App aims to boost exercise adherence for knee pain sufferers
NCT ID NCT06359171
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a smartphone app called ARTHE-e helps people with knee osteoarthritis follow their exercise routines better than standard care. 120 participants used the app for 6 months, and researchers measured exercise adherence using a questionnaire. The goal is to see if the app can improve symptom management and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ARTHE-e smartphone application
- What this could lead to
- If successful, this app could help people with knee osteoarthritis stay consistent with exercise, potentially reducing pain and improving mobility.
- What could go wrong
- This is a small, completed trial with 120 participants, so results may not apply to everyone. The app's effectiveness depends on user engagement, and it may not outperform standard care.
