Could a free video app replace expensive motion-capture labs?
NCT ID NCT07676149
First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time
Summary
This study checks whether Kinovea, a free video analysis software, can consistently measure knee and hip angles when people stand up from a chair. Healthy volunteers aged 18 to 45 will be recorded doing sit-to-stand movements, and three physiotherapists will analyze the videos separately at different times. The goal is to see if the software gives the same results each time and between different users.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If reliable, Kinovea could offer a low-cost, accessible way for clinicians to assess movement without expensive equipment.
- What could go wrong
- This is a small, early-stage reliability study in healthy volunteers only. Results may not apply to people with movement disorders or injuries.
