Intermediate frequency therapy and acupuncture have similar effects. Mainly uses the frequency of 2000- 10000 Hz to stimulate the acupoints to achieve the physical therapy effect. Electrical pulses are mainly used to stimulate human meridians and promote blood circulation in the body, just like acupoints. If it is convenient to use an intermediate frequency therapeutic instrument at home, you don't need to go to the hospital for acupuncture? We use the intermediate frequency therapeutic instrument of Bei Yikang at home, which has a great effect.
