A comparison of head movements tests in force plate and accelerometer based posturography in patients with balance problems due to vestibular dysfunction

Abstract This study compares HS posturography on inertial sensors (MediPost) with force platform posturography in patients with unilateral vestibular dysfunction. The study group included 38 patients (age 50.6; SD 11.6) with unilateral vestibular weakness (UV) and 65 healthy volunteers (48.7; SD 11....
