Psychosocial Difficulties in Adolescent Idiopathic Scoliosis: Body Image, Eating Behaviors, and Mood Disorders

Strong support systems foster positive self-image in patients with scoliosis

PURPOSE

Friend support and social support have been suggested to be beneficial for adolescents facing medical challenges; however, there is little research to identify who is providing emotional support for children and adolescents with scoliosis. Therefore, the purpose of this study was to investigate the sources of emotional support and to analyze a program designed to encourage social support, the Scolios-us Mentor Program (Mentor Program).

METHODS

This study consisted of a cross-sectional survey. The survey included the SRS-22r, BSSQ-Brace, and questions about demographics, mental health, the Scolios-us Mentor Program, and general scoliosis experience. The survey was distributed via email to Mentor Program participants and to scoliosis clinicians to provide to their patients. Descriptive statistics, Mann-Whitney U tests, and correlations (Cochran-Armitage, Pearson's correlation, and Spearman's correlation) were used to analyze responses.

RESULTS

A total of 46 participants with an age range was 8-18 were included in the final analysis. The median current age was 13 (IQR: 3), and the median diagnosis age was 10 (IQR: 4). Our results indicate that most participants (76.1%) received emotional support from at least two sources, including family, friends, healthcare providers, and support groups. Participants with two or more support sources had significantly higher self-image scores than those below this threshold (p =.042). Self-image scores were significantly higher for those who reported receiving emotional support from a healthcare provider (p =.027). Over 60% (29/46) of participants participated in the Scolios-us Mentor Program. No significant differences were noted in BSSQ-Brace or SRS- 22r scores between those who participate in the Mentor Program versus those who do not, but mentees scored lower for function, self-image, and management than mentors. Interestingly, as program satisfaction increased, BSSQ-Brace scores decreased (p =.012).

CONCLUSIONS

Having a strong emotional support system is important for self-image in children and adolescents with scoliosis. Healthcare providers appear to play an important role in promoting a positive self-image in their scoliosis patients. To help patients foster a strong support system, healthcare providers should be knowledgeable of the available psychosocial resources, including scoliosis support groups, for children and adolescents with scoliosis.

Trunk endurance differences between female adolescents with and without idiopathic scoliosis

PURPOSE

This study compared trunk muscle endurance between female adolescents with idiopathic scoliosis (AIS) and non-AIS groups.

METHODS

This cross-sectional study included 91 females. Trunk muscle endurance was assessed using the Ito-Shirado and Biering-Sørensen tests. Anthropometric and radiographic data were collected. The Mann-Whitney U test compared endurance and abdominal-to-paraspinal endurance ratio between groups. Spearman's correlation assessed relationships between endurance and participant characteristics.

RESULTS

The AIS group's performance on the Ito-Shirado and Biering-Sørensen tests was 57% and 68% of the non-AIS group's test durations, respectively (p = 0.001). However, there was no significant difference in the abdominal-to-paraspinal endurance ratio between the two groups (p = 0.7). Additionally, a low negative correlation was observed between paraspinal muscle endurance and both weight (rho = - 0.29, p = 0.006)) and BMI (rho = - 0.3, p = 0.005) in the AIS group, while abdominal endurance correlated negatively with height (rho = - 0.25, p = 001).

DISCUSSION

Females with AIS exhibit significantly reduced endurance in both paraspinal and abdominal muscles compared to healthy controls, despite maintaining a similar abdominal-to-paraspinal endurance ratio. The findings suggest the need for trunk muscle endurance evaluation and training in rehabilitation programs for individuals with AIS.

Sex and age differences in depression and anxiety networks among adolescents with idiopathic scoliosis: A network analysis

BACKGROUND

Depression and anxiety are prevalent psychological challenges among patients with adolescent idiopathic scoliosis (AIS), affecting individuals across both sex and age groups.

AIM

To explore the network structure of depression and anxiety symptoms, with a focus on identifying differences at the symptom level between sex and age subgroups.

METHODS

A total of 1955 participants diagnosed with AIS aged 10-18 years were assessed using the Patient Health Questionnaire Depression Scale (PHO-9) and the Generalized Anxiety Disorder Scale (GAD-7), and 765 patients exhibiting PHQ-9 or GAD-7 scores ≥ 5 were enrolled in our study. Network analysis and network comparison tests were utilized to construct and compare the depression-anxiety symptoms networks among sex and age subgroups.

RESULTS

The results revealed GAD3 "Excessive worry" and PHQ2 "Sad mood" were the most significant central symptoms in all subgroups, while "Sad mood" had higher strength than "Excessive worry" in the lower age group. In the network comparisons, the female network exhibited tighter connectivity, especially on GAD6 "Irritability" and GAD2 "Uncontrollable worry", while only PHQ3 "Sleep" and PHQ9 "Suicidal ideation" had differences at the local level in the lower age group.

CONCLUSION

Several interventions targeting excessive worry and sad mood could reduce the risk of depression and anxiety symptoms in the AIS population. Furthermore, specific anxiety symptoms in females, along with sleep disturbances and suicidal ideation in the lower age group, should be addressed at an early stage to prevent significant disruptions in mental health trajectories.

Is the information provided by large language models valid in educating patients about adolescent idiopathic scoliosis? An evaluation of content, clarity, and empathy : The perspective of the European Spine Study Group

PURPOSE

Large language models (LLM) have the potential to bridge knowledge gaps in patient education and enrich patient-surgeon interactions. This study evaluated three chatbots for delivering empathetic and precise adolescent idiopathic scoliosis (AIS) related information and management advice. Specifically, we assessed the accuracy, clarity, and relevance of the information provided, aiming to determine the effectiveness of LLMs in addressing common patient queries and enhancing their understanding of AIS.

METHODS

We sourced 20 webpages for the top frequently asked questions (FAQs) about AIS and formulated 10 critical questions based on them. Three advanced LLMs-ChatGPT 3.5, ChatGPT 4.0, and Google Bard-were selected to answer these questions, with responses limited to 200 words. The LLMs' responses were evaluated by a blinded group of experienced deformity surgeons (members of the European Spine Study Group) from seven European spine centers. A pre-established 4-level rating system from excellent to unsatisfactory was used with a further rating for clarity, comprehensiveness, and empathy on the 5-point Likert scale. If not rated 'excellent', the raters were asked to report the reasons for their decision for each question. Lastly, raters were asked for their opinion towards AI in healthcare in general in six questions.

RESULTS

The responses among all LLMs were 'excellent' in 26% of responses, with ChatGPT-4.0 leading (39%), followed by Bard (17%). ChatGPT-4.0 was rated superior to Bard and ChatGPT 3.5 (p = 0.003). Discrepancies among raters were significant (p < 0.0001), questioning inter-rater reliability. No substantial differences were noted in answer distribution by question (p = 0.43). The answers on diagnosis (Q2) and causes (Q4) of AIS were top-rated. The most dissatisfaction was seen in the answers regarding definitions (Q1) and long-term results (Q7). Exhaustiveness, clarity, empathy, and length of the answers were positively rated (> 3.0 on 5.0) and did not demonstrate any differences among LLMs. However, GPT-3.5 struggled with language suitability and empathy, while Bard's responses were overly detailed and less empathetic. Overall, raters found that 9% of answers were off-topic and 22% contained clear mistakes.

CONCLUSION

Our study offers crucial insights into the strengths and weaknesses of current LLMs in AIS patient and parent education, highlighting the promise of advancements like ChatGPT-4.o and Gemini alongside the need for continuous improvement in empathy, contextual understanding, and language appropriateness.

Patient-Reported Mental Health and Quality of Life in Pediatric Adolescent Idiopathic Scoliosis Patients

Adolescent idiopathic scoliosis (AIS) is a prevalent spinal deformity that can affect patients' mental health and overall quality of life. Orthopaedic providers commonly employ questionnaires such as the (scoliosis research society) SRS-22, PROMIS, and pediatric/s quality of life, among others, to assess patient-reported outcomes, including pain interference, depressive symptoms, and self-image. This article aims to examine the effect of various AIS treatments on patients' mental health and health-related quality of life (HRQoL), while also discussing the utility of these questionnaires in clinical research. The reviewed studies consistently demonstrate that treatment may influence patients' mental health, emphasizing the vital role of questionnaires in measuring mental health and HRQoL throughout their treatment journey. Furthermore, these instruments enable healthcare providers to implement strategies that enhance patients' mental well being as part of their treatment plans. AIS poses a risk factor for poor mental health and HRQoL. However, further research is warranted to determine the longitudinal effect of AIS on mental health and HRQoL. These investigations will empower healthcare providers to identify optimal treatment plans, thereby alleviating the burden on the mental health and HRQoL of AIS patients.

Advances in 3D correction of adolescent scoliosis: The superiority of scoliocorrector fatma-UI in rotational realignment

This letter compares the clinical efficacy and economic feasibility of the scoliocorrector fatma-UI (SCFUI) with direct vertebral rotation (DVR) in treating adolescent idiopathic scoliosis (AIS). SCFUI has shown promising results in three-dimensional spinal correction, providing superior rotational alignment compared to DVR and achieving significant improvements in coronal and sagittal planes. Additionally, SCFUI's advanced design reduces risks associated with AIS surgeries and enhances overall patient outcomes. Economic analysis reveals SCFUI as a cost-effective option, potentially lowering long-term healthcare costs by minimizing complications and revisions. Our findings suggest that SCFUI is a viable, innovative approach in AIS treatment, meeting clinical and economic demands in orthopedic care.

