title: Immediate effects of scoliosis-specific corrective exercises on the Cobb angle after one week and after one year of practice.
abstract: BACKGROUND
  We are unaware of any studies describing the immediate effects of scoliosis-specific exercises on the Cobb angle measured by radiograph. This study aimed to describe the differences between radiographs obtained with and without corrective exercises after initial training and after one year.
  
  
  METHODS
  A female with adolescent idiopathic scoliosis was first seen at age 13 years, 0 months with a Risser 0. She had a 43oleft lumbar, 15oright thoracic curve. She was seen again after 6, 18 and 30 months and performed exercises from 18 to 30 months. She performed Barcelona Scoliosis Physical Therapy School (BSPTS) exercises for a four-curve type (lumbar dominant with pelvis deviation to the lumbar concave side). At 18 and 30 months, x-rays were obtained with and without performing corrective exercises.
  
  
  RESULTS
  At 6 months, her lumbar and thoracic curves measured 41oand 28o, respectively. At 18 months, her lumbar and thoracic curves measured 47oand 30o, respectively. Also at 18 months, immediately after her x-ray in the relaxed standing position, she performed her corrective exercises in standing with arms lowered for a second x-ray. Her lumbar and thoracic curves remained similar and measured 43oand 32o, respectively. At 30 months, she performed unsolicited corrective exercises during the x-ray. Her lumbar and thoracic curves measured 26oand 41o, respectively. Another x-ray in the relaxed position revealed lumbar and thoracic curves measuring 39oand 35o, respectively. The immediate effect of corrective exercises after a year of training was a 33 % improvement at the lumbar spine compared to only a 9 % improvement the previous year.
  
  
  CONCLUSIONS
  After initial training, corrective exercises during a standing x-ray did not significantly improve the Cobb angle for the major lumbar curve compared to the relaxed standing x-ray. However, a year after performing exercises, unsolicited corrective exercises resulted in a significantly improved Cobb angle compared to relaxed standing for the curve primarily targeted by the exercise program. Improved exercise ability and spinal flexibility may have contributed to the improved Cobb angle.
