This study aimed to investigate the influence of visual and auditory cognitive tasks on postural balance in adolescents with intellectual disabilities (ID). Participants included two groups: a trained group (n = 11) with experience in athletic activities and a sedentary group (n = 14). The experiment used a comparative cross-sectional design, with data collection involving single-task (ST) and Visual dual-task (VDT), and auditory dual-task (ADT) conditions in both firm and foam surface conditions. Cognitive tests included the Working Memory Test (WMT) and the Selective Attention Test (SAT). Results revealed that the trained group demonstrated significantly superior balance performance (p < 0.05). During the SAT, VDT conditions had lower center of pressure (CoP) values than ADT conditions in the sedentary group (p < 0.01), this result was observed in the training group only in the WMT, suggesting greater postural instability during ADT. These findings highlight the complex relationship between cognitive function and motor control in adolescents with ID, highlighting the potential benefits of regular physical activity interventions to improve postural balance abilities in this population.
本研究旨在探讨视觉和听觉认知任务对智障青少年(ID)姿势平衡的影响。参与者分为两组:有运动活动经验的训练组(n=11)和久坐组(n=14)。实验采用对比性的横断面设计,在硬面和泡沫面条件下分别进行单任务(ST)和视觉双重任务(VDT)以及听觉双重任务(ADT)条件下的数据收集。认知测试包括工作记忆测试(WMT)和选择性注意测试(SAT)。结果表明,训练组的平衡表现明显更好(p<0.05)。在 SAT 中,与 ADT 条件相比,久坐组的 VDT 条件下的压力中心(CoP)值更低(p<0.01),而仅在 WMT 中,训练组观察到这一结果,表明 ADT 期间姿势更不稳定。这些发现强调了智障青少年认知功能和运动控制之间的复杂关系,突出了定期进行身体活动干预的潜在益处,以提高该人群的姿势平衡能力。