Genetics and pathogenesis of scoliosis

Background

Scoliosis is defined as a lateral spine curvature of at least 10° with vertebral rotation, as seen on a posterior-anterior radiograph, often accompanied by reduced thoracic kyphosis. Scoliosis affects all age groups: idiopathic scoliosis is the most common spinal disorder in children and adolescents, while adult degenerative scoliosis typically affects individuals over fifty. In the United States, approximately 3 million new cases of scoliosis are diagnosed annually, with a predicted increase in part due to global aging. Despite its prevalence, the etiopathogenesis of scoliosis remains unclear.

Methods

This comprehensive review analyzes the literature on the etiopathogenetic evidence for both idiopathic and adult degenerative scoliosis. PubMed and Google Scholar databases were searched for studies on the genetic factors and etiopathogenetic mechanisms of scoliosis development and progression, with the search limited to articles in English.

Results

For idiopathic scoliosis, genetic factors are categorized into three groups: genes associated with susceptibility, disease progression, and both. We identify gene groups related to different biological processes and explore multifaceted pathogenesis of idiopathic scoliosis, including evolutionary adaptations to bipedalism and developmental and homeostatic spinal aberrations. For adult degenerative scoliosis, we segregate genetic and pathogenic evidence into categories of angiogenesis and inflammation, extracellular matrix degradation, neural associations, and hormonal influences. Finally, we compare findings in idiopathic scoliosis and adult degenerative scoliosis, discuss current limitations in scoliosis research, propose a new model for scoliosis etiopathogenesis, and highlight promising areas for future studies.

Conclusions

Scoliosis is a complex, multifaceted disease with largely enigmatic origins and mechanisms of progression, keeping it under continuous scientific scrutiny.

The societal burden associated with adolescent idiopathic scoliosis: a cross-sectional burden-of-disease study

BACKGROUND

In the general population the prevalence of adolescent idiopathic scoliosis (AIS) is 2-3%. There is growing awareness of how AIS affects the quality of life of patients. However, the extent of the societal burden AIS poses remains poorly understood. Therefore, this study aimed to determine the societal burden of AIS.

METHODS

A cross-sectional burden of disease study was conducted using a bottom-up, prevalence-based approach. Patients with AIS or guardians of a child diagnosed with AIS residing in the Netherlands were eligible for inclusion. The survey was distributed between June - December 2022 and was completed once by each participant. Costs were assessed using the institute for Medical Technology Assessment - Medical Consumption and Productivity Cost Questionnaires. The health-related quality of life (HRQoL) was assessed using the EuroQol 5D-5L/EuroQol 5D Youth and the Scoliosis Research Society-22 revised questionnaires. Costs and HRQoL were identified, measured, and valued.

RESULTS

Participants (n = 229) were predominantly female (92%), on average 35 years old, and were employed (65%). The societal cost for a patient with AIS in the Netherlands was €12,275 per year. The largest costs were estimated for the healthcare and productivity losses. The mean utility score for adults was 0.7 (SD 0.20). Severe pain was experienced by 10% of the adult participants and 44% reported to experience moderate pain/discomfort. Statistically significant differences between different age groups were present for the sector costs and HRQoL.

CONCLUSIONS

AIS negatively impacts societal costs and the HRQoL. Reducing the burden that is posed on the productivity sector by AIS and further improving the HRQoL for AIS patients is needed.

Evaluating the prevalence of psychiatric comorbidities associated with pediatric scoliosis utilizing ResearchMatch

PURPOSE

The goal of this study is to characterize the self-reported prevalence of psychiatric comorbidities among patients with adolescent scoliosis.

METHODS

Eligible patients across the US were surveyed using ResearchMatch, a validated online platform. The survey collected patient demographics, type of scoliosis, scoliosis treatment received, and the mental health diagnoses and interventions.

RESULTS

Nearly all (98%) of the 162 respondents were patients themselves, the remainder of which were parents. The majority of whom were female (93%), Caucasian (85%), and diagnosed with idiopathic scoliosis (63%). The median age of diagnosis was 13 (IQR 11-18). Most respondents had mild to moderate scoliosis (65%), and 17% received surgical treatment. 76 of 158 (48%) responded that scoliosis affected their overall mental health, and 92 (58%) had received a mental health diagnosis-76% were diagnosed after their scoliosis diagnosis. Of the 92 with mental health diagnoses, the most common diagnoses were clinical depression (83%), anxiety (71%), negative body image (62%). Over 80% of patients received medical treatment or therapy. Of those with depression, 38.4% received counseling and 45.2% received medication. 52% of the respondents also had immediate family members with mental health diagnoses, with siblings (48%) having the highest proportion.

CONCLUSION

According to the CDC, the prevalence of US teenagers with diagnosed depression was found to be 3.9% and anxiety disorder to be 4.7%, notably higher among adolescent girls. In this national sample, over half of adolescent scoliosis patients report psychiatric comorbidity, often diagnosed years later. The most prevalent psychiatric condition is depression, anxiety, and body-image disturbances. These findings highlight the importance of awareness of the psychiatric impact of adolescent scoliosis, and importance of screening and treatment of comorbid mental health conditions.

The diagnostic accuracy of community spine radiology for adolescent idiopathic scoliosis brace candidates

PURPOSE

The study aims to establish the diagnostic accuracy of community spine x-rays for brace candidates.

METHODS

A review of adolescent idiopathic scoliosis patients seen for initial visit at a tertiary care pediatric hospital was conducted (n = 170). The index test was the pre-referral community spine x-ray interpreted by a community radiologist. Measures of diagnostic accuracy for the index test were determined against the reference standard if images were obtained within 90 days (n = 111). The reference standard was the 3-foot standing EOS spine x-ray evaluated by spine specialists. Diagnostic criterion for a brace candidate was dichotomized by Cobb angle range (25-40°) according to Scoliosis Research Society criteria. Risser stage was not included given significant missing data in index reports. To mitigate the uncertainty around true progression, sensitivity analyses were conducted on a sub-sample of data when index test was within 60 days of the reference standard (n = 67).

RESULTS

Accuracy of the community spine x-ray to detect a brace candidate was 65.8% (95% CI 56.2-74.5). Sensitivity of the index test was 65.4% with a false negative rate of 34.6%. Specificity was 66.1% with a false positive rate of 33.9%. Positive and negative predictive values were 63.0% and 68.4%, respectively. Of the total number of brace candidates (n = 52), 32.7% were missed because of underestimation in Cobb angle (95% CI 21.5-46.2). The proportion of missed brace candidates because of underestimation was unchanged with 60-day data (p = 0.37).

CONCLUSIONS

Inaccuracies in community spine radiology may lead to missed opportunities for non-operative treatment.

Association between Adverse Psychological Emotions and Postoperative Brace for Adolescent Idiopathic Scoliosis: A Prospective Cohort Study with Propensity Score Matching

OBJECTIVE

Although the advantages of postoperative braces have been verified in many fields, it is not clear whether postoperative braces can help reduce patients' adverse psychological emotions such as kinesiophobia, anxiety, and depression. This study aims to analyze whether the use of a postoperative brace helps reduce adverse psychological emotions in adolescent idiopathic scoliosis (AIS) patients undergoing spinal deformity surgeries.

METHODS

All consecutive patients who underwent spinal corrective surgeries at our institution between April 2023 and July 2023 formed the prospective cohort. Outcome measures were collected in the preoperative period, 3 months after surgery, and 6 months after surgery. All patients were assessed using the Tampa scale for kinesiophobia (TSK), the hospital anxiety and depression scale (HADS), and the numerical rating scale (NRS). A statistical model of propensity score matching was used to eliminate potential selection bias and maintain comparability. Multivariate linear regression models were used to determine the relationship between postoperative brace and adverse psychological emotions.

RESULTS

After propensity score matching, this study ultimately enrolled 150 patients. There were no significant differences between the two groups in terms of demographic and perioperative variables. The fully adjusted model showed that the TSK scores of the non-brace group at the 3-month (ꞵ = 2.50, 95% CI 0.80-4.20, p = 0.005) and 6-month follow-up (ꞵ = 2.75, 95% CI 0.75-4.74, p = 0.007) were significantly higher than those of the brace group. The HADS score of the non-brace group at the 3-month follow-up was significantly higher than that of the brace group (ꞵ = 1.75, 95% CI 0.28-3.22, p = 0.019). The NRS score of the non-brace group at the 3-month follow-up was significantly higher than that of the brace group (ꞵ = 0.69, 95% CI 0.05-1.33, p = 0.034). At the 6-month follow-up, there were no significant difference for HADS score or NRS score between the two groups.

CONCLUSION

In the early postoperative period, the postoperative brace could provide AIS patients with psychological supports and help them reduce the frequency of adverse psychological emotions. The postoperative brace could continuously improve the fear of movement within 6 months after surgery, and help reduce anxiety, depression, and pain within 3 months after surgery.

