Psychogenic Gait Disorder
A 51-year-old man exhibiting gait impairment, right hand action tremor, and left leg resting tremor. Examination showed brief motor arrests during gait initiation and turning, steppage of the left foot, and fixed posture of both hands. While sitting, fixed hand posturing disappeared during distraction maneuvers. Leg tremor was present when the foot was resting on the anterior sole but not when resting on the heel or when unsupported. Deliberate slowness in both upper limbs was demonstrated during finger-to-nose movements and repetitive arm movements, although spontaneous movements were normal, as was writing.
