title: Reduced spinal reflexes following intrathecal baclofen in the rabbit.
abstract: Intrathecal baclofen is effective in reducing polysynaptic spinal reflexes in awake rabbits. A single lumbar infusion of 2.5-5.0 ng drug caused a significant reduction in the crossed extensor response to electrical stimulation of the plantar surface of the hindlimb. This inhibition lasted 5 h or more. At doses of 3 micrograms or less, the forelimbs were unaffected.
