目的探讨不同热刺激时间对腰痛的影响。方法将40名受试者随机分为不同加热时间的4组。短加热时间组（SL）、中加热时间组（ML）、长加热时间组（LL）分别给予15、30、60 min的灌源穴灸疗（cv4）。常规针刺组（CA）以针刺治疗为对照组。参与者在为期2周的治疗期内连续接受治疗，共10次治疗，每周5次。参与者每周接受盲法评估，采用视觉模拟量表（VAS）和罗兰莫里斯问卷（RMQ）。结果四组患者治疗期间VAS评分和RMQ评分均降低。治疗前与治疗2周后，LL组VAS评分、RMQ评分差异均有统计学意义（P< 0.01）。治疗后，LL组VAS评分明显低于CA组、ML组、SL组（P< 0.05）。结论较长和中等长度的热刺激时间（30和60 min）比短时间的热刺激更能有效缓解腰痛。
ObjectiveTo investigate the effect of different heat-stimulating time lengths on lower back pain.MethodsForty participants were randomly assigned to four groups of various heating time lengths. The short heating time length group (SL), moderate heating time length group (ML), and long heating time length group (LL) respectively received 15, 30, and 60 min of moxibustion therapy stimulating the acupoint Guanyuan (CV 4). The conventional acupuncture group (CA) received needle acupuncture treatment as a control group. The participants were treated continuously over a 2-week treatment period for a total of 10 sessions, with five sessions given per week. Participants were assessed weekly by blinded assessors, using the visual analogue scale (VAS) and Roland Morris Questionnaire (RMQ).ResultsThe VAS and RMQ scores reduced in all four groups during treatment. There were significant differences in VAS scores (P< 0.01) and RMQ scores (P< 0.01) between before treatment and after 2 weeks of treatment in the LL group. After treatment, the LL group reported significantly lower VAS scores compared with the CA group, ML group, and SL group (P< 0.05).ConclusionThe long and moderate lengths of heat-stimulating time of 30 and 60 min may be more effective for relieving lower back pain than that of short stimulating time lengths.
