Alterations of balance are a growing public health problem as they affect one in three adults over the age of 65, and one in two over the age of 80. Identifying the factors that affect postural stability is essential in designing specific interventions to maintain the independence and mobility of older people. The aim of this review was to understand the use of accelerometers in order to assess the balance in older people. Analyzing the most appropriate evaluation methodology and protocolizing it will optimize the processes of early identification of balance alterations. However, quantitative assessment methods of balance are usually limited to a laboratory environment, a factor that can be overcome by accelerometers. A systematic search was carried out across eight databases where accelerometers were employed to assess balance in older people. Articles were excluded if they focused on sensor design and did not measure balance or apply the technology on targeted participants. A total of 19 articles were included for full-text analysis, where participants took part in the balance evaluation monitored by accelerometers. The analysis of spatio-temporal parameters and the magnitude of the accelerations recorded by the devices were the most common study variables. Accelerometer usage has potential to positively influence interventions based on physical exercise to improve balance and prevent falls in older people.
平衡能力的改变是一个日益严重的公共卫生问题,因为它影响了三分之一 65 岁以上的成年人,以及二分之一 80 岁以上的成年人。确定影响姿势稳定性的因素对于设计特定的干预措施以维持老年人的独立性和流动性至关重要。本综述的目的是了解加速度计在评估老年人平衡能力中的应用。分析最合适的评估方法并将其规范化将优化早期识别平衡改变的过程。然而,平衡的定量评估方法通常仅限于实验室环境,而加速度计可以克服这一限制。我们在八个数据库中进行了系统搜索,这些数据库中使用了加速度计来评估老年人的平衡能力。如果文章仅专注于传感器设计,而不测量平衡或在特定参与者身上应用该技术,则将其排除在外。共有 19 篇文章被纳入全文分析,其中参与者参与了由加速度计监测的平衡评估。最常见的研究变量是时空参数的分析和设备记录的加速度幅度。加速度计的使用有可能积极影响基于体育锻炼的干预措施,以改善老年人的平衡能力并预防跌倒。
