Background/Objectives: Adolescent Idiopathic Scoliosis (AIS) is a lateral curvature of the spine combined with rotation and associated postural changes. Curves are classified according to direction and the spinal region, with right thoracic curves being a common presentation. Curve magnitude is measured using Cobb angles on radiographs and is used to monitor curve progression, with one of the main aims of treatment being prevention of progression to surgical levels. Treatment options may include observation, physiotherapeutic scoliosis-specific exercises (PSSE), thoracolumbosacral orthotic (TLSO) bracing, or surgery and are dependent on curve magnitude, risk of progression, and patient goals. Methods: This case series includes five patients (four female and one male, mean age of 14.8 y) who received previous non-surgical treatment without success and had severe right thoracic AIS with an average Cobb angle measurement of 53.4°, involving spinal curve magnitudes that warrant surgical recommendation. Results: These patients’ curves were successfully reduced to nonsurgical levels utilizing a non-surgical, multimodal treatment approach combining 3D corrective TLSO bracing using the ScoliBrace^®, PSSEs, and spinal rehabilitation over an average of 37.0 months. The average Cobb angle reduced from 53.4° to 29.6° (44.6% reduction) after being weaned off treatment. Conclusions: This series has shown successful, clinically significant improvement in Cobb angle and trunk symmetry in five patients with severe AIS using a non-surgical, multimodal approach combining 3D corrective TLSO bracing using the ScoliBrace^® and spinal rehabilitation procedures. Further investigation into this multimodal non-surgical approach for children, parents, and healthcare providers and policymakers seeking an alternative to surgical intervention for AIS is warranted.

Scoliosis is one of the most common spinal deformities, which affects millions of people worldwide. Bracing and physiotherapy exercises represent the first-line, non-invasive approaches for managing scoliosis. In recent years, the use of wearable devices has spread as a novel approach to the treatment of scoliosis. However, their effectiveness in treatment planning and outcomes has not been thoroughly evaluated. This manuscript provides a scoping review of the classification and application of wearable devices and the role of artificial intelligence (AI) in interpreting the data collected by wearable devices and guiding the treatment. A systematic search was carried out on Scopus, Web of Science, PubMed, and EMBASE for studies published between January 2020 and February 2025. A total of 269 studies were screened, and 88 articles were reviewed in depth. Inclusion criteria encompassed articles focusing on wearable devices integrated into smart braces, rehabilitation systems for scoliosis management, AI and machine-learning (ML) applications in scoliosis treatment, virtual reality (VR), and telemedicine for scoliosis care. The literature shows that the use of wearable devices can enhance scoliosis treatment by improving the efficiency of braces and enabling remote monitoring in rehabilitation programs. However, more research is needed to evaluate user compliance, long-term effectiveness, and the need for personalized interventions. Future advancements in artificial intelligence, microsensor technology, and data analytics may enhance the efficacy of these devices, which can lead to more personalized and accessible scoliosis treatment.

Background: Severe scoliosis can lead to chronic low back pain (cLBP) and may progress in adulthood. While day-time bracing is commonly used to alleviate pain and improve function, the role of night-time bracing remains unclear. This study aimed to assess the six-month effectiveness of a custom-made night-time brace in reducing pain in adults with scoliosis, compared to a prefabricated brace worn for 2–4 h during the day. Methods: A retrospective cohort study was conducted at a tertiary outpatient clinic specializing in spinal deformities. Adults with scoliosis (≥30° Cobb) and cLBP were divided into two groups: the study group used a custom-made night-time thoracolumbosacral orthosis (TLSO), while the control group wore a prefabricated brace (Peak) for 2–4 h daily. Pain and functional outcomes were assessed at baseline and after six months. Results: The study group included 25 women (mean age, 62.3 ± 9.5 years; Cobb angle, 60.4 ± 17.7°) who wore the night-time brace for an average of 7.2 ± 2.2 h per night. The control group comprised 20 women (mean age, 67.8 ± 10.5 years; Cobb angle, 61.9 ± 12.6°). At six months, the worst pain significantly improved in the TLSO group compared to the Peak group (F = 6.32, p = 0.0158). However, no statistically significant differences were observed between groups for back pain, leg pain, Core Outcome Measures Index (COMI), or Oswestry Disability Index (ODI). Conclusions: Night-time bracing shows interesting results on pain at six months in adults with severe scoliosis and back pain. These preliminary results open a new perspective that needs further verification and will help design more robust studies to verify what we found and identify the population more responsive to this approach.