Pelvic rotation correction combined with Schroth exercises for pelvic and spinal deformities in mild adolescent idiopathic scoliosis: A randomized controlled trial

INTRODUCTION

Individualized treatment of spinal deformity is needed for adolescent idiopathic scoliosis (AIS), and the integration of pelvic rotation correction based on proprioceptive neuromuscular facilitation (PNF) into regular physiotherapy may be a promising approach. However, few high-quality studies have investigated its effects. This study aimed to evaluate the efficacy of pelvic rotation correction combined with Schroth exercises in the treatment of mild AIS.

METHODS

This was a randomized controlled trial. Forty-two AIS patients were randomly divided into experimental and control groups. Both groups underwent 20 therapeutic sessions over 24 weeks. All patients (n = 42) performed Schroth exercises at each session. In addition, the experimental group (n = 21) also participated in a pelvic rotation correction program based on PNF at each session. The primary outcome was the concave/convex ratio of hipbone widths, and the secondary outcomes included the Cobb angle, trunk rotation angle, self-perception, apical vertebral translation, and apical vertebral rotation. Patients were evaluated before and after 24 weeks of intervention.

RESULTS

There was a significant between-group difference in the change from baseline between the experimental and control groups for the following parameters: concave/convex ratio 2.89% (95% confidence interval [CI], 1.58 to 4.20, P<0.001), trunk rotation angle -1.26° (95% CI, -2.20 to -0.32; P = 0.01), and apical vertebral rotation improved by at least one class from baseline in 3 patients (14.3%) in the control group and 9 patients (42.9%) in the experimental group (P = 0.04). While Cobb angle -1.60° (95% CI, -7.75 to 0.54; P = 0.14), self-image 0.149 (95% CI, 0.001 to 0.297; P = 0.049), apical vertebral translation -0.58 mm (95% CI, -3.83 to 2.67; P = 0.72), and pelvic obliquity 0.10° (95% CI, -0.21 to 0.41; P = 0.52) did not differ significantly.

CONCLUSIONS

Pelvic rotation correction combined with Schroth exercises more effectively improved pelvic axial rotation and other spinal deformities, including trunk rotation and apical vertebral rotation, than Schroth exercises alone in the treatment of mild AIS.

Distribution of scoliosis in 2.22 million adolescents in mainland China: A population-wide analysis

Background

The characteristics of scoliosis afflicting school children and adolescents in mainland China are still unclear. Therefore, we conducted a systematic review to estimate scoliosis's prevalence and characterise its distribution in China.

Methods

We screened PubMed, Scopus, WanFang, China National Knowledge Infrastructure, National Science and Technology Library, and WeiPu databases for mainland China articles published between 1 January 1980 and 31 October 2022. Among them, we identified population-wide scoliosis studies in school children and adolescents. The main outcomes were the positive rate of primary screening and the prevalence of final screening. Primary screening mainly included general examination with/without the forward bending test in school. The final screening entailed clinical diagnosis by Röntgen radiation in a hospital (based on primary screening). A meta-analysis of scoliosis distribution by gender was performed to calculate the odds ratios (ORs) and 95% confidence intervals (CIs). Further, we analysed the distributions of scoliosis by age, region, aetiological type, and severity of curvature, in addition to the correlation between its prevalence and altitude or latitude.

Results

77 studies with 2 224 320 participants were included. The positive rate through primary screening was 3.97%, whereas the prevalence of scoliosis at final screening was 1.20%. Analysing the data revealed a higher prevalence of scoliosis in girls (OR = 1.57; 95% CI = 1.38-1.81). The age-wise peak rate of scoliosis was 15-16 years (1.07%) in boys and 13-14 years (1.42%) in girls. The mean prevalence of scoliosis was 1.07% in the western region, 1.54% in the central, and 1.35% in the eastern. Scoliosis prevalence was not correlated with either altitude or latitude. The prevalence of idiopathic and congenital scoliosis was 1.18 and 0.03%. Among all subjects with scoliosis, 79.10 and 16.80% had mild and medium disease severity.

Conclusions

According to this comprehensive study using data sets of scoliosis in adolescents across mainland China, the mean prevalence of scoliosis is 1.20%, yet 1.57 times higher in girls than boys, and is most prevalent in the middle region. Overall, scoliosis in adolescents could pose a burden to public health in mainland China.

The Superiority of Schroth Exercise Combined Brace Treatment for Mild-to-Moderate Adolescent Idiopathic Scoliosis: A Systematic Review and Network Meta-Analysis

OBJECTIVE

The current study aimed to assess and rank the comparative efficacy of different nonoperative treatments on Cobb angle, angle of trunk rotation, and quality of life for mild-to-moderate adolescent idiopathic scoliosis.

METHODS

A comprehensive search of databases, including Medline, The Cochrane Library, PubMed, EMBASE, and Web of Science spanning all previous years up to January 1, 2024. The included studies were evaluated for literature quality according to Cochrane Handbook criteria, and a network meta-analysis was performed using STATA 14.0 statistical software.

RESULTS

Twenty randomized controlled trials met all inclusion criteria and were analyzed. Schroth exercise and scoliosis-specific exercise combined with brace treatments had a significant positive effect on Cobb angle and quality of life. For angle of trunk rotation, Schroth exercise and Schroth exercise combined with brace treatments prove more effective compared to the control group. On surface-under-the-cumulative-ranking-curve analysis, Schroth exercise combined with brace treatment had the highest likelihood for reducing Cobb angle (P-score = 0.899), angle of trunk rotation (0.82), and improving quality of life (0.828).

CONCLUSIONS

Although most conservative treatments had benefits for mild-to-moderate adolescent idiopathic scoliosis, the most optimal programs were those that included (1) at least 10 weeks of approximately 60-minute Schroth exercise sessions twice a week and (2) wearing the brace for 23 hours every day throughout the treatment period.

Reliability and Validity of the Adapted Chinese Version of the Quality of Life Profile for Spine Deformities in Adolescents With Idiopathic Scoliosis

STUDY DESIGN

Retrospective cohort study.

OBJECTIVE

To evaluate the cross-cultural adaptability and internal consistency of the Chinese version of the Quality-of-Life Profile for Spine Deformities (QLPSD) questionnaire in mainland China.

METHODS

The original QLPSD was translated from Spanish into Chinese with proper cross-cultural adaptation based on the American Academy of Orthopaedic Surgeons guidelines. A total of 129 AIS patients referring to our institution from February 2021 to January 2022 were enrolled in this study. The effects of ceiling and floor were evaluated and the reliability was verified by examining the internal consistency (the Cronbach's α coefficient). Interclass Correlation Coefficient (ICC) was used to test and retest reliability. The C-QLPSD dimensions were compared with the domains in Chinese version of 36-Item Short Form Health Survey (SF-36) and Scoliosis Research Society-22 (SRS-22) questionnaires using Pearson correlation coefficient to assess the concurrent validity.

RESULTS

No significant floor and ceiling effects in C-QLPSD was observed. The total Cronbach's α was estimated at .914, ranging from .768 in back pain dimensions to .862 in psychosocial function dimensions. The C-QLPSD dimensions indicated satisfactory test-retest reliability with ICC range of .784-.870. Construct validity analysis revealed that C-QLPSD was well correlated with SRS-22 and SF-36. The values of total correlation coefficient were calculated at -.924 and -.871, respectively, which were both statistically significant (P < .05).

CONCLUSION

The adapted Chinese version of QLPSD had good internal consistency and excellent test-retest reliability, which can be used to assess the outcome among Chinese-speaking patients with adolescent idiopathic scoliosis.

Association of Functional Gastrointestinal Disorders with Adolescent Idiopathic Scoliosis

Numerous adolescents diagnosed with adolescent idiopathic scoliosis (AIS) often manifest symptoms indicative of functional gastrointestinal disorders (FGIDs). However, the precise connection between FGIDs and AIS remains unclear. The study involved adolescents drawn from sample datasets provided by the Korean Health Insurance Review and Assessment Service spanning from 2012 to 2016, with a median dataset size of 1,446,632 patients. The AIS group consisted of individuals aged 10 to 19 with diagnostic codes for AIS, while the control group consisted of those without AIS diagnostic codes. The median prevalence of FGIDs in adolescents with AIS from 2012 to 2016 was 24%. When accounting for confounding factors, the analysis revealed that adolescents with AIS were consistently more prone to experiencing FGIDs each year (2012: adjusted odds ratio (aOR), 1.21 [95% confidence interval (CI), 1.10-1.35], p < 0.001; 2013: aOR, 1.31 [95% CI, 1.18-1.46], p < 0.001; 2014: aOR, 1.24 [95% CI, 1.12-1.38], p < 0.001; 2015: aOR, 1.34 [95% CI, 1.21-1.49], p < 0.001; and 2016: aOR, 1.35 [95% CI, 1.21-1.50], p < 0.001). These findings suggest that AIS is correlated with an elevated likelihood of FGIDs, indicating that AIS may function as a potential risk factor for these gastrointestinal issues. Consequently, it is recommended to provide counseling to adolescents with AIS, alerting them to the heightened probability of experiencing chronic gastrointestinal symptoms.

Pain Medication Use Two Years After Adolescent Idiopathic Scoliosis Fusion Surgery

STUDY DESIGN

Observational case control.

OBJECTIVE

The objective of this study was to evaluate the prevalence of opioid use two years after surgical correction of adolescent idiopathic scoliosis (AIS) and its association with preoperative mental health.

