Summary

This pilot study tests whether a home-based brain stimulation device (tDCS) can help people recover better after total knee replacement. About 70 adults scheduled for knee surgery will use the device before and after their operation. The main goal is to see if the study is feasible, not yet to prove it works.

What this could mean

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

Active substance: transcranial direct current stimulation (tDCS) device
What this could lead to: If it works, this could point toward a simple, non-drug way to manage pain after knee replacement and lower the risk of long-term pain.
What could go wrong: This is a small pilot study testing feasibility, not effectiveness. The approach is experimental, and results may not lead to a proven treatment.
