Official title
The Effects of Short Foot Exercises on Knee Muscle Tone, Knee Pain and Function, Balance, and Quality of Life in Patients with Flexible Flat Foot with Knee Pain
Overview
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.
Detailed description
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.
Interventions
- Behavioral Short Foot Exercise
* 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 p - Behavioral Conventional Physical Therapy
* 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