SUMMARY OF BACKGROUND DATA

Studies of opiate use have reported that up to 80% of users began their addiction with misuse of prescription opioids. Identifying opioid use and those at risk in the AIS population is critical for optimal outcomes.

MATERIALS AND METHODS

A query of a multicenter prospective AIS surgical fusion registry was performed to identify patients of all curve types with responses to question 11 on the Scoliosis Research Society-22 questionnaire at two years postoperative. Question 11 asks about pain medication usage for the patient's back with five specific responses: narcotics daily, narcotics weekly or less, non-narcotics daily, non-narcotics weekly/less, or none. Ordinal regression was used to evaluate the association between preoperative Scoliosis Research Society-22 Mental Health (MH) domain scores and two-year postoperative pain medication usage.

RESULTS

A total of 2595 patients who underwent surgery from 2002 to 2019 met inclusion. The average primary curve was 56±12°, average age 14.7±3 years, and 81.5% were female. Forty (1.5%) patients reported utilizing opioids two years after surgery, and a significant difference in preoperative MH scores was observed. Patients taking daily opioids postoperatively had the lowest median preoperative MH score (3.75), followed by non-narcotic group (4), and no medication (4.2, P <0.001). Three patients reporting opioid use postoperatively reported preoperative usage. The rate of two-year postoperative medication use based on the year of surgery demonstrated a small linear decrease in opioid use over time, with a slight increase in nonopioid daily use.

CONCLUSIONS

Less than 2% of patients reported taking opioids for back pain two years after surgical correction of AIS. A lower MH score before surgery may place a patient at increased risk for opioid use two years after surgery. An analysis of the year of surgery suggests that changes in prescription practices over time may be occurring.

The Role of Muscle Biomarkers in Adolescent Idiopathic Scoliosis

Adolescent idiopathic scoliosis (AIS) is the predominant orthopedic disorder in children, affecting 1-3% of the global population. Research in this field has tried to delineate the genetic factors behind scoliosis and its association with heredity since AIS is considered a polygenic disease and has different genetic and epigenetic factors. The current study conducted a narrative review of the literature, focusing on biomarkers in the pathophysiology of muscle in AIS patients. Articles were collected from Scopus, Pubmed, and Web of Science. The key screening parameters were scoliosis classification, sampling, and the biomarkers evaluated. This review emphasizes potential key mechanisms and molecular regulators in muscle tissue. While there has been limited focus on the proteins contributing to muscle changes in AIS, significant attention has been given to genomic studies of single-nucleotide polymorphisms, particularly in LBX1. Despite these efforts, the exact causes of AIS remain elusive, with several theories suggesting genetic and hormonal factors. This review identified critical protein biomarkers such as Gi-protein alpha subunits, fibrillin-1 and -2, and various differentially expressed proteins, which may be linked to muscle alterations in AIS. This field of research is still limited due to a lack of homogeneity in the distinction of patients by groups and curve severity. Although the pathophysiology of AIS is still unclear, molecular research is important to guide the treatment of AIS before achieving skeletal maturity, thus avoiding serious problems associated with posture changes and low quality of life. In the future, a more comprehensive synergy between orthopedic and molecular research might ameliorate the diagnosis and treatment of AIS patients.

Psychosocial Effect of Brace Treatment in Adolescent Idiopathic Scoliosis: A Study Using EQ-5D

STUDY DESIGN

Retrospective cohort study.

OBJECTIVE

To evaluate psychosocial effect of brace treatment in adolescent idiopathic scoliosis (AIS) using EuroQoL 5-dimension (EQ-5D) depression and anxiety category.

BACKGROUND

AIS is a structural abnormality of the spine often affecting patients during the puberty, a critical period of developing psychosocial problems. Many questionnaires had been adapted to evaluate mental health and health-related quality of life of AIS patients. However, these questionnaires are often time consuming and difficult to obtain. Therefore, a simpler substitute-EQ-5D-was evaluated.

METHODS

This is a single-center retrospective cohort analysis of adult idiopathic scoliosis patients aged between 8 and 19, visiting outpatient's clinic. Beck's depression inventory, EQ-5D and EuroQoL visual assessment scale, and Objectified Body Consciousness Scale for Youth were compared between brace group and non-brace group of AIS patients. Furthermore, difference between male and female were evaluated within brace group.

RESULTS

None of the questionnaire showed significant difference between brace and non-brace group. However, when male and female patients were compared within brace group, female patients were significantly more susceptible to depression and anxiety based on EQ-5D and body consciousness. Furthermore, depression and anxiety according to both BDI and EQ-5D were significantly correlated to health-related quality of life.

CONCLUSION

During brace treatment of female AIS patients, psychosocial status played a significant role in health-related quality of life. EQ-5D is a simple way to monitor the mental health status.

Body-Related Attentional Bias in Adolescents Affected by Idiopathic Scoliosis

Attentional biases toward body-related information increase body dissatisfaction. This can lead at-risk populations to develop psychopathologies. This phenomenon has not been extensively studied in girls affected by idiopathic scoliosis. This work aimed to study the cognitive processes that could contribute to the worsening and maintaining of body image disorders in adolescent idiopathic scoliosis. Twenty-eight girls were recruited and tested for body image dissatisfaction through the Scoliosis-Research-Society-22-revised (SRS-22r) questionnaire. Attentional biases towards disease-related body parts were assessed using a computerized visual match-to-sample task: girls were asked to answer as fast and accurately as possible to find the picture matching a target by pressing a button on a computer keyboard. Reaction times (RTs) and accuracy were collected as outcome variables and compared within and between groups and conditions. Lower scores in SRS-22r self-image, function, and total score were observed in scoliosis compared to the control group (p-value < 0.01). Faster response times (p-value = 0.02) and higher accuracy (p-value = 0.02) were detected in the scoliosis group when processing shoulders and backs (i.e., disease-relevant body parts). A self-body advantage effect emerged in the scoliosis group, showing higher accuracy when answering self-body stimuli compared to others' bodies stimuli (p-value = 0.04). These results provide evidence of body image dissatisfaction and attentional bias towards disease-relevant body parts in girls with scoliosis, requiring clinical attention as highly predisposing to psychopathologies.

Translation, reliability and validity of the Turkish version of Scoliosis Japanese Questionnaire-27 in adolescent idiopathic scoliosis

PURPOSE

Disease-specific scales which evaluate QoL are needed to evaluate treatment outcomes, and to compare the effects of different treatments. The outcome measures evaluating quality of life in adolescent idiopathic scoliosis are limited. The purpose of this study was to examine the validity and reliability of the Turkish version of the Scoliosis Japanese Questionnaire-27 (SJ-27) in adolescent idiopathic scoliosis.

METHODS

The SJ-27 questionnaire was translated into Turkish and 61 female patients filled out the translated version (TRv.SJ-27) twice to measure the test-retest reliability of the scale. Internal reliability of the questionnaire was estimated using Cronbach's α coefficient. The intraclass correlation coefficient was analysed for each item. Discriminant validity and convergent validity were determined by correlations with Cobb angle, ATR and the SRS-22r scale.

RESULTS

The mean Cobb angle was 25.8° and the ATR angle was 8.8°. Cronbach's α value was estimated as 0.935. The test-retest correlation coefficient for the item-total score was 0.877 (p = 0.000). Validity analysis showed a significantly positive correlation between the TRv.SJ-27 total score and Cobb and ATR angles, and a significantly negative relationship was found between the TRv.SJ-27 and SRS-22r scores.

CONCLUSIONS

It would be useful to use different outcome measures to assess the scoliosis-specific quality of life in clinical practice and research. The findings suggest that the Turkish version of Scoliosis Japanese Questionnaire-27 is a valid and reliable measure to assess Turkish patients with AIS.

#Scoliosis: an analysis of patient perception of scoliosis on TikTok

Background

Social media presents an opportunity to analyze popular opinion about patient experiences. Idiopathic scoliosis is a spinal pathology commonly identified in younger patients who are the largest users of social media.

Objective

To analyze posts on the social media platform, TikTok, to better understand the scoliotic patient condition.

Methods

TikTok posts were searched manually by screening for "#Scoliosis." Variables assessed included number of likes, conveyed tone, gender, activities of daily living, incisional scar, imaging, involved spine level, spinal curvature, pain, formal physical therapy, multiple operations/reoperation, brace use, self-image, mobility, and educational/awareness posts. Number of responses per category were evaluated for the total they represented and the percentage of available posts containing those elements. Odds ratios with 95% confidence intervals were calculated for each collected variable.

Results

More posts were positive than negative (P < 0.001) and from female users than male users (P < 0.001). Self-image was the most prevalent subject, with many posts not mentioning activities of daily living, incisional scars, imaging, pain, physical therapy, timing, awareness/education, or involved spine levels.

Conclusions

More females post about scoliosis than males, with most posts containing positive self-image-related themes. This may represent a positive public attitude about scoliosis; however, further research is needed.

