Posturography with head movements in the assessment of balance in chronic unilateral vestibular lesions

Abstract The aim of our study was to validate the method of head-shake static posturography (HS-posturography) in healthy individuals and to establish the value of this novel method in the diagnostics of patients with unilateral vestibular lesion (UV). The study included 202 participants divided int...
