95. A computerized static posturography protocol in the assessment of balance impairment of Multiple Sclerosis patients

Balance impairment is common in Multiple Sclerosis (MS) patients. We administered the modified Clinical Test of Sensory Interaction on Balance (mCTSIB) to 73 MS patients and 57 healthy controls, with the aim to collect normative data and compare sensitivity of mCTSIB and clinical examination in detecting balance impairment. Subjects were asked to stand quietly upright for 10 s with eyes opened and then eyes closed (EC) (3 times per condition) on a firm surface on a fixed dual forceplate. The centre of gravity (COG) sway was expressed as velocity (deg/s) and path length (mm); MS patients were examined with the Romberg Test (RT), scored according to Neurostatus. mCTSIB-EC clearly allowed to differentiate patients with positive RT (0.38 deg/s, CI 0.32–0.43) from those with negative RT (0.19 deg/s, 95% CI 0.17–0.21, p