This report provides a concise selective representative overview of the predictor factors for progression in Idiopathic Scoliosis (IS). The Cobb angle method, rib hump deformity, imaging and advanced techniques for assessing skeletal maturity serve as key elements in evaluating prognostic factors for IS progression based on the patient’s age at diagnosis—particularly in Infantile Idiopathic Scoliosis (IIS), Juvenile Idiopathic Scoliosis (JIS), and Adolescent Idiopathic Scoliosis (AIS). The commonly used approaches for determining skeletal maturity include the assessment of the iliac apophysis and scoliosis curve deterioration, the Sanders skeletal maturity staging system, the distal radius and ulna (DRU) classification for predicting growth spurts and curve progression in IS, as well as the ossification of vertebral epiphyseal rings, the humeral head, and the calcaneal apophysis. Prognostic factors influencing IS progression are further discussed in relation to the patient’s age at onset—whether in infancy, childhood, or adolescence—as well as in both untreated and braced AIS patients. Additionally, the apical convex rib–vertebra angle in AIS is explored as an indicator of progression. Predictors for curve progression at skeletal maturity are outlined, along with various models for forecasting IS deterioration. Lastly, the Rib and Segmental Rib Index, a rib cage deformity parameter, is introduced as a predictor of scoliosis progression. In conclusion, this concise and selective overview of predictor factors for progression in IS highlights the current understanding of IS progression factors. It also introduces the Rib and Segmental Rib Index—a rib cage deformity parameter—as a predictor of IS progression. Full article

This opinion article refers to the “double rib contour sign” and to the rib index (DRCS and RI), to their reliability study results in the chest radiographs of a control group and to their validity study results. These two parameters were introduced by the first author in this report. The introduction of the Segmental Rib Index (SRI) and its relation to spinal deformity is also discussed. The RI has been confirmed to be a strong surrogate for scoliometric readings in idiopathic scoliosis (IS). The clinical applications of the RI are analyzed for the following: (a) the documentation of deformity; (b) the assessment of physiotherapy outcomes (PSSEs); (c) the documentation of the outcomes of brace treatment; (d) the documentation of the pre- and post-operative assessment of thoracic deformity correction in different types of instrumentation; (e) its usage in prognosticating accelerated deterioration in skeletally mature adolescent idiopathic scoliosis (AIS) curves of 40–50 degrees; and (f) its usage in the recognition of the proper rib level for thoracoplasty/costoplasty. The emerging etiological–scoliogenic implications from the use of the DRCS and RI are described. The rotation of the trunk and vertebral bodies as interrelated, but distinct parameters are finally analyzed. Full article

Adolescent idiopathic scoliosis (AIS) is treated with various forms of conservative care or surgery, depending on the degree of severity. When AIS is detected early, it can be monitored and initially treated with reduced invasiveness to prevent further progression. AIS manifests itself through deformations of the trunk, which are mostly identified as asymmetries in manual clinical examination. Torsobarography is a new pressure-based surface topographic system for posture analysis and evaluates such associated morphologic asymmetries. The aim of this study is to investigate the diagnostic validity of torsobarography by examining correlation of extracted torsobarographic indices with the Cobb angle and its ability to differentiate between different severities of scoliosis: no scoliosis, mild scoliosis, and moderate scoliosis. A total of 87 subjects (51 females and 36 males) were examined with torsobarography. Six torsobarographic indices were calculated for all subjects: torsobarography angle (TBA), sagittal imbalance index (SII), torso asymmetry index (TAI), shoulder asymmetry angle (SAA), waist asymmetry angle (WAA), and pelvis asymmetry Angle (PAA). These indices were correlated with the Cobb angle, and the differences between severities were statistically analyzed. Three out of six indices (TBA, TAI, and WAA) were able to significantly distinguish between mild and moderate scoliosis. Additionally, those indices showed moderate correlation ($\rho$ = 0.37–0.50) with the Cobb angle measurements. The WAA was the only statistically significant index capable of differentiating between no scoliosis and moderate scoliosis. This study is the first to demonstrate that torsobarography can distinguish between different severities of scoliosis and thus identify a scoliotic deformity that requires bracing over monitoring.

