Definition of Akinetic


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."
