Professor Li Zhidao found that when practicing acupuncture on patients with weak body constitution, non-urgent pain due to long-term disease course, or poor acupuncture tolerance, it is often inappropriate to produce too strong stimulation effect. Instead, good therapeutic effect can be obtained by using the “weak acupuncture sensation method”. The application essentials of “weak needle sensation method” mainly include needling method, needle retention method, and needle withdraw method, etc. By adhering to the idea of “acupoints cannot be separated from meridians”, this method should avoid needling tissues around the acupoints that are easy to cause strong acupuncture sensation. During the needle retention period, no manipulation of needles is allowed, or only needle manipulation with small amplitude, low frequency and short time is allowed. When withdrawing needles, gentle and soft needle withdrawal is adopted.The acupuncture therapy abandons the previous clinical thinking pattern, that is, “the stronger the acupuncture sensation is, the better the curative effect will be”, and provides a new idea of clinical treatment for patients with poor acupuncture tolerance by controlling acupuncture sensation.
