Abnormal Finding

• Smoothness
  • Ataxia: Movements are clumsy, and vary in their speed and direction (Cerebellar disease).
  • Kinetic Tremor: A tremor appears toward the end of movement ( Cerebellar disease).
• Accuracy
  • Dysmetria (or past-pointing): Finger initially misses but finally reaches the target ( Cerebellar disease).
    • If inaccurate only with eyes closed, consider impaired position sense rather than cerebellum as the cause.
    • Limbs with ataxin or dysmetria reflect an ipsilateral cerebellar (or tract) lesion.
