This study seems to show a relationship between iliotibial band (ITB) syndrome and knee adduction (genu varum) and the activation of the TFL. A relationship can be two incidents that occur together, termed a “coincidence.” Or there can be a causal relationship between them; i.e., one causes the other to occur.
There is a Third “Deep Layer” of the Iliotibial Band (ITB)
It is not generally known that the iliotibial band (ITB) actually has three layers: a superficial, intermediate, and deep layer.
Can the Iliotibial Band (ITB) be stretched?
There seems to be a belief that the iliotibial band (ITB) cannot be stretched and thus manual treatment on the ITB is futile.
