目的：观察运用内热针治疗纤维肌痛综合征（FMS）的临床疗效。方法：选择FMS患者60例作为研究对象，按照随机数字表法分为观察组和对照组各30例。对照组采用普通针刺治疗，观察组给予内热针治疗，观察两组患者治疗前、治疗后、治疗后3个月视觉模拟评分法（VAS）、修订版FMS影响问卷调查表（FIQR）、汉密尔顿抑郁量表（HAMD）评分变化情况；对各时间点所采集的数据进行统计分析处理，观察治疗前后组间、组内变化，进行临床疗效比较。结果：(1)研究过程中，观察组失访2例，剔除1例，对照组剔除1例，脱落1例。最终观察组27例、对照组28例纳入疗效统计。(2)观察组总有效率为88.9%，对照组为71.4%，观察组临床疗效优于对照组，差异有统计学意义（P<0.05）。(3)全部疗程结束后，两组患者的VAS评分均较治疗前下降（P<0.05），但组间比较差异无统计学意义（P=0.683）。(4)治疗后两组患者HAMD评分均较治疗前降低（P<0.05），观察组HAMD评分低于对照组（P<0.05）。(5)治疗后两组患者FIQR评分均较治疗前降低（P<0.05），且观察组低于对照组（P<0.05）。(6)3个月后随访数据显示，两组患者VAS评分、HAMD评分、FIQR评分均较治疗前降低（P<0.05），且观察组以上三项指标的维持效果均优于对照组（P<0.05）。(7)治疗结束3个月后，观察组复发率为11.11%，低于对照组（28.57%），差异有统计学意义（P<0.05）。结论：内热针应用于FMS治疗，可有效减轻患者疼痛症状，改善躯体功能障碍、情绪障碍、睡眠障碍，临床疗效显著，预后更佳。

Objective:To observe the clinical efficacy of internal heat acupuncture in the treatment of fibromyalgia syndrome(FMS). Methods:Sixty patients with FMS were selected as the study subjects and randomly divided into an observation group and a control group using the random number table method,30 cases in each group. The control group received conventional acupuncture treatment,while the observation group was treated with internal heat acupuncture. Changes in the visual analogue scale(VAS),the revised fibromyalgia impact questionnaire(FIQR),and the Hamilton depression rating scale(HAMD) scores were observed in both groups before treatment,after treatment,and 3 months after treatment. Statistical analyses were performed on the data collected at each time point to evaluate within-group and between-group changes and to compare clinical efficacy. Results:(1)During the study,2 cases in the observation group were lost to follow-up and 1 case was excluded;in the control group,1 case was excluded and 1 case dropped out. Ultimately,27 patients in the observation group and 28 in the control group were included in the efficacy analysis.(2)The total effective rate was 88.9% in the observation group and 71.4% in the control group. The clinical efficacy of the observation group was superior to that of the control group,and the difference was statistically significant(P<0.05).(3)After completion of the full treatment course,the VAS scores in both groups were significantly lower than those before treatment(P<0.05),but there was no statistically significant difference between the two groups(P=0.683).(4)After treatment,the HAMD scores in both groups were significantly reduced compared with those before treatment(P<0.05),and these in the observation group were lower than those in the control group(P<0.05).(5)After treatment,the FIQR scores in both groups were significantly lower than those before treatment(P<0.05),and these in the observation group were lower than those in the control group(P<0.05).(6)Follow-up data at 3 months showed that the VAS,HAMD,and FIQR scores in both groups remained significantly lower than those before treatment(P<0.05),and the observation group demonstrated better maintenance effects than the control group in all three indicators(P<0.05).(7)Three months after the end of treatment,it showed that the recurrence rate in the observation group(11.11%) was lower than that in the control group(28.57%),with a statistically significant difference(P<0.05). Conclusions:Internal heat acupuncture can effectively alleviate pain symptoms in patients with FMS and improve physical dysfunction,emotional disturbance,and sleep disturbance. It shows significant clinical efficacy and yields a better prognosis.
