Can a computer program replace the ruler for back flexibility tests?
NCT ID NCT07557186
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study will check if a free video-analysis software called Kinovea can accurately measure lower back flexibility. Researchers will record 100 healthy young adults doing a standard flexibility test and compare the software's measurements to the usual method. If it works, Kinovea could offer a simple, low-cost way to track back flexibility without special equipment.
