title: Phantom sensations in a patient with cervical nerve root avulsion.
abstract: This case study reports detailed phantom sensations in a 35-yr.-old man who had his C5 and C6 cervical nerve roots avulsed from the cord during a motorcycle accident at the age of 22 years. The subject, who was left with a paralyzed right deltoid muscle, anesthetic sensation along the upper lateral portion of the right arm, and absent right biceps reflex, became aware of phantom right arm and hand sensations a few months after the original injury. This finding--which has important implications for understanding the process involved in bodily perception as well as the development of these perceptions--provides evidence of a distributed neural representation of the body that has both genetic and experiential determinants. The implications of these findings are discussed with reference to recent concepts of phantom limb experiences and related phenomena.
