A 30-Second chair test could replace long walks for tracking teen arthritis fitness
NCT ID NCT06609837
First seen Oct 20, 2026 · Last updated Oct 21, 2026 · Updated 1 time
Summary
Researchers are studying whether a quick 30-second sit-to-stand test can measure physical fitness in teenagers with juvenile idiopathic arthritis as well as longer tests do. The study compares the chair test with a 6-minute walk and a 10-step stair climb in about 80 teens with arthritis and 116 healthy teens aged 12 to 18. The goal is to find a simpler, more practical way to check how well these young people can move and exercise.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 30-second sit-to-stand test
- What this could lead to
- If it works, clinics could use a quick, simple chair test to track how well teenagers with juvenile arthritis are moving and responding to care.
- What could go wrong
- The test may not match the standard walking test closely enough to replace it, and results in teens may vary with growth and puberty. This is a measurement study, so it offers no direct treatment benefit.
