Effect of Lumbar Manipulation on Intervertebral Motion, Pain, and Disability

"The participant lies on the right side. The right leg is straightened at the knee. The left knee is flexed to the level to be manipulated, and the left foot is placed behind the right lower leg. The caregiver introduces rotation of the participant's upper body down to the level to be manipulated. The caregiver then takes up an axillary hold. The caregiver places his right forearm in the region between the gluteus medius and maximus. The caregiver then rolls the participant towards them. Prior to thrusting, the caregiver applies a slight overpressure and holds the position for 10 seconds. If the participant does not experience any adverse effects, over-pressure is released, and the restrictive barrier re=engaged. The caregiver applies a HVLA thrust against the participant's buttocks by dropping their body. If a cavitation pop is not heard the first time, a second attempt is made. The procedure is repeated on the opposite side."

The caregiver applies a HVLA thrust against the participant's buttocks by dropping their body. NO ROTATION OCCURS IN THE SPINE. The procedure is repeated on the opposite side.
