“…22 But the effects of bracing on respiratory mechanics may vary according to curve magnitude, brace design, restrictive effects on rib cage and trunk mobility, applied corrective forces, how long the brace is worn, and so on. 4,8 In this study, the unbraced and braced condition comparisons have shown that there was a mild decrease (defined by the American Thoracic Society) 23 in FEV 1 (with mean change 18.8%), VC (with mean change 12.4%), FVC (with mean change 18.4%), MVV (with mean change 11.7%), and PEF (with mean change 18.4%) values of spirometric measurements while wearing a brace when compared with the unbraced condition. These alterations may be due to the correcting forces exerted by the brace and its possible limiting effect on the expansion of the rib cage during inspiration.…”

“…3 Therefore, the effects of bracing on thorax mechanics, chest mobility, and pulmonary functions are considered inevitable. 4 Bracing has important positive effects on scoliosis treatment in the long term, such as reducing curve magnitude and rib hump, and improving cosmetic appearance and trunk symmetry. 5,6 However, wearing a brace for many years can be a traumatic experience for adolescents.…”

Background: Despite the common use of braces to prevent curve progression in idiopathic scoliosis, their functional effects on respiratory mechanics have not been widely studied. Objective: The objective was to determine the effects of bracing on pulmonary function in idiopathic scoliosis. Methods: A total of 27 adolescents with a mean age of 14.5 ± 1.5 years and idiopathic scoliosis were included in the study. Pulmonary function evaluation included vital capacity, forced expiratory volume, forced vital capacity, maximum ventilator volume, peak expiratory flow, and respiratory muscle strengths, measured with a spirometer, and patient-reported degree of dyspnea. The tests were performed once prior to bracing and at 1 month after bracing (while the patients wore the brace). Results: Compared with the unbraced condition, vital capacity, forced expiratory volume, forced vital capacity, maximum ventilator volume, and peak expiratory flow values decreased and dyspnea increased in the braced condition. Respiratory muscle strength was under the norm in both unbraced and braced conditions, while no significant difference was found for these parameters between the two conditions. Conclusion: The spinal brace for idiopathic scoliosis tended to reduce pulmonary functions and increase dyspnea symptoms (when wearing a brace) in this study. Special attention should be paid in-brace effects on pulmonary functions in idiopathic scoliosis. Clinical relevance Bracing seems to mimic restrictive pulmonary disease, although there is no actual disease when the brace is removed. This study suggests that bracing may result in a deterioration of pulmonary function when adolescents with idiopathic scoliosis are wearing a brace.

“…The scientific literature is in agreement that with appropriate indications-still-growing and well-documented progressive curves between 20 • and 45 • -a well-designed and adapted brace can provide a correction of 50%, which can stop the curve's progression in most cases [8]. However, the effects of bracing on thorax mechanics, chest mobility, and pulmonary functions are considered inevitable [11]. Other conservative methods, based on exercise approaches, such as Schroth exercises [12], or Global Postural Reeducation (GPR) [13], may be beneficial and appear to cause fewer adverse effects because they allow the patient to move without restriction.…”

Adolescent idiopathic scoliosis (AIS) is a lateral curvature of the spine with a Cobb angle of at least 10° with an unknown etiology. It is recognized that AIS may affect respiratory function. This study aims to describe and compare respiratory function in a case series of patients with scoliosis who underwent different types of therapeutic management: no intervention, orthotic brace, and global postural reeducation (GPR). Fifteen AIS patients were included in this study (seven no intervention, four orthotic brace and four GPR). Lung function and inspiratory muscle strength were measured and analyzed, as well as sociodemographic, clinical, and anthropometric variables. Significant correlations were observed between height (cm) and maximum inspiratory pressure (MIP) reference (cmH2O) and forced vital capacity (FVC) (liters) (r = 0.650 and r = 0.673, respectively; p < 0.01); weight (Kg) and MIP reference (cmH2O) (r = 0.727; p < 0.01); and Main curve degrees (Cobb angle) and FVC% (r = −0.648; p < 0.01). The AIS cases that underwent GPR treatment presented a greater MIP (% predictive) compared to the no intervention and brace cases (201.1% versus 126.1% and 78.4%, respectively; p < 0.05). The results of this case series show a possible relation whereby patients undergoing treatment with the GPR method have greater inspiratory muscle strength compared to the no intervention and brace cases. Studies with larger samples and prospective designs must be performed to corroborate these results.

“…These braces are prescribed by physicians to patients and by wearing them, after a while, the structure and shape of the spinal cord are reversed. [9][10][11] Today, researchers are reviewing a variety of brace models so that, by designing and analyzing a variety of braces, they are planning to present the best and most recent models for scoliosis patients. [12][13][14] This study has been designed to simulate and compare braces composed of three different materials to determine the optimal material.…”

ne of the wonders of creation in humans is symmetry as this symmetry brings about balance and beauty. The human spinal cord, as the axis of this symmetry, has its own defining principles and curvature. The spinal cord is vital in withstanding body weight and focused pressure, as well as maintaining the nervous system and performing different body movements.One of the consequences of modern life is the appearance of conditional disorders and pain in musculoskeletal structures especially in young people. These disorders are caused by several factors such as motion poverty, muscle imbalances, individual physical characteristics, physical maturity especially rapid bone growth, nutrition disorders especially vitamin D deficiency, long periods of sitting, inappropriate ways of carrying bags, improper motion patterns, psychological characteristics and also congenital factors. These problems cause illnesses such as kyphosis, which is as a uniform arch on the top of spinal cord, and musculoskeletal disorders, such as scoliosis, which may appear as a unilateral deviation (C-form deviation) or as a bilateral deviation (S-form deviation) of the spinal cord. 1The International Scientific Society on Scoliosis Orthopedic and Rehabilitation Treatment (SOSORT) recommends the following treatments based on the Cobb angle. However, individual treatment may vary depending on speed of progression and remaining skeletal growth (< 20°:
