A physical examination is when a doctor performs a relevant physical examination of a patient. The diagnosis of certain diseases is considered by finding positive signs during the visual, tactile, percussive, and auditory examinations. A TCM doctor may do this by looking, smelling, questioning, and cutting. The main feature of the examination is that the doctor performs a physical examination of the patient’s vital signs, general condition, skin and mucous membranes, lymph nodes, head, neck, heart, lungs, abdomen, anus and genitals, spine and limbs, and nervous system, without the use of laboratory and imaging equipment, and detects positive signs during visual, tactile, percussive, and auditory examinations. The doctor interviews the patient and conducts a general examination of the patient’s organs with his/her hands and a stethoscope or percussion hammer. Alternatively, the doctor may examine the surface of the patient’s body, checking for pressure and pain on a localized area or part of the body surface to determine whether the organ in question is suffering from a disease.
