What is Lordosis?

·          Note 1: Lordosis is also referred to as 'swayback'

·          Note 2: The term 'lordosis' is generally used to describe excessive inward curve of the spine. The term 'normal lordosis'is generally used to describe a normal inward curve.

"Lordosis is a disorder defined by an excessive inward curve of the spine." Lordosis



Back Pain, Poor Movement

·          "Too much of a curve in the low back puts pressure on the entire back. This can lead to pain and poor movement.

·          Good posture is necessary to keep the curves in their proper positions. Strong, flexible muscles help maintain these curves.

·          Weak and stretched out muscles cannot give our spine adequate support for good posture.

·          Practice good posture while standing and especially while sitting."

Weak Glutes

·           Posture: Weak Glutes



·          "When sitting, keep your feet flat on the floor. Adjust your chair, or add a small wedge to sit on so your hips are slightly higher than your knees. Support the lower curve in your back with a pillow. Too much or too little of a curve can cause problems.

·          When standing, rest one leg higher on a step to help support the low back.

·          Do not lock your knees straight when standing.

·          If you sleep on your stomach, place a flat pillow under your belly. It is better to sleep on your back with a pillow under your knees.

·          Wear shoes that provide good support. If the heels of your shoes are too high, your posture will tend to fail.

·          Keep your belly (abdominal) and buttock muscles strong and firm. These are the most important low back muscles."

"Obesity may cause some overweight people to lean backward to improve balance. This has a negative impact on posture." Lordosis


Things to Avoid

Lumbar Supports, Increases in the Seat Angle

Note: ‘Increases in the seat angle’ means that the angle between the back of the chair and the seat pan of the chair is greater than 90°

“The influence of backrest inclination and lumbar support on the shape of the lumbar spine in sitting positions has been studied radiographically on 38 healthy subjects. Four angles of backrest inclination and four different sizes of lumbar support were studied. In addition, the lumbar support was placed at three different lumbar levels.

·        When sitting down from a standing position, the pelvis rotates and the lumbar lordosis decreases [positive effect].

·        Increases in the backrest-seat angle had only minor effect [negative effect] on the lumbar lordosis.

·        A lumbar support, on the other hand, had a significant influence: the lordosis increased with increasing support [negative effect].

The location of the lumbar support with respect to the level of the spine did not significantly influence the measured angles.”
