A patient undergoes the Romberg test, and he cannot maintain balance with eyes open and eyes closed. What is the Romberg test interpretation?

Correct answer is D). A "negative" Romberg test, in the context described, implies that the patient cannot maintain balance with both eyes open and eyes closed. This result is indicative of cerebellar ataxia, where there is a fundamental problem with balance and coordination. Cerebellar ataxia can significantly affect a patient's ability to maintain a stable posture and gait.
