About

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.

Full 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.

Enrollment: 44 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

44 participants in 2 patient groups

Short Foot Exercise + Conventional Physical Therapy

Experimental group

Description:

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.

Treatment:

Behavioral: Short Foot Exercise

Behavioral: Conventional Physical Therapy

Conventional Physical Therapy

Active Comparator group

Description:

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.

Treatment:

Behavioral: Conventional Physical Therapy
