Which statement best describes the Romberg test?

• A. It assesses proprioception and balance with eyes closed
• B. It assesses cerebellar function with rapid movements
• C. It assesses motor strength of the legs
• D. It assesses visual acuity

Answer: (A)

Romberg testing focuses on proprioceptive input and balance when visual input is removed. Have the patient stand with feet together and arms at the sides, first with eyes open and then with eyes closed. If balance is preserved with eyes open but becomes unstable or they sway markedly with eyes closed, this points to a proprioceptive deficit—sensory ataxia from dorsal column or peripheral neuropathy—because the person can’t rely on the sense of position without visual guidance. In contrast, cerebellar ataxia typically shows unsteadiness even with eyes open. The test is not about motor strength or visual acuity, and rapid movement tests target cerebellar function rather than the proprioceptive balance assessed by the Romberg test.
