Scoliosis

 

The term "scoliosis" refers to the lateral inclination of the spine. Causes are not known, it is thought that most scoliosis are determined by alterations of trunk, limbs, neck and head.

 

Generally, the functional scoliosis is discovered during adolescence, can worsen with growth and may cause difficulty in movement, breathing, activity of our internal organs. Idiopathic scoliosis instead is a deforming disease of the spine and develops until we reach bone maturity: it seems to be hereditary, linked to genetic and metabolic disorders. It occurs in young population with a frequency between 1 and 2% while in people older than 50 years the frequency is around 6%

 

"scoliotic" posture

- Tilted head
- Eyes, nose and chin oriented toward the longer part of the body
- Rigid back
- Asymmetrical back
- Chest with scoliotic column deflected laterally
- Unbalanced pelvis with iliac crest placed at different levels
- Abdominal and dorsal muscles unbalanced due to the verticalisation of vertebrae
- Ttense and shortened muscles on the concave side (which tend to accentuate lateral bending)
- When sitting, the body weight is distributed along the short side with a clear asymmetry of back
- When standing, the body weight is distributed mostly on the outside part of one foot
- Ribs on the shortest side close each other and approached horizontalisation
- Ribs on the longest side become less close and get a vertical orientation, forming a more or less pronounced "hump".
- Little torsion of the chest respect to the pelvis compared with floating ribs forward
- Inability to effectively align the skeleton for the various motor functions.

 

Evolution of scoliosis

  1. Rotation of the vertebrae: is considered the dominant element in the formation of scoliosis.
  2. Body Asymmetry: disparate distribution of viscera and their weight on the right and left side.
  3. Brain lateral orientation: The brain has two hemispheres, left and right. The center of the language for 95% of cases and is the predominant on the left: right-handed. This leads to a functional asymmetry of the nervous system and the control of vascular tone and, according to that, a person will tend to lean on the stronger muscles sloping on a side, accentuating the rotation of spine.
  4. Costal movements: on one side ribs become closer than on the other side. This couple of forces aggravates the rotation of the spine.
  5. Muscles: The large muscles of the abdomen exacerbate the scoliotic rotation, as well as the action of gravity and increases the curve of the posterior muscles pushing the column towards the convexity.
  6. Skipping of evolutive stages: if a child did not crawl and did not have the opportunity to explore and conquer the surrounding space, in adulthood has motor coordination problems, because it is on the floor that the child develops neuro-muscular system and sophisticated learning sophisticated antigravity mechanisms, living on his own body evolutionary stages of our own species. Skipping even one step predisposes the deviations on adulthood.
  7. Limited psychomotor activity: There are interactions between child activity and brain development. A modification affects the other as a constant retroactive process as indicated by the diagram below.

So the personal experience during childhood is the key to the greatness or failure in adolescence and adulthood.
