Is this trial a fit for you?

Likely a good fit

Adults aged 18-50 with functionally flat feet (pes planus).

Probably not a fit

Individuals with acute leg injuries, diabetes, vascular disorders of the lower limbs, skin lesions on the lower leg or foot, metal implants near the stimulation site, cardiac pacemakers, or other conditions posing risk or interfering with results may not benefit.

What this trial studies

This interventional study applies repetitive peripheral magnetic stimulation (rPMS) to the invertor muscles of the foot in adults with flat feet, three times per week for 12 weeks. Participants are randomized to receive either active rPMS or no stimulation, with both groups undergoing the same measurements at baseline, 6 weeks, and 12 weeks. The primary outcome is the change in medial longitudinal arch height during gait, measured by dynamic navicular drop, while secondary outcomes include isometric inversion torque and tibialis posterior muscle morphology via ultrasound. The trial aims to determine if rPMS can strengthen foot invertors and alter arch mechanics to potentially improve function and reduce symptoms.

Why it matters

Potential benefit: If successful, rPMS could help improve arch support and foot muscle strength in adults with flat feet.

How similar studies have gone: Previous research in similar noninvasive neuromodulation approaches has shown potential improvements in muscle performance, but the specific use of rPMS for foot invertors and MLA height remains exploratory.
