[Exploration on two methods of waiting for in needle insertion and withdrawal of acupuncture reinforcing and reducing technique recorded in ()].

The reinforcing and reducing technique based on the speed of needle insertion and withdrawal is the important acupuncture technique recorded in (). Regarding the speed of needle insertion and withdrawal, the timing of needle insertion and withdrawal is one of the key factors to judge the therapeutic effects. In the paper, the origin was studied on the two methods of waiting for recorded in (), e.g. "waiting for respiratory " and "waiting for beneath needle"; and its application progression and clinical significance were explained. Of them, the "waiting for beneath needle" is mostly used to decide the timing of needle withdrawal and closely related to the therapeutic effects of reinforcing and reducing technique; and its application is fully developed in later generations. In (), it stresses the needle insertion after waiting for with the assistant hand, lifting and thrusting manipulation is followed after arrival of beneath needle. This technique brings the impacts on the reinforcing and reducing technique of acupuncture in later generations.
