The aim of this study was to compare the static and dynamic balance performance of deaf children with and without cochlear implants. This is a cross-sectional study of 145 school children, aged between 7 and 12 years comprising 85 children with congenital or early acquired bilateral profound sensorineural hearing loss (the hearing loss group) and 60 normal hearing aged-matched control counterparts were assessed using the balance subtest of Bruininks-Oseretsky test of Motor Proficiency (BOTMP). The hearing loss group, 50 without cochlear implants (the non-implant group) and 35 of them with unilateral cochlear implants (the implant group) were recruited from schools for the deaf and normal hearing children (the control group) randomly selected from two randomly selected elementary schools of Tehran city. The scores were analyzed using one-way ANOVA. The total score of deaf children especially the implant group were significantly lower than the control group )P<0.001). The balance performance of the control group was better than the implant group in all of the items as well as the non-implant group except the fourth tested item (walking forward on a line) (P<0.05). The balance score of the implant group was significantly lower than the non-implant group except for the third tested item (standing on the preferred leg on a balance beam with eyes closed). The findings suggested that deaf children, specifically those with cochlear implants are at risk for motor and balance deficits. Thus, vestibular and motor evaluations, as well as interventions to improve balance and motor skills, should be prioritized for this population.
本研究的目的是比较植入和未植入人工耳蜗的聋童的静态和动态平衡能力。这是一项横断面研究，对145名7至12岁的学童进行了评估，其中包括85名患有先天性或早期获得性双侧重度感音神经性听力损失的儿童（听力损失组），以及60名年龄匹配的听力正常的对照儿童，使用布吕宁克斯-奥塞雷茨基运动能力测试（BOTMP）的平衡子测试进行评估。听力损失组中，50名未植入人工耳蜗（非植入组）和35名植入单侧人工耳蜗（植入组）的儿童来自聋校，对照儿童（对照组）则从德黑兰市随机挑选的两所小学中随机选取的听力正常儿童中招募。使用单因素方差分析对得分进行分析。聋童尤其是植入组的总分显著低于对照组（P<0.001）。除了第四个测试项目（沿直线向前行走）外，对照组在所有项目中的平衡能力均优于植入组和非植入组（P<0.05）。除了第三个测试项目（闭眼在平衡木上用优势腿站立）外，植入组的平衡得分显著低于非植入组。研究结果表明，聋童，尤其是植入人工耳蜗的聋童存在运动和平衡缺陷的风险。因此，对于这一群体，应优先进行前庭和运动评估，以及改善平衡和运动技能的干预措施。
