This article is about the human spinal shape and disorders thereof. As such, lordosis in the human spine is considered one of the primary physiological adaptations of the human skeleton that allows for human gait to be as energetically efficient as it is. These conditions are usually a result of poor posture and can lumbar stenosis exercises pdf be reversed by learning correct posture and using appropriate exercises. Lordosis may also increase at puberty, sometimes not becoming evident until the early or mid-20s.
X-ray taken of a patient leaning backward. Lumbar hyperlordosis is a common postural position where the natural curve of the lumbar region of the back is slightly or dramatically accentuated. Commonly known as swayback, it is common in dancers. Other health conditions and disorders can cause hyperlordosis. The most problematic symptom is that of herniated disc where the dancer has put so much strain on their back that the discs between the vertebrae have been damaged or have ruptured. Tightness of the iliopsoas results in a dancer having difficulty lifting their leg into high positions.
The most obvious signs of lumbar hyperlordosis is lower back pain in dancing and pedestrian activities as well as having the appearance of a swayed back. Natural factors of how spines are formed greatly increase certain individuals’ likelihood to experience a strain or sprain in their back or neck. Another odd body formation is when an individual has a leg shorter than the other, which can be immediate cause for imbalance of hips then putting strain on the posture of the back which an individual has to adjust into vulnerable positions to meet aesthetic appearances. This can lead to permanent damage in the back. This causes great stress and risk of injury, especially because the dancer will have to compensate to obtain the positions required. One of the greatest contributors is uneven muscles.
Because all muscles have a muscle that works in opposition to it, it is imperative that to keep all muscles protected, the opposite muscle is not stronger than the muscle at risk. The muscular imbalance results in pulling down the pelvis in the front of the body, creating the swayback in the spine. Younger dancers are more at risk for development of lumbar hyperlordosis because the lumbar fascia and hamstrings tighten when a child starts to experience a growth spurt into adolescence. This can be attributed to the strains of repetitive dance training may lead to minor trauma. If the damaged site is not given time to heal the damage of the injury will increase.
Abrupt increases in dance intensity or sudden changes in dance choreography do not allow the body to adapt to the new stresses. New styles of dance, returning to dance, or increasing dance time by a great deal will result in exhaustion of the body. Measurement and diagnosis of lumbar hyperlordosis can be difficult. Obliteration of vertebral end-plate landmarks by interbody fusion may make the traditional measurement of segmental lumbar lordosis more difficult. Because the L4-L5 and L5-S1 levels are most commonly involved in fusion procedures, or arthrodesis, and contribute to normal lumbar lordosis, it is helpful to identify a reproducible and accurate means of measuring segmental lordosis at these levels. A visible sign of hyperlordosis is an abnormally large arch of the lower back and the person appears to be puffing out his or her stomach and buttocks.
