The Iliotibial (IT) band is a thick, fibrous band of tissue that extends from the hip to the outside of the knee and performs as a stabilizer of these two joints. If the buttock muscles are under-trained, the IT band and its adjoining muscle will become overactive during repetitive motions like running and cycling. The IT band interfaces with the quadriceps and hamstrings and should glide smoothly over these muscles during walking and running gait. If pressure and friction occurs between these tissue, scarring will develop over the region.
Active Release Technique attempts to break down these adhesions (scar tissue) to allow for a smooth gliding action of the IT band on the adjacent musculature. It is also very important to functionally assess the foot in addition to the hip and knee as excessive pronation of the foot can be a major contributing factor to this condition.
