STUDY DESIGN: In this prospective study, we measured the pad pressures of the Milwaukee brace in adolescent hyperkyphosis treatment. PURPOSE: We evaluated the skin-brace interface forces exerted by the main pads of the Milwaukee brace. OVERVIEW OF LITERATURE: A fundamental factor associated with brace effectiveness in spinal deformity is pad force adjustment. However, few studies have evaluated the in-brace force magnitude and its effect on curve correction. METHODS: Interface forces at four pads of the Milwaukee brace were measured in 73 patients withround back deformity (mean age, 14.04±1.97 years [range, 10–18]; mean initial Cobb angle,67.70°±9.23° [range, 50°–86°]). We used a modified aneroid sphygmomanometer to measure the shoulder and kyphosis pad pressures. Each patient underwent measurement in the standing and sitting positions during inhalation/exhalation. RESULTS: The mean pad pressures were significantly higher in the standing than in thesitting position, and significantly higher pressures were observed during inhalation compared toexhalation (p=0.001).There were no statistically significant differences between right and left shoulder pad pressures (p>0.05); however, the pressure differences between the right and left kyphosis pads were statistically significant (p<0.05). In a comparison of corrective forces with bracing for less or more than 6 months, corrective force was larger with bracing for less than 6 months (p=0.02). In the standing position, there were no statistically significant correlations between pad pressures and kyphosis curve correction. CONCLUSIONS: In the sitting position, there was a trend toward lower forces at the skin-brace interface; therefore, brace adjustment in the standing position may be useful and more effective. There was no significant correlation between the magnitude of the pad pressures and the degree of in-brace curve correction.

STUDY DESIGN: Retrospective study.PURPOSE: To evaluate the effect of bracing on spinopelvic rotation and psychosocial parameters in adolescents with idiopathic scoliosis (AIS).OVERVIEW OF LITERATURE: Complex three-dimensional deformity in AIS is proposed to influence the spinopelvic parameters and psychosocial condition in adolescents; however, few studies have quantitatively evaluated these parameters.METHODS: Thirty AIS who were prescribed a brace were included in the study. The patients’ standing postero-anterior and total spine radiographs were used to measure the primary curve Cobb angle, vertebral rotation, and pelvic rotation. Apical vertebral rotation (AVR), upper AVR, and lower AVR were measured using the Nash-Moe method. Pelvic rotation was determined using the left-to-right hemipelvic width ratio. The curve pattern was classified as per the Lenke classification system. In all, 14 patients had a type I curve, five had type II, six had type III, one had type IV, and four had type V curves. Brace compliance was subjectively evaluated by interviewing the patients and their parents. The health-related quality of life (HRQOL) and stress level of the recruited patients were assessed using the Brace Questionnaire and Bad Sobernheim Stress Questionnaire, respectively.RESULTS: The Cobb angle significantly decreased with at least 6 months of brace use. AVR correction changed significantly; however, no such results were observed for upper and lower AVR. Pelvic rotation and psychosocial parameters were not significantly affected by brace use. No statistically significant correlation was observed between brace compliance and curve correction.CONCLUSIONS: The Cobb angle and AVR are crucial measurements that help evaluate the treatment efficacy in AIS with small curves who undergo brace treatment. HRQOL and pelvic axial rotation are not influenced by the brace treatment.

STUDY DESIGN: This was a prospective cohort study.PURPOSE: This study aimed to evaluate the potential differences between the objective and subjective bracing compliances of adolescents with Scheuermann’s kyphosis.OVERVIEW OF LITERATURE: Bracing is a well-documented intervention for managing adolescents with progressive thoracic Scheuermann’s kyphosis, and the brace should be worn 23 hours every day. Most research studies that have investigated the efficacy of bracing have assumed that the patients wore the braces as advised or that the bracing time was measured subjectively. This may be one of the reasons for the conflicting reports regarding the efficacy of bracing.METHODS: Nineteen volunteers (11 girls and 7 boys, 12.89±1.77 years) who were prescribed Milwaukee braces for Scheuermann’s kyphosis were enrolled. Each brace was equipped with a miniature temperature logger to record the actual brace wearing time over a period of 3 weeks. The patients and their families were unaware of the mounted sensor. Each participants and/or parent was provided with a questionnaire to record the number of hours for which the brace was worn each day. In addition, the therapist asked each patient and/or his/her parent about the average number of hours that the brace was worn.RESULTS: The compliance rates measured using the temperature logger (16.00±4.90 hours daily) were significantly lower than those reported in the questionnaires (19.52±6.04 hours daily, p<0.001) and the verbal responses (20.21±6.05 hours daily, p<0.001). Moreover, there was no correlation of age, sex, and body mass index with brace compliance.CONCLUSIONS: The braces were worn less often than reported by the patients and/or their parents. Therefore, objective compliance assessments of adolescents with Scheuermann’s kyphosis in a brace are recommended for future studies.

