Abstract
BackgroundThere is controversy as to whether conservative management that includes wearing a brace and exercises is effective in stabilising idiopathic scoliosis curves. A brace only prevents progression of the curve and has been shown to have favourable outcomes when patients are compliant. So the aim of this study was to: determine the effect of compliance to the Rigo System Cheneau (RSC) brace and a specific exercise programme on Idiopathic Scoliosis curvature; and to compare the Quality of Life (QoL) and psychological traits of compliant and non compliant subjects.MethodsA pre/post test study design was used with a post study comparison between subjects who complied with the management and those who did not. Fifty one subjects, girls aged 12-16 years, Cobb angles 20-50 degrees participated in the study. Subjects were divided into two groups, according to their compliance, at the end of the study. The compliant group wore the brace 20 or more hours a day and exercised three or more times per week. The non-compliant group wore the brace less than 20 hours a day and exercised less than three times per week. Cobb angles, vertebral rotation, scoliometer readings, peak flow, quality of life and personality traits were compared between groups, using the student’s two sample t-test and an analysis of covariance.ResultsThe compliant group, wore the brace 21.5 hours per day and exercised four times a week, and significantly improved in all measures compared to non compliant subjects, who wore the brace 12 hours per day, exercised 1.7 times a week and significantly deteriorated (p < 0.0001). The major Cobb angles in the compliant group improved 10.19°(±5.5) and deteriorated 5.52°(±4.3) in the non compliant group (p < 0.0001). Compliant subjects had a significantly better QoL than the non compliant subjects (p = 0.001). The compliant group were significantly more emotionally mature, stable and realistic than the non compliant group (p = 0.03).ConclusionsGood compliance of the RSC brace and a specific exercise regime resulted in a significant improvement in curvatures, poor compliance resulted in progression/deterioration. A poorer QoL in the non compliant group possibly was caused by personality traits of the group, being more emotionally immature and unstable.
Highlights
The cause of spinal deformity is a problematic developmental process, the outcome of which can be altered with appropriate intervention and there is some evidence that scoliosis is reversible [1,2,3]
Subjects were divided into two groups according to their compliance, which was recorded in their diaries after the brace and exercise interventions were complete and when weaning out of the brace had begun

Summary
The cause of spinal deformity is a problematic developmental process, the outcome of which can be altered with appropriate intervention and there is some evidence that scoliosis is reversible [1,2,3]. Opinions vary about the efficiency of conservative treatment of scoliosis [4,5] with the efficiency of bracing continuing to be questioned [6,7,8]. The primary aim of conservative scoliosis management is to stop curvature progression [5,8,13,14,15] and to avoid surgery [16]. There is controversy as to whether conservative management that includes wearing a brace and exercises is effective in stabilising idiopathic scoliosis curves. The aim of this study was to: determine the effect of compliance to the Rigo System Cheneau (RSC) brace and a specific exercise programme on Idiopathic Scoliosis curvature; and to compare the Quality of Life (QoL) and psychological traits of compliant and non compliant subjects
