What is tested during Romberg's test?

Romberg's test is a clinical assessment used primarily to evaluate an individual's balance and proprioception. During the test, the patient is asked to stand with their feet together and arms at their sides or sometimes extended out to the side. The clinician observes the individual's ability to maintain stability in this position, both with their eyes open and then with their eyes closed.

The purpose of Romberg's test is to assess the integrity of the neurological pathways involved in balance, particularly the vestibular, visual, and proprioceptive systems. When the eyes are closed, the individual relies solely on proprioceptive information and vestibular input to maintain balance. If a person sways or falls during this test, it can indicate issues with these systems.

In the context provided, the correct answer focuses on evaluating balance when the feet are together and arms are positioned, which aligns perfectly with the purpose and execution of Romberg's test.
