Abstract

BackgroundWe 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.MethodsA female with adolescent idiopathic scoliosis was first seen at age 13 years, 0 months with a Risser 0. She had a 43o left lumbar, 15o right 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.ResultsAt 6 months, her lumbar and thoracic curves measured 41o and 28o, respectively. At 18 months, her lumbar and thoracic curves measured 47 o and 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 43o and 32o, respectively. At 30 months, she performed unsolicited corrective exercises during the x-ray. Her lumbar and thoracic curves measured 26o and 41o, respectively. Another x-ray in the relaxed position revealed lumbar and thoracic curves measuring 39o and 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.ConclusionAfter 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.

Highlights

We are unaware of any studies describing the immediate effects of scoliosis-specific exercises on the Cobb angle measured by radiograph
The aim of this study is to describe the differences between radiographs obtained with and without corrective exercises after initial training and after one year
The Cobb angle at the lumbar curve improved in the relaxed standing position by 8 o in the standing relaxed position compared to the 18 month visit

Summary

Introduction

We are unaware of any studies describing the immediate effects of scoliosis-specific exercises on the Cobb angle measured by radiograph. Auto-corrective exercises are integral to scoliosis-specific exercises [1,2,3,4]. The Cobb angle measured by radiograph is the most commonly used outcome measure to assess curve magnitude [5]. It is unclear whether and how corrective exercises affect the Cobb angle. We are unaware of any studies describing the immediate effects of scoliosis-specific exercises on the Cobb angle. In an article on the Scientific Exercise Approach to Scoliosis (SEAS) method, Romano et al [10] demonstrated x-ray images of one patient in a relaxed position and during corrective exercises [10]. The aim of this study is to describe the differences between radiographs obtained with and without corrective exercises after initial training and after one year
