Iliotibial band syndrome - Symptoms, Cause, Treatment and Prevention
Wednesday, May 20th, 2009Are you having knee problems? Knee pain is one of the most common injuries in runners and cyclists. The IT syndrome or Iliotibial band friction syndrome as it is also called, is the most common knee problem. IT-Band syndrome causes a diffuse pain in the knee and sometimes also a painful, sharp localized discomfort nearby the knee joint.
The tough tissue band running along the knee bone, from the hip to the shinbone, called IT band was until recently rubbing against the thigh bone, nearby the knee joint, according to researchers. Flexing and extending the leg would cause this rubbing phenomena and that would cause friction. The friction would make the Iliotibial band sore and this soreness was the cause of the pain.
Today the researcher know, that the IT band is not rubbing at all (Fairclough et al.). The cause for the pain is pressure from the Iliotibial band on a fatty tissue, placed between the Iliotibial band and the knee joint. This tissue consists of a lot of nerves, which when stressed will give a feeling of pain. Flexuring and extending the leg build up the pressure on the fatty tissue.
With this new understanding of the biomechanics of the Iliotibial band syndrome it has become clear that to reduce the tension on the Iliotibial band you have to reduce the tension in the muscles connecting to it. That is primarily the gluteus maximus, the biggest muscle of the buttocks, and the tensor fasciae latae which is a muscle of the thigh.
You can reduce the tension through stretching and strengthening them. The stretching exercises I proposed in my last post 8 Yoga poses for removing or preventing knee pain (IT band) could help you with that.
Typical symptoms of Iliotibial band syndrome are:
* Pain just above the knee joint
* Swelling or thickening of the IT band over the lateral femoral epicondyle
* Pain at the hip
* Diffuse pain in knee area
* Sharp localized pain at the lateral femoral epicondyle
* Clicking - as if the IT band tightens and snaps across the joint
Typical causes for Iliotibial band syndrome are:
* Increasing distance in training too fast
* Running downhill
* Cycling with the feet in an excessive angle
* Running on a crowned surface
* Uneven leg length
* Bowlegs
* Weak hip abductor muscles
Typical treatment of Iliotibial band syndrome are:
* Putting ice on the sore spot
* Stretching
* Massage
* Rest
* Hip abductor strengthening
For those of you who havent got a problem with the IT band, the following methods could help preventing it:
* Stretching
* Strengthening of hamstrings, quadriceps, calf muscles and hip abductors
* Slowly increasing training volume
* No downhill running
* Rest
* Shorten your stride
* Using a correct sit position on the bike
