All subjects with implanted cochlear stimulators demonstrated evidence of abnormal postural stability without their stimulators activated. Instability increased when they were tested with cochlear stimulation units turned on, and additional instability was demonstrated in four of these subjects when tested in noise. These findings suggest that the electrical stimulation delivered by the cochlear prosthesis is not limited to the auditory system. The precise characteristics of electrical stimulation devices designed for stimulations limited to the cochlea and their spurious effects upon motor performance should be investigated. The design of future intralabyrinthine auditory electrical prostheses must include hardware designs and stimulus paradigms that avoid undesirable vestibular system stimulation.
所有植入人工耳蜗刺激器的受试者在刺激器未激活时均表现出姿势稳定性异常的迹象。当打开人工耳蜗刺激单元进行测试时，不稳定性增加，其中四名受试者在噪声环境中测试时表现出额外的不稳定性。这些发现表明，人工耳蜗传递的电刺激并不局限于听觉系统。应研究专为限于耳蜗的刺激设计的电刺激装置的精确特性及其对运动表现的虚假影响。未来内耳听觉电假体的设计必须包括避免不良前庭系统刺激的硬件设计和刺激模式。
