Which sign involves inability to judge distance or range of movement?

Explanation:
Dysmetria is the inability to gauge distance or range of movement, signaling cerebellar dysfunction. The cerebellum helps fine-tune movements by comparing intended action with actual movement; when this calibration is off, you overshoot or undershoot targets, especially in tasks like finger-to-nose. This sign is distinct from a broad-based gait, which points to ataxia affecting balance, decreased muscle tone (hypotonia), which lowers overall muscle tension, or tremor, which is an involuntary oscillation. So the described sign specifically reflects dysmetria—the cerebellum’s impaired judgment of movement distance.
