Non-functional movement is similar to finding your way in the dark. Functional movement is similar to finding your way in the light. The difference can be summed up in one word: electricity. Electricity (think of a light switch being “on”) sure makes moving easier because we can see what is around us and move accordingly. We at Gray institute® consider Proprioceptors to be the electricity of the body. The more these are turned “on,” the safer our patients and clients are. Furthermore, the more Proprioceptors are turned “on” authentic to the intended task (or function), the safer and better prepared our patients and clients are.
