Twenty-two profoundly deafened adults, implanted with the single-electrode cochlear implant, were involved in a study to observe the effects of cochlear electrical stimulation on the vestibular system. Previous investigators had found evidence that the implant might disrupt postural stability. As there had been no general complaints of dizziness or dysequilibrium by the implant subjects, a study was undertaken to replicate the earlier study and to compare the results to more standardized procedures. A Sono-postural Test was devised from the Ataxia Test Battery for the testing of balance with and without an auditory prosthesis. Electronystagmography was also performed on the subjects before and after surgery as a means of monitoring vestibular status over time. Results from the these tests indicate that the single-electrode implant does not disrupt the balance system to any significant degree. In fact, evidence indicates that postural stability may actually improve with the cochlear implant activated.
22名植入单电极人工耳蜗的极重度耳聋成年人参与了一项研究，以观察耳蜗电刺激对前庭系统的影响。先前的研究人员已发现证据表明该植入物可能会破坏姿势稳定性。由于植入物受试者没有普遍的头晕或平衡失调主诉，因此开展了一项研究以重复早期研究，并将结果与更标准化的程序进行比较。从共济失调测试组中设计了一项声音姿势测试，用于测试有无听觉假体时的平衡情况。还在手术前后对受试者进行了眼震电图检查，作为长期监测前庭状态的一种手段。这些测试结果表明，单电极植入物不会在任何显著程度上破坏平衡系统。事实上，有证据表明，激活人工耳蜗时姿势稳定性实际上可能会改善。
