During assessment, the aim of PAIVM is to reproduce patient symptoms, and assess the endfeel of cervical<unk>  quality of resistance, behaviour of pain throughout the range of<unk>  and observe any muscle spasm. A posterior to anterior force of varying strength is applied by the therapist either centrally onto the spinous process, or unilaterally on either the left or right articular pillar. As a treatment technique, pain is treated by oscillations of small amplitude short of resistance, whilst stiffness is treated by larger amplitudes 50% into resistance. Contraindications The technique is contraindicated by bone disease, malignancy, pregnancy, vertebral artery insufficiency, active ankylosing spondylitis, rheumatoid arthritis, spinal instability, acute irritation or compression of the nerve root, and recent whiplash.
