低频脉冲电磁场治疗骨质疏松症的临床观察

Clinical observation of low-frequency pulse electromagnetic field on treatment of osteoporosis

目的骨质疏松症是一种表现为疼痛、病理性骨折的一类常见骨病。骨质疏松症的治疗受到临床各科室的重视。低频脉冲电磁场是一种运用于治疗骨质疏松症的新方法，为此探讨运用低频脉冲电磁场治疗原发性骨质疏松症的一些规律。方法对2005～2006年间，我科门诊收治的41名骨质疏松症患者进行低频脉冲电磁场治疗，观察其对疼痛和骨密度的作用。结果经过每周6次，连续30次的治疗，患者在4．8±0．286天开始疼痛缓解，一周后疼痛缓解36．3％±3．7％（P=0．00），30天后疼痛缓解87．0％±2．1％（P=0．00）；3个月后骨密度提高2．6％±4．4％（P：0．099）。结论低频脉冲电磁场可以有效缓解骨质疏松症相关疼痛；而对骨密度改善可能有疗效，这需进一步实验提供更为可靠的证据。

Objective To observe the effect of low-frequency pulse electromagnetic field （PEMFs） on the treatment of osteoporosis. Methods Forty-one osteoporosis patents from 2005 to 2006 were treated by PEMFs in the out-patients department,6 times a week and 30 times in all. All patients were requested to record the time when they felt better. And the pain assessment was performed at the 7^th and 30^th days after the therapy and the BMD was examined 3 months after. Results The pain was started to recover at 4.8 ± 0.286 days averagely and the rate of pain relieve was 36.3%± 3.7% （ P 〈 0.01 ） after 7 days and 87.0% ± 2.1% （ P 〈 0.01 ） after 30 days. The BMD increased by 2.6% ± 4.4% （ P = 0. 099 ） after 3 months. Conclusions PEMFs can relieve the pain associated with osteoporosis effectively and also increase the BMD, however, the latter requires further researches.
