How does cervical SMT affect vertebral artery or cerebral hemodynamics?
- RRS Education
In spite of a wealth of epidemiological evidence to the contrary, many clinicians and members of the general public still believe that neck manipulation increases the risk of vertebrobasilar artery (VBA) stroke. Prior hemodynamic studies have failed to demonstrate any changes in vertebral blood flow or blood velocity following cervical manipulation in healthy populations. However, the impact of cervical spinal manipulation on vertebral artery hemodynamics has not been assessed in patients with neck pain.
Therefore, these authors aimed to determine whether cervical spinal manipulation leads to meaningful changes in vertebral and cerebral hemodynamics, compared to neutral or end-range neck rotation postures in adults with chronic neck pain. They secondarily attempted to compare the functional connectivity of the default mode network (DMN) in different neck positions...What did they find? LOG IN OR SUBSCRIBE TO ACCESS THIS REVIEW!
