Popis:	Background: The ICP pulse wave is getting more and more attention in research on traumatic brain injury and hydrocephalus. This study aims to investigate the measurability of the ICP pulse wave via lumbar space. Methods: Ten patients with confirmed communicating CSF-systems were included in the study. ICP was measured in the parenchyma above the frontal right ventricle, and CSF pressure (LP) was measured via the lumbar space. Pressure was manipulated by CSF infusion from baseline (mean = 19 mm Hg) to a maximum excess pressure (mean = 45 mm Hg). The amplitude of the ICP wave was analysed using Matlab and SPSS. Results: The mean difference between the intracranial and lumbar amplitude was 0.55 mm Hg (SD=1.48) [range: -2.3 to +3.6] (p
