Clinical Trial: The Effect of a Six-Week Corrective Exercise Program on Plantar Pressure Distribution and Dynamic Balance in Young Male Soccer Players with Flexible Pes Planus (Japan)

Tokyo, June 16 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000061739) titled 'The Effect of a Six-Week Corrective Exercise Program on Plantar Pressure Distribution and Dynamic Balance in Young Male Soccer Players with Flexible Pes Planus' on June 16.

Study Type: Interventional

Study Design: Basic Design - Parallel Randomization - Randomized Blinding - Single blind -investigator(s) and assessor(s) are blinded Control - Active

Primary Sponsor: Institute - self funding

Condition: Condition - pre-post Classification by malignancy - Malignancy Genomic information - NO

Objective: Narrative objectives1 - This study is a two-arm, parallel-group, randomized controlled trial designed to evaluate the effect of a six-week corrective exercise program on plantar pressure distribution and dynamic balance in young male soccer players with flexible flatfoot. Participants (n=40) aged 10 to 15 years were randomly assigned to either a corrective exercise group (n=20) or a control group (n=20). The primary outcomes are peak plantar pressure (kPa) in the forefoot and heel regions and the Center of Pressure Excursion Index (CPEI). The secondary outcome is dynamic balance measured by the Y Balance Test composite score. All outcomes were assessed at baseline and immediately post-intervention (6 weeks). Basic objectives2 - Efficacy

Intervention: Interventions/Control_1 - Participants in the experimental group performed a six week corrective exercise program Interventions/Control_2 - Participants in the control group

Eligibility: Age-lower limit - 10 years-old = Gender - Male Key inclusion criteria - Male sex Age 10 to 15 years Active participation in a football club or school team for at least two years, with a minimum of three training sessions per week Confirmed flexible flatfoot based on both. Key exclusion criteria - Presence of systemic or neuromuscular disorders (cerebral palsy, spina bifida, peripheral neuropathy, vestibular disorders, rheumatoid arthritis, lupus, diabetes mellitus) History of severe lower extremity injury within the past year (fracture) or within the past two years (anterior cruciate ligament rupture, meniscus tear, ankle dislocation) Obvious lower limb deformities such as cavus foot, knee varus valgus (abnormal Q angle), or leg length discrepancy greater than cm confirmed by an orthopedic specialist Limited ankle dorsiflexion range of motion (less than with knee fully extended). Target Size - 42

Recruitment Status: Recruitment status - Preinitiation Date of protocol fixation - 2026 Year 04 Month 03 Day Date of IRB - 2026 Year 04 Month 01 Day Anticipated trial start date - 2026 Year 05 Month 01 Day Last follow-up date - 2026 Year 06 Month 13 Day