Functional Characterization of Novel Lunatic Fringe Variants in Spondylocostal Dysostosis Type-III with Scoliosis

Scoliosis affects over four million Americans, with most cases having an idiopathic cause. Pathogenic variants in the LUNATIC FRINGE (LFNG) gene can cause spondylocostal dysostosis type-III (SCD3), which is a rare skeletal dysplasia characterized by the absence, fusion, or partial development of vertebrae and ribs. Acute restrictive lung disease and scoliosis may also be present in some cases. The variability in symptoms suggests that there may be other underlying pathological mechanisms that are yet to be discovered. We conducted an analysis of two novel LFNG variants, c.766G>A (p.G256S) and c.521G>A (p.R174H), that were observed in a patient with SCD3 phenotype and scoliosis. Characterizing these variants can help us better understand the relationship between genotype and phenotype. We assessed both variants for impaired glycosyltransferase activity, subcellular mislocalization, and aberrant pre-proprotein processing. Our results indicate that the p.G256S variant is enzymatically nonfunctional, while the p.R174H variant is functionally less effective. Both variants were correctly localized and processed. Our findings suggest that the hypomorphic variant (p.R174H) may have partially improved the patient's stature, as evidenced by a lower arm span-to-height ratio, increased height, and more vertebrae. However, this variant did not appear to have any effect on the severity of vertebral malformations, including scoliosis. Further research is necessary to determine the extent to which variations in LFNG activity affect the presentation of SCD3.

The economic and societal burden associated with adolescent idiopathic scoliosis: A burden-of-disease study protocol

Background

Adolescent idiopathic scoliosis (AIS) has an estimated general population prevalence of 2% to 3%. The impact of adolescent idiopathic scoliosis (AIS) on the patients' experienced quality of life and psychological well-being and the resulting societal burden are increasingly recognized. However, there is limited knowledge on the economic burden of AIS. This cross-sectional, prevalence-based, bottom-up approach burden of disease study aims to determine the impact associated with adolescent idiopathic scoliosis in terms of the cost-of-illness and health-related quality of life from a societal perspective in the Netherlands.

Methods

Persons diagnosed with AIS or parents of a child with AIS that are willing and able to answer the questionnaires will be eligible to participate. Patients will be included consecutively between June until January 2023. Costs and self-perceived health-related quality of life will be estimated using 3 steps: identification, measurement and valuation. To assess the costs associated with AIS the institute for Medical Technology Assessment - Medical Consumption Questionnaire and the institute for Medical Technology Assessment - Productivity Cost Questionnaire will be used. To assess the HRQoL of adult AIS patients the EuroQol 5-dimensions or EuroQol 5-dimensions Youth questionnaire for children under the age of 12 and the Scoliosis Research Society-22 revised questionnaire will be considered.

Discussion

This is the first study in this field. It will help raise awareness for AIS and wider support for both the patient community and informal care takers among healthcare professionals and policymakers. Major strengths of this study will be the use of mostly validated, standardized questionnaires. Limitations include the cross-sectional and retrospective nature of the study design.

Patients' Perception and Satisfaction on Neck and Shoulder Imbalance in Adolescent Idiopathic Scoliosis

STUDY DESIGN

Cross-sectional.

OBJECTIVES

To evaluate the perception and satisfaction among adolescent idiopathic scoliosis (AIS) patients on Neck Tilt with Medial Shoulder Imbalance and Lateral Shoulder Imbalance.

METHODS

Lenke 1 and 2 AIS patients were stratified into 6 groups of preoperative/ postoperative Balanced (B), Lateral Shoulder Imbalance (LSI) (>2 cm), and Neck Tilt with Medial Shoulder Imbalance (NT) (Grade 3). Patients were interviewed using Modified Neck and Shoulder Appearance and SRS-22r questionnaires. T1 tilt, Cervical Axis (CA), Clavicle Angle (Cla-A) and Radiographic Shoulder Height (RSH) were measured.

RESULTS

A total of 120 Lenke 1 and 2 AIS patients were recruited. NT patients were aware and unhappy with their abnormal neck with medial shoulder appearances (P < .001). Similarly, LSI patients were aware and unhappy with their abnormal lateral shoulder appearances (P < .001). NT group had larger preoperative/ postoperative T1 tilt (9.2 ± 5.0°; 9.5 ± 5.3°) and CA (4.6 ± 3.1°; 7.0 ± 2.0°) (P < .01). LSI group had larger preoperative/ postoperative Cla-A (4.8 ± 2.8°; 4.0 ± 1.3°) and RSH (20.1 ± 9.4 mm; 17.0 ± 6.6 mm) (P < .001). Postoperative B group scored higher in overall SRS-22r scores, self-image and satisfaction domains (4.2 ± 0.3; 4.0 ± 0.5; 4.4 ± 0.5) while preoperative LSI scored the lowest comparatively (3.5 ± 0.4; 2.4 ± 0.5; 3.3 ± 0.5) (P < .001).

CONCLUSION

NT and LSI were major concerns among AIS patients. Both NT and LSI groups were unhappy with their appearances. NT group had larger T1 tilt/ CA whereas LSI group had larger Cla-A/ RSH. Postoperative B group scored higher in overall SRS-22r scores, self-image and satisfaction domains.

Why Don't Adolescents Wear Their Brace? A Prospective Study Investigating Psychosocial Characteristics That Predict Scoliosis Brace Wear

BACKGROUND

Although bracing for adolescent idiopathic scoliosis can prevent curve progression and reduce the risk for future surgery, children frequently do not wear their braces as prescribed. The purpose of this study is to investigate how a broad array of psychosocial characteristics predict future compliance with scoliosis brace wear.

METHODS

This was a single institution, prospective cohort study. All adolescents prescribed a first-time brace for adolescent idiopathic scoliosis were eligible. Patients and their parents completed a separate series of questionnaires that assessed baseline psychosocial characteristics across 6 domains: (1) brace-specific attitudes; (2) body image and self-esteem; (3) school performance and social relationships; (4) psychological health; (5) family functioning; and (6) demographics and scoliosis-specific details (242 total questions across 12 validated questionnaires). Objective brace compliance was collected using temperature-sensitive monitors. Defining compliance as percentage of brace prescription completed, comparative analyses were performed to identify baseline psychosocial characteristics that were associated with future wear. A composite measure (Bracing Fidelity Follow-Up Scale [BFFS]) of the 12 most predictive individual questions across all domains (both parent and adolescent) was constructed to help assess which adolescents were at highest risk of failure to wear their brace. Total BFFS score for each parent-adolescent dyad who completed all the included surveys was then determined by awarding one point for each factor that positively influenced future brace wear (maximum 12 points), and a correlation was calculated between total score and percent adherence to prescribed brace wear.

RESULTS

A total of 41 patients were included. On average, patients with high self-esteem, above average peer relationships and poor brace-specific attitudes had lower brace compliance, although patients with increased loneliness and parental religiousness had higher compliance. Body image, socioeconomic status, family dynamics, and school performance had no significant relationship with brace use. Total score on the Bracing Fidelity Follow-Up Scale (BFFS) was significantly associated with improved brace wear (r=0.687, P <0.001). Those with a score of 6 or above (n=15/33 [45%], median compliance 96%) were more reliable users (15/15 with compliance >75%), and those with a score of 5 or less (n=18/33 [55%], median compliance 50%) had less consistent brace wear (9/18 with compliance <50%).

CONCLUSION

This prospective study identifies numerous baseline psychosocial factors that are associated with future compliance with scoliosis brace wear. Although in need of further validation before widespread clinical application, the novel BFF scale offers a potential opportunity to partially discriminate between compliant and noncompliant scoliosis brace users such that supportive resources (eg, supportive counseling, peer-support groups, additional provider-based education, etc.) can be targeted to those patients most likely to benefit.

Disordered Eating and Body Image Concerns in Young Adult Women With Scoliosis

Background

Researchers have called for more investigation into disordered eating behaviors in females with scoliosis.

Objective

The objective of the current study was to assess the associations between body image concerns, disease-specific indicators of scoliosis (ie, age of diagnosis, having undergone bracing treatment, being told by a physician your scoliosis required surgery, having a spinal fusion), quality of life, and disordered eating in a sample of young adult women diagnosed with idiopathic scoliosis during adolescence.

Design

This study was cross-sectional in design.

Methods

Participants were 177 young adult women ages 18 to 30 years diagnosed with idiopathic scoliosis by a physician who completed questionnaires online.

Results

Undergoing bracing treatment (r = -.440; P < .001), greater age at scoliosis diagnosis (r = .563; P < .001), being told scoliosis required surgery (r = -.196; P < .050), annual income (r = .306; P < .001), level of education (r = .228; P < .010), and race/ethnicity (r = -.213; P < .050) were associated with the EDE-Q Global Score. The Body Shape Questionnaire Total Score and EDE-Q Global Score (r = .848; P < .001) and EDE-Q Weight Concern Score (r = .813; P < .001) were associated. The strongest correlations between the EDE-Q and the SRS-22-Revised Subscales were generally evidenced on the SRS-22-Revised Mental Health Subscale (rs ranged from -.200 to -.371; P < .001). After controlling for annual income, highest level of education, undergoing bracing treatment, and age of scoliosis diagnosis, the Body Shape Questionnaire Total Score was significantly correlated with the EDE-Q Eating Concern Score (standardized beta coefficient = .618; P < .001).

Conclusions

These findings underscore the importance of assessing body image concerns in young adult women with scoliosis experiencing disordered eating as this information may provide valuable information relevant to treatment planning.

