Scenario A John is 50 years old and has had a stroke in which he sustained damage to the cerebellum. His upper extremities and lower extremities have some altered tone in the muscles, but he is able to move against gravity and withstand resistance. However, his main impairment is Ataxia during gait, loss of balance, and uncoordinated movements while walking, especially side to side. The physiotherapist is requesting you assist John with ambulation on floor level.
