Quadriplegia is a clinical sign consisting of the complete loss of motor power in all four extremities. It is most often due to pathology of the central or peripheral nervous system or muscle disease; very seldom it is psychogenic. High spinal cord lesions, multiple peripheral nerve involvement as in the Guillain-Barré syndrome, or widespread muscle dysfunction as in hypokalemic periodic paralysis can lead to quadriplegia. Treatment depends on the etiology.
