Static posturography with proprioceptive sensory interfered

OBJECTIVE To evaluate the clinical value of static posturography with proprioceptivesensory perturbed. METHODS Beside vestibule-vision- proprioceptive sense (T1) and vestibule-proprioceptive sense (T2) of routine SPG, two new modes of static posturography (SPG) including vision-vestibule sense (T3) and single vestibule sense (T4) were established by putting sponge cushion on the static posturographic measurements platform for perturbing proprioceptive sensory. Four modes of SPG were performed on 170 healthy volunteers (control group) and 110 patients with peripheral vestibular disorders (experiment group) . The sensibitity and the clinical value of these four modes were assessed according to the normal value from control group. RESULTS General length and area of SPG were gradually increased from T1 to T4 in two groups, but these indexes were higher in experiment group than that in control group ( P0.05) . The positive rates of T3 and T4 in experiment group were 39.1 % and 89.1 % respectively, but only 21.8 % and 32.7 % in T1 and T2 (P0.05) . CONCLUSION This technique of SPG can eliminate the effect of visual and proprioceptive sense. The sensitivity and diagnostic value of SPG can be expanded and increased with the testing technique of proprioceptive and visual sensory perturbed.
