Abstract：
BACKGROUND: Sensory information obtained from the visual, somatosensory, and vestibular systems is responsible for regulating postural control, and if damage occurs in one or more of these sensory systems, postural control may be altered.
OBJECTIVE: To evaluate and compare the postural sway velocity between children with normal hearing and with sensorineural hearing loss (SNHL), matched by sex and age group, and to compare the postural sway velocity between children with normal hearing and with SNHL, with and without vestibular dysfunction.
METHODS: Cross-sectional study that evaluated 130 children (65 with normal hearing and 65 with SNHL), of both sexes and aged between 7 and 11 years, from public schools of the city of Caruaru, Pernambuco state, Brazil. The postural sway velocity of the center of pressure (COP) was assessed by a force platform, in two directions, anteroposterior (AP) and mediolateral (ML)), in three positions, namely bipedal support with feet together and parallel (parallel feet (PF)), bipedal support with one foot in front of the other (tandem foot (TF)), and single-leg support (one foot (OF)), evaluated with the eyes open and closed.
RESULTS: Children with SNHL demonstrated greater postural sway velocity compared to children with normal hearing in all the positions evaluated, with significant differences in the AP direction, with the eyes open (PF: p = 0.001; TF: p = 0.000; OF: p = 0.003) and closed (PF: p = 0.050; TF: p = 0.005). The same occurred in the ML direction, with the eyes open (PF: p = 0.001; TF: p = 0.000; OF: p = 0.001) and closed (PF: p = 0.002; TF: p = 0.000). The same occurred in relation to vestibular function, where the children with SNHL with an associated vestibular dysfunction demonstrated greater postural sway velocity compared to children with normal hearing in all the positions evaluated, demonstrating significant differences in the AP direction, with the eyes open (TF: p = 0.001; OF: p = 0.029) and eyes closed (PF: p = 0.036; TF: p = 0.033). The same occurred in the ML direction, with the eyes open (TF: p = 0.000) and with the eyes closed (PF: p = 0.008; TF: p = 0.009).
CONCLUSIONS: Children with SNHL demonstrated greater instability of postural control than children with normal hearing in all the directions assessed. Children with SNHL and an associated vestibular dysfunction demonstrated the greatest instability of postural control in this study.

摘要：
背景：从视觉上获得的感官信息，体感,前庭系统负责调节姿势控制，如果这些感觉系统中的一个或多个发生损伤，姿势控制可能会改变。
目的：评估和比较听力正常和感觉神经性听力损失（SNHL）儿童的姿势摇摆速度，按性别和年龄组相匹配，比较听力正常儿童和SNHL儿童的姿势摇摆速度，有和没有前庭功能障碍。
方法：横断面研究评估了130名儿童（65名听力正常，65名SNHL），男女年龄在7至11岁之间，卡鲁鲁市的公立学校，伯南布哥州,巴西。通过力平台评估压力中心（COP）的姿势摇摆速度，在两个方向上,前外侧（AP）和中外侧（ML），在三个位置，即双足支撑与脚在一起和平行（平行脚（PF）），双足支撑，一只脚在另一只脚前面（串联脚（TF）），和单腿支撑（一只脚（OF）），用睁开眼睛和闭眼睛进行评估。
结果：在评估的所有位置，与听力正常的儿童相比，SNHL儿童表现出更大的姿势摇摆速度，在AP方向上存在显著差异，睁开眼睛（PF：p=0.001；TF：p=0.000；OF：p=0.003）和闭合（PF：p=0.050；TF：p=0.005）。同样发生在ML方向，睁开眼睛（PF：p=0.001；TF：p=0.000；OF：p=0.001）和闭合（PF：p=0.002；TF：p=0.000）。前庭功能也发生了同样的情况，在评估的所有位置中，与听力正常的儿童相比，患有SNHL并伴有前庭功能障碍的儿童表现出更大的姿势摇摆速度，表明AP方向存在显著差异，睁开眼睛（TF：p=0.001；OF：p=0.029）和闭眼（PF：p=0.036；TF：p=0.033）。同样发生在ML方向，睁开眼睛（TF：p=0.000）和闭眼（PF：p=0.008；TF：p=0.009）。
结论：在评估的所有方向上，SNHL患儿的姿势控制比听力正常的患儿更不稳定。在这项研究中，患有SNHL和相关前庭功能障碍的儿童表现出姿势控制的最大不稳定性。
