Children with hearing deficits frequently have delayed motor development. The purpose of this study was to evaluate saccular function in children with hearing impairments using the Vestibular Evoked Myogenic Potential (VEMP). The impact of the saccular hypofunction on the timely maturation of normal balance strategies was examined using the Movement Assessment Battery for Children (Movement ABC). Thirty-three children with bilateral severe/profound hearing impairment between 4 and 7 years of age were recruited from a three-state area. Approximately half of the sample had one or bilateral cochlear implants, one used bilateral hearing aids, and the rest used no amplification. Parents reported whether the hearing impairment was diagnosed within the first year or after 2 years of age. No VEMP was evoked in two thirds of the hearing impaired (HI) children in response to the bone-conducted stimulus. Children who were reportedly hearing impaired since birth had significantly poorer scores when tested with the Movement ABC.
听力有缺陷的儿童往往运动发育迟缓。本研究的目的是使用前庭诱发肌源性电位（VEMP）评估听力障碍儿童的球囊功能。使用儿童运动评估量表（Movement ABC）研究了球囊功能减退对正常平衡策略及时成熟的影响。从一个三州地区招募了33名4至7岁的双侧重度/极重度听力障碍儿童。大约一半的样本植入了一个或双侧人工耳蜗，一名使用双侧助听器，其余未使用任何听力放大设备。家长报告听力障碍是在出生后第一年内还是2岁以后被诊断出来的。三分之二的听力受损（HI）儿童对骨导刺激无VEMP反应。据报告自出生就听力受损的儿童在使用Movement ABC进行测试时得分明显更低。
