The Thomas Test measures hip flexor length and distinguishes tightness between one joint and two joint muscles. Hip flexor length directly correlates to the available range of motion at the hip and knee joints.

The Thomas Test is used in order to assess iliopsoas tightness. Check out our video and test description in order to learn how to perform it!

The Thomas test is used to rule out hip flexor contraction as well as psoas syndrome. Clinically we use this test to help identify factors contributing to hip flexor tightness.

The best test to detect iliopsoas tendinopathy was the HEC test, followed by the resisted hip flexion (seated), SLR in exorotation, and resisted hip external rotation (seated).

The Thomas test is used to evaluate hip flexion contracture and psoas syndrome (Iliopsoas Tightness), which is more common in runners, dancers, and gymnasts with symptoms of hip “stiffness” and …
