The patient lies prone as for procedure 1. The therapist stands to one side of the patient and, having selected the correct segment, places the hands on either side of the spine as for the technique of rotation mobilisation in extension (procedure 9), which is always applied as a premanipulative testing procedure.
The information obtained from the mobilisation is vital and determines on which side and in which direction the manipulation is to be performed. If following testing the manipulation is indicated, the therapist reinforces the one hand with the other on the appropriate transverse process. The manipulation is then performed as in procedure 8.

The effects of the external force and the reasons for its use are the same as for procedure 9. When the desired result is not obtained with the mobilising technique, manipulation is indicated under certain circumstances. Regarding the direction in which the manipulation is to be performed the same rules apply as for procedure 9.
