Two patients with subarachnoid hemorrhage recovered consciousness after intrathecal baclofen administration using an implanted intrathecal baclofen pump delivering 50 microg per day using a simple infusion mode. Intrathecal baclofen resulted in significant reduction of spasticity 3 months after the implantation. Case 1 was reduced to a completely bedridden state with spasticity and could slightly move her fingers following commands. However, the patient could eat food and wash her face with minimal assistance at 3 months after the implantation, and could stand up in the parallel bars with assistance and speak several words at 8 months. Case 2 was in a completely bedridden state at 10 months after onset and could neither drink water nor follow instructions. However, the patient became oriented and could eat by herself within 3 to 4 weeks of implantation. She could walk with a cane and use the stairs with minimal assistance at 2 and 3 months after implantation. The patient could speak fluently within 6 months of implantation. Flatulence and dysuria happened during the screening test, but these symptoms were not repeated after implantation of a pump-catheter-system and continuous intrathecal baclofen infusion. Continuous intrathecal baclofen infusion caused both improvement in muscle tone and spasms and consciousness recovery from the vegetative state. This therapy is a strong candidate treatment for patients with spasticity and consciousness disturbance.

Spasticity is a condition that can include increased muscle tone, clonus, spasms, and hyperreflexia. In this study, we report the effect of manually stimulating the dorsal lumbosacral skin on spontaneous locomotor-like activity and on a variety of reflex responses in 5 decerebrate chronic spinal cats treated with clonidine. Cats were spinalized 1 month before the terminal experiment. Stretch reflexes were evoked by stretching the left triceps surae muscles. Crossed reflexes were elicited by electrically stimulating the right tibial or superficial peroneal nerves. Wind-up of reflex responses was evoked by electrically stimulating the left tibial or superficial peroneal nerves. We found that pinching the skin of the back abolished spontaneous locomotor-like activity. We also found that back pinch abolished the rhythmic activity observed during reflex testing without eliminating the reflex responses. Some of the rhythmic episodes of activity observed during reflex testing were consistent with clonus with an oscillation frequency greater than 3 Hz. Pinching the skin of the back effectively abolished rhythmic activity occurring spontaneously or evoked during reflex testing, irrespective of oscillation frequency. The results are consistent with the hypothesis that locomotion and clonus are produced by common central pattern-generators. Stimulating the skin of the back could prove helpful in managing undesired rhythmic activity in spinal cord-injured humans.
