This may influence the way the kneecap sits or tilts in relation to the thigh bone. Foot orthoses are often used for knee and foot problems, but it is not clear whether they directly change kneecap position when a person is standing and bearing weight.\n\nThe study will include adults with flexible flatfoot. Each participant will have low-dose, three-dimensional weight-bearing cone beam CT scans while standing in different foot positions: their natural foot position, with foot orthoses, and with foot orthoses inside a neutral running shoe. Scans will be performed with the knees straight and slightly bent.\n\nThe main hypothesis is that correcting a pronated flat foot position with foot orthoses will reduce sideways tilt and outward shift of the kneecap compared with the participant's natural foot position. The study will also examine whether changes in foot position are accompanied by changes in lower-limb rotation.\n\nThis study does not test whether foot orthoses reduce pain. Instead, it is designed to understand the immediate mechanical effect of foot correction on kneecap position.",[27,28,29],"Patellofemoral Alignment","Patellofemoral Joint","Flatfoot",[29,31,32,33,34,35,36,37,38,39],"Foot pronation","Foot orthoses","Patellofemoral alignment","Patellar tilt","Kneecap position","Lower-limb alignment","Lower-limb rotation","Weight-bearing Imaging","Cone-Beam Computed Tomography","NOT_YET_RECRUITING","2026-06-25",{"date":43,"type":44},"2026-07-01","ACTUAL",{"date":43,"type":21},{"date":47,"type":21},"2026-12-01",{"name":49,"class":50},"Regionshospital Nordjylland","OTHER_GOV",1,{"id":53,"slug":54,"hasResults":11,"nctId":55,"briefTitle":56,"officialTitle":57,"acronym":58,"eligibilityCriteria":59,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":60,"enrollmentInfo":61,"targetDuration":4,"studyType":22,"phases":63,"briefSummary":64,"conditions":65,"keywords":68,"overallStatus":79,"whyStopped":4,"lastUpdateSubmitDate":80,"lastUpdatePostDateStruct":81,"startDateStruct":83,"completionDateStruct":85,"leadSponsor":87,"locationsCount":90},"100611187","peripheral-magnetic-stimulation-of-foot-muscles-effects-on-medial-longitudinal-arch-height-and-foot-muscle-strength-in-adults-with-flat-feet-100611187","NCT07237321","Peripheral Magnetic Stimulation of Foot Muscles: Effects on Medial Longitudinal Arch Height and Foot Muscle Strength in Adults With Flat Feet","Peripheral Magnetic Stimulation of Foot Muscles","rPMS-Foot","Inclusion Criteria:\n\n* Age between 18 and 50 years,\n* functionally flat feet of participants.\n\nExclusion Criteria:\n\n* Acute leg injuries,\n* diabetes,\n* vascular disorders of the lower limbs,\n* open wounds or skin lesions on the lower leg or foot,\n* participants with metal implants near the stimulation site,\n* cardiac pacemaker,\n* other orthopedic or neurological conditions that could affect the study results or pose a health risk to the participants.","50 Years",{"count":62,"type":21},30,[24],"This study examines the effects of repetitive peripheral magnetic stimulation (rPMS) on foot invertor muscle strength, morphology, and the height of the medial longitudinal arch (MLA) in individuals with flat feet.

The experimental group will receive rPMS targeting the invertor muscles of the foot, while the control group will not receive stimulation but will follow the same measurement schedule.\n\nAssessments will be performed at baseline, after 6 weeks, and after 12 weeks of intervention. The primary outcome will be the change in the height of the MLA, evaluated using dynamic navicular drop assessment during gait. Secondary outcomes will include changes in the isometric inversion torque of the foot invertors and morphological adaptations of the tibialis posterior muscle assessed by ultrasound imaging.\n\nThis study seeks to determine whether rPMS can improve the height of the MLA, foot invertor muscle strength and structural stability in adults with flat feet.
