Effect Of Different Frequency Of Electroacupuncture On Muscle Contraction Of Rabbit Skeletal Muscle

Objective:By observing under different frequency electroacupuncture rabbits gastrocnemius muscle during contraction state,is calculated under different muscle motion frequency of electric acupuncture,to define the curative in low frequency range,including speculated that different frequency range is suitable for the types of diseases,which will play better in clinical utility.Methods:To detect the maximum output frequency of all the brands that can be collected,select the highest frequency to reach 1000 Hz for the experiment.Use healthy rabbit rabbit fixed frame is fixed,double hind legs bound to straighten out,bilateral calves use depilate cream unhairing,select "after three mile" on both sides,regular disinfection,sterile acupuncture needles into acupuncture points 15 mm,connected to electric acupuncture apparatus.Connect with acupuncture points of electric acupuncture apparatus on the conductor of a 100 series ? resistance box,and then from the resistance box on both ends of a pair of wires connected to the input end of the oscilloscope.The cupping apparatus output intensity and the output frequency,observe the rabbit calf muscles during contraction state,including oscilloscope for monitoring instrument output frequency at the same time,continuous output slowly from the 1Hz to 1000 Hz,the observation record and video.Set a fixed frequency around the frequency window of the change in motion state,and carefully observe the specific frequency that causes the movement to change.Repeat the experiment with multiple rabbits.Result:Under fixed electric needle stimulation,1.When the frequency of the electroacupuncture is in the condition of 15-16 Hz,it can be seen that the muscles of the skeletal muscle of the rabbit are obvious and the vibration is stronger.2.When the 16Hz< electroacupuncture frequency of 128 Hz,the muscle tremor of the rabbit skeletal muscle weakened,the strength contraction increased,and the maximum intensity was forced to contract at 100 Hz.?3.When the 128 hz frequency of electric acupuncture 512 Hz,The muscle of the rabbit gradually relaxed to the natural state,and the spasmodic contraction gradually decreased,to 512 Hz,the muscle was in a natural state,and the spasmodic contraction disappeared.4.When 512Hz< the output frequency of the electroacupuncture is 1000 Hz,the muscle was in a natural state,the skeletal muscle of the rabbit is not contracted.Conclusion:Through the experiment,found that under the fixed electroacupuncture intensities,different frequency of electricity for muscle movement,including to speculate that different frequency range by appropriate disease,used to guide the clinical,to improve the therapeutic effect of electric acupuncture,and can further promote the development of electric acupuncture apparatus.
