First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested a device called ExAblate that uses focused ultrasound to treat severe hand tremors from essential tremor. Seven people who had already been treated on one side received a second treatment on the other side at least 9 months later. The goal was to see if it was safe and effective for both sides.

What this could mean

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

Active substance: ExAblate device (focused ultrasound)
What this could lead to: If successful, this could offer a non-invasive option to reduce tremors on both sides of the body for people with essential tremor.
What could go wrong: This is a very small early-stage study with only 7 participants, so results may not apply widely. There are also risks of side effects from the procedure.
