title: Bovine spastic paralysis: results of surgical desafferentation of the gastrocnemius muscle by means of spinal dorsal root resection.
abstract: A dorsal laminectomy of L-4, L-5, and L-6, followed by resection of the dorsal (afferent) roots of the gastrocnemius muscle (desafferentation) was performed on 3 calves which had spastic paralysis. All signs of the condition disappeared after desafferentation. This suggests an overactive stretch reflex to be the cause of the spastic paralysis.
