Topple Testing Platform

Head Injury Panel:

Topple’s Head Injury Panel is a diagnostic screening tool utilized to identify the potential underlying causes of a mTBI, also known as a concussion. We utilize several diagnostic tests, including Ocular Motility testing (the only research backed objective test measure), to identify functional impairment to a patient's central nervous system.

Vestibular Equilibrium Panel:

Our Vestibular Equilibrium Panel evaluates the auditory and vestibular systems, as well as associated central nervous system and balance components to provide a comprehensive understanding of the status of the dizzy/imbalanced patient. Our testing assists in confirming central and/or peripheral involvement that can be due to head injury, TBI, concussion or cervical trauma.
