(2) As a characteristic of water acupuncture, clinical treatment often selects positive reaction points in combination with palpation of meridians and acupoints, that is, pressing, touching and sliding the patient's body surface evenly with thumb or forefinger to check whether there are tender, cord-like or nodular positive reactants, as well as depressions, bulges and discoloration of the skin. The location of palpation is generally the back Shu points on the back and waist, and the limbs are touched along the meridian route, especially the special points such as the original point, the Yi point and the combined point and some experience points. Those who have positive reactions such as tenderness are often injected into the reaction point, and those who have no obvious reaction can also be treated at Shu, Mu and Bian points.