Background: All-day braces are predominantly used for the conservative treatment of adolescent idiopathic scoliosis (AIS). The Charleston Bending Brace is a pure nighttime brace. The aim of this study was to investigate the primary in-brace correction of the main curve of AIS when treated with the Charleston Bending Brace. Specifically, the factors influencing major curve correction were examined. Methods: The retrospective analysis included 97 patients with AIS who were treated between October 2010 and September 2020. Patients with secondary scoliosis or orthotic pretreatment were excluded. Standardized radiographs were used to determine the Cobb angle of the major and minor curves. Curve correction in relation to Lenke’s classification, the Risser stage, and rotation were assessed at four different time points (t0: before treatment, t1: 6–12 months, t2: 13–24 months, and t3: 25–36 months during treatment). Results: The average Cobb of the main curve at the beginning of the study was 25.7°. The night brace achieved excellent in-brace correction at t1, with nearly half of the patients (43%) showing a correction exceeding 80%. Curve localization, the Lenke type, and the Nash–Moe rotation significantly influenced initial in-brace curve correction at t1. At t2, there was also a significant in-brace correction of the initial Cobb by 93.0%. Similar improvements were observed at t3 for in-brace correction as well as without the brace (p < 0.031). Conclusions: The results of the study revealed good primary in-brace correction of the main curve of the AIS with the nighttime brace, which was at least equivalent when compared to values from the literature for the Chêneau brace. Also, while restricted to medium-term results due to our study limitations, the percentage of correction in out-of-brace data of our patients was similar to weaned 24 h brace patients. Full article

Background/Objectives: Bracing is an effective treatment for preventing curve progression in skeletally immature adolescent idiopathic scoliosis (AIS) patients. A novel hybrid brace has been developed to overcome the limitations of conventional rigid and soft braces. This study aimed to evaluate the clinical efficacy of the novel hybrid brace. Methods: We enrolled AIS patients who were candidates for brace treatment: aged 10–18 years, with a coronal Cobb angle of 20–45° and a Risser stage of 0–2. The primary outcome was the rate of successful brace treatment, defined as meeting all three criteria: (1) less than 5° of progression in the Cobb angle during follow-up, (2) less than 45° of Cobb angle at the final follow-up, and (3) avoidance of surgical treatment. Results: A total of 24 patients (1 male, 23 female) with a mean age of 12.2 ± 1.2 years were included in this study. At the initiation of bracing, the major curve had a mean Cobb angle of 34.5 ± 6.3° and an in-brace correction (IBC) rate of 41.5 ± 16.0%. The hybrid brace demonstrated a success rate of 91.7% (22/24) during a mean follow-up period of 22.1 ± 6.4 months. After brace treatment, seven (29.2%) patients showed an improvement of more than 5° in their Cobb angle. When compared to a matched control from a retrospective cohort, the hybrid brace demonstrated a greater success rate (91.7% vs. 83.3%) and a higher proportion of patients with an improved curve (29.2% vs. 12.5%), although statistically insignificant. Conclusions: A novel hybrid brace was effective in preventing curve progression in skeletally immature patients with AIS. Full article

Bracing is a widely used conservative treatment for adolescent idiopathic scoliosis (AIS) patients, yet there is no consensus on the optimal amount of force applied. Although a number of different sensors have been developed to continuously monitor the applied pressure and force, they have several limitations, including inadequate overall force distribution and displacement. They also cause discomfort with limited wearability. In this study, body pressure mapping knitwear (BPMK) integrated with fourteen silicone-embedded fiber Bragg grating (FBG) sensors is developed to monitor immediate and overall changes in force during the bracing treatment. A wear trial of the BPMK is conducted by using a validated soft AIS mannequin, and prediction equations have been formulated for the FBG sensors at individual locations. The findings indicate that the measured forces are in good agreement with those obtained from clinical studies, with peak forces around the padding regions reaching approximately 2N. This was further validated by using finite element (FE) models. When comparing X-ray images, the estimated differences in Cobb angles were found to be 0.6° for the thoracic region and 2.1° for the lumbar region. This model is expected to provide valuable insights into optimal force application, thus minimizing the risk of injury and enhancing bracing compliance and efficacy. Ultimately, this innovative approach provides clinicians with data-driven insights for safer and more effective bracing applications, thus improving the quality of life of AIS patients. Full article

