The technology of electrotherapy is to stimulate the body through current, so that the local qi and blood of the body can react and promote recovery, which is somewhat similar to acupuncture, but the magnitude, frequency and time of current will have a great impact on the therapeutic effect, and this external stimulation is harmful to the body, and the overall effect is actually not as good as acupuncture. Anyone who has used electrotherapy to treat facial paralysis knows that it is easier to get acne, which is an unbalanced performance. In the absence of good acupuncturists and Chinese medicine, electrotherapy is also a helpless move.
