Question: The function of the Psoas is often considered as a possible contributor to lumbar pain. To asses a Psoas that may be restricted, hypertoned, and shortened perform all but the following:
a. The Thomas Test b. Measure External Hip Rotation
c. Measure Internal Hip Rotation d. Muscle test Hip Flexion for painful response
The answer is b. The function of the Psoas is hip flexion and external rotation. The Thomas test gives us information on whether hip extension is limited and if that movement causes discomfort or pain, thereby noting the hypertoned Psoas as a hip flexor is painful when elongated and is limiting hip extension. If we measure internal hip rotation as limited, it points to the hypertoned Psoas as hip external rotator as tight and restricted. If we muscle test hip flexion and it is painful, it suggests putting a load on the Psoas as hip flexor may have compromised function.
