摘要
背景:听力障碍是老龄化社会中一个日益沉重的负担。听力损失与认知能力下降以及平衡和步态减弱有关。因此,听力受损也会影响双重任务(DT)。本综述旨在总结有听力障碍的老年人在保持平衡或行走时双重任务能力下降的证据:方法:根据 PRISMA 指南,使用 MEDLINE、APA Psych-Info 和 Web of Science 进行系统文献研究。纳入标准为独立生活的听力受损老年人(≥ 60 岁),使用 DT 范式测试听力受损老年人的平衡或行走状况:在数据库中找到了 N = 57 项研究。共纳入 8 项研究(N = 456 名参与者(58% 为女性),包括 n = 200 名不同程度听力损失的老年听障人士)。大多数纳入研究的听力损失阈值为轻度听力损失,纯音平均值(0.5-4 kHz)≥ 25 和结论:与无听力障碍者相比,有听力障碍者的 DT 成绩下降更为明显。这意味着听力受损的老年人可能需要特定的干预措施来减少认知-运动干扰(CMI),以便在需要同时管理认知和运动任务的日常生活中保持平衡控制或行走稳定性。然而,考虑到所有结果,还需要进一步研究这一目标群体的认知运动干扰的潜在机制:本综述已在 Prospero 注册,注册号为 CRD42022340232。
The impact of cognitive-motor interference on balance and gait in hearing-impaired older adults: a systematic review.
Background: Hearing impairments are a rising burden in our aging society. Hearing loss is associated with reduced cognitive performance as well as decrements in balance and gait. Therefore, impaired hearing affects also dual tasking (DT). The aim of this review is to summarize the evidence for DT performance decrements of older adults with hearing impairments during maintaining balance or walking.
Methods: The systematic literature research according to PRISMA guidelines was conducted using MEDLINE, APA Psych-Info, and Web of Science. Inclusion criteria were: Independent living older people ≥ 60 years with hearing impairments, use of a DT paradigm to test hearing impaired older adults within a balance or walking condition.
Results: N = 57 studies were found within the databases. Eight studies were included (N = 456 participants (58% women), including n = 200 older hearing-impaired persons with different levels of hearing loss). Most of the included studies oriented their inclusion criteria for hearing-impairments at thresholds for mild hearing loss with Pure Tone Average (0.5-4 kHz) ≥ 25 and < 40 dB. Three of the studies focused on DT balance performance and five used DT walking comparing participants with and without hearing loss. For DT balance and gait performance, higher decrements for the hearing-impaired group were observed compared to healthy older adults. Performance decrements were accompanied by reduced compensatory strategies in balance performance.
Conclusion: More pronounced decrements in DT performance were observed for participants with hearing impairments compared to those without. This implies that hearing-impaired older adults might need specific interventions to reduce the cognitive-motor interference (CMI) to maintain balance control or walking stability in daily situations that require managing of cognitive and motor tasks simultaneously. However, taking all results into account the underlying mechanisms of CMI for this target group needs to be further examined.

期刊介绍:
European Review of Aging and Physical Activity (EURAPA) disseminates research on the biomedical and behavioural aspects of physical activity and aging. The main issues addressed by EURAPA are the impact of physical activity or exercise on cognitive, physical, and psycho-social functioning of older people, physical activity patterns in advanced age, and the relationship between physical activity and health.
