Which test is used to assess vestibular function in TBI evaluation?

• A. Vestibular function tests
• B. Visual acuity tests
• C. MMT
• D. ROM

Answer: (A)

The key idea is directly assessing how the vestibular system—your inner ear balance organs and the brain areas that integrate balance with vision and motion—functions after a brain injury. Vestibular function tests are designed to probe that system, measuring how well the semicircular canals and otolith organs respond and how the vestibulo-ocular reflex coordinates eye movements with head movements. This helps identify dizziness, imbalance, or vertigo stemming from vestibular disruption. Examples include caloric testing, rotary chair testing, video head impulse testing, vestibular-evoked myogenic potentials, and dynamic posturography. In contrast, visual acuity tests examine vision clarity, MMT checks muscle strength, and ROM assesses joint movement—none directly evaluate vestibular function.
