What test assesses the proprioceptors involved with posture?

Romberg’s test

Romberg’s test is a commonly used test to evaluate the integrity of dorsal columns of the spinal cord during neurological examination. The test can be elicited in many conditions affecting proprioception. It can be performed with no equipment at all which makes it very suitable for large scale deployment. This test is commonly used by police officers to detect imbalance due to alcohol intoxication.
