Neck Rear 'Fatal Package' Movement Rehabilitation

A normal cervical spine has a forward bulge in the lower cervical spine (C3-C7, the lower cervical spine mainly responsible for flexion and extension), and a posterior bulge in the thoracic spine, and the junction between the cervical and thoracic spines is exactly where the forward and posterior bulges meet.

When the lower cervical spine (C3-C7) overextends forward and the upper cervical spine overextends posteriorly, the bony prominence at the bony junction between the cervical and thoracic spines forms; these bony changes are often accompanied by changes in related muscles, forming such a bony bulge, and the related muscle groups become tense and spasm, swelling and bulging; the muscles on both sides of the first and second ribs also bulge, spasm and bulge, and even the flipped ribs can affect the scalene muscles, narrowing the scalene muscle fissure. So what actions will cause the lower cervical spine to overextend forward and the upper thoracic spine to overextend posteriorly?It's when you head forward or tilt your head slightly while tilting your head back! This creates a large bulge at the back of the neck! Posture such as chest raising and back arching further exacerbates the large bulge at the back of the neck!

A normal cervical spine has a 'C' shape, with the cervical spine having a forward bulge, which is its mechanical structural basis.

This 'C' shape of the physiological arc ensures the height flexibility and stability of the cervical spine, and is also the need for human physiology and function.

It is precisely because of the existence of this physiological arc that the seven small bones that make up the cervical spine can bear the weight of the entire head and perform various movements.

Cervical spine curvature is due to the formation of the anterior thickening and posterior thinning of the C4-C5 intervertebral discs, which is also the need for human anatomical structure, and will not cause the intervertebral discs of the cervical spine to protrude.

However, when, for various reasons, the cervical spine becomes straight or the cervical spine becomes hyperflexed, this perfect arc no longer exists. At this time, the cervical spine no longer has the ability to bear the weight of the head, no longer able to buffer pressure, and no longer has the anterior thickening and posterior thinning of the C4 and C5 intervertebral discs, so the cervical spine will undergo degenerative changes, intervertebral discs will protrude, causing pain, dizziness, numbness, etc.
