I went to a seminar about Auto Collision Related Spine Injuries 2012 II by Dr. Dan Dock, DC on Thursday, March 8th, 2012. Here I will share some of the information that I learned from the seminar. Cranial nerve I to XII function and auto collision injuries were the topic. There were lots of information about cranial nerve evaluation and it's clinical relations. It really reminds me the good old days in the neuroanatomy and neurology class in school. The seminar was very in depth and felt like attending a neuro diplomat class.
Dr. Dock also talked about Sidney Crosby's concussion like symptoms. Concussion like symptoms such as his dizziness and blur vision is a result of neck muscle strain/tightness.1, 2 Post trauma vertigo may be due to vasomotor instability.2 But, may be due to vestibulospinal system or chronic neck spinal muscle tightness. Cervical vertigo can be a result of dizziness from proprioception, vertebral artery irritation or sympathetic irritation. Chiropractic adjustment can help condition like this. Dr. Dock says that we are already helping people with similar condition in our daily practice even though you are not treating Sidney Crosby. You might have heard patients say that they can see better after cervical adjustment. The neurological pathway after cervical adjustment is that it stimulate the proprioceptor in the spinal cord. The information goes to the cerebellum via medial longitudinal fasciculus tract. It then goes to to CN III, IV, and VI that helps with vision.
There are other diseases causing blur vision and dizziness such as ALS, MS, stroke and aneurysm. These are contra-indication for chiropractic treatment. In the seminar he went over signs and symptoms of many disease related to cranial nerves. It was quite a morning re-learning neurology. I had fun!
