These last two weeks have been building up to Chain Reaction Biomechanics of the Lumbar and Thoracic spine. The Lumbar spine is the cross roads of the body. It reacts to what is happening in other joints of the body. The two key joints to assess with Lumbar spine pain are the hips and Thoracic spine. If the hips and Thoracic spine have good motion then the feet and the Cervical spine might be influencing their motion respectively.
When considering Chain Reaction Biomechanics of the Lumbar and Thoracic spine, look at the top down and bottom up drivers. When I am tring to influence these spinal areas, I can choose a multitutde of ways to create top down and bottom up triplane driver motion.
In the Thoracic spine we can look at in sync and out of sync motion. In sync motion means the pelvis and the shoulder move in the same direction e.g. a tennis forehand, a golf swing, a baseball batter. Out of sync means the pelvis and shoulders moving in opposite directions. When I am testing and treating the Tx, I want to choose the appropriate insyn or out of sync motion, based on the TZ I am assessing. If the TZ is insync then I can use foot and hand drivers to replicate this motion.
The Quadriceps is a a group of muscles designed to lengthen with triplane decelerating motion at the knee. This requires the physioological motion of flexion, internal rotation and abduction at the knee. It does little to help with extension of the knee in gait. This is done mainly by the soleus, Tib. Post. and P. Longus slowing down the Tibia and the mass and momentum of the body coming over the tibia to extend the knee. Remember the factors creating the forward momentum will be the Glutes and hamstrings and the swing of the opposite leg. In fact remember all the muscles work together and we cannot fully seperate their function.
We also looked at tweaking using Triagulation variables. This means changing the Angle, Verticality or Horizontal components of triangulation together or seperately. I noticed I could get different responses in the body when I changed these components in different orders e.g. A,V,H or V,H,A or H,V,A This is a useful tool to find what is most successful for a client and where to start my rehabilitation.\
We are now building to GG2. I am looking forward putting all this information into use and learning more from the Gray Institute
