Overview
Validation study reporting strong correlation (r > 0.92) between Sentinel smartphone measurements and research-grade force plate systems across 30+ gait parameters in the studied cohort.
This study evaluated Sentinel's smartphone-based gait analysis technology against gold-standard force plate measurements, reporting close agreement across a comprehensive set of spatiotemporal gait parameters in the studied cohort.
The study enrolled 150 participants across diverse age groups and mobility levels, conducting simultaneous measurements using both Sentinel's smartphone application and a research-grade force plate system.
In this cohort, results showed strong correlation coefficients (r > 0.92) for key parameters including gait speed, stride length, cadence, and double support time. The study also reported high test-retest reliability (ICC > 0.90) across all measured parameters.
These findings support smartphone-based gait analysis as a promising complement to established laboratory measurement for providing objective movement information outside specialized settings, within the scope of the study population.
