Deep palpation. According to the information on the doctor's website, deep palpation is a method of overlapping one hand or two hands on the examined part, gradually applying pressure and touching deeply, so as to understand the situation of deep tissues and organs in the examined part. It is the best palpation method to determine the abdominal tenderness point, and can effectively diagnose the tension of the patient's abdominal wall, as well as whether there are superficial tenderness, lumps, resistance and so on.
