Medical Definition for ‘What is Lordosis’ and 3 Lordosis Exercises

The inward curving of a part of the lumber and cervical vertebral column can define what Lordosis is. For an excessive case it is called swayback or saddle back. There are three types of curves that define it which can be present in the human spine1,2:

Scoliotic curves- sideways curvature of the spine; it is always abnormal

Lordotic curves- inward curve of the lumbar spine just above the buttocks

Kyphotic curves- outward curve of the thoracic spine at the level of ribs

For non-severe cases, it can be just a small degree of curve or also called kyphoysis is normally present in the spine. If kyphoysis is too much, it causes round shoulders and is defined as Scheuermann’ disease. If lordotic curving is too much, it is termed as swayback the buttocks more prominent. For small curves, I have given a few Lordosis exercises which are further down in the article.

 What is Lordosis for Children?

Children suffering from too much lordosis will have a space beneath their lower back when lying on their back on a hard surface. When lordotic curve is flexible, it is generally not a concern. When the curve does not move, medical evaluation is needed. Lumber and cervical segments of  the vertebral column are normally lordotic (convexity anteriorly and concavity posteriorly). Anterior pelvic tilt is a major factor of it. Patients with it often show a visible arch in their lower backs. When we look at them from the side, their lower back forms a defined C-shape. Children can also do Lordosis exercises which will help but please get the advise of a doctor before doing anything.

What are the causes of Lordosis?

There are many medical conditions that cause the spine to curve more than normal. These conditions include2,3:

  • Achondroplasia- bones do not grow normally, leading to the short stature.
  • Spondylolisthesis- the vertebrae in the lower back slip forward.
  • Osteoporosis- vertebra become fragile and can easily be broken.
  • Obesity.
  • Kyphoysis
  • Discitis- the inflammation of intervertebral disc
  • Tight lower back muscles
  • Excessive visceral fat
  • Pregnancy
  • Rickets1

What are the symptoms of it?

Symptoms depend upon the severity of the birth defect. It may include:

  • C-shape back when seen from a lateral aspect, with the buttocks being more prominent
  • A large gap between the lower back and the floor when lying on one’s back
  • Pain and discomfort in the lower back
  • Problems in moving in certain ways4

How is it Diagnosed?

It is difficult to measure and diagnose it. The traditional measurement of lumber lordosis is difficult because of the obliteration of the vertebral end plate landmarks by interbody fusion. L4 –L5 and L5- S1 levels are mostly involved in fusion process, and contribute to normal lumber lordosis. It is useful to identify an accurate means of measuring it at these levels1.

Adults with it seem to be sticking out their stomachs and buttocks. During an examination, patients need to lie on his or her back on a hard surface. If the patient can slide his or her hand under their lower back, with a little space to spare they are ok. However, If the patient has it, he or she will have extra space between his or her hand and lower back2,3.

What is Lordosis and its treatments?

Treatment includes:

  • Pain killer medications to relieve the discomfort and back pain
  • Wearing a back brace
  • Weight loss
  • Vitamin D supplementation
  • Surgery
  • Different Lordosis exercises

What are Lordosis exercises?

There are many postural and muscle related factors that contribute to it. These are weak core muscles, tight hip flexors, poor exercise techniques and weak gluteal muscles. Some of these problems may be corrected with lordosis exercises. These include:

Pelvic tilt- pelvic tilt position is a great Lordosis exercise. The position is exactly opposite of the “arched back position”. It can help to correct curved posture if applied daily. The patient must lie on his/ her back with his/her knees bent and feet flat on the floor. Then he/she should inhale properly. After that, he/she should exhale and tilt the lower part of pelvis simultaneously. Twenty repetitions of this Lordosis exercise must be performed daily.


Stability Ball Bridge- this Lordosis exercise strengthens the gluteal muscles. Lie on your back with your calves draped over the ball. Start with a pelvic tilt and the squeeze your butt until a bridge position is obtained. When you roll down, try to feel that each vertebra is touching the floor. Your lower back should touch the floor before your pelvis. Make 12 repetitions daily.

Knees to Chest Stretch and Heel Slide- lie on your back with your knees bent and then lift both legs from the floor and draw the knees to your chest is another great Lordosis exercise. After that, lower one heel to the floor. Keep the opposite knee close to your chest. Rotate the other heel along the floor until the leg is straight. Make 8 repetitions daily5.
