NCT ID NCT06145646
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how the temperature of your muscles changes the way they appear on an ultrasound. Researchers will heat a leg muscle, then take ultrasound images as it cools down. The goal is to make muscle ultrasound a more reliable tool for diagnosing conditions. 30 healthy adults aged 18-65 will participate.