Content validity of the Scoliosis Research Society questionnaire (SRS-22r): A qualitative concept elicitation study

INTRODUCTION

Scoliosis Research Society-22 revised (SRS-22r) is the common questionnaire used to evaluate health related quality of life (HRQOL) for young people with adolescent idiopathic scoliosis (AIS). The aim of this study is to evaluate its content validity for this population.

METHODS

In-depth semi-structured interviews were conducted with a purposive sample of young people with AIS (Cobb angle ≥25˚, aged 10-18 years). Concept elicitation was used to evaluate the influence of AIS on participants' HRQOL. Participant information sheets and consent/assent forms were age relevant. Topic guide was informed by the SRS-22r and existing evidence. Interviews were audio and video recorded, transcribed verbatim, coded, and analysed using thematic analysis. Derived themes/codes were compared with SRS-22r contents (domains/items).

RESULTS

Eleven participants (mean age 14.9 years [SD = 1.8]; 8 female) were recruited. The mean curve size was 47.5° [SD = 18°] and participants had been managed via different approaches. Four main themes emerged with associated subthemes: 1) Physical effects related to physical symptoms (back hurt, stiffness) and body asymmetry (uneven shoulders), 2) Activity-related effects showed impact on mobility (sitting for long periods), self-care (dressing), and school activities (focus during lessons), 3) Psychological effects revealed emotional (feel worried), mental (sleep quality), and body image effects (hide back from others), 4) Social effects (participation in school and leisure activities), and school, friends and mental health support. A weak association was found between items of the SRS-22r and the identified codes.

CONCLUSION

The SRS-22r does not adequately capture important concepts that relate to HRQOL of adolescents with AIS. These findings support revision of the SRS-22r, or the development of a new patient reported outcome measure to evaluate HRQOL of adolescents with AIS.

Correlational analysis of three-dimensional spinopelvic parameters with standing balance and gait characteristics in adolescent idiopathic scoliosis: A preliminary research on Lenke V

Background: Adolescent idiopathic scoliosis (AIS), the most common spinal deformity, possibly develops due to imbalanced spinal loading following asymmetric development. Since altered loading patterns may affect standing balance and gait, we investigated whether a correlation exists between balance ability, gait pattern, and the three-dimensional radiographic spinopelvic parameters in AIS patients. Methods: A cross-sectional observational study was conducted with 34 AIS patients (aged 10-18 years) and an equal number of healthy age and sex-matched teenagers (normal group). We obtained the spinopelvic three-dimensional parameters and balance parameters simultaneously through the EOS imaging system and gait and center of pressure (CoP) characteristics using a plantar pressure measurement mat. Besides determining the intergroup differences in balance and gait parameters, multiple linear regression analyses were performed to identify any correlation between the static plantar pressure and radiographic parameters. Results: Compared to the normal group, the CoPx is lower, the CoP path length and 90% confidence ellipse area were significantly higher in AIS patients (AIS: -13.7 ± 5.7 mm, 147.4 ± 58.1 mm, 150.5 ± 62.8 mm2; normal: -7.0 ± 5.4 mm, 78.8 ± 32.0 mm, 92.1 ± 41.7 mm2, respectively), correlated with apical vertebra translation, sagittal pelvic tilt, and pelvis axial rotation, respectively. Moreover, AIS patients had a shorter stance phase (61.35 ± 0.97 s vs. 62.39 ± 1.09 s), a longer swing phase (38.66 ± 0.97 s vs. 37.62 ± 1.08 s), and smaller maximum pressure peaks in the gait cycle, especially on the left foot, as compared to healthy subjects. Moreover, the CoP trajectory in AIS patients was different from the latter, and changes in the bipedal trend were not consistent. Conclusion: The standing balance and gait characteristics of AIS patients are different from those of healthy subjects, as reflected in their three-dimensional spinopelvic radiographic parameters. Trial registration: The study protocol was registered with the Chinese Clinical Trial Registry (Number ChCTR1800018310) and the Human Subject Committee of Guangzhou Sport University (Number: 2018LCLL003).

The Relationship Between Body Mass Index and the Magnitude of Curve at Diagnosis of Adolescent Idiopathic Scoliosis: A Retrospective Chart Review

Purpose

To evaluate the relationship between body mass index (BMI) and spinal curvature in patients presenting with idiopathic scoliosis at a major pediatric tertiary care centre.

Patients and Methods

Retrospective chart review (2015–2019). Data extracted from patient’s first visit included age, sex, height, weight, spinal curvature (magnitude, location), referral source, physical activity participation (yes/no), pain (yes/no). Demographics were analyzed descriptively. The relationship between BMI and spinal curve magnitude was analyzed using Spearman correlation coefficient. Linear regression was applied to determine the relationship between BMI, curve magnitude, and curve location. Exploratory univariate analyses were conducted for BMI and referral source, pain, and skeletal maturity, and physical activity and pain.

Results

A total of 206 patient charts were included (177 females, 29 males). Patients presented with double major (41.3%), thoracic (26.7%), thoracolumbar (22.8%), and lumbar (9.2%) curves. Mean (SD) BMI percentile was 48.3 (30.5). No relationship existed between BMI percentile and curve magnitude with curve locations combined. However, a test for interaction revealed a positive relationship between BMI percentile and curve magnitude for adolescents with double major curves, and a negative relationship for adolescents with thoracic curves. Exploratory analyses suggested a relationship between BMI percentile and presence of pain, and between referral source and curve magnitude. No relationship was observed between BMI and skeletal maturity, or physical activity and pain.

Conclusion

The relationship between BMI varied by curve location within this cohort, in which most patients presented with a BMI <85th percentile. Findings highlight the importance of sensitive history taking and careful physical examination for early detection of scoliosis.

Evaluation of Self-Perceived Body Image in Adolescents with Mild Idiopathic Scoliosis

Adolescent idiopathic scoliosis (AIS) is the most prevalent types of scoliosis, affecting up to 3% of children around the world. The progression of AIS can cause alteration in psychological components such as self-perceived body image and self-identity, which negatively affect the teenager quality of life (QoL). The mainly aim of this cross-sectional study is to investigate how mild AIS impacts self-perceived body image in young people. Fifteen participants (mean age = 14.47 ± 2.825) of both sexes (male = 5; female = 10) with a curve magnitude from 10° up to 25° completed the Scoliosis Research Society Patient Questionnaire (SRS-22), the Trunk Appearance Perception Scale (TAPS) and were subject to spinal analysis and photogrammetry. Results display statistical differences between self-perceived body image and other SRS-22 domains (Hotelling t2= 70.29; F(3,12) = 20.08; p < 0.001). Additionally, the regression model, which better explained the self-perceived variability, was fit by function/activity, pain, and mental health domains (F(4,10) = 4.39; p = 0.029; R2 = 0.545). Although AIS was not severe, it negatively affected participants self-perceived body image. More attention in AIS qualify of life is needed, and early treatments could be necessary to prevent psychological impairments self-perception related.

Three-dimensional corrective exercise therapy for idiopathic scoliosis: study protocol for a prospective non-randomized trial

Background

Although physiotherapeutic scoliosis-specific exercises (PSSEs) with or without other conservative treatments may improve scoliotic deformities, the evidence is insufficient. Three-dimensional corrective exercises (TDCEs) for scoliosis are based on the theory of PSSEs and are characterized by a combination of outpatient treatment and home-based exercise. This study aims to evaluate the effectiveness of TDCEs for idiopathic scoliosis (IS).

Methods

The participants will be divided into two age- and sex-matched groups: an experimental group (EG) treated with three-dimensional corrective exercise therapy (TDCET) and a control group (CG) receiving generalized exercise therapy. In each arm, mild and moderate IS cases will be reclassified based on the Cobb angle and biopsy results. The primary endpoint is the change in the largest Cobb angle; the secondary endpoints are the sagittal index, forced vital capacity, peak oxygen uptake, and peak oxygen uptake. Sixty-six patients with mild IS and 78 patients with moderate IS will be included.

Discussion

This study is the first controlled trial to systematically assess the effectiveness of TDCEs for IS. In addition to TDCET including three-dimensional corrective exercises, family rehabilitation and basic body awareness therapy may help patients adopt supportive attitudes and appropriate behaviours, thus enhancing their compliance with exercises and achieving better outcomes.

Trial registration

The study protocol was registered at www.clinicaltrials.gov (number identifier: NCT04539522). Registered on August 27, 2020.

Is self-image, in reference to the gravitational vertical, altered in adolescent idiopathic scoliosis? A multicenter, single-blind, case-control study

PURPOSE

Adolescent idiopathic scoliosis (AIS) is associated with perturbation of orthostatic postural control. In humans, orthostatic postural control is organized around the gravitational vertical (GV). Perception of the GV involves a bottom-up process (central integration of multisensorial information) and a top-down process that uses cognitive mechanisms relying on body image. This study hypothesized that AIS would be associated with an erroneous central representation of verticality. The objective was to demonstrate an altered top-down process of sense of verticality in AIS.

METHODS

This multicenter, single-blind, case-control study evaluated 63 adolescent girls with AIS divided into two groups (major AIS (n = 31) and minor AIS (n = 32)) and 30 matched non-scoliotic adolescents. Participants scored their perception of trunk appearance in an upright position using a pictographic scale. The outcome measure was the difference between perception score and real trunk deformity.

RESULTS

Participants with major AIS presented with misperception of their trunk appearance in an upright position when compared with those with minor AIS or controls.

