Insufficient blood supply to the brain is also common in neurosurgical practice and is divided into insufficient blood supply to the internal carotid system and insufficient blood supply to the basilar system. Insufficient blood supply to the internal carotid artery system, doing some movements is not helpful for cerebral ischemia. The key is that patients with insufficient blood supply to the vertebrobasilar artery can do health care actions to improve the performance of insufficient blood supply to the brain. Most of the patients are caused by cervical spondylosis. For patients with cervical disc herniation, patients can practice more swallow flying, that is, lying prone on the bed with the head and neck elevated and the limbs stretched backward to land on the abdomen, or they can practice more head raising including looking up at the sky and looking back at the moon.
