【摘要】 目的:观察低频脉冲电磁场(PEMFs)治疗骨质疏松症慢性疼痛的临床疗效。方法:20例志愿受试者均为绝经女性,具有明显骨质疏松症疼痛,4例伴有OP脆性骨折,骨密度降低程度符合WHO的OP诊断标准。采用低频脉冲电磁场,功率≤2000VA;脉冲频率1Hz至100Hz可调;磁感应强度1至50Hz区间:0至100Gs可调,51Hz至100Hz区间:0至75Gs可调。单独采用低频脉冲电磁场治疗,停用其他治疗。将治疗环移至病变部位或疼痛部位,每次治疗30至40分钟,每日一次,20至30次为一疗程。疗程结束后,进行自身前后配对T检验,对VAS、骨密度结果进行统计学处理,判断治疗效果。结果:治疗前后VAS均数为5.85、3.25,标准差1.53、0.79,T值6.50,P<0.001;骨密度治疗前后无显著性差异,T值1.33,P>0.05。结论:低频脉冲电磁场能够明显缓解OP慢性疼痛,是OP的有效物理治疗方法,无不良反应发生。骨密度变化无显著性差异与观察时间短、骨质改变慢等因素有关。更多还原

【Abstract】 Objective: In order to study the effect of low-frequency pulsed electromagnetic field on the pain in osteoporosis.Methods: 20 postmenopausal women suffering from pain, who were diagnosed as osteoporosis according to the WHO standard,mean age was 65.2(range 50-79), were included in this trial. These patients suffered from osteoporotic pain at least 6 months,and the mean course of disease was 5.12 years. 4 patients had osteoporotic fracture. All patients only received the low-frequency pulsed electromagnetic field therapy with ZH-21 osteoporosis treatment system( Power ≤ 2000VA; Pulsed Frequency:1-100Hz;Magnetic Induction: 0-100Gs with pulsed frequency 1-50Hz, 0-75Gs with pulsed frequency 51-100Hz). A total of 20-30 managements, with 30-40 min at a time and once per day, were given to the patients. The VAS and the bone mineral density were tested in the post-therapy period compared to pre-therapy. Results: The VAS was 5.85±1.53 pre-therapy, and significantly decreased to3.25±0.79 in the post-therapy period. No significant difference was found in the bone mineral density between the pre-therapy and post-therapy. Conclusion: Our study demonstrated that ZH-21 osteoporosis treatment system can release the osteoporotic pain,and have no adverse side effect. But no significant difference was found in the bone mineral density, which related to the short observation time, etc.更多还原
