Falling in the elderly is a major health problem and may cause severe consequences. Fall risk assessment is important for pre-venting and intervening fall incidence. Inertial Measurement Unit (IMU) has been introduced to evaluate motion/balance function and fall risk among the older people. Some researches indicated that it might have advantages over the usual tools, and can be used in the hospitals, communities, nursing homes, etc. IMU is a good way to measure gait variability, which may be strongly related with the risk of falls.%跌倒是老年人群中常见且后果严重的公共卫生事件,跌倒风险评估是跌倒预防和干预的重要手段。国外研究者将惯性测量单元引入老年人运动/平衡功能测量和跌倒风险的评估。研究提示,它比常用的跌倒评估工具具有优势,可应用于医院、社区和养老机构等。惯性测量单元可能是测量步态变异性的良好方法,步态变异性与跌倒风险相关性很高。
