This study aimed to evaluate if hearing performance is a predictor of postural control in cochlear implant (CI) users at least six months after surgery.
Cross-sectional study including (CI) recipients with post-lingual deafness and controls who were divided into the following groups: nine CI users with good hearing performance (G+), five CI users with poor hearing performance (G-), and seven controls (CG). For each patient, computerized dynamic posturography (CDP) tests, a sensory organization test (SOT), and an adaptation test (ADT) were applied as dual task performance, with first test (FT) and re-test (RT) on the same day, including a 40-60min interval between them to evaluate the short-term learning ability on postural recovery strategies. The results of the groups were compared.
Comparing the dual task performance on CDP and the weighted average between all test conditions, the G+ group showed better performance on RT in SOT4, SOT5, SOT6, and CS, which was not observed for G- and CG. The G- group had significantly lower levels of short-term learning ability than the other two groups in SOT5 (p=0.021), SOT6 (p=0.025), and CS (p=0.031).
The CI users with good hearing performance had a higher index of postural recovery when compared to CI users with poor hearing performance.
本研究旨在评估听力表现是否是人工耳蜗（CI）使用者术后至少六个月姿势控制的预测指标。
横断面研究，纳入语后聋的CI接受者和对照组，分为以下几组：九名听力表现良好的CI使用者（G+）、五名听力表现较差的CI使用者（G-）和七名对照组（CG）。对每位患者进行计算机动态姿势描记法（CDP）测试、感觉组织测试（SOT）和适应性测试（ADT）作为双重任务表现，在同一天进行首次测试（FT）和重新测试（RT），两者之间间隔40-60分钟以评估姿势恢复策略的短期学习能力。比较各组结果。
比较CDP上的双重任务表现以及所有测试条件下的加权平均值，G+组在SOT4、SOT5、SOT6和CS的RT中表现更好，G-组和CG组未观察到这种情况。在SOT5（p=0.021）、SOT6（p=0.025）和CS（p=0.031）中，G-组的短期学习能力水平明显低于其他两组。
与听力表现较差的CI使用者相比，听力表现良好的CI使用者姿势恢复指数更高。
