Involuntary Muscular Contractions. — In this condition, which occasionally accompanies certain forms of paralysis, the extremities, especially fingers and toes, undergo uncontrollable spasms. These spasms may consist in the members being firmly separated or flexed. They may occur during sleep and may be increased by fright or other emotions. Treatment is in accordance with that for paralysis.[1][1] There is no standard treatment for the symptom.
