A positive Romberg test indicates which of the following?

• A. Tests auditory function to determine balance.
• B. Tests sensory contributions to balance by having eyes closed; a positive Romberg indicates proprioceptive or vestibular impairment.
• C. Assesses visual acuity.
• D. Measures reaction time to auditory stimuli.

Answer: (B)

Balance relies on three main inputs: vision, proprioception (body position from joints and muscles), and the vestibular system in the inner ear. The Romberg test specifically removes visual input to see how well proprioceptive and vestibular signals can keep you upright.

When someone stands with feet together and eyes closed, vision can no longer help stabilize them. If their balance deteriorates—swaying or inability to maintain posture—that positive result points to problems with proprioceptive input or vestibular function. In other words, the test highlights how well the body can rely on somatosensory and inner-ear information when vision isn’t available.

This isn’t a measure of auditory function, visual acuity, or reaction time to sounds, so those aspects don’t explain a positive Romberg.
