低频电治疗腰肌劳损疗效观察

Low frequency electricity treatment strain of lumbar muscles curative effect observation

目的：观察50Hz交流正弦电流低频治疗单级法与50-100Hz 低频治疗并置法对腰肌劳损治疗效果的临床观察.方法：将60例腰肌劳损患者患者随机分为治疗组与对照组=组,治疗组以50Hz交流正弦波,脉冲持续为10ms,单极法阴极置于痛点,阳极置于腹部,对照组50Hz-100Hz交流电,脉冲持续10ms.双极并置腰部痛点.5天为一疗程,五天后评价疗效.结果：两组患者疗效比较,治疗组优于对照组,差异有统计学意义（P＜0.01）,治疗后两组疼痛均有改善,治疗组疼痛改善优于对照组（P＜0.05）.结论：50Hz低频电治疗腰肌劳损缓解疼痛的有效率高于50Hz-100Hz.

Objective：Observes the 50Hz exchange sinusoidal current low frequency treatment single and the 50--] 00Hz low fre- quency treatment juxtaposition law to the strain of lumbar muscles treatment result clinical observation. Methods： Stochastically divides into the treatment group and the control group = group 60 example strain of lumbar muscles patient patient, the treatment group take the 50 Hz exchange sine wave,the pulse continues as 10ms, the single--pole law negative pole puts in the pain spot, the anode puts in the abdomen, the control group 50Hz--100Hz alternating current, the pulse continues 10ms. Double--pole juxtaposi- tion waist pain spot. 5 days are a treatment course,after five days appraise the curative effect. Results：Two group of patient curative effect comparison,the treatment group surpasses the control group, the difference has statistics significance （P〈0.01）, treats the latter two groups of aches to have the improvement,the treatment group ache improvement surpasses the control group （P〈0.05）. Conclusioa：50Hz low frequency electricity treatment strain of lumbar muscles alleviation ache effectiveness is higher than 50Hz --100Hz.