Background: The purpose of this systematic review was to investigate the clinical outcome measures, either in separation or in conjunction with the Cobb angle, that were employed in randomized controlled trials to evaluate posture and spinal deformity. Methods: The PubMed, PEDro, OVID, and Scopus electronic databases were used to search for published articles from January 2004 to May 2024. All the searches included English language studies. Keywords were determined as “scoliosis, exercise, physical activity, brace, bracing, conservative treatment, rehabilitation, physiotherapy and physical therapy”. Results: The most commonly used clinical evaluation parameters other than the Cobb angle in the studies were the ATR and surface topography measurements. The most commonly used assessment methods were POTSI asymmetry assessment performed with measurements made on photographs, the WRVAS, a deformity perception assessment evaluated with different photographs, and the SRS-22 scale, a disease-specific quality of life assessment. Conclusions: New developments in the treatment of scoliosis have brought about alternative measurement techniques that offer a more comprehensive view of patient outcomes. As a result of the review of the literature, it has emerged that radiation-free, valid, and reliable multidimensional evaluations should be performed in follow-up and treatment efficacy evaluations after initial diagnosis in adolescent idiopathic scoliosis.

Background/Objectives: Spinal flexibility radiographs are important in adolescent idiopathic scoliosis (AIS) for clinical decision-making. In this study, we introduce a new method, the ‘quantitatively controlled standing fulcrum side-bending’ test (CSFS test). This is a feasibility study; we aimed to quantify the applied force and track the temporospatial changes in the spine specifically by measuring the continuous change in the Cobb angle (in degrees) during lateral bending. Methods: In this cross-sectional study, we included patients with AIS. Using a low-dose cinematic fluoroscopic technique, we captured the lateral bending of the thoracolumbar vertebral spine while inducing quantified lateral force on the ribs by a force gauge in a three-point fixation setup of controlled lateral bending. Trial registration number: H-1703423. Results: Twenty-one patients with small-curve AIS were included as subjects. All subjects performed the CSFS test adequately. They had small curves with a mean Cobb angle of 12.0 (range: 0.0–26.0, SD: 7.1). The measured median stiffness was 3.66 N/degrees (°) of the Cobb angle (range: 0.02–11.81) with a median coefficient of determination R² of 0.58 (range: 0.002–0.92) by regression analyses. When analysed concerning the median-term clinical outcome of either progression/regression or stationary curves, various Cobb angle measurements and the other experimental parameters, there were no significant relationships. Conclusions: The CSFS test is feasible to quantify the force applied and the temporospatial changes in the spine during lateral bending. The CSFS test has been utilised in basic research for mechanical characterisation of the scoliotic spine and has the potential of being implemented directly in patient-specific bracing to estimate the forces needed for brace correction and adjustment so as not to supersede the allowed skin pressure.

This study aimed to evaluate the efficacy of a novel three-dimensional (3D) spinal decompression and correction device in improving the in-brace correction and patient comfort level for adolescents with idiopathic scoliosis (AIS), and to assess the impact of the number of vertebrae involved in the scoliotic curve on the correction’s effectiveness. A single-centre, single-blinded randomized controlled trial (RCT) was conducted in 110 AIS patients aged 10–18 years who were randomly allocated into four groups receiving 0–3 days of device intervention. Each session lasted for 30 min and was conducted twice daily. Significant improvements were observed in both the in-brace correction ratio and patient comfort level, particularly in the 2- and 3-day intervention groups (p < 0.001). The number of involved vertebrae for a scoliotic curve was positively correlated with the in-brace correction ratio in the no intervention (or 0-day) and 1-day intervention groups, while this correlation varied in the 2- and 3-day intervention groups. These findings suggested that the prolonged use of the 3D device could improve the correction ratios and patient comfort, while the role of vertebrae involvement in predicting the initial correction may require further exploration to optimize personalized treatment strategies in future clinical practice.

