To Effectively Apply a Manipulation Technique to Improve Cervical Flexion

To effectively apply a manipulation technique to improve cervical flexion, you would:

A) Position the patient supine with knees flexed and her arms at her side and use a two-thumb contact on the spinous process while pressing in a caudal direction.
B) Stand on one side of the patient with your body facing caudally and contact the cervical pillar on that side with the second metacarpal phalangeal joint and apply a caudally directed force.
C) Position the patient prone and use a two-thumb contact on the transverse processes of the superior restricted segment of the three-joint complex and apply a caudally directed force.
D) Position the patient prone and apply force through the thumbs to slide the superior vertebra in a cephalad-anterior direction.
