NCT ID NCT06742814
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether using a stress ball during local anesthesia for hand surgery can lower anxiety and pain. 74 adults were randomly assigned to either squeeze a stress ball or receive standard care. Researchers measured heart rate variability and self-reported anxiety and pain levels. The goal is to find a simple, drug-free way to improve the surgical experience.

- Active substance
- stress ball
- What this could lead to
- If it works, this could give doctors a simple, no-drug way to help patients feel calmer and less pain during minor surgeries.
- What could go wrong
- This is a small, completed trial with only 74 people. The effect may be small or not work for everyone, and stress balls are not a substitute for medical anxiety treatment.
