What this Trial Is About

Researchers are studying the effects of repetitive peripheral magnetic stimulation (rPMS) on foot invertor muscle strength, shape, and the height of the medial longitudinal arch (MLA) in adults with flat feet. The study aims to find out if rPMS can improve foot function and prevent musculoskeletal problems related to flat foot deformity by strengthening key muscles like the tibialis posterior, which supports the arch and affects gait efficiency. Participants in the experimental group will receive rPMS applied non-invasively to the invertor muscles of the foot three times a week for 12 weeks. Stimulation targets the upper third of the shin and intrinsic foot muscles simultaneously with a foot stimulator. The control group will not receive stimulation but will follow the same schedule for measurements. Both groups will be assessed at baseline, 6 weeks, and 12 weeks. During the study, participants will undergo ultrasound imaging, navicular drop assessment, clinical evaluation of the plantar arch index, and isometric strength testing of the foot invertor muscles at three different times. The main measure is the change in MLA height, with secondary measures including changes in foot invertor muscle strength and muscle structure. This study will last for 12 weeks with monitoring of muscle and foot arch changes to evaluate the effects of rPMS.

Your Study Journey

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

1 visit (in-person)

Treatment

Duration - 12 weeks

Participants receive repetitive peripheral magnetic stimulation (rPMS) of the foot invertor muscles three times per week for 12 weeks. During this time, participants perform isometric inversion contractions and short-foot exercises to enhance neuromuscular activation. The stimulation targets both extrinsic and intrinsic foot muscles.

Three sessions per week for 12 weeks

Follow-up

Duration - 12 weeks (concurrent with treatment period)

Participants undergo assessments including ultrasound imaging, navicular drop assessment, clinical evaluation of the plantar arch index, and isometric strength testing of the foot invertor muscles at baseline, after 6 weeks, and after 12 weeks to evaluate changes from the intervention.

3 assessment visits: at baseline, Week 6, and Week 12
