The aim of this study was to assess the neuromuscular control of adolescents with late unilateral cochlear implantation and compare them to adolescents with hearing aids (HAs) while performing a balance task on a platform with the conditions of an activated hearing device (cochlear implant (CI)/HAs) with eyes opened/closed (EO/EC). Forty-eight adolescents with hearing loss participated in the study and were divided into SG (unilateral CI and HA) and CG (bilateral HA). The evaluation of the postural stability was performed with a force plate during two repeating testing trials with EO/EC. SG was characterized by greater values of vCOP compared to CG (EO), while, in CG, greater values of vCOP were noted in the second trial. The type of hearing device was found to be related to the values of area (EO) ( < 0.001), which were always greater in SG, regardless of the visual perception. Late unilateral CI may impact the activation of different models of the auditory compensatory mechanism than HA, which is related to neuromuscular control. The values of vCOP can be predicted by age in late-CI individuals. Visual perception seems not to be related to the values of the area, which can be impacted both by CI and HA.
本研究的目的是评估单侧晚期人工耳蜗植入青少年的神经肌肉控制能力，并将其与佩戴助听器（HA）的青少年进行比较，同时在平台上进行平衡任务，条件为激活听力设备（人工耳蜗（CI）/HA）且眼睛睁开/闭合（EO/EC）。48名听力损失青少年参与了该研究，并被分为SG组（单侧CI和HA）和CG组（双侧HA）。在两次重复测试试验中，使用测力板对姿势稳定性进行评估，测试条件为EO/EC。与CG组（EO）相比，SG组的视觉运动觉中心压力（vCOP）值更高，而在CG组中，第二次试验的vCOP值更高。研究发现，听力设备类型与面积值（EO）相关（<0.001），无论视觉感知如何，SG组的面积值总是更高。晚期单侧CI可能比HA影响不同模式的听觉代偿机制的激活，这与神经肌肉控制有关。晚期CI个体的vCOP值可通过年龄预测。视觉感知似乎与面积值无关，面积值可能受到CI和HA的影响。
