The aim of this study was to investigate the effect of a visual cognitive additional task on balance performance in young adults with hearing aids (HAs).
Twenty young adult HA users and 20 controls were recruited for the study. Participants were asked to stand on a force plate using computerized dynamic posturography and perform a Sensory Organization Test (SOT) as a balance task under single-task (ST) and dual-task (DT) conditions. The DT condition involved performing a visual cognitive task (Backward Digit Recall) while maintaining balance. Balance performance was measured using equilibrium scores under four different conditions.
The results showed that SOT scores of HA users decreased significantly in the DT compared to the ST ( of Condition 1: < .001; of Condition 4: < .001; of Condition 6: = .001). HA users' SOT scores in the DT condition were statistically significantly lower than controls ( of Condition 1: < .003; of Condition 4: < .009; of Condition 6: = .004). This suggests that the presence of a visual cognitive additional task has a negative impact on balance performance in young adults with HAs.
These findings highlight the importance of considering the impact of cognitive tasks on balance performance in young adults with HAs. Further studies should investigate the specific needs of hearing loss patients in multitasking conditions, including age, degree of hearing loss, and cognitive ability, to develop effective interventions to reduce the risk of falls.
本研究旨在探讨视觉认知附加任务对年轻助听(HA)使用者平衡表现的影响。
本研究招募了 20 名年轻的 HA 用户和 20 名对照者。参与者被要求使用计算机动态姿势描记法站在力板上,并在单任务(ST)和双任务(DT)条件下进行感觉组织测试(SOT)作为平衡任务。DT 条件涉及在维持平衡的同时执行视觉认知任务(倒背数字回忆)。使用四种不同条件下的平衡得分来衡量平衡表现。
结果表明,与 ST 相比,HA 用户在 DT 中的 SOT 得分显著下降(条件 1:<.001;条件 4:<.001;条件 6:=.001)。HA 用户在 DT 条件下的 SOT 得分明显低于对照组(条件 1:<.003;条件 4:<.009;条件 6:=.004)。这表明,存在视觉认知附加任务会对年轻 HA 用户的平衡表现产生负面影响。
这些发现强调了在考虑认知任务对年轻 HA 用户平衡表现的影响时的重要性。进一步的研究应调查在多任务条件下,包括年龄、听力损失程度和认知能力,听力损失患者的特定需求,以制定有效的干预措施来降低跌倒风险。
