Lordosis

The lordosis ( " bent forward" from the Greek λορδός ( lordos ) ) is a convex curvature of the spine to the front ( ventral). The curvature of the rear ( posterior to ) is referred to as kyphosis.

In humans, a lordosis in the cervical spine ( cervical ) and lower back ( lumbar ) normal ( " physiological" ). The figure shows a normal spinal posture with kyphosis about in middle and below the lumbar lordosis.

Swayback or hyperlordosis

As a swayback or hyperlordosis a poor posture is called with exaggerated lordosis of the lumbar spine, in which the abdominal wall to bulge through the displacement of the pelvis forward. In order not to fall forward, the chest is behind the body axis shifted ( kyphosis ). The abdominal muscles prevents tipping backwards by being tense permanently in the stretch. Timer can on the one deficient coached by lack of exercise or incorrect posture, shortened back muscles hypertonic be that inhibits the function of the abdominal muscles as an opponent, by not relaxed. In addition, a hypertonic and thus non-renewable back muscles, which compresses the spine and the posterior portions of the vertebral segments on one side, be a reason for herniated discs, spinal stenosis and slipped vertebra. In advanced stages, can cause back pain a hollow back. To improve this poor posture back exercises, relaxation techniques, breathing techniques and manual physiotherapy techniques for detonification the back muscles can be used.

In pygmies and some other West African ethnic groups, there is a strong genetic hollow back, which is not pathological but, in this case.
