Vestibular Assessment

Information About Balance Problems. Normal balance requires the integration of three sensory systems: - visual- vestibular (found in the inner ear), and - somatosensory (sensations from the skin, muscles, tendons and joints) in addition to muscle strength. When these systems are not functioning well, individuals may experience episodes of spinning, light-headedness, trouble focusing their eyes and/or poor balance or falls..
