Conduct this assessment to determine muscular endurance of the Anterior Core.
Beginning on all fours, the client is asked to raise the knees into a plank position and hold with the back flat for 60 seconds.
Watch for arching or dipping of the pelvis while asking the client where they "feel" this exercise.
Improper pelvic position indicates poor muscular endurance while pain or sensation in regions other than the abs indicates an inability to consciously brace.
Stop the test if there are any irregularities or pain and record the time to compensation.
