Research

In my research this afternoon I just read an amazing article that taught me something new: During the modified Thomas Test, if there is abduction of unresisted leg, that two possible probabilities are a reduced lengthening (tightness) of the TFL and Sartorius.

This makes sense to me as the Sartorius is a muscle built as a synergist and would be called into play should the primary agonists of hip flexion shut down or be called into over-time. The TFL joins the Gluteus Maximus to form the IT band - it's attachment to the Tibia easily can cause abduction

Good times.
