Movement of cerebrospinal fluid within the craniospinal space when sitting up and lying down.
Postural changes in the lumbar cerebrospinal fluid pressure were recorded in patients with and without a cervical obstruction of the subarachnoid space. In patients with a free communication there was a rapid caudad movement of CSF on sitting up and a craniad movement on lying down. The relation of these changes to cerebral blood volume and to symptoms are discussed.
