Do you have any heel or sole pain at the first step after waking up or after walking for a long distance? If so, you might have plantar fasciitis. Plantar fasciitis is an inflammatory response within the plantar fascia. It is one of the most common causes of the heel pain. A wide range of population from high level athletes to sedentary workers suffer from heel pain caused by plantar fasciitis. In this blog, I would like to introduce the recent evidence and the general treatment plans for the plantar fasciitis.<\/p>\n<\/div>\n\n\n\n

What is plantar fascia?<\/h1>\n\n\n\n

Plantar fascia is a thick and strong fascial structure found in the superficial surface of the sole under the skin. This structure is not a tendon nor muscle, but it plays an important role in walking\/running for a shock absorption and a force production with its own stretching and shortening capacity. It covers a whole foot from the heel to the base of the toes, then it emerges into the tendons of the toes. Plantar fascia gets taut when you bring your toes up, and it gets slack when you point your toes down. During walking, tension of the plantar fascia helps to enhance the whole foot stability while putting our weight on our feet.<\/p>\n<\/div>\n\n\n\n

Plantar fascia has no function to change its length by itself. In other word, other muscles and joint motions are necessary to change tension of the plantar fascia. Deeper to the plantar fascia, a lot of muscles within the foot attach to it. A part of the Achilles tendon also reaches to the plantar fascia through the sheath superficial to the heel bone (interesting!!). These structural connections are the hints of the treatment options for plantar fasciitis (i.g., stretching calf muscles or foot muscle strengthening).<\/p>\n<\/div>\n<\/div>\n\n\n\n
