Romberg and Cerebellar Function
Romberg's test is not a test of cerebellar function, as it is commonly misconstrued. Patients with cerebellar ataxia will, generally, be unable to balance even with the eyes open; therefore, the test cannot proceed beyond the first step and no patient with cerebellar ataxia can correctly be described as Romberg's positive. Rather, Romberg's test is a test of the proprioception receptors and pathways function. A positive Romberg's test has been shown to be 90% sensitive for lumbar spinal stenosis.
