Physiotherapy scoliosis-specific exercises - a comprehensive review of seven major schools

The efficacy of combined physiotherapeutic scoliosis-specific exercises and manual therapy in adolescent idiopathic scoliosis

BACKGROUND

Adolescent idiopathic scoliosis (AIS) is a pathological condition characterized by vertebral curvature and associated trunk deformities in adolescents. The clinical efficacy of conservative treatment in alleviating spinal curvature of AIS remains a topic of ongoing debate. The objective of this study was to investigate the impact of combined physiotherapeutic scoliosis-specific exercises (PSSE) and manual therapy (MT) on trunk deformity, spinal function, mobility, and mental health in patients with AIS.

METHODS

Thirty-one participants who were diagnosed with AIS whose Cobb angle was between 10-45°were enrolled in the study. Participants in the intervention group received 50 min of PSSE combined with 10 min of MT, while the control group performed 50 min of PSSE as their home exercise program. Both treatments were implemented three times a week for four weeks. Cobb angle, spinal mobility, trunk morphology (vertebral rotation angle, apical deviation, pelvic obliquity distance and angle), movement capability, and quality of life (QOL) were assessed at baseline and post intervention. The treatment effects between the intervention and control groups were analyzed using a two-way repeated measures ANOVA.

RESULTS

Following a 4-week treatment period, Cobb angle was significantly reduced from 21.58° to 18.58° in intervention group and increased from 18.00° at baseline and 19.14° post intervention in the control group. Significant improvements were also observed in spinal mobility, movement capability, quality of life, and some of the trunk morphology indices in the intervention group compared to baseline (p < 0.05). Improvements were significantly higher in the intervention group than the control group.

CONCLUSION

Combining PSSE and MT shows potential benefits in alleviating AIS symptoms and improving QOL. Further studies to substantiate these findings are warranted.

TRIAL REGISTRATION

The trial was retrospectively registered in the Chinese Clinical Trial Registry ( https://www.chictr.org.cn ) with the registration number: ChiCTR2300071357, (Date: 12/05/2023).

Towards Wearable and Portable Spine Motion Analysis Through Dynamic Optimization of Smartphone Videos and IMU Data

BACKGROUND

Monitoring spine kinematics is crucial for applications like disease evaluation and ergonomics analysis. However, the small scale of vertebrae and the number of degrees of freedom present significant challenges for noninvasive and convenient spine kinematics estimation.

METHODS

This study developed a dynamic optimization framework for wearable spine motion tracking at the intervertebral joint level by integrating smartphone videos and Inertia Measurement Units (IMUs) with dynamic constraints from a thoracolumbar spine model. Validation involved motion data from 10 healthy males performing static standing, dynamic upright trunk rotations, and gait. This data included rotations of ten IMUs on vertebrae and virtual landmarks from three smartphone videos preprocessed by OpenCap, an application leveraging computer vision for pose estimation. The kinematic measures derived from the optimized solution were compared against simultaneously collected infrared optical marker-based measurements and in vivo literature data. Solutions only based on IMUs or videos were also compared for accuracy evaluation.

RESULTS

The proposed optimization approach closely matched the reference data in the intervertebral or segmental rotation range, demonstrating minimal angular differences across all motions and the highest correlation in 3D rotations (maximal Pearson and intraclass correlation coefficients of 0.92 and 0.94, respectively). Time-series changes of joint angles also aligned well with the optical-marker reference.

CONCLUSION

Dynamic optimization of the spine simulation that integrates IMUs and computer vision outperforms the single-modality method.

SIGNIFICANCE

This markerless 3D spine motion capture method holds potential for spinal health assessment in large cohorts in real-world settings without dedicated laboratories.

Conservative Treatments of Adolescent Idiopathic Scoliosis: Physical Therapists' Perspectives

This study aimed to examine physical therapists' perspectives in conservative treatments of pediatric patients with adolescent idiopathic scoliosis (AIS). A cross-sectional survey design was used. A validated questionnaire was distributed to physical therapists, and the responses were analyzed. Preferred treatment frequency was 60 minutes (53.8%), twice weekly (41.5%), over 3 to 5 months (44.6%). Top 3 clinical interventions were core and trunk stability enhancement (90.8%), abdominal strengthening (83.1%), and postural correction (80.0%). Top 3 therapeutic goal-setting parameters were activity-based (78.5%), quality-of-life measure-based (56.9%), and participation-based (50.8%). The most common quality-of-life survey used was Oswestry low back pain disability questionnaire (15.6%) followed by Scoliosis Research Society-22 instrument (12.5%). According to our data, physical therapists believe that pediatric patients with AIS can benefit with addressing core and trunk stability, a 60-minute per session, twice weekly, over 3 to 5 months based on activity-based goal-setting and quality-of-life measures using Oswestry questionnaire.

