Which of the following results describes a positive Romberg test?

A. Loss of balance when feet are together and eyes are closed is correct because a positive Romberg test indicates deficiency in proprioception or vestibular function. During the test, the patient stands with feet together and eyes open, then closes their eyes. Normally, the patient can maintain posture due to sensory input from vision, proprioception, and vestibular systems. If the patient loses balance when vision is removed, it suggests dysfunction in the dorsal columns of the spinal cord or vestibular system, confirming a positive Romberg sign. B. Ability to maintain an upright posture with eyes closed is incorrect because this indicates a normal Romberg test, meaning the patient has intact proprioception and vestibular function. C. Falling while feet are together and eyes are open is incorrect because losing balance with eyes open suggests a more generalized balance or cerebellar problem, not specifically a positive Romberg test. Romberg evaluates sensory input when visual cues are removed, not balance in general. D. Patient report of feeling dizzy when eyes are closed is incorrect because subjective dizziness alone does not constitute a positive Romberg. The test relies on observed loss of balance, not just patient-reported sensations.
