“…To investigate the factors involved in the therapy success (predictors of result), we applied a regression model that included the following covariates: coming from the medical history: age, gender, and referred brace wear. The covariates from the clinical evaluation were as follows: height (in cm), weight (in kg), body mass index (BMI) (kg/sqm), angle trunk rotation (ATR), defined as hemithorax volume difference resulting from the vertebrae rotation assessed through the Bunnell scoliometer, aesthetic impact measured with the TRACE (Trunk Aesthetic Clinical Evaluation) score [ 31 ], and real brace wear (RBW) through the iButton device. Part of the covariates also came from radiographical data: Cobb angle, in-brace correction (IBC) (through in-brace X-rays taken after one month of brace wear).…”

Background: We need good outcome predictors to maximize the treatment efficiency of adolescents with idiopathic scoliosis (AIS). The in-brace correction has shown an important predictive effect on brace failure, while the influence of other variables is still debated. We aimed to identify new outcome predictors from a big prospective database of AIS. Methods: Design: Retrospective analysis of prospectively collected data. Inclusion criteria: AIS between 21 and 45°, Risser 0–2, brace prescription during the observation, treatment conclusion. All of the participants followed a personalized conservative approach according to the SOSORT Guidelines. Outcomes: End of growth below 30°–40°–50°. The regression model included age, BMI, Cobb angle, ATR, TRACE score, real brace wear (RBW), and in-brace correction (IBC). Results: A total of 1050 patients, 84% females, ages 12.1 ± 1.1, 28.2 ± 7.9° Cobb. IBC increased by 30%, 24%, and 23% the odds of ending treatment below 30°, 40°, and 50°, respectively. The OR did not change after the covariate adjustment. Cobb angle and ATR at the start also showed a predictive effect. Conclusions: The systematic evaluation of IBC in clinics is useful for individuating the patient response to brace treatment more accurately, even in relation to the Cobb angle and ATR degrees at the start. Further studies are needed to increase the knowledge on predictors of AIS treatment results.

“…The TRACE showed fair intra-rater and poor inter-rater reliability (14). Further Rasch analysis demonstrated that it can be used to compare the appearance of the trunk in different patient's groups (children and adolescents) with varying curve magnitudes before and after brace treatment (25).…”

Introduction. Aesthetic appearance is one of the major concerns in adolescent idiopathic scoliosis (AIS) patients and its improvement is one of the main treatment's goals. Poor trunk appearance is associated with reduced quality of life in adolescents with idiopathic scoliosis. Aim. To review instruments that have been created to evaluate poor trunk appearance in these children. Material and methods. PubMed database and the Consortium of Libraries of Serbia for Unified Acquisition - KoBSON were searched using the keywords "adolescent scoliosis", "aesthetic appearance", "evaluation" and "questionnaires". Results. In order to evaluate the aesthetic impairment in these patients, various instruments have been created. They can roughly be classed as instruments that assess subjective perception or objective aesthetic appearance. The first group consists primarily of self-administered quality of life questionnaires that include an aesthetic component, such as the Scoliosis Research Society 22 (SRS-22) questionnaire and the Italian Spinal Youth Quality of Life (ISYQoL) questionnaire, as well as visual scales based on patient-completed trunk drawings, such as the Walter Reed Assessment Scale, the Spinal Appearance Questionnaire, and the Trunk Appearance Perception Scale. Trunk asymmetry scales that use pictures, such as the TRACE (Trunk Aestethic Clinical Evaluation), the POTSI (Posterior Trunk Symmetry Index) and the ATSI (Anterior Trunk Symmetry Index), 2-dimensional digital photography, and surface topography can all be used to assess the aesthetic profile of subjects, allowing for objective evaluation. Conclusion. Each clinical examination should include a specific assessment of trunk asymmetry. Various instruments were developed with the goal of decreasing x-ray radiation exposure in these patients.

Purpose The study aims to assess if the angle of trunk rotation (ATR) in combination with other readily measurable clinical parameters allows for effective non-invasive scoliosis screening. Methods We analysed 10,813 patients (4–18 years old) who underwent clinical and radiological evaluation for scoliosis in a tertiary clinic specialised in spinal deformities. We considered as predictors ATR, Prominence (mm), visible asymmetry of the waist, scapulae and shoulders, familiarity, sex, BMI, age, menarche, and localisation of the curve. We implemented a Logistic Regression model to classify the Cobb angle of the major curve according to thresholds of 15, 20, 25, 30, and 40 degrees, by randomly splitting the dataset into 80–20% for training and testing, respectively. Results The model showed accuracies of 74, 81, 79, 79, and 84% for 15-, 20-, 25-, 30- and 40-degrees thresholds, respectively. For all the thresholds ATR, Prominence, and visible asymmetry of the waist were the top five most important variables for the prediction. Samples that were wrongly classified as negatives had always statistically significant (p ≪ 0.01) lower values of ATR and Prominence. This confirmed that these two parameters were very important for the correct classification of the Cobb angle. The model showed better performances than using the 5 and 7 degrees ATR thresholds to prescribe a radiological examination. Conclusions Machine-learning-based classification models have the potential to effectively improve the non-invasive screening for AIS. The results of the study constitute the basis for the development of easy-to-use tools enabling physicians to decide whether to prescribe radiographic imaging.