The Schroth Method for Pediatric Scoliosis: A Systematic and Critical Analysis Review

BACKGROUND

The Schroth method is the most commonly used patient scoliosis-specific exercise paradigm for treating pediatric scoliosis. The aim of this study is to systematically and critically examine the evidence for the Schroth method for pediatric scoliosis.

METHODS

PubMed, MEDLINE, CINAHL, and Web of Science were searched through April 5, 2024, for articles examining the Schroth method for pediatric scoliosis (<18 years old). Thirteen review questions were created spanning the study aim. Each included article was independently assessed for the level of evidence (I-IV). Research questions were given a grade of recommendation (A, B, C, and I [insufficient]).

RESULTS

A total of 29 articles (41.4% Level I, 31.0% Level II, 13.8% Level II, and 13.8% Level IV) met inclusion criteria out of 845 initially retrieved, describing 1,555 patients with scoliosis aged 4 to 18 years. There was grade A evidence that the Schroth method is most commonly used for adolescent idiopathic scoliosis (AIS), can improve the angle of trunk rotation, and is safe; grade B evidence for improvement in posture; and grade I evidence for improvement in Cobb angle, cosmetic deformity, quality of life, ideal treatment parameters, economic value, utility in delaying/preventing surgery, effectiveness in relation to patient characteristics (e.g., skeletal maturity or curve size), and comparative effectiveness to other conservative interventions.

CONCLUSION

While there is good evidence that the Schroth method is commonly and safely used in AIS and can minimally improve the angle of trunk rotation and fair evidence of improvement in posture, there is insufficient evidence regarding multiple important clinical and economic outcomes, such as comparative effectiveness to other conservative interventions and improvement of Cobb angle. Although clinicians may consider the Schroth method as 1 option of several conservative strategies, clinical benefit may be limited, and further high-quality research is needed to evaluate its performance in areas of insufficient evidence.

Comparison of the efficacy of Schroth and Lyon exercise treatment techniques in adolescent idiopathic scoliosis: A randomized controlled, assessor and statistician blinded study

BACKGROUND

Adolescent idiopathic scoliosis (AIS) is the most common vertebral disorder in adolescence.

OBJECTIVES

The purpose of this study was to compare the effectiveness of Schroth and Lyon exercise methods on Cobb angle (CA), angle of trunk rotation (ATR), quality of life (QoL), and perceived trunk appearance in patients with AIS.

METHODS

The 31 participants diagnosed (diagnosis age = 12.2 ± 0.9) with AIS by a physician following the Lenke criteria and subsequently referred to the outpatient clinic were enrolled in the study. All participants were randomly assigned between the Schroth group (SG) and Lyon group (LG) for 6 months of supervised and home treatment. The participants' CA, ATR, Scoliosis Research Society-22 (SRS-22), and Walter-Reed Visual Assessment Scale (WRVAS) were assessed as a baseline, and again following the treatment by the same researcher who remained blinded to the study.

RESULTS

In 2-way mixed-design repeated-measures ANOVA analysis, when the change in time was analyzed between the groups (Group × Time [interaction]), a statistical difference was found more significant in SG for the CA-thoracic (F = 103.1, p < .01, 95% CI = 4.1; 2.0 to 6.2), CA-lumbar (F = 19.1, p < .01, 95% CI = 1.7; 1.0 to 2.4), ATR (F = 64.1, p < .01, 95% CI = 1.7; 1.2 to 2.3), and WRVAS (F = 169.5, p < .01, 95% CI = 6.5; 3.2 to 9.9) parameters. The LG was only more significantly improved in the SRS-22 total score (F = 15.7, p < .01, 95% CI = -0.9; -0.2 to -1.6).

CONCLUSION

In the study, The Schroth exercises gave more favorable results than Lyon exercises in terms of CA-T, CA-L, ATR and WRVAS in the conservative treatment of AIS, while Lyon exercises gave more favorable results in terms of QoL. Additionally, according to the results of this study, it was found that the QoL of participants in SG decreased after treatment compared to baseline.

