Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Short Foot Exercise + Conventional Physical Therapy

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.

Group Type EXPERIMENTAL

Short Foot Exercise

Intervention Type BEHAVIORAL

* 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.

Conventional Physical Therapy

Intervention Type BEHAVIORAL

* 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.

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.

Group Type ACTIVE_COMPARATOR

Conventional Physical Therapy

Intervention Type BEHAVIORAL

* 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.
