Kraus Weber Postural Muscles Test, Part 2
To test the strength of the hip flexors have your subject lie on their back and raise both straightened legs about eight inches off the floor using your hand to approximate the eight inches for them. Have them hold it for a ten second count. (One and two and three…) Watch their low back to see if it arches and creates a space. If there is an extreme arch then corrective exercises will be in order.
Continue with the next test.
