Which test involves walking heel-to-toe to assess cerebellar function?

• A. Walk across the room
• B. Walk heel-to-toe
• C. Walk on the toes then the heels
• D. Shallow knee bend

Answer: (B)

Tandem gait—walking heel-to-toe—tests cerebellar coordination and balance. Placing each foot heel in front of the other narrows the base of support and requires precise, timed control of movements. The cerebellum coordinates these rapid, accurate foot placements and smooths the gait, so abnormal tandem walking shows up as unsteadiness, wide-based steps, or noticeable missteps, indicating cerebellar dysfunction. Other gait maneuvers assess related but different aspects: simply walking across the room checks overall gait and strength; walking on the toes and then the heels tests distal leg strength and the ability to shift weight with different foot postures; a shallow knee bend evaluates knee/hip strength and range of motion. The heel-to-toe test specifically challenges the fine coordination and balance that the cerebellum governs, making it the best choice for assessing cerebellar function.
