The Effecte of foot orthosis on pattern and electromyographic activity of ankle muscles in collegiate athletes with flat foot during single leg jump landing
The aim of this study was to compare pattern and electromyographic activity of ankle muscles in athletes with flexible flat foot during single leg jump-landing task in two situations with and without foot orthoses. These research design is semi-experimental due to exist intervention variable. The population of 18-23 year-old male students study all athletes are at Tehran University, among these athletes, 15 athletes from the disciplines of volleyball, handball and basketball with flexible flat foot deformity due to the targeting criteria for a sample these were selected. Exclusion criteria from the study of ankle sprains in the past year, lower extremity surgery or lower extremity fractures, ligament or meniscus injuries in the knee, pain in the lower extremities before and during the trial, systemic diseases such as rheumatoid arthritis and diabetes, history of use any type of foot orthoses.

Description
In people with flat foot deformity to correct and support foot arch, rigid or semi-rigid foot orthosis may be recommended. In these study used a semi-rigid prefabricated foot orthoses with medial longitudinal arch that’s inclusive of two harder EVA (Ethylene Vinyl Acetate) layer at below and a surface layer is made of softer leather layer. In addition, this foot orthoses have a metatarsal pad to support foot transverse arch. The benefits of this type of foot orthoses include of durable, affordable and save time (no need for molding) that lead to its widespread use in orthotics clinics. It is generally accepted that the orthotics are effective on the sensory input of foot mechanoreceptors, these effects could increase or decrease their foot sensory feedback.
