What is Extensor Digitorum Brevis Muscle and What is Its Function?

The very top of the foot has what is called as the Extensor Digitorum Brevis Muscle. This muscle is connected to the tendons which are attached to the toes. This muscle is innervated by the deep fibular nerve. The main function of the Extensor Digitorum Brevis Muscle is to control the movement of the toes. This muscle spares the smallest toe from its control. Extensor digitorum brevis pain can occur due to injury or trauma to the muscle and can result in medical conditions like dropfoot or interosseus syndrome. These medical conditions cause a lot of difficulty for the affected individual to move the toes comfortably. A strain or injury to the extensor digitorum brevis muscle can cause severe pain in the top of the foot and make it difficult for the individual to walk normally. Extensor digitorum brevis pain can occur in athletes who run cross country and participate in full marathons as they have to run on uneven terrains and thus putting pressure on the top of the foot and hence injuring the extensor digitorum brevis muscle. The basic mode of treatment for extensor digitorum brevis pain is physical therapy, exercises, cold therapy, and foot supports.
