117 Study of Development and Validation of the Multi-Sensor based Kiosk Performing Short Physical Performance Battery Automatically

Abstract

Background: Short physical performance battery (SPPB) is a well-accepted clinical test to assess vulnerability in older adults. We aimed to develop and validate a multi-sensor based kiosk (e-SPPB kiosk) which can perform automated measurement for SPPB. Methods: The e-SPPB kiosk was developed to measure 3 components of SPPB of standing balance, gait speed, and chair stand test with embedded sensors and algorithms. Feasibility and reliability of the e-SPPB kiosk was assessed with the manually measured SPPB (m-SPPB) by a physical therapist in participants aged 65 or older recruited from the outpatient rehabilitation clinic of the Seoul National University BundangHospital, Seongnam, Korea, from November 2018 to April 2019. Results: In 34 participants with mean age of 73.6 (standard deviation [SD] 5.4), mean of e-SPPB total score was 10.1 (SD 2.2) and mean of m-SPPB total score was 10.2 (SD 2.3). Concordance between e-SPPB and m-SPPB total score was 0.94 (P<0.001) and agreement by Kappa was 0.65 (P<0.001). Agreements for components of e-SPPB and m-SPPB were 0.68 (P<0.001), 0.73 (P<0.001), 0.92 (P<0.001) for standing balance, gait speed and chair stand test, respectively. Conclusion: In older adults, physical performance measured by the e-SPPB kiosk correlated to m-SPPB measured by a single physical therapist. In multicenter studies for older people with physical performance as an outcome or selection criterion, e-SPPB kiosk can be used to reduce possible inter-rater variabilities of SPPB.
