What is fascia?

The IT-Band is a thick band of fascia. We don't usually know about the iliotibial band until it causes a problem.

Fascia (or myofascia) is a network of connecting fibers beneath the skin. It is not muscle and, it is indeed, a body system by itself. It has several purposes: it can attach, stabilize, enclose or separate muscles and internal organs. It looks a little like a very densely woven spider's web. From the top of your head to the tip of your toes, fascia aides you with flexibility, strength and stability. Fascia is very strong and very flexible. In fact, it has a tensile strength of over 2000 pounds. 2

There are three types of fascia:

What can go wrong with fascia?

Most of the time, we are unaware of fascia, but it becomes noticeable to us when it loses stiffness or becomes too stiff. This can happen after surgery if the fascia has been cut or when healing includes a scar. It also can be felt due to a repetitive movement. As with muscles, it can be pulled and strained. 3

There are several conditions that are injured fascia:

The pain for ITBS occurs near the knee.

In humans, the Iliotibial band (often referred to as the IT band) extends from the iliac crest in the pelvis to the tibia near the outside of the knee. Both the tensor fascia lata and the gluteus maximus insert into the IT band.

The band is particularly important during running or walking where it helps to stabilize the knee; it moves from behind the femur to the front of the femur during activity.

When the knee is flexed, the IT band is located behind a bony outcropping of the femur at the knee joint (known as the femoral epicondyle). The IT band moves forward across the condyle when the knee is extended. There is a sac that allows the band to glide smoothly across the condyle, but if inflammation occurs in this area, the increased friction from repeatedly rubbing the iliotibial band across the bony condyle can cause pain, especially along the outside of the knee joint.

Can Fascial Injuries Be Treated?

There are treatments recommended for fascial injuries, but the science for some of them is limited. However, if symptoms are ignored, inflammation may continue and scarring could possibly develop — this in turn could decrease range of motion (if a joint is involved) and increase pain. Activity could be impeded even while healing takes place.

The first line of defense is always rest, as fascial injuries are usually overuse injuries. Using ice may also help. There are many other possible treatments — see your doctor or healthcare provider or check out the many articles on the internet. Since this is not my area of expertise, I will leave treatment options up to the reader. Be aware that some types of treatment are controversial. I recommend, whenever possible, that you choose science-based and well-researched alternatives.

  2. Can you stretch fascia? This is the subject of much debate. Some say yes. Some say no. You will find arguments for both on the internet, but if one is looking for sound information, one should focus on science-based results.