The current study was carried out systematically by conducting a review of the literature. The purpose of this study was to conduct a systematic review of the literature to determine the effects of brace wearing on sagittal parameters in adolescents with idiopathic scoliosis (AIS). In this study, PubMed/MEDLINE (National Library of Medicine), Scopus, Ovid, CINAHL, PEDro, Google Scholar, and the Cochrane Library were accessed and searched using the patient, intervention, comparison, outcome, and study design model. We included studies that looked at the effects of brace treatment on sagittal spinopelvic parameters in AIS patients over the age of 18. The studies were chosen for their cross-sectional, retrospective, or prospective observational designs, and they were published in English. Review articles, case reports, case study designs, and conference abstracts were excluded from consideration. The methodological quality of the remaining articles was assessed using the Newcastle Ottawa Scale. A total of 12 studies were chosen, and 995 participants were evaluated, with 3 (25%) and 9 (75%) having high and moderate quality, respectively. The studies were classified based on the length of follow-up. Long-term, short-term, and immediate effects of brace wearing on sagittal spinopelvic parameters were reported in four, five, and three studies, respectively. The results of nine studies showed a significant decrease in Cobb angle after wearing the brace, which contradicted the findings of the other two. The cervical and sagittal pelvic parameters, thoracic kyphosis (TK), lumbar lordosis (LL), spinopelvic parameters, and sagittal balance were all evaluated in the intended studies, yielding varying results. According to the available literature, wearing a brace flattens the TK and LL. According to this systematic review, brace treatment may affect sagittal spinopelvic parameters in adolescents with AIS, particularly in TK and LL. The cervical and pelvic parameters yielded inconclusive results. This study backs up the idea that brace design and structure can influence sagittal parameter changes. The limitations of this study include different methods of parameter measurement, variations in the brace types and wear time, varying follow-up duration, and differences in participant characteristics.

Predictive clinical and radiological factors can potentially identify adolescent idiopathic scoliosis (AIS) most likely to benefit from overcorrection nighttime bracing. These factors can provide helpful information in clinical decision making. However, the relationship between these factors and outcomes of overcorrection nighttime bracing is unclear. This systematic review determined the predictive factors for identifying outcomes of overcorrection nighttime bracing in AIS. A systematic search was conducted on PubMed, MEDLINE, Scopus, and Embase from January 1986 to January 2021. Studies on AIS patients, aged 10–18 years, with a Risser sign of 0–2 and an initial Cobb angle of 20°–45°, who were treated with overcorrection nighttime bracing and for whom at least one predictive factor of treatment outcome (failure and/or success) was assessed were included. Two blinded reviewers independently evaluated the studies using a quality assessment tool. To determine predictive factors, the level of evidence was rated through best-evidence synthesis. A total of nine studies met the inclusion criteria. A Providence brace was used in six of the included studies, while a Charleston bending brace was used in three. Findings from two high-quality studies provided strong evidence of the association between curve flexibility and brace treatment success. In terms of the Risser sign, this evidence was obtained from three high-quality studies. Moderate evidence indicated a positive association between premenarchal status and nighttime bracing failure. Inconclusive evidence indicated that poor brace compliance is associated with treatment failure. Conflicting evidence of treatment failure was indicated for initial curve magnitude, curve type, in-brace correction, age, Risser sign, curve apex, and sex. These findings show that greater curve flexibility and a higher Risser sign are associated with overcorrection nighttime bracing success.

Routinely, adolescent idiopathic scoliosis (AIS) curves that progress beyond 40° in skeletally immature adolescents require surgery. However, some adolescents with AIS and their parents utterly refuse surgery and insist on wearing a brace. Debate continues regarding the appropriateness of bracing for AIS curves exceeding 40° in patients who have rejected surgical intervention. This systematic review and meta-analysis was conducted to review the literature on the effectiveness of bracing and its predictive factors in largermagnitude AIS curves ≥40°. This study replicated the search strategy used by the PICOS system for formulating study questions, which include consideration of the patient/population (P), intervention (I), comparison (C), outcome (O), and study design (S). The search was conducted up to January 2022 in the following bibliographic online databases only in the English language: PubMed, Google Scholar, Scopus, and Web of Science. Two assessors reviewed the articles for qualification. Eligible studies were assessed for risk of bias at the study level using the Newcastle-Ottawa Scale. The effect size across the studies was determined using standardized mean differences (Cohen’s d) and 95% confidence intervals for the meta-analysis. Among the eight included moderate quality studies, evidence of potential publication bias (p <0.05) for the trials included was found in the Cobb angle outcome. Results obtained through meta-analysis indicated that the effectiveness of bracing in controlling Cobb angle progression in curves ≥40° is significantly positive. Additionally, initial curve severity, Risser stage, in-brace curve correction, curve type, and apical vertebral rotation were considered risk factors associated with brace effectiveness. This systematic review revealed that bracing could alter the normal course of AIS curves ≥40° in patients refusing posterior spinal fusion (PSF). However, the suggested course for patients refusing PSF remains unclear because of the significant heterogeneity in the risk factors associated with bracing failure.

Methods: We evaluated the translation and back translation of the EOSQ-24 and made the required revisions as per the analysis performed by the expert committee and an international guideline to adapt it for use in this study. Thereafter, we recruited 100 EOS patients in order to evaluate its reliability and validity. The reliability was assessed with internal consistency. Convergent validity was assessed by comparing the scores of the EOSQ-24 and the 22-item Scoliosis Research Society Questionnaire (SRS-22r). Finally, the known groups validity was assessed as per patient’s sex, curve magnitude, and treatment type. Results: The Persian EOSQ-24 demonstrated very good internal consistency (Cronbach’s α=0.88). All the items had an acceptable corrected item-total correlation (>0.3). Further, the EOSQ-24 and the SRS-22r scores (p <0.001) were significantly correlated. The EOSQ-24 could discriminate patients with different curve magnitudes. Conclusions The Persian EOSQ-24 can serve as a disease-specific instrument with strong validity and reliability in the evaluation of EOS patients. Its applicability in other Persian-speaking countries and regions of the world needs to be investigated further.
