Meningeal irritation sign is a common sign in neurological physical examination, and its positivity is mainly seen in central nervous system infection, subarachnoid hemorrhage, meningeal cancer, and other diseases, which is easy to appear mainly when the meninges and nerve roots are involved. When the patient is lying down, the examiner stands on the right side of the patient, holds the patient’s occiput with the left hand, puts the right hand in front of the patient’s chest, and flexes the patient’s neck to feel whether there is any resistance and how to bend, and if there is cervical ankylosis, it will belong to one of the positive signs. The patient’s bilateral hip and knee joints are then observed for flexion, and if there is any, it is one of the positive signs of Briggs’ sign. Then the examiner lets the patient lie flat, holds the patient’s knee with the left hand, holds the patient’s ankle with the right hand, and slowly lifts the patient’s leg upward to keep the knee at 90 degrees. When the calf is lifted upward more than 135 degrees, and obvious pain or resistance occurs, it means that Kirschner’s sign is positive. Cervical ankylosis together with Kirschner’s sign and Bucher’s sign constitute the complete meningeal irritation sign.
