The possibility of MAB method for controlling spasticity.

ABSTRACT

Muscle afferent block method (MAB) for controlling spasticity was studied in six paralyed patients who had severe spasticity of bilateral adductor muscles by injecting 0.5 percent xylocaine + 99.5 percent ethanol (10 1 cc) and 5 percent phenol directly into the right and left adductor muscles respectively without making any attempt to locate the nerve sites. The study evaluated the treatment by passive abduction and spastic scale. The result showed that spasticity could be decreased both sides. Five percent phenol produced better result and longer duration of 3-4 days compared with 1-2 days when 0.5 percent xylocaine + 99.5 percent ethanol was used.
