disability before treatment and after three days under double-blind conditions. The results show that the pulsed, high-frequency electrical treatment has a definite biological effect on recently injured soft tissues, especially in the reduction of pain and disability.
选取了20对在性别、年龄、体重和创伤程度上相匹配的患者,分别用一台发射脉冲高频电能的有源Diapulse仪器或一台无源安慰剂仪器进行治疗。在双盲条件下,于治疗前及治疗三天后对他们进行了肿胀、疼痛和残疾情况检查。结果表明,脉冲高频电疗对近期受伤的软组织具有明确的生物学效应,尤其是在减轻疼痛和残疾方面。
