Summary

This study tested whether a home exercise program guided by the TRAK app could improve pain and function in people with knee osteoarthritis, compared to doing the same exercises without the app. Fifty patients over age 45 with knee pain took part. The goal was to see if telerehabilitation could be a convenient, effective alternative to in-person physiotherapy.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
exercise program delivered via TRAK telerehabilitation software
What this could lead to
If successful, this could show that a home-based, app-guided exercise program is as good as or better than standard in-person physiotherapy for knee osteoarthritis.
What could go wrong
This is a small, completed trial with only 50 participants, so results may not apply to everyone. The intervention relies on having a smartphone and internet access, which may limit who can benefit.
