Carpal tunnel relief: do steroid shots work when nerve tests are normal?
NCT ID NCT04737239
First seen Jun 25, 2026 · Last updated Jul 31, 2026 · Updated 2 times
Summary
This study looks at how well corticosteroid injections relieve carpal tunnel syndrome symptoms in people whose nerve tests (EMG) are normal or only mildly abnormal. Researchers will review past data from 300 patients who received the injection and filled out a questionnaire about their symptoms and daily function. The goal is to help doctors better understand how long the shot provides relief and improve treatment plans.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- corticosteroid injection
- What this could lead to
- If successful, this could help doctors better predict how long symptom relief lasts after a corticosteroid injection for carpal tunnel syndrome, especially in patients with mild or normal nerve tests.
- What could go wrong
- This is a retrospective study, not a controlled trial, so results may be less reliable. It only includes English speakers and may not apply to everyone with carpal tunnel syndrome.
