Calf muscle in flat foot

Details and patient eligibility

About

The purpose of the current work is to determine the prevalence of calf muscle tightness in asymptomatic flat foot subjects.

Full description

Pes planus (Flat foot) deformity is a common chronic foot and ankle condition characterized by flattening of the medial longitudinal arch (MLA), rearfoot valgus and abduction of the midfoot on the hind foot.

A flexible pes planus is caused by tibialis posterior dysfunction, ligament loosening, Achilles tendon shortening, and weakness of the intrinsic foot muscles. These deformations cause plantar flexion and adduction of the talus bone and valgus of the calcaneus bone.

Up to our knowledge:

1. No previous studies investigated whether all flat foot is usually associated with gastrocnemius and soleus muscle tightness or it is a random association.
2. And whether tightness of gastrocnemius and soleus is highly found in all cases of flat foot.

Consequently this study is conducted.

Ages: 20 to 40 years old

Volunteers: No Healthy Volunteers
