Head Position and Posturography: A Novel Biomarker to Identify Concussion Sufferers

Carrick, Pagnacco, Hunfalvay, Azzolino, Oggero

Brain Sciences

Head and neck position induced by statically maintained head turns is associated with lower stability scores than the standardized head neutral position of the mCTSIB in Post-Concussion Syndrome (PCS) subjects but not in healthy controls. Head positions of the neutral plane provide biomarkers that differentiate subjects suffering from PCS from healthy normal subjects.
