The Spirit of Function

Earth, fire, and the wind…mind, body, and spirit…muscles, nerves, and joints. Some of the most powerful forces we experience in life can’t be seen with the naked eye. The wind, our spirit, and our nerves are all intangible, but the power that they have is undeniable. In this issue of the Functional Video Digest Series, Gary Gray takes a unique look at the invisible power of proprioceptors, the very spirit of function. He discusses the different proprioceptors, where they are located, and what their function is. Through the DVD, a functional understanding of proprioceptors is provided, bettering evaluative, rehabilitative, and training techniques. These unseen forces act as powerful drivers in our life, and understanding them will enhance our knowledge of human function.