Objectives: The aim of this study was to evaluate the effect of brace use application and the Schroth intervention on lung ventilation and respiratory muscle strength in patients treated long-term with a Chaneau brace and the Schroth method. Methods: A total of 26 post-menarche females aged 15.7 ± 1.5 years, with a Cobb angle of 18–48° and a diagnosis of AIS in inpatient rehabilitation were examined. All participants received brace treatment for a minimum of 3 months with a dosage of 20–22 h/day. This study protocol was performed three times: 1—brace intervention—first day of the present study; 2—without the brace—second day of the present study; and 3—Schroth intervention on the same day. Results: During the period of brace use, girls treated with a long-term therapy showed significantly reduced values for VC, FVC, and FEV₁ and significantly higher values for inspiratory muscle strength PI_max compared to values obtained in studies without the brace and after single exercises. Expiratory muscle strength did not differ significantly. Conclusions: The majority showed restrictive lung ventilation disorders and decreased respiratory muscle strength in relation to norms. There was a significant correlation of PI_max with the duration of wearing the brace and the duration of therapy. Full article

Background and Objectives: Adolescent Idiopathic Scoliosis (AIS) affects individuals aged 10–18 years and is characterized by spinal deformity, three-dimensional axis deformation, and vertebral rotation. Schroth method exercises and braces have been shown to reduce the Cobb angle and halt spinal deformity progression. The aim of this study was to investigate the impact of a 12-month, supervised Schroth exercise program on scoliosis severity and quality of life in adolescents with AIS. Materials and Methods: Eighty adolescents with AIS (aged 10–17 years) were prescribed a brace and were divided into two groups. The intervention group followed a supervised Schroth exercise program three times a week for 12 months in addition to wearing a brace. The control group used only the brace. Outcomes included the Cobb angle of the main curvature and the sum of curves using radiography, the maximum angle of trunk rotation (ATR maximum, using a scoliometer), and quality of life with the Scoliosis Research Society-22 (SRS-22) questionnaire. Evaluations were conducted at baseline, after 12 months, and 6 months post-intervention. A multivariate analysis of covariance (MANCOVA) was used for statistical analysis (p-Value < 0.05). Results: The intervention group showed statistically significant improvement compared to the control group in the 12th month in Cobb angle (mean differences, 95% CI: −3.65 (−5.81, −1.53), p-Value < 0.001, Cohen’s d = 0.30), ATR maximum (mean differences, 95% CI: −3.05 (−3.86, −2.23), p-Value < 0.001, Cohen’s d = 0.74), and SRS-22 score (mean differences, 95% CI: 0.87 (0.60, 1.13), p-Value < 0.001, Cohen’s d = 0.58). Differences in ATR maximum and SRS-22 score remained significant at the 18-month measurement. No significant differences were found between groups in the sum of curves (p-Value > 0.05). Conclusions: A 12-month supervised Schroth exercise program in AIS patients undergoing brace treatment significantly improves scoliosis severity (Cobb angle and ATR maximum) and quality of life. Improvements were greater than those in shorter-duration studies, suggesting a linear dose–response relationship. Further clinical studies are needed to clarify the impact of long-term Schroth programs. Full article

This study aimed to analyze both thoracic and lumbar erector spinae muscle activations during three different types of 3-dimensional elongation exercises in individuals with adolescent idiopathic scoliosis (AIS). Participants included 24 adolescents with AIS with a double curve (S type scoliosis), meeting specific criteria, such as a Cobb angle between 10° and 20° and not having undergone surgical or brace treatments. Electromyography (EMG) data were collected to evaluate muscle activation. Three-dimensional scoliosis-specific exercises were applied as 3 different exercise types with TheraBand resistance, manual stimulation, and breathing inducement from convex side to concave side until a symmetric position was maintained with self-correction. Different exercise types significantly affected muscle activity, with the highest activations in TheraBand resistance, followed by manual and just breathing inducement conditions for the convex and concave sides of the thoracic and lumbar regions. This suggests that exercise type significantly impacts muscle engagement in AIS patients, providing valuable insights for targeted exercise program design. Specially, the muscle activation of TheraBand resistive exercise can be an alternative with more muscle activation and motivational effects during a 3D scoliosis-specific exercise program.
