Hyperactivity and Proprioception

Skeletal muscles have two kinds of fibers: slow and fast. Fast fibers are organized by segments and slow fibers are organized globally, designing a system. This system is part of the proprioceptive system and it works globally connected to it. In the case of a proprioceptive system dysfunction, slow fibers are blocked and don't work properly. Patients will feel tired and the brain will try to solve the problem by using the only fibers that are working properly: fast fibers. In order to do so, patients need to enter in hyperactivity. If we correct the proprioceptive dysfunction though, patients don´t need to enter in hyperactivity, they return to using the slow fibers and their activity becomes normal.
