Standing at the long edge of the bench on the side to be examined/treated
Position of the patient:
Prone lying position
Hand placement:
Fixating hand on L4 with a pinch grip in ventrocaudal direction
Contralateral leg grabbed with the other hand above the knee joint from the inside, moving the hip into its maximally closed packed position of internal rotation, adduction and extension
Movement:
Homonymous 3D movement with equal components of extension, ipsilateral lateral flexion and ipsilateral rotation by bringing the hip further into extension and adduction until the fixating hand wants to move
In order to test each component of intervertebral motion, slightly move out of the end-range and now test extension between L4 and L5 by pushing the spinous process of L4 ventrocaudally
To assess the rotation component, move to the contralateral arch of L4 and push it ventrally
For the lateral flexion component, put the thumb between the spinous processes of L4 and L5 and perform lateral flexion by moving the hip further into adduction