CONCLUSION

Adolescents with major AIS underestimate their trunk deformity in an upright position. This suggests an altered representation of body image, affecting top-down control of sense of verticality.

Adolescents' Experiences of Idiopathic Scoliosis in the Presurgical Period: A Qualitative Study

OBJECTIVE

Adolescent idiopathic scoliosis (AIS) is a sideways curvature of the spine that can progress severely during adolescent development and require surgical intervention. This qualitative study was conducted to explore the psychosocial experiences of adolescents with idiopathic scoliosis during the presurgical stage of treatment.

METHODS

Fourteen adolescents with moderate-to-severe AIS aged 12-17 years participated in semistructured interviews and data were analyzed using inductive reflexive thematic analysis.

RESULTS

Four key themes were generated from the analysis. "Proceeding with Caution" described adolescents' adaptation to the physical impact of their AIS, while "Am I Different?" encompassed adolescents' perceptions of their changing appearance and visibility of their condition. "An Emotional Journey" captured the rollercoaster of emotions from shock at diagnosis to the daunting realization of the severity of their condition, while knowing others with AIS could ease the emotional burden. Finally, adolescents' concerns and expectations about their prospective surgery were captured by the theme "No Pain, No Gain", whereby they were often keen to put surgery behind them.

CONCLUSIONS

Understanding and addressing adolescents' psychosocial support needs as they manage the challenges associated with idiopathic scoliosis is a key component of promoting better outcomes among this patient group. Clinical implications and opportunities for support provision are discussed.

Development and validation of the scoliosis misconception scale (SMS) for assessing level of misconception of patients with adolescent idiopathic scoliosis

BACKGROUND

Little is known about patients' understanding of adolescent idiopathic scoliosis (AIS). This paper aims to develop and validate the Scoliosis Misconception Scale (SMS) and to explore patients' level of misconception about AIS.

METHODS

A total of 195 patients who were newly referred with newly diagnosed AIS were recruited to assess their levels of misconception and psychological distress before and after their first consultation with a specialist. The 17-item SMS was administered to assess patients' level of misconception about AIS and the Kessler Psychological Distress Scale (K10) was used to measure their level of distress.

RESULTS

According to the Item Response Theory, all items were within the acceptable range from -3.69 to 2.39 for difficulty parameters, which determined the difficulty of the scale, while most of the items were within the acceptable range from 0.11 to 1.54 for the discrimination parameters, which determined the rate at which the probability of endorsing a correct item changes given ability levels. Internal consistency by marginal reliability was 0.66. One-sample t test revealed that participants on average scored 6.79 (SD = 2.12) before the first clinic session and 6.45 (SD = 2.51) after the first clinic session, both significantly higher than 0 [t(75) = 27.86, p < .001; t(75) = 22.43, p < .001].

CONCLUSIONS

Despite a longstanding clinical model that functions well to treat AIS, most patients still have significant misconceptions about the condition. This highlights the necessity to assess patients' knowledge level of a medical condition and potential generalisability of misconception-distress link to the forefront across other illnesses.

Is There an Association Between Psychiatric Disorders and Adolescent Idiopathic Scoliosis? A Large-database Study

BACKGROUND

Children with adolescent idiopathic scoliosis (AIS) have reduced quality of life related to poor self-image, perhaps because of cosmetic concerns. However, there has not been a large-database epidemiologic study on the association between psychiatric disorders and scoliosis.

QUESTIONS/PURPOSES

Using the Korean National Health Insurance database, we asked: (1) How common are psychiatric disorders among children with AIS? (2) After controlling for gender, age, insurance type, and residential district, are psychiatric disorders more common among children with AIS than among age-matched controls?

METHODS

A retrospective analysis was conducted using sample datasets from the Health Insurance Review and Assessment Service from 2012 to 2016, which is a 10% randomly extracted sample of total inpatients and outpatients each year. The mean number of total patients in each dataset was 1,047,603 ± 34,534. The mean number of children with AIS was 7409 ± 158 for each year. The age criteria was 10 to 19 years for the matching. Mood disorders, anxiety disorders, and behavioral disorders were selected as disorders possibly associated with AIS. We identified children with AIS who had any of the disorders above, and we obtained the prevalence of these disorders based on diagnostic codes. As an exploratory analysis, clinically meaningful variables were selected among the available codes in the dataset, and a univariable logistic regression test was performed for each variable. A multivariable logistic regression test with advanced variables was performed to identify the adjusted odds ratios of psychiatric disorders in children with AIS.

RESULTS

The median (range) prevalence of psychiatric disorders in children with AIS from 2012 to 2016 was 7% (6% to 7%). Compared with children who did not have AIS, and after controlling for gender, age, insurance type, and residential district, children with AIS were more likely to have psychiatric disorders in all 5 years. The adjusted ORs of psychiatric disorders in children with AIS compared with children who did not have AIS ranged from 1.47 to 1.74 (2012: OR 1.60 [95% CI 1.46 to 1.75]; p < 0.001; 2013: OR 1.73 [95% CI 1.58 to 1.89]; p < 0.001; 2014: OR 1.74 [95% CI 1.59 to 1.91]; p < 0.001; 2015: OR 1.71 [95% CI 1.56 to 1.88]; p < 0.001; 2016: OR 1.47 [95% CI 1.33 to 1.62]; p < 0.001).

CONCLUSION

Considering the higher prevalence of psychiatric disorders in children with AIS compared with children who did not have AIS, children with AIS and their parents should be counseled about the increased risk of deteriorating mental health of the patients, and surgeons should provide early referral to pediatric psychiatrists. Further studies should investigate the effect of the factors related to AIS, such as curve type, Cobb angle, and treatment modality.

What does the SRS-22 outcome measure tell us about spinal deformity surgery for Adolescent Idiopathic Scoliosis in the UK?

INTRODUCTION

The purpose of this study was to analyse SRS-22 outcomes measures recorded on the British Spine Registry (BSR) for adolescent idiopathic scoliosis (AIS) surgery in the UK.

METHODS

All cases having completed an SRS-22 outcome score and labelled with a diagnosis code of 'AIS' on the BSR were analysed. The SRS-22 score for primary cases was analysed by both individual domains and as a total score over time following surgery.

RESULTS

A total of 3,860 cases were labelled as AIS recorded from 3,481 individuals. For primary cases, surgery improved the SRS-22 scores in every domain and as a total score, and this was maintained over time. There was no significant change in the scores recorded between 1 and 2 years of follow up apart from in function (and thus total score) for primary cases.

CONCLUSIONS

Surgery for AIS in the UK improves quality of life assessed using SRS-22. Mandatory follow up to 2 years postoperatively adds little information not already known at 1 year. We recommend that the Best Practice Tariff incorporates the collection of outcomes data as this is likely to reduce missing data.

Parents' information needs, treatment concerns, and psychological well-being when their child is diagnosed with adolescent idiopathic scoliosis: A systematic review

OBJECTIVE

We systematically reviewed the experiences of parents who have a child with adolescent idiopathic scoliosis in order to understand their needs and concerns related to their child's healthcare, and assist health professionals in supporting parents of this paediatric patient group.

METHODS

A systematic search strategy identified eighteen relevant studies published between 2000 and 2020. Quality was assessed using the Mixed Methods Appraisal Tool and the literature was narratively synthesised.

RESULTS

Three main themes were evident across the literature including information needs, treatment concerns, and psychological well-being. Studies predominantly focused on the surgical treatment of scoliosis.

CONCLUSION

Parents face challenges such as acquiring appropriate knowledge about scoliosis to participate in healthcare decisions and coping with their child undergoing invasive spinal surgery. Throughout this time, their psychological well-being can be negatively impacted. Considering parents' experiences and support needs throughout this anxiety-provoking time is an important step in delivering family-centered care and promoting better outcomes for paediatric patients.

PRACTICE IMPLICATIONS

Providing parents with appropriate resources and addressing concerns around surgical complications, postoperative pain, and how they can best support their child before and after surgery, may alleviate some of the emotional burden that parents experience.

LONG-TERM FOLLOW-UP OF AIS TREATED SURGICALLY WITH PEDICULAR SCREWS

ABSTRACT Objective: In the last three decades, there have been great advances in the surgical treatment of adolescent idiopathic scoliosis. There are few studies that focus on the long-term clinical and radiographic results of AIS operated on with pedicle screws that also consider psychological repercussions. Methods: We conducted an observational longitudinal study. We reviewed the AIS cases that were operated on with pedicle screws in our center between January 2009 and December 2010. We conducted follow-up until July 2019. A short questionnaire was administered to assess patient satisfaction and the long-term impact from both psychological and functional points of view. Results: A total of 19 patients met the inclusion criteria. The mean preoperative Cobb was 58°, the postoperative was 23° and at the end of follow-up it was 26°. No major complications were reported. Ninety percent were very satisfied with the overall results of the surgery. Ninety-five percent had no limitation for sports or daily activities and 90% were satisfied with the cosmetic results. Conclusion: The short- and long-term radiographic evolution in patients treated with third generation material presented good clinical results. In 3 cases (16%) loss of correction greater than 10% was reported. The overall satisfaction index and cosmetic results were very good at the end of follow-up despite the low correction rate (60%). There were no major complications and the incidence of functional limitation and pain at the end of the follow-up was very low. Level of evidence IV; Review article.

