Brain zap tuning: could different electrical frequencies protect hand function during tumor surgery?
NCT ID NCT05023434
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study involves 20 people undergoing awake brain surgery for tumors near the hand movement area. Surgeons will test different electrical stimulation frequencies (10 to 250 Hz) to see which ones best identify or even improve hand movement. The goal is to develop a more precise way to map the brain during surgery, potentially reducing the risk of permanent hand weakness.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Intraoperative direct electrical stimulation with varied parameters
What this could lead to
If successful, this could help surgeons better map hand movement areas during brain surgery, potentially reducing the risk of permanent hand weakness after tumor removal.
What could go wrong
This is a very small early study (20 people) focused on measurement methods, not treatment. It may not lead to any change in patient outcomes or surgical practice.
