The Cranio cervical flexion exercise will be performed with the patient in supine crook lying with the neck in a neutral position (no pillow) such that the line of the face is horizontal and a line bisecting the neck longitudinally is horizontal to the testing surface. The uninflated pressure sensor will be placed behind the neck so that it abutted the occiput and is inflated to a stable baseline pressure of 20 mm Hg, a standard pressure sufficient to fill the space between the testing surface and the neck but not push the neck into a lordosis. the patient attempted to sequentially target five, 2-mm Hg progressive pressure increases from the baseline of 20 mm Hg to a maximum of 30 mm Hg as well as to maintain a isometric contraction at the progressive pressures as an endurance task.

The CVA was formed at the intersection of the horizontal line, which passed through the back and the line, which joined the tragus of the ear and the back. The Patient Will Be In Standing Position and the image will be taken from the lateral view then the image will be inserted to IMAGEJ Software To Measure The Angle

The the patient in supine crook lying with the neck in a neutral position. The uninflated pressure sensor will be placed behind the neck so that it abutted the occiput and is inflated to a stable baseline pressure of 20 mm Hg.The movement will perform gently and slowly as a head nodding action (as if saying "yes"). The Cranio cervical flexion exercise the activation and endurance of the deep cervical flexors in progressive inner range positions as the patient attempted to sequentially target five, 2-mm Hg progressive pressure increases from the baseline of 20 mm Hg to a maximum of 30 mm Hg as well as to maintain a isometric contraction at the progressive pressures as an endurance task.
