Cervical Spine Studying

With the amount of time that has been focused into developing Strata Biomechanics Inc, study time has been less than normal. Fortunately today I had the opportunity to review some cervical spine mechanics and review whats muscles influences what joints directly and indirectly. Here is a brief review of what I touched on today.

For me to use MAT to stimulate muscles around a joint, I need to know what the bones are shaped like and the mechanics associated. The shape of the bones contact surfaces can influence what kind of motions can happen directly and indirectly, this is called artho-kinetimatic interdependence. Its motions become dependent upon the shape of the articular processes and the vertebral body and at what point of motion the spine is sitting. The spine has 33 bones, 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, 4 coccyx and place perfectly onto is the skull. Each of these groups of bones have a curve that general has a kyphotic or lordotic curve and tend to alternate from one group of bones to another.

The cervical spine has a unique set of structures that are intimately related to one and other. The joints that were studied specifically today were the Atlanto-Occipital (O/A- Skull and C1) joint and the Atlanto-Axial joint (A/A – C1 and C2). My goal was to become more comfortable with the accessing motion at these joints.

The mechanics of the O/A joint are similar to the thoracic spine, in that they both have type 1 spinal mechanics ( when rotation occurs to one side, side bend simultaneously occurs to the opposite side ). This means that when I am checking the skulls ability to side bend, there should be a bit ofrotation to the opposite side. This in it self helped me with a lot of insight as far as checking O/A motion.

The mechanics of the A/A joint resemble that of the lower cervical spine and the lumbar spine, type 2 spinal mechanics ( when rotation occurs to one side, side bends simultaneously occurs to the same side ). This joints allows approximately 50-65% of the rotation that is available in the entire cervical spine. With this statistic alone, I’m sure you can imagine how much dysfunction could occur if the A/A joint was working as much as it should be. A big part of today’s study session was to becoming more comfortable with passively accessing the A/A motion.

Finally I created lists that were associated with the direct and indirect influences of muscles over these joints. There are only a few muscles that directly connect to the O/A and A/A joint but I felt it was important to become comfortable with these first. The last piece of today’s puzzle was seeing what muscles indirectly can influence motion at these joints. I came up with some very neat discoveries that I would be happy to share with anyone who would like to visit my office and study with me!

Thanks for reading! I try to study as often as I can and digest a bit of new information every time. If you are ever in the Newmarket area and are interested in reviewing anything related to the human body, please let me know! Stratabiox@gmail.com
