Summary

This study tests whether using a mirror during knee exercises after a total knee replacement helps reduce pain and improve knee movement. Thirty participants who recently had knee replacement surgery will either do exercises while watching their knee in a mirror or with the mirror covered. Researchers will measure pain, range of motion, and walking speed to see if the mirror adds any benefit.

What this could mean

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

Active substance
Mirror therapy
What this could lead to
If it works, this could offer a simple, low-cost way to improve recovery after knee replacement surgery.
What could go wrong
This is a very small, early-stage study with only 30 participants. The sham control uses a covered mirror, so results may be influenced by expectation. It may not show a meaningful benefit.
