Tightness of the iliotibial band or lateral hip structures can be assessed by observing leg hang during the modified Thomas test.

“it's called the modified Thomas test and I'm going try just let your leg hang down comfortably and a couple of things here I'm looking at the angle between his thigh and the table and if I push down what I'm really assessing is how tight are the um the hip flexor muscles in particular the ilos sois so he's a little bit elevated from neutral some people go all the way down again depending on what the particular complaint is there may be stiffness because of arthritis it may be stiffness because of um a tightness of the flexor muscles or it might be loose because of instability and the other motion I'm checking here is to see the ilot tibial band so some people are easily go towards midline some people pop back and so this may indicate some tightness of the structures on the lateral aspect of the hip and then I'll compare the other one so you bring your knee to this side and let this hang so your ilot bands are probably be a little bit tighter not much and see if and also I'm checking to see can you just let your leg hang that's about it so that will give us indication of some quad tightness too and also to see how much the hip is elevated compared to the table okay so we got more to do so now we move to the lateral position where I have you get lie onto your left side and so I get a first thing I do is I check the spine I want to make sure that that doesn't hurt I check the SI joint to see if that generates any pain this is where I'll check where the Sartorius originates from and the tensor muscle as well um and and again here's be another opportunity to check your abductor train so I'll have Peter lift up your leg and don't let me push down good and that's it's a it's a more sensitive test in the sense if you really have an abductor problem this is hard to do and this relax your leg completely um so before we were looking at it IT band tightness or tightness on the on the lateral aspect of the hip and I want to see if Peter's knee can come all the way down to the table and that's good good so he's pretty good there um and also this is an opportunity we can check to see if there's any instability um just like the shoulder we sort of do this provocative maneuver where I'm pushing on the greater troter to see if I could push the ball forward and”

“and also to see how much the hip is elevated compared to the table”

“and the other motion I'm checking here is to see the iliotibial band so some people are easily go towards midline some people pop back and so this may indicate some tightness of the structures on the lateral aspect of the hip”
