Crainocervical Arteries: A Case Study

As long as treatment is important, also precaution and safety before and during sessions are worthy too. One big issue that takes controversy opinions around is the effectiveness of sustained end-range rotation on crainocervical arteries and if it is affecting on the amount of blood to brain. In this abstract can defined the sustained end-range rotation as a pre-manipulative screening test tool that utilise to examine insufficiency of brain blood supply on crainocervical arteries as vertebrobasilar arteries and internal carotid arteries through three different neck positions. According to (Thomas LC, et al. 2015) explains a relationship between manipulation of neck especially rotation and decrease blood flow in VAs and ICAs. However, several
2015). Authors mentions couples of arteries issues that it might be considered as neck manipulative risks such as VA hypoplasia, prior VA injury and previous VBI symptoms. Useful of these information clinically, therapist before starting a treatment session have to get a clear history first then carefully explore via VBI screening test, as sustained end-range rotation, signs and symptoms of VBI. There are some recommendations resulted from limitations that had faced studies. Firstly, doing the screening test while patient is setting rather than supine lying positions. Because the blood flow will be more in supine position. Secondly, better to do the rotation passively than actively movement due to receive more ROM and blood changes. Finally, closing patient’s eyes during examination to avoid substitutional way that could be lower the validity of findings. That occur by stimulate the visual cortex and that will increase the blood in posterior cerebral