An Analysis of Eating Disorders in Adolescent Idiopathic Scoliosis: A Prospective Cross-sectional Study in a Female Population

STUDY DESIGN

Prospective cross-sectional study.

OBJECTIVE

We designed this study to investigate whether adolescent girls with idiopathic scoliosis show a predisposition for eating disorders (EDs) and alterations of the quality of life and body image self-perception, compared to same-age healthy females.

SUMMARY OF BACKGROUND DATA

Idiopathic scoliosis is the most common spinal deformity of adolescence. Recent findings about the impairment of the self-body image in adolescents with idiopathic scoliosis provide a common trait of scoliosis and EDs and could lead to the suspicion of an association between these two pathological conditions. Despite this, current literature shows the lack of evident results about the impact of adolescent idiopathic scoliosis (AIS) on the possibility to develop of EDs.

METHODS

One hundred forty-four females with diagnosis of AIS (aged 10-18 years) formed the scoliosis group. One hundred forty-six same-age healthy girls were enrolled in the control group. For all subjects, we considered sport practice. Only for Scoliosis Group, we also considered the severity of scoliosis, the use of brace and the practice of physiotherapy scoliosis-specific exercises. The participants were asked to answer to the Scoliosis Research Society-22 revised Patient Questionnaire (SRS-22r) and the Eating Disorders Inventory (EDI).

RESULTS

In the scoliosis group, significantly lower scores on the SRS-22r total and in the self-image domain were detected. The two groups showed differences in the total EDI score and in the body dissatisfaction EDI's domain. Severity of scoliosis was correlated with worse SRS-22r total score and SRS-22r self-image domain score. There were no differences in the scores of the SRS-22r and EDI between braced and nonbraced subjects. Lower scores in SRS-22r total and self-image domain were found in girls who practiced physiotherapy exercises. Subjects who practiced a sport showed higher SRS-22r total scores.

CONCLUSION

The AIS cohort in our study demonstrated lower levels of eating psychopathology than healthy controls. Surprisingly, eating behavior does not seem to be affected by orthotic management. However, quality of life and self-body image could be impaired in scoliotic girls, especially when they practice physiotherapy exercises, whereas those who practice sport seem to be preserved in this regard.Level of Evidence: 4.

Isometric Yoga-Like Maneuvers Improve Adolescent Idiopathic Scoliosis-A Nonrandomized Control Trial

Objective

Assess therapeutic value of specific yoga poses for thoracic and lumbar adolescent idiopathic scoliosis (AIS) taught in office or Internet.

Study Design

Nonrandomized control trial: Fifty-six adolescents (mean age 14.0 years; mean Risser 3.0) were recruited from our clinic; 41 did the side-plank, the half-moon and elevated side plank poses as appropriate (treatment group) and 15 did not (controls). Thirty curves were treated in office, 30 via Internet. Curve change was evaluated by blinded serial Cobb angles, and analyzed using Mann-Whitney U, paired t-tests and χ².

Results

Mean lumbar and thoracolumbar Cobb angle change was −9.2 (95% CI = −11.8, −6.6) in the treatment group and 5.4 (95% CI = 1.7, 9.0) in controls. Both treatment group improvement and deterioration in controls were significant (treatment group: paired t-test t = −7.1, df = 40, p = .000; controls: t = 3.2, df = 12, p = .008). Mean thoracic Cobb angle change was −7.1 (95% CI = −13.1, −1.2) in the treatment group and 9.3 (95% CI = 4.5, 14.6) in controls. Both changes were significant (paired t-test t = −3.3, df = 21, p = .022 for treatment group; t = 4.5, df = 5, p = .006 for controls). Nine Internet patients were non-compliant vs. 6 office patients. Office patients improved 1.6 degrees/month or 5.5%/month; Internet patients improved .72 degrees/month or 3.3%/month.

Conclusion

These yoga poses show promise for reversing adolescent idiopathic scoliosis. Telemedicine had greater non-compliance and lower efficacy but still produced patient improvement.

Discrimination Ability of Patient Reported Outcome Measurement Information System Pediatric Domains Compared With Scoliosis Research Society-22r and Legacy Patient Reported Outcome Measures in Juvenile and Adolescent Idiopathic Scoliosis

STUDY DESIGN

Comparative cohort study.

OBJECTIVE

To compare patient reported outcome measures (PROMs) in children and adolescents with varying extent of spinal deformity.

SUMMARY OF BACKGROUND DATA

Several PROMs have been proposed to help assess health-related quality-of-life (HRQoL) in pediatric spinal deformity surgery and research, but it is unclear which are sensitive to deformity severity.

METHODS

Pediatric patients diagnosed with spinal asymmetry or juvenile/adolescent idiopathic scoliosis completed the patient-reported outcomes management information system (PROMIS) pediatric computer adaptive test bank (Domains: Mobility, Pain Interference, Physical Activity, Physical Stress Experiences, Psychological Stress Experiences), Scoliosis Research Society-22r (SRS-22r), Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS) activity scale, and Trunk Appearance Perception Scale. Patients were grouped as spinal asymmetry, mild deformity, and substantial deformity by major Cobb angle measuring less than 10°, between 10° and 40°, and greater than 40° respectively. One-way analysis of variance with a Tukey post-hoc correction was used to determine score differences between groups.

RESULTS

Final analyses included 206 patients, of which 135 (66%) were female. The mean age was 13.0 ± 2.2 years, and the mean major Cobb angle was 20.1 ± 14.1° (range: 0-74.2°). Compared with both spinal asymmetry and mild deformity patients, patients with substantial deformity reported worse outcomes, including lower function, more pain, and decreased psychological health by legacy PROMs and PROMIS. PROMIS Physical Activity and Psychological Stress Experiences did not capture any significant differences between all groups. There were no significant differences in outcomes between the spinal asymmetry and mild deformity groups for all PROMs measured.

CONCLUSION

Patients with substantial spinal deformity reported lower activity and function, more pain, and greater physical and psychological stress compared with patients without clinical spinal deformity by legacy PROMs and several PROMIS domains. As PROMIS Physical Activity and Psychological Stress Experiences did not capture these differences, these PROMs may measure different constructs than the legacy PROMs as they relate to spinal curvature and may be less relevant to measure HRQoL in this population.Level of Evidence 3.

Disordered leptin and ghrelin bioactivity in adolescent idiopathic scoliosis (AIS): a systematic review and meta-analysis

Background

Adolescents with scoliosis consistently demonstrate lower body weight, lean muscle mass, and bone mineral density than healthy adolescent counterparts. Recent studies have focused on understanding how leptin and ghrelin signaling may play a role in adolescent idiopathic scoliosis (AIS). In our current study, we aim to evaluate the serum levels of leptin, soluble leptin receptor (sOB-R), and ghrelin in AIS patients through systematic review and meta-analysis.

Methods

We conducted our systematic review by searching the keywords in online databases including PubMed, Embase, Cochrane, Elsevier, Springer, and Web of Science from the time of database inception to January 2020. Inclusion criteria were studies that measure leptin, soluble leptin receptor (sOB-R), and ghrelin levels in AIS patients. Selection of studies, assessment of study quality, and data extraction were performed by two reviewers independently. Then, data was analyzed to calculate the mean difference and 95% confidence interval (CI).

Results

Seven studies concerning leptin/sOB-R and three studies concerning ghrelin were qualified for meta-analysis (one study concerning both leptin and ghrelin). Serum leptin of patients with AIS were significantly lower when compared with healthy controls, with the weighted mean difference (WMD) of − 0.95 (95% CI − 1.43 to − 0.48, p < 0.0001) after reducing the heterogeneity using six studies for meta-analysis, while sOB-R and ghrelin level was significantly higher in AIS group when compared with control group, with the WMD of 2.64 (95% CI 1.60 to 3.67, p < 0.001) and 1.42 (95% CI 0.48 to 2.35, p = 0.003), respectively.

Conclusion

Our current meta-analysis showed that serum level of leptin in AIS patients was significantly lower when compared with control subjects, while serum sOB-R and ghrelin levels were significantly higher in AIS patients. More clinical studies are still required to further validate the predictive value of leptin or ghrelin for the curve progression for AIS patients.

A report of the number of adolescents screened as warranting further investigation for depression and social anxiety in a pre-operative cohort with idiopathic scoliosis

INTRODUCTION

Adolescent Idiopathic Scoliosis (AIS) is a common form of scoliosis, causing rotational deformity of the torso in a teenage population. In AIS this happens at a time of particular psychological development and vulnerability and a link between AIS and mental health problems has been observed.

MATERIALS AND METHODS

Over a 6 month period, all patients with AIS aged 10-18 referred to a single spinal deformity centre in the UK were screened for symptoms suggestive of a potential diagnosis of depression and social anxiety.

RESULTS

Of the 33 patients surveyed, 6 (18%) had scores worthy of further assessment for a potential diagnosis of depression and 19 (59%) worthy of further assessment for a potential diagnosis of social anxiety.

DISCUSSION AND CONCLUSION

This small study supports the notion that there is an association between AIS and mental health issues. These initial findings support the practice of routine mental health screening in AIS.

The Effect of Bracing on Spinopelvic Rotation and Psychosocial Parameters in Adolescents with Idiopathic Scoliosis

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.
