Ultrasound could take the ouch out of nerve exams
NCT ID NCT03868189
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether using ultrasound during a nerve test (electroneuromyography) can reduce the electrical stimulation needed, making the test less painful. 290 adults were randomly assigned to receive the test with or without ultrasound guidance. The goal was to see if ultrasound helps find the best spot for stimulation, lowering discomfort while still getting accurate results.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ultrasound guidance during electroneuromyography
- What this could lead to
- If it works, this could make nerve tests less uncomfortable for patients by using ultrasound to find the best spot for stimulation.
- What could go wrong
- This is a completed study, but the benefit may be small or not apply to all patients. The intervention is about comfort, not treating a disease.
