Results

• Eumetry - target is hit.
• Hypermetry - movement goes beyond the goal
• Intention tremor - increasing tremors as you approach your goal
• Hypometry - goal is not (completely) achieved

Hypermetry and intention tremors are indicative of a functional disorder of the cerebellum , while hypometry is usually the result of paralysis of the respective arm.
