Magnetic device shows promise for chronic foot pain
NCT ID NCT05922618
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a device that delivers pulsed electromagnetic fields (I-ONE) could help people with complex regional pain syndrome (CRPS) of the foot or ankle. Twenty-eight participants received the device therapy plus standard rehabilitation. Researchers measured pain, swelling, and joint function to see if the combination improved recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- pulsed electromagnetic field therapy (I-ONE device)
- What this could lead to
- If successful, this approach could offer a non-drug option to ease pain and improve function in people with complex regional pain syndrome of the foot or ankle.
- What could go wrong
- This is a small, completed trial with only 28 participants. Results may not apply to everyone, and the device is not a cure—it aims to manage symptoms.
