An interventional study of Short Foot Exercise and Conventional Physical Therapy in Flexible Flatfoot, Knee Pain and Balance Impairment, sponsored by Sahmyook University. Not yet recruiting at 1 site in Korea, Republic of. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2025-03-06.

This study was a clinical trial to investigate the effects of Short Foot Exercise (SFE) and standard physical therapy on knee muscle tone, knee pain and function, balance ability, and quality of life in adults with flexible flat feet and knee pain.
This study aims to determine whether strengthening foot intrinsic muscles through SFE can reduce knee pain, improve muscle function, enhance balance, and improve quality of life in individuals with flexible flatfoot. Results may provide evidence-based rehabilitation strategies for managing knee pain in these patients.
173 studies on the registry are indexed under Flatfoot; 44 are open to participants now.
This study's planned enrollment of 44 is close to the median of 40 across 122 interventional studies indexed under Flatfoot.

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Participants in this group will receive Short Foot Exercise (SFE) combined with Conventional Physical Therapy for four weeks. This intervention combination aims to determine whether Short Foot Exercise, in addition to conventional physical therapy, provides greater improvements in knee pain, muscle tone, balance, and quality of life compared to physical therapy alone.
Behavioral: Short Foot Exercise · Behavioral: Conventional Physical Therapy
Participants in this group will receive Conventional Physical Therapy only for four weeks. This control group serves as a baseline comparator, allowing researchers to assess whether adding Short Foot Exercise to conventional therapy provides additional benefits for knee pain, muscle function, balance, and quality of life.
Behavioral: Conventional Physical Therapy
* Description: Short Foot Exercise is a therapeutic exercise designed to strengthen intrinsic foot muscles and improve medial longitudinal arch stability. * Procedure: Participants will perform Short Foot Exercise twice daily, five times per week for four weeks. The exercise consists of progressive phases, starting with basic foot activation and advancing to resistance-based strengthening using bands. * Purpose: To determine if strengthening the foot's intrinsic muscles positively impacts knee pain, muscle function, and balance in individuals with flexible flatfoot.
* Description: Standard non-invasive physical therapy aimed at reducing knee pain, improving muscle relaxation, and enhancing lower limb function. * Procedure: Participants will receive twice-weekly conventional physical therapy for ten minutes per session over four weeks. Treatment includes soft tissue mobilization, muscle relaxation techniques, and neuromuscular stimulation, as appropriate for knee pain relief. * Purpose: To evaluate its effectiveness as a standalone treatment compared to the addition of Short Foot Exercise.
Change in Knee Muscle Tension from Baseline to 4 Weeks (Measured by Myoton Pro - Frequency in Hz)
* Description: This outcome measure assesses changes in muscle tension (tone) in the knee region before and after the intervention. * Measurement Tool: Myoton Pro * Unit of Measure: Frequency (Hz) * Assessment Method: Myoton Pro applies a gentle mechanical impulse to the skin overlying the Vastus Medialis, Biceps Femoris, Gastrocnemius Medialis, and Tibialis Anterior muscles, recording oscillation frequency as an indicator of muscle tone.
Time frame: From enrollment to the end of treatment at 4 weeks
Change in Knee Muscle Stiffness from Baseline to 4 Weeks (Measured by Myoton Pro - Stiffness in N/m)
* Description: This measure evaluates changes in muscle stiffness, reflecting muscle resistance to external force. * Measurement Tool: Myoton Pro * Unit of Measure: Newton per meter (N/m) * Assessment Method: Stiffness is quantified by Myoton Pro by applying a controlled impulse and measuring the muscle's resistance to deformation.
Time frame: From enrollment to the end of treatment at 4 weeks
Change in Knee Muscle Elasticity from Baseline to 4 Weeks (Measured by Myoton Pro - Logarithmic Decrement)
* Description: This measure evaluates changes in muscle elasticity, which indicates the muscle's ability to return to its original shape after deformation. * Measurement Tool: Myoton Pro * Unit of Measure: Logarithmic decrement * Assessment Method: The Myoton Pro records how quickly oscillations in the muscle dampen after a mechanical impulse, representing its elasticity.
Time frame: From enrollment to the end of treatment at 4 weeks
Change in Dynamic Balance from Baseline to 4 Weeks (Measured by Y-Balance Test - Reach Distance in cm)
* Description: This measure assesses changes in lower limb balance and stability using the Y-Balance Test (YBT). * Measurement Tool: Y-Balance Test (YBT) * Unit of Measure: Reach distance (cm) * Assessment Method: Participants will perform three reach directions (anterior, posteromedial, posterolateral) while maintaining single-leg stance. The maximum reach distance for each direction is recorded and averaged.
Time frame: From enrollment to the end of treatment at 4 weeks
Change in Quality of Life from Baseline to 4 Weeks (Measured by EQ-5D-5L - Score on a 5-Dimension Scale)
* Description: This outcome measure evaluates self-reported quality of life in five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. * Measurement Tool: EQ-5D-5L * Unit of Measure: Score on a 5-Dimension Scale * Assessment Method: Participants rate their health status on a 5-level Likert scale (1 = No problems, 5 = Extreme problems). A total EQ-5D-5L index score is calculated using a weighted algorithm.
Time frame: From enrollment to the end of treatment at 4 weeks
Change in Knee Pain from Baseline to 4 Weeks (Measured by WOMAC Pain Subscale - Score on a 5-Point Likert Scale)
* Description: This measure evaluates knee pain severity before and after treatment. * Measurement Tool: Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) - Pain Subscale * Unit of Measure: Score on a 5-Point Likert Scale * Assessment Method: Participants rate pain intensity across five activities (e.g., walking, climbing stairs) using a 0-4 scale (0 = No pain, 4 = Extreme pain).
Time frame: From enrollment to the end of treatment at 4 weeks
Change in Knee Function from Baseline to 4 Weeks (Measured by WOMAC Function Subscale - Score on a 5-Point Likert Scale)
* Description: This measure assesses changes in functional ability and movement limitations. * Measurement Tool: WOMAC - Function Subscale * Unit of Measure: Score on a 5-Point Likert Scale * Assessment Method: Participants rate functional difficulty in 17 daily activities (e.g., rising from a chair, bending) on a 0-4 scale (0 = No difficulty, 4 = Extreme difficulty).
Time frame: From enrollment to the end of treatment at 4 weeks

Start is estimated for Mar 2025; primary completion for Apr 2025, 1 month later.
Of 89 non-industry interventional studies with no phase under Flatfoot, half reached primary completion within 7 months of starting (the median), counting those still running; a quarter within 2 and three quarters within 15. This study's planned 1 month is below that.
Counting every sponsor, half of 89 studies reached it within 7 months; a quarter within 2 and three quarters within 15.
