Akinetic
Without movement (or without much movement). A term used in neurology to denote the absence (or poverty) of movement. The word "akinetic" comes from the prefix "a-" meaning "without" + the Greek word "kinesis" meaning motion = without motion. For example, a person in coma is akinetic. For another example, akinetic mutism is a condition in which a person is both mute and akinetic. A textbook on clinical neurology observes that a person with akinetic mutism has "sleep-waking cycles but, when apparently awake, with eyes open, lies mute. immobile and unresponsive."
