Abstract

Abstract Purpose This study investigated the accuracy of an accelerometer-based smartphone application for predicting the risk of falls in older adults. Methods Eighty community-dwelling older adults (70.05 ± 4.5 years) were assessed using an accelerometer-based smartphone application for balance assessment at baseline, which included 1) the Modified Clinical Test of Sensory Interaction in Balance (MCTSIB), 2) a single-leg stance (SLST), and 3) limit of stability (LOS) test. The fall incidence during a 6-month follow-up was recorded. The area under the receiver operating characteristic curve (AUC) was used to determine accuracy. Results The accuracy in predicting falls of all assessments was high (AUC = 0.78–0.99). The MCTSIB had the highest AUC (0.99) compared with the SLST (0.86) and the LOS test (0.78). The MCTSIB had a cutoff score of 8.04, sensitivity of 100%, and specificity of 98%. Conclusion The accelerometer-based smartphone application could predict falls in older adults with excellent accuracy.

使用基于加速度计的智能手机应用程序预测老年人跌倒

摘要目的研究基于加速度计的智能手机应用程序预测老年人跌倒风险的准确性。方法采用基于加速度计的智能手机平衡评估应用程序，对80名社区老年人(70.05±4.5岁)进行基线平衡评估，包括1)改进的临床平衡感觉相互作用测试(MCTSIB)， 2)单腿站立(SLST)和3)稳定性极限(LOS)测试。在6个月的随访期间记录跌倒发生率。用受试者工作特征曲线下面积(AUC)来确定准确度。结果各项评估预测跌倒的准确率均较高(AUC = 0.78 ~ 0.99)。MCTSIB的AUC(0.99)高于SLST(0.86)和LOS(0.78)。MCTSIB的临界值为8.04，敏感性为100%，特异性为98%。结论基于加速度计的智能手机应用程序能够准确预测老年人跌倒。

期刊介绍： This comprehensive journal is recognized for its useful balance of research and clinical practice articles. For more than twenty five years Physical & Occupational Therapy in Geriatrics has functioned as a forum for allied health professionals as well as others with a focus on rehabilitation of the geriatric client to share information, clinical experience, research, and therapeutic practice. Each issue focuses on current practice and emerging issues in the care of the older client, including rehabilitation and long-term care in institutional and community settings, and innovative programming; the entire range of problems experienced by the elderly; and the current skills needed for working with older clients.
