Familial paroxysmal dystonia induced by exercise.
A mother and daughter are described with paroxysmal dystonia induced by exercise. As has been reported in one previous family, the attacks were provoked in the lower limbs by prolonged exertion but not by sudden movements. It was also found that involuntary movements could be induced focally in any limb either by local exercise or by sensory stimulation restricted to that limb.
