【 摘 要 】

Scoliosis as a spinal disorder is very frequent in children population. The objective parameter to define the gravity of scoliosis and to assess its evolution is the Cobb angle. The variation of the Cobb angle in different tilted positions is studied within an experimental program. Data is acquired from a set of sensors attached to the patient's back and is processed to provide the Cobb angle. The mathematical approach is based on a fifth degree polynomial, which approximates the shape of the column. The results show that lumbar and thoracic Cobb angle vary in opposite directions, so that the flexion to the right and to the left aggravates the scoliosis, no matter on which side it is.
