Study on the balance function in patients with peripheral vestibular disorders

OBJECTIVE To evaluate the balance function of patients with peripheral vestibular disorders,to analyze the characteristics of vision and proprioception in postural control.and provide baseline data for balance rehabilitation therapy.METHODS All subjects were divided into two groups.47 normal individuals,21 male,26 female,the average age was(36.17±13.27)years old;45 patients with peripheral vestibular disorders,20 male,25 female,the average age was(47.89±13.04)years old.All were assessed by computerized posturography under six upright stance conditions:including standing on the firm surface and foam with eyes open and closed.RESULTS ①The three sensory scores and equilibrium scores on anteroposterior or lateral were lower in case group with statistics significance.②Except standing on firm surface with eyes open,the Romberg Quotient was higher and the area of statokinesigram(SKG),the largest amplitude of the center pressure of body were significantly larger in patients with peripheral vestibular disorders.CONCLUSION The postural stability of patients with peripheral vestibular disorders decreases.It is not only the vestibular function but also vision and proprioception that have defects.So the patients with peripheral vestibular disorders need vision and proprioception compensation which is of importance in the rehabilitation therapy to keep the stability of posture.Posturography test can provide a reference and baseline data for individualized vestibular rehabilitation.
