The compression of the fourth ventricle (CV-4) is one of the more well known procedures in the cranial manipulation curriculum and practice. Cranial manipulation has received criticism because of the subtle, difficult to learn techniques, controversy over whether or not cranial bone structures move, and what if any clinical effects have been shown. The aim of this study was to measure the effects of CV-4 in 10 healthy subjects through quantitative electroencephalography (qEEG), specifically in alpha band. Participants were randomly distributed in control, sham-CV4 and CV4 conditions using a cross-over design. qEEG activity was recorded for each of the 10 subjects in each of the 3 conditions. There was a significant increase in the alpha absolute power between pre and post in the CV-4 condition. There appears to be potential for understanding the effect of the CV-4 if these finding are replicated in further clinical trials.
第四脑室压迫术（CV - 4）是颅骨整复课程与实践中较为知名的操作之一。颅骨整复因技术细微、难学，颅骨结构是否移动存在争议，以及是否显示出临床效果等问题而受到批评。本研究的目的是通过定量脑电图（qEEG），特别是在阿尔法波段，测量10名健康受试者中CV - 4的效果。采用交叉设计将参与者随机分配到对照、假CV4和CV4组。在三种条件下，对10名受试者中的每一位都记录了qEEG活动。在CV - 4组中，阿尔法绝对功率在术前和术后有显著增加。如果这些发现能在进一步的临床试验中得到重复，那么似乎有可能理解CV - 4的效果。
