Summary
The revised electronic Short Physical Performance Battery (eSPPB) kiosk shows excellent validity and reliability compared to the manual SPPB. This technology can help scale physical performance assessments for older adults in community settings.
Area of Science:
- Gerontology
- Biomedical Engineering
- Rehabilitation Science
Background:
- Technology offers potential for scalable physical performance assessments, reducing reliance on trained staff.
- Previous electronic SPPB (eSPPB) versions faced limitations in user-friendliness and scalability for community settings.
- The Short Physical Performance Battery (SPPB) is crucial for assessing mobility and function in older adults.
Purpose of the Study:
- To evaluate the construct validity, agreement, and reliability of a revised eSPPB kiosk against the manual SPPB (mSPPB).
- To assess the eSPPB kiosk's performance in community-dwelling older adults.
- To determine the eSPPB's suitability for large-scale screening of physical performance.
Main Methods:
- Fifty-eight community-dwelling older adults participated, performing both mSPPB and eSPPB assessments.
- Test-retest reliability was assessed in 20 participants after a two-week interval.
- Analyses included correlation, agreement (Bland-Altman plots), and reliability (Intra-class Correlation Coefficients - ICC).
Main Results:
- The eSPPB demonstrated excellent correlation with mSPPB (r=0.922, p<0.001).
- Good agreement was observed between eSPPB and mSPPB (mean difference=0.12).
- Excellent inter-rater reliability (ICC=0.92) and comparable test-retest reliability (ICC=0.61 for eSPPB) were found.
Conclusions:
- The revised eSPPB kiosk exhibits strong construct validity, agreement, and reliability comparable to mSPPB.
- This validated eSPPB technology is suitable for scalable, real-world screening of physical performance, sarcopenia, and frailty in community settings.
- The findings support the broader implementation of eSPPB for geriatric assessments.
