For static balance assessment, which tests are commonly used?

• A. TUG and Dynamic Gait Index
• B. Romberg and Sharpened Romberg
• C. Head impulse test and caloric testing
• D. Visual acuity test

Answer: (B)

Static balance assessment focuses on how well a person can hold still and maintain posture when visual input is limited, relying on the integration of proprioceptive and vestibular signals. The best match is Romberg and Sharpened Romberg because these tests specifically probe quiet standing and sensory dependency.

Romberg involves standing with feet together and arms at the sides, first with eyes open and then with eyes closed. Removing vision forces the body to rely more on proprioceptive and vestibular information to stay upright, so any instability that appears with eyes closed suggests sensory or vestibular contributions to balance.

Sharpened Romberg increases the challenge by having the person stand in a tandem stance (heel-to-toe) while again with eyes closed. This heightened difficulty makes it easier to reveal subtle deficits in balance control or sensory integration that might not show up in a simple Romberg test.

The other choices emphasize dynamic movement or different systems: head impulse test and caloric testing assess the vestibulo-ocular reflex during rapid head movements and caloric stimulation; these are dynamic and not about static posture. TUG and Dynamic Gait Index measure balance during movement and gait. Visual acuity tests gauge vision, not balance.
