Test protocol – "Waiters bow". Flexion of the hips in upright standing without movement (flexion) of the low back. A. Correct - Forward bending of the hips without movement of the low back (50–70° Flexion hips). B Not correct Angle hip Fx without low back movement less than 50° or Flexion occurring in the low back. Rating protocol: As patients did not know the tests, only clear movement dysfunction was rated as "not correct". If the movement control improved by instruction and correction, it was considered that it did not infer a relevant movement dysfunction.
