Abstract

The short physical performance battery (SPPB) is a widely used clinical assessment tool to evaluate physical function in older adults. However, the manual measurement of the SPPB presents difficulties in terms of standardization and accessibility. To address these limitations, an earphone-shaped SPPB assessment device, named B-Lab, was developed. To validate the device, 45 healthy participants aged 60 years and older were recruited, and the SPPB results obtained through the B-Lab were compared with those from the manual method. Results showed high agreement between the two methods, with an intraclass correlation coefficient of 0.87 and 0.68 for the first and second trials, respectively. The reliability of the B-Lab was also comparable to that of the manual method. Overall, the B-Lab showed potential as an alternative for assessing SPPB scores. It enables patients to assess their physical function without hospital visits, and is expected to contribute to the development of a more effective healthcare environment.

一种基于耳机的测量老年人短时体能电池的系统的开发和验证

短时间体能测试（SPPB）是一种广泛应用于老年人身体功能的临床评估工具。然而，手工测量SPPB在标准化和可及性方面存在困难。为了解决这些限制，开发了一种耳机形状的SPPB评估装置，名为B-Lab。为了验证该装置，我们招募了45名60岁及以上的健康参与者，并将B-Lab获得的SPPB结果与手工方法的结果进行了比较。结果表明，两种方法之间具有较高的一致性，第一次和第二次试验的类内相关系数分别为0.87和0.68。B-Lab的可靠性也与手工方法相当。总的来说，B-Lab显示了作为评估SPPB分数的替代方法的潜力。它使患者能够在不去医院的情况下评估自己的身体功能，并有望促进更有效的医疗保健环境的发展。
