It's a feeling in your bones. It does exist and you do use it - all the time. It's a feedback sense, all about reaction. As you move Proprioception tells your brain how things are progressing and your brain responds with subtly different movement orders. For most people it's all so automatic that a genuine proprio problem tends to flummox us - you might know how to crack an egg, but can you safely open a sachet? Our Proprioception, Vestibular and Tactile senses together are targeted during Sensory integration therapy.
