Summary
This pilot study tests whether a non-invasive brain stimulation technique called transcranial direct current stimulation (tDCS) can help people recover better after total knee replacement surgery. The device delivers a mild electrical current to the scalp to reduce pain and opioid use. The study will enroll 70 adults scheduled for knee replacement and will assess whether the home-based tDCS protocol is feasible and acceptable.

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 provide a non-drug, at-home method 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 may not reduce pain or opioid use in practice.
