Good proprioception (awareness of limb position in space and time) is essential for all tasks, whether complex or simple. Picking up the remote to watch TV or doing a single leg squat on a BOSU all require varying degrees of proprioception or neuromuscular control. Essentially proprioception is this relationship between the neurological system and the muscular system and any injuries that occur e.g. trauma can cause a disruption between the the communication of these two systems. Sensory (afferent) feedback is interupted (like your Mum asking you to do the washing up when you're on the phone) and this has reprecussions on motor control (you drop the phone!)
