The specific practices of neurological examination are as follows: 1. Physical examination: the doctor does the examination directly on the patient. When the patient is admitted to the hospital or outpatient clinic, the doctor will do a simple physical examination with the help of simple instruments, using a percussion hammer, tongue depressor, cotton swabs, etc., including the examination of the patient’s strength, sensation, reflexes, and cranial nerve aspects. For example, the doctor will ask the patient to hold the hand tightly or straighten it to test the strength; take the percussion hammer to snap the tendon to see the strength of the reflex; use the blunt end of the needle to stimulate the local area to see the sensation; also use the cotton swab to do the reflex of the pathological needle, etc.; 2. Other related examinations: that is, further examination with the help of instruments, such as CT, MRI, etc., to see the structure and activity inside the brain, and electromyography to see the activity of nerve conduction, which is a relatively more complex examination.
