Agreement of Clinical Grade and Laboratory Grade Force Plates for Countermovement Jump Metrics in Youth Athletes.

Each participant performed only one jump per device, which increases the chance that natural variability in performance skewed the results. The jumps were performed separately on each device rather than simultaneously, so differences might reflect how the athlete jumped rather than how the devices measured. The study used custom software to analyze raw data rather than the devices' proprietary algorithms, which may not reflect how clinicians typically use these systems. Results apply only to these specific force plate models and may not extend to other clinical devices.

The authors report no conflicts of interest.

Do not assume all advanced metrics from clinical force plates match laboratory standards. While jump height and peak force are comparable, impulse and some rate of force development measures differ significantly and cannot be used interchangeably.
