To further strengthen this comparison, since the last 60 years, scientific discoveries found that 99% of points correspond with many nerve endings and more than 70% of the acupuncture points correspond to trigger points, i.e. points quite sore to pressure, even in a normal state.
When inserting a needle in the point, the doctor expects to get the feeling of “Qi”, referred to by patients as being a feeling of numbness, heaviness, burning, pain and even discreet pruritus (itching). These different sensations are a result of the needles touching the endings of thin and medium caliber nerves.
This concept is reinforced by the verification of reduction or even loss of the ability of perception “Qi” in patients who exhibit any type of neurological damage, such as those caused by diabetes or chronic use of alcohol and eventually by aging.
In these cases, it is expected that the response to acupuncture is slower, and a larger number of applications is usually necessary to achieve the therapeutic goal.
Given this, one can conclude that the action of acupuncture depends on the peripheral nerve network. If it is damaged, the effectiveness of acupuncture will also be affected. The points used in the practice of acupuncture are numerous and, currently, if we consider the classic points and the extras, they can reach up to 2000 points.
