All You Need To Know About Posture
POSTURE DEVELOPMENT
Positional alignment begins its evolution from early life with the development of the spine and its curvature. At first, the spine has a "C "- shaped curve with a convexity and a concavity at birth. Then, as the child attempts to raise his head from the prone lying position, the cervical curve begins to develop and another curve will be developed in the early phase of walking education, which is the lumbar curve. These two curves are known to be the first "secondary curves" called the "main curve."
CURVATURES OF THE SPINE
FRONTAL VIEW: When viewed from the front or back view, the spine appears to be straight and symmetrical.
SAGITTAL VIEW: When viewed from the side of the spine, four normal curves appear which are:
- Two primary curves: the dorsal and the sacral curves which are convex at the back.
- Two secondary curves: cervical and lumbar, which are convex in the foreground.
Types of Postural
Four of the most common postural types that deviate from a good neutral posture are:
Kyphosis Posture
Kyphosis, or hunchback, is an unbalanced posture that can cause neck and back pain. The head is pushed forward, in front of your gravitational center. The upper back is rounded, accentuating the thoracic curve. This condition can develop from unhealthy posture habits, bone and joint degeneration and spinal deformity. Severe cases diagnosed as Scheuermann's kyphosis create a noticeable hump in the upper back.
Lordosis Posture
Everyone's spine curves slightly in the lower back, but people with lordosis have an excessive curve, often with an increased pelvic tilt. The head and stomach are also pushed forward. Often referred back to as hollow or saddle. The posture of lordosis is rising among truck drivers.
Sway Back
A posture of swinging back is where the pelvis is pulled forward, past the center of gravity. A person with a sway back will poke their head forward to compensate for the shift in gravity and their upper back will curve forward. They often sunken their chest, prolonged their shoulders, and have a tight upper abdominal muscle. For pregnant women, obese people who carry the weight for their abdominal area, sway back is most common.
Flat Back
Instead of the natural curves in the spine, the spine’s alignment is flatter than usual for people with a flat back. The pelvis is tucked in, causing people with a flat back posture to stoop forward. Standing for long periods is difficult and they can experience ongoing back and leg pain. Muscle imbalances are often to blame for this posture. Degenerative disk disease and stress fractures may cause flat back syndrome.
