摘要
Background Small acoustic neuromas seldom result in typical vestibular symptoms, despite the tumor arising from the vestibular nerve. In this study, we have shown that abnormal gait in eleven patients with small acoustic neuroma could be detected in gait analysis by the use of tactile sensor. Patients displayed no oculomotor abnormality and had tumors less than 10 mm from the porus acoustics. Methods Gait related parameters including the coefficients of variations （CV） of stance, swing, double support, area ratio of trajectories of center of force （TCOF）, in addition to the foot pressure difference between both feet, were used for assessment of gait.
