Proprioception

Everything starts with our brain and how much information it has to work with. Our senses give us information about our external and internal environment. Riders rely heavily on vision, inner ear and joint receptors to tell us where we are in space and time. If one of these senses/receptors are dysfunctional it can have an impact on our position. Something as simple as how well your eyes move left and right can affect the weight into each stirrup.
