Specific exercises and brace treatment are the two evidence-based modes of treatment for patients with scoliosis. The purpose of this paper is to present the first end-results from a prospective cohort that commenced treatment in 2011 with a CAD based Chêneau derivate and is then compared to the published results achieved with the Boston Brace. [Participants and Methods] Inclusion criteria for the study, refers to the SRS inclusion criteria on bracing, except the range of Cobb angles which was extended to curvatures of up to 45°. Twentyeight patients were weaned from their CAD Chêneau style brace. The results of this cohort have been compared with the BRAIST study by Weinstein et al. with the help of the Z-test. [Results] A success rate of 92.9% has been achieved. This was compared to the success rate of 72% in the BRAIST study. The differences were highly significant in the Z-test. [Conclusion] The results achieved with the GBW are significantly and better than the results achieved with the Boston brace. Therefore, the standards for bracing should be reviewed with the results that symmetric compression with Boston bracing is not as successful, when compared to asymmetric high correction bracing results, which allow a standardized classification-based corrective approach.

“…Thus, it is also an important goal to restore the sagittal balance in the AIS patients. However, Fang et al [23] found bracing did not significantly improve sagittal Cobb's angle, although increased it in some patients. Accordingly, we proposed it might not be enough to give brace treatment for a patient with smaller sagittal Cobb's angle of the thoracic curve, which seemed to be in consistent with the conclusion of Yu et al [14] …”

Pulmonary function changes and its influencing factors after preoperative brace treatment in patients with adolescent idiopathic scoliosis

et al. 2016

Background:The aim of the study was to retrospectively investigate the changes in pulmonary function and its influencing factors in patients with adolescent idiopathic scoliosis (AIS) undergoing preoperative brace treatment or not.Methods:Total 237 AIS patients (43 boys, 194 girls) who underwent operations and had a complete record of pulmonary function tests were enrolled and were divided into preoperative brace treatment group (brace treatment group, n = 60) and without preoperative brace treatment group (control group, n = 177). The pulmonary function parameters were compared between the 2 groups. Multiple linear regression analysis was performed to explore whether the variables, including age at operation, height, coronal Cobb's angle of main curve, number of involved vertebrae, sagittal Cobb's angle of thoracic curve, brace treatment time per day and brace treatment duration, influenced pulmonary function in the brace treatment group.Results:No significant differences were observed in both predicted and actually measured value of forced vital capacity (FVC) and predicted value of forced expiratory volume in 1 s (FEV1) between 2 groups (P > 0.05), but actually measured FEV1, the percentage of actually measured and predicted value of FVC (FVC%) and FEV1 (FEV1%) were significantly lower in the brace treatment group than those in the control group (P < 0.05). Importantly, the above changes in actually measured FEV1 and FEV1% were obvious in AIS patients presented with a main thoracic curve (P < 0.05), but not in patients with a primary thoracolumbar/lumbar curve. Multiple linear regression analysis indicated that only the sagittal Cobb's angle of the thoracic curve was positively, but preoperative brace treatment duration was negatively associated with both the FVC% and FEV1% (P < 0.05).Conclusion:Preoperative brace treatment may deteriorate pulmonary function in AIS patients with thoracic curve. The small sagittal Cobb angle and longer brace treatment duration may be risk factors for reduced pulmonary function.

“…Symmetrical braces (Boston style with dorsal or ventral closures) provide success rates of 70% or little over [7,9,[32][33][34][35] (Figure 2). Asymmetrical threedimensional braces (mainly Chêneau style) may have success rates between less than 50 and more than 90% [8,[36][37][38][39][40][41][42][43][44][45][46][47][48][49]. There is a wide variety of outcomes used in research, which may be related to the differing qualities of asymmetrical brace adjustments and designs (Figures 3-5).…”

“…Brace treatment is supported by high-quality evidence as well [7][8][9]; however, the approach to bracing differs significantly in design (Figure 1). There are many types such as symmetrical braces [7,9,[32][33][34][35], asymmetrical braces [8,[36][37][38][39][40][41][42][43][44][45][46][47][48][49], night-time braces [50][51][52][53][54][55] and soft braces [56,57]. It has been shown that soft braces have no advantage over hard braces [8,[58][59][60].…”

The aim of brace treatment in patients with scoliosis during growth is (1) to stop curve progression and (2) to improve appearance/cosmesis. There is high quality evidence available supporting brace treatment. According to recent publications, the outcomes of different braces vary to a high extent. Although most of the scoliosis cases will not affect the patient's health, the impact of braces on the cosmetic outcome to date is not well determined. Standardised asymmetric braces (mainly Chêneau derivatives) have better outcomes than symmetric compression braces and may also lead to significant improvements of the deformity. For symmetric braces, no evidence exists that these could significantly change the deformity. Soft braces have no indication and the use of night-time braces should be largely restricted due to poor outcomes when compared to current standards of full-time bracing.
