High-Intensity Focused Electromagnetic Therapy Combined With Foot Core Training for Pronated Foot

Overview

The objective of this trial is to assess the effects of high-intensity focused electromagnetic therapy combined with foot core training targeting the intrinsic foot muscles on plantar load, static foot posture, intrinsic foot muscle morphology and intrinsic foot muscle activation in individuals with pronated foot. The main questions it aims to answer are: Question 1: To compare changes in plantar load following interventions of high-intensity focused electromagnetic therapy combined with foot core training, high-intensity focused electromagnetic therapy alone, and sham high-intensity focused electromagnetic therapy combined with foot core training. Question 2: To compare changes in static foot posture, intrinsic foot muscle morphology, and intrinsic foot muscle activation following interventions of high-intensity focused electromagnetic therapy combined with foot core training, high-intensity focused electromagnetic therapy alone, and sham high-intensity focused electromagnetic therapy combined with foot core training. Question 3: To assess the effects of each intervention on plantar load, static foot posture, intrinsic foot muscle morphology, and intrinsic foot muscle activation in individuals with pronated foot. Participants will undergo stimulation of their intrinsic foot muscles through high-intensity focused electromagnetic therapy, and they will also be required to isometrically contract their intrinsic foot muscles during the designated exercise program. Researchers will assess the effects of high-intensity focused electromagnetic therapy combined with foot core training by evaluating plantar load during walking, static foot posture, intrinsic foot muscle morphology and intrinsic foot muscle activation during walking.

The objective of this trial is to assess the effects of high-intensity focused electromagnetic therapy combined with foot core training targeting the intrinsic foot muscles on plantar load, static foot posture, intrinsic foot muscle morphology and intrinsic foot muscle activation in individuals with pronated foot. The main questions it aims to answer are: Question 1: To compare changes in plantar load following interventions of high-intensity focused electromagnetic therapy combined with foot core training, high-intensity focused electromagnetic therapy alone, and sham high-intensity focused electromagnetic therapy combined with foot core training. Question 2: To compare changes in static foot posture, intrinsic foot muscle morphology, and intrinsic foot muscle activation following interventions of high-intensity focused electromagnetic therapy combined with foot core training, high-intensity focused electromagnetic therapy alone, and sham high-intensity focused electromagnetic therapy combined with foot core training. Question 3: To assess the effects of each intervention on plantar load, static foot posture, intrinsic foot muscle morphology, and intrinsic foot muscle activation in individuals with pronated foot. Eligible participants will be randomly assigned to one of three groups: the high-intensity focused electromagnetic therapy combined with foot core training group, the high-intensity focused electromagnetic therapy group, or the sham high-intensity focused electromagnetic therapy combined with foot core training group. High-intensity focused electromagnetic therapy sessions will last for 20 minutes each, while the foot core training program will comprise 4 exercises, with 10 repetitions per set and 3 sets per session for each exercise. Participants will undergo these interventions twice a week over a 6-week period. Plantar load and electromyographic signals of the abductor hallucis muscle during gait, ultrasonography for morphological analysis of the intrinsic foot muscles, and static foot posture will be evaluated at baseline and 6 weeks following the intervention.
