Product Overview

Automated SPPB Administration

High-precision, continuous measurement enabled by LiDAR technology through a fully automated process. No wearable devices or disposable components required.

Typical test time: under 3 minutes.

Automatically generates a report sheet after each SPPB, including SPPB results and derived indicators such as an estimated frailty index and a physiological age metric.

The Challenge

Manual SPPB Assessment Limitations

Human-Related Errors

  • ✗ Reaction time variability: Manual stopwatch timing introduces 100-300ms error per measurement
  • ✗ Observer bias: Different testers may interpret protocol steps inconsistently
  • ✗ Recording mistakes: Transcription errors when logging results

Protocol Compliance Issues

  • ✗ Starting conditions: Inconsistent application of static vs dynamic start protocols
  • ✗ Position verification: Subjective assessment of balance positions
  • ✗ Multi-site studies: Inter-rater reliability challenges across institutions
AndanteFit Solution

Standardization Through Automation

AndanteFit eliminates examiner-related variability and ensures protocol compliance through sensor-based objective measurement.

Performance Metrics

Evidence of Efficiency

<3 min

Average test time per participant. Compared to 5-8 minutes with conventional manual administration (Jung et al., 2019).

r = 0.92

Correlation with manual SPPB. High agreement demonstrated across all components (Park et al., 2021).

ICC > 0.90

Inter-rater reliability. Consistent results across different testers and institutions (Hernandez et al., 2022).
