The meningeal stimulation sign includes three parts: cervical tonicity, Kirschner’s sign and Brønsted’s sign. 1. Cervical tonicity is one of the more important objective signs of meningeal stimulation, which is manifested by significant resistance when flexing the patient’s neck, and the lateral bending of the head is also restricted. 2. Kirschner’s sign, also known as hip flexion and knee extension test, is when the patient is lying on his back, making his lower limbs flexed and the knee joint at a right angle, then holding the knee joint with one hand and the ankle with the other hand, passively straightening the flexed lower leg. When the knee joint is extended more than 135° and there is pain or if you feel obvious resistance, it is positive for Kirsch’s sign. 3.Bucher’s sign is to observe bilateral hip and bilateral knee when lying down and flexing its neck, if there is joint flexion, if there is flexion, it is positive. This test, is mostly used to diagnose diseases with meningeal injury, such as various types of meningeal inflammation and subarachnoid hemorrhage.
