针刀松解腘绳肌对膝骨性关节炎兔膝周肌群表面张力的影响

Effect of Acupotomy Loosening Hamstring on Tissue Tension of Knee Muscles of Rabbits with Knee Osteoarthritis Muscle

目的:探讨针刀松解腘绳肌对膝骨性关节炎兔膝周肌群表面张力的影响。方法:将28只实验兔随机分为空白组,模型组,电针组及针刀组,每组7只,采用左后肢伸直位造模法制动8周,空白组及模型组随机挑选1只进行光镜观察,以验证模型是否成功,造模成功后,针刀组及电针组进行干预,共3周。然后将软组织张力计置于股二头肌、半腱半膜肌、股直肌、腓肠肌的肌腹与肌肉肌腱移行处分别测量力-位移值。结果:与空白组比较,模型组各点均有降低趋势,除股二头肌点外,其他点差异均有统计学意义(P<0.05)。与模型组比较,电针组各点出现升高趋势,股二头肌与半腱半膜肌的肌肉肌腱移行处差异有统计学意义(P<0.05)。针刀组各点均有升高,除腓肠肌点(肌肉肌腱移行处)外,其他点差异均有统计学意义(P<0.05)。与电针组比较,针刀组各点均有升高,除股二头肌点(肌肉肌腱移行处)外,其他点差异均有统计学意义(P<0.05)。结论:针刀松解腘绳肌可以有效降低膝周肌群表面张力。

Objective:To investigate the effect of acupotomy loosening hamstring method on tissue tension of knee muscles of rabbits with knee osteoarthritis muscle.Methods:Twenty-eight experimental rabbits were randomly divided into 4 groups:electro-acupuncture therapy group,acupotomy therapy group,model group and blank group,with 7 rabbits per group.After eight weeks of left hind limb extension position modeling method,1 rat in the blank group and model group were randomly selected for light microscope observation to verify the success of the modeling.After successfully modeling,electro-acupuncture therapy group and acupotomy therapy group were intervened for 3 weeks.Then,the soft tissue tension meter was placed on the muscular abdomen and the muscular tendon transition of the biceps femoris,semitendinosus semimembranosus,rectus femoris,and gastrocnemius muscles,and the force-displacement values was measured respectively.Results:Compared with the blank group,all points in the model group had a decreasing trend,except for the biceps femoris points,the other points had statistical significance(P<0.05).Compared with the model group,the electro-acupuncture group showed an increasing trend in each point,and the muscular tendon transition of the biceps femoris and semitendinosus semimembranosus was statistically significant(P<0.05).All points in the acupotomy group were increased,except for the gastrocnemius point(the muscular tendon transition),other points were statistically significant(P<0.05).Compared with the electro-acupuncture group,all points in the acupotomy group were increased,except for the biceps femoris(he muscular tendon transition),other points were statistically significant(P<0.05).Conclusion:acupomoty release hamstring muscle method can effectively reduce the surface tension of the knee muscles.
