The Connection to Vertebral Basilar Insufficiency (VBI):
Vertebral basilar insufficiency (VBI) refers to a decrease in blood flow through the vertebral and/or basilar arteries, which supply blood to the brainstem and the posterior part of the brain. In some cases, cervicogenic headaches may be associated with VBI due to compromised blood flow in these arteries. It is crucial to identify and address VBI-related concerns to ensure safe and effective physiotherapy interventions.
