Heel pain mystery: is the brain making it worse?
NCT ID NCT07640620
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether the brain and nervous system (central sensitization) play a role in the pain of plantar fasciitis, a common cause of heel pain. Researchers will measure pain sensitivity, ultrasound images of the foot, and psychological factors in 128 adults with the condition. The goal is to better understand what drives pain in these patients, which could guide future treatments.

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could help doctors better understand why some people with plantar fasciitis have persistent pain, potentially leading to more targeted treatments.
- What could go wrong
- This is an observational study, not a treatment trial. It will not directly test any new therapy, and results may not change current care.
