The patient, already lying prone, places the elbows under the shoulders and raises the top half of his body so that he comes to lean on elbows and forearms while pelvis and thighs remain on the couch. In this position the lumbar lordosis is automatically increased. Emphasis must be placed on allowing the low back to sag and the lordosis to increase.

Procedure 2 is a progression of procedure 1 and merely enhances its effects by increasing extension.
Again, in derangement some time must be allowed to affect the contents of the disc and, if possible patients should remain in this position for five to ten minutes. In more acute patients sustained extension may not be well tolerated due to pain, and initially we must rely on the use of intermittent extension.
