liotibial Band Friction Syndrome
is recognized as one of the most common lower-extremity injuries in athletes,
especially in long-distance runners and cyclists.
Casually referred to as runner's knee, this is an inflammatory condition.
Also known simply as iliotibial band (ITB) syndrome, physiologists
debate the actual pathology involved.
While some understand this overuse injury to be associated with
excessive friction between the ITB tract and the lateral femoral epicondyle,
others suspect that ITB syndrome is a consequence
of impaired hip musculature. Whether or not tightened hip muscles
or localized friction are behind ITB syndrome/ There are several
bodywork techniques that can help resolve this problem.
About ITB Syndrome:
ITB syndrome is often observed in those who exercise vigorously.
Upon knee flexion, the ITB moves posteriorly along the lateral femoral epicondyle.
When excessively tight or stressed, the ITB rubs more vigorously
within its groove to generate inflammation.
In runners, friction occurs near or just after foot strike during the
contact phase of the gait cycle. Downhill running reduces
the knee flexion angle and can aggravate ITB syndrome,
while sprinting and fast running increase the knee flexion angle
and are less likely to cause pain.
While the most prevalent symptom of ITB syndrome
is lateral knee pain, other signs may include:
· Hip pain.
· Discomfort, which may radiate from the knee proximally or distally.
· Pain during strenuous activity; however, a case that has progressed
may cause pain with walking.
· A tender point near the lateral femoral epicondyle.
· Pain elicited with active flexion-extension of the knee within the
first 30 degrees, while the thumb presses over the epicondyle and ITB.
ITB Syndrome Causes:
Even though there is little scientific support of ITB syndrome's etiology,
experts agree that it has many possible causes. In addition to an
athletic injury from a change in surface, speed, distance & shoes,
the following are likely to contribute to ITB syndrome:
· Limb length discrepancy
· Bow-leggedness (Genu varum)
· Hip adductor weakness
· Myofascial restriction
