Final answer:
Gait disturbance with involuntary acceleration can be a symptom of ataxia, a movement disorder of the cerebellum that causes a loss of coordination in voluntary movements.
Step-by-step explanation:
Gait disturbance with involuntary acceleration can be a symptom of ataxia, a movement disorder of the cerebellum. Ataxia is characterized by a loss of coordination in voluntary movements and can also cause balance problems. When gait disturbance is observed, it is typically attributed to damage in the cerebellum. Sensory and vestibular ataxia can also present with gait and balance issues.
