低频脉冲电磁场治疗高龄骨关节疼痛效果研究

Effect research of low frequency pulsed electromagnetic fields on pain of bone and joint in elderly patients

目的探讨低频脉冲电磁场治疗老年骨关节疼痛的临床疗效。方法选取150例老年骨关节疼痛患者进行研究,并根据老年患者骨关节疼痛的病症分为三组:以骨质疏松症为主的50例为A组、以骨性关节炎为主的50例为B组、以股骨头缺血性坏死为主的50例为C组。对三组患者都采用低频脉冲电磁场进行治疗,治疗过程中采用扫描模式,频率每4分钟就需要变化1档。每周5次,每次30 min。持续治疗15次后休息1周,然后继续接受治疗。4周1疗程,所有患者均连续治疗3个疗程。观察三组患者的疼痛强度、疼痛缓解程度与临床实验室检查结果。结果三组治疗第4、12周的疼痛强度均明显低于较治疗前,差异均有统计学意义(t分别=5.58、5.23、5.15、4.79、6.23、5.33,P均<0.05)。治疗结束后的第4周,A、B两组疼痛强度均较治疗前明显下降,差异均有统计学意义(t分别=5.13、5.87,P均<0.05),但C组未出现明显改变,差异无统计学意义(t=1.21,P均>0.05)。三组患者经过12周的治疗后,A组、B组和C组总缓解率分别为90.00%、92.00%和70.00%。A、B两组总缓解率均明显高于C组,差异均有统计学意义(χ2分别=6.12、5.79,P均<0.05)。三组患者经过治疗后,对其生命体征与实验室检查,各指标与治疗前比较,差异均无统计学意义(t分别=0.27、2.01、1.52、2.03、1.12、1.13、3.15;1.79、2.11、3.10、3.15、0.89、1.09、1.13;0.97、0.96、1.23、1.15、2.03、2.56、2.05,P均>0.05)。结论采用低频脉冲电磁场对不同原因所导致的骨关节疼痛老年患者进行治疗可以获得良好的效果,且安全性高。

Objective To explore the clinical effect of low-frequency pulsed electromagnetic fields on bone and joint pain in the elderly. Methods A total of 150 cases of elderly patients with pain of bone and joint were selected and divid-ed into three groups that 50 cases of osteoporosis as A group, 50 cases of osteoarthritis as B group and 50 cases of avascu-lar necrosis of the femoral head as C group according to the pain of bone and joint disease. Three groups were given low frequency pulse electromagnetic field treatment and chose the scanning mode, the frequency was 4 minutes per file, 5 times a week, 30 minutes each time. Rest for 1 week after continuous treatment 15 times, and then continue to treatment. 4 weeks as a course, the whole treatment course was 3. The pain intensity, degree of pain relief and clinical laboratory test results of the three groups were observed. Results The pain intensity of three groups at 4th,12th week in treatment were significantly lower than those before treatment（t=5.58,5.23,5.15,4.79,6.23,5.33,P〈0.05）. At 4th week after thera-py accomplished, the pain intensity of A group and B group were significantly decreased than before treatment （t=5.13, 5.87,P〈0.05） while there was no significant difference in C group （t=1.21,P〉0.05）. After 12 weeks of low-frequency pulsed electromagnetic field treatment, the total remission rates of three groups were 90%, 92%and 70%respectively. The total remission rates of A group and B group were significantly higher than C group （χ2=6.12,5.79,P〈0.05）. The differ-ences of vital signs and laboratory examination indexes before and after treatment were not statistically significant （t=0.27,2.01,1.52,2.03,1.12,1.13,3.15;1.79,2.11,3.10,3.15,0.89,1.09,1.13;0.97,0.96,1.23,1.15,2.03,2.56,2.05,P〉0.05）. Conclusion The patients with bone and joint pain can obtain good effect and high safety through low frequency pulsed electromagnetic fields.
