What does a positive Romberg test indicate in a patient?

A positive Romberg test is primarily indicative of issues related to proprioception and balance, which can often point to dysfunction in the cerebellum or related pathways. The test assesses a person's ability to maintain balance while standing with feet together and eyes closed. When the patient sways or falls during this test, it suggests that they may have difficulties integrating sensory information necessary for maintaining posture, particularly due to issues with cerebellar function.

While the test could also suggest areas influenced by vestibular dysfunction or sensory input from the visual and proprioceptive systems, the classic interpretation ties a positive Romberg test closely to cerebellar dysfunction, as the cerebellum is crucial for coordination and balance. Therefore, when interpreting the results of this test, the prominence of cerebellar function in maintaining balance is why a positive result is most closely associated with cerebellar dysfunction.
