Paralysis ayitans is a form of paralysis which is accompanied by tremor and rigidity of muscles; the tremor is a more prominent symptom than the paralysis, the affected muscles manifesting involuntary rhythmical contractions, and the disease is thus sometimes known as shaking palsy. Persons advanced in life are usually affected, and the disease is of an eminently chronic character.
