Table 1 Movement tests for classifying the lumbar extension rotation syndrome

Position	Test items	Test responses with increased low back pain
Standing	Alignment	Increased lumbar extensionIncreased anterior pelvic tilt with hip flexion Asymmetrical paraspinal hypertrophy
	Return from forward bending	Initiated movement with lumbar extension
	Side bending	Increased lumbar rotation
Supine	Active hip and knee flexion-unilateral	Increased lumbar rotation with pelvic rotation
	Hip external rotation/abduction in hook lying	Increased lumbar rotation with pelvic rotation
Sidelying	Alignment	Increased lumbar extension and lateral bending/rotation
Prone	Alignment	Increased lumbar extension
	Active knee flexion-unilateral	Increased lumbar extension with anterior pelvic tiltIncreased lumbar rotation with pelvic rotation
Quadruped	Alignment	Flat lumbar spineAsymmetrical paraspinal hypertrophy
	Rock backward	Increased lumbar rotation
	Rock forward	Increased lumbar extension
