ABSTRACT
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.
ABSTRACT
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.
