【摘要】：目的:建立表征触发点活性的客观性量化指标,并尝试利用该指标实现干针和被动牵张疗法对肌筋膜疼痛触发点疗效的定量评价。方法:SD大鼠随机分为空白组、干针组、牵张组和干针牵张组,每组6只。采用打击结合离心运动方法对大鼠左下肢腓肠肌部位进行触发点造模,造模8周,自然恢复4周,定位触发点位置并记录肌电信号。第13周进行1次治疗,记录治疗后6min触发点的肌电信号。干针组进行干针治疗,牵张组对其左侧腓肠肌进行被动缓慢牵张,干针牵张组先进行干针治疗随后进行被动牵张锻炼。采用肌电信号序列的样本熵估计触发点活性,进行疗效分析。结果:(1)造模周期结束后,空白组肌电信号样本熵均值(0.985±0.196)高于干针组(0.034±0.010)、牵张组(0.045±0.023)和干针牵张组(0.047±0.034)均(P0.01)。(2)治疗后干针组(0.819±0.088)、牵张组(0.532±0.205)、干针牵张组(0.810±0.117)肌电信号样本熵估计均上升(均P0.01)。(3)牵张组治疗后样本熵估计低于干针组和干针牵张组(P0.01)。结论:肌电信号样本熵作为触发点活性评价的客观性指标具有较好的一致性和灵敏度;干针、牵张、干针结合牵张对大鼠触发点均有一定疗效,干针治疗短期疗效显著,明显优于单一被动牵张治疗,能迅速降低大鼠肌筋膜触发点活性。
[Abstract]:Objective: to establish an objective quantitative index to characterize the activity of the trigger point and to evaluate the therapeutic effect of dry acupuncture and passive stretch therapy on the trigger point of myofascial pain. Methods: the rats were randomly divided into blank group and dry needle group. There were 6 rats in each group in distraction group and 6 in dry needle group. The trigger point of gastrocnemius muscle of left lower extremity was made by means of strike combined with centrifugal exercise. The model was made for 8 weeks and recovered naturally for 4 weeks. The position of trigger point was located and EMG signal was recorded. After 13 weeks treatment, the electromyography (EMG) of trigger point was recorded 6 minutes after treatment. The dry needle group was treated with dry acupuncture, and the left gastrocnemius muscle of the distraction group was subjected to passive and slow distraction. Dry needle stretch group was treated with dry acupuncture first and then passive stretch exercise. The activity of trigger point was estimated by sample entropy of EMG signal sequence, and the curative effect was analyzed. The mean entropy of EMG samples in the blank group (0.985 卤0.196) was higher than that in the dry needle group (0.034 卤0.010), the distraction group (0.045 卤0.023) and the dry needle distraction group (0.047 卤0.034) respectively (P 0.01 卤0.088).) after treatment, the entropy estimates of EMG samples in the dry needle group (0.819 卤0.088), the distraction group (0.532 卤0.205) and the dry needle distraction group (0.810 卤0.117) were significantly increased (P < 0.01. 0. 3). The estimation of sample entropy was lower than that of dry needle group and dry needle stretch group (P 0.01). Conclusion: the sample entropy of EMG signal as the objective index of activity evaluation of trigger point has good consistency and sensitivity. Dry needle, distraction, dry needle combined with distraction have certain curative effect on the trigger point of rats. The short-term curative effect of dry acupuncture treatment is obvious, which is obviously superior to that of single passive distraction therapy, and can rapidly reduce the activity of the trigger point of muscle fascia in rats.
