About this study
Official title: Effects of High-Intensity Focused Electromagnetic Therapy Combined With Foot Core Training on Dynamic Foot Function in Individuals With Pronated Foot
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 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.

Questions about this trial
What is this clinical trial studying?
A study testing High-intensity focused electromagnetic therapy and Foot core training in people with Flexible Flatfoot, run by National Taiwan University Hospital at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 30 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from baseline in plantar load at week 6 (time frame: baseline, week 6). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06401954, which also lists 21 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jun 2026; AzTrials last refreshed its copy on 2 Nov 2026.