Impact of Idiopathic Scoliosis on the Cardiopulmonary Capacity of Adolescents

Chest deformities in children with scoliosis may result in cardiopulmonary disorders, lowering cardiopulmonary capacity levels. However, results regarding the dependence of cardiopulmonary capacity on the severity level of scoliosis remain controversial. We aimed to use dynamic cardiopulmonary exercise testing (CPET) to investigate exercise capacity in reference to spinal deformity in patients with mild or moderate idiopathic scoliosis by means of multivariate analyses. Methods: We included 92 children and adolescents aged 10-17 years with mild and moderate idiopathic scoliosis and 94 healthy peers. The study consisted of three parts: (1) medical record analyses; (2) anthropometric measurements; and (3) CPET. Results: Our results revealed that the mean VO2peak and VO2peak/kg values of the participants with scoliosis were 0.27 L/min and 0.37 mL/min/kg lower than their healthy peers, respectively, regardless of age and gender. Furthermore, the occurrence of scoliosis correlates with a mean decrease in minute ventilation volume by 10.10 L/min, tidal volume by 0.11 L, breathing frequency by 3.78 bpm, and breathing reserve by 14.34%, regardless of the age and gender of the participants. Children and adolescents with mild-to-moderate scoliosis during CPET exhibit a lower ventilation capacity and lower VO2 max than healthy adolescents matched in age but their cardiorespiratory fitness parameters do not depend on the Cobb angle value and the angle rotation of the primary spinal curvature. Conclusions: Physical therapy and activity should be recommended to prevent cardiorespiratory failure in later life in patients with scoliosis. This study may also provide CPET reference values for healthy children and adolescents with scoliosis.

A Novel Classification of Juvenile and Adolescent Idiopathic Scoliosis for Conservative Treatment

BACKGROUND

The operative classification of scoliosis is well-developed but inadequate for guiding conservative treatment. The current conservative classification for juvenile and adolescent idiopathic scoliosis (JAIS) exhibits noticeable deficiencies. This study aimed to establish the Peking Union Medical College Hospital (PUMCH) classification and assess its clinical value in the conservative treatment of JAIS.

METHODS

This study consisted of 2 parts. First, it involved a retrospective analysis of patients treated for JAIS in the Department of Rehabilitation Medicine, the ∗∗∗ Union Medical College Hospital, between January 2013 and June 2020. Second, it involved an ambispective cohort study that enrolled patients with JAIS in the above hospital between July and December 2020.

RESULTS

A total of 989 patients with JAIS were enrolled, with 899 patients for establishing the PUMCH classification and 90 patients with JAIS for validating the PUMCH classification. The classification demonstrated an average reliability of 88.22% with a kappa coefficient of 0.862. After 1 week, the remeasured results presented a mean reproducibility of 92.78% and a kappa coefficient of 0.908. After 1-year follow-up, the Cobb angle decreased significantly from 16.61 ± 2.88° to 12.16°± 9.97° (P = 0.002) in 51 patients with PUMCH-scoliosis-specific exercise (SSE) treatment, while the Cobb angle increased significantly from 15.74 ± 2.75° to 17.64 ± 5.60° (P = 0.014) in 39 patients without PUMCH-SSE treatment.

CONCLUSIONS

The PUMCH-SSE classification demonstrates good inter-observer reliability and intra-observer reproducibility. In addition, the classification may be used to guide the conservative treatment of JAIS in clinical settings.

Adolescent idiopathic scoliosis in adulthood

Adolescent idiopathic scoliosis (AIS) is an abnormal coronal curvature of the spine that most commonly presents in adolescence. While it may be asymptomatic, AIS can cause pain, cosmetic deformity, and physical and psychological disability with curve progression. As adolescents with AIS enter adulthood, condition outcomes vary with some experiencing curve stabilization and others noting further curve progression, chronic pain, osteoporosis/fractures, declines in pulmonary and functional capacity, among others. Regular monitoring and individualized management by healthcare professionals are crucial to address the diverse challenges and provide appropriate support for a fulfilling adult life with AIS. This review examines the prevalence, risk factors, presenting symptoms, diagnosis, management, and complications of AIS in the adult population, informing targeted interventions by clinicians caring for adult patients with AIS.

Incidence and Importance of Peripheral Vestibular Dysfunction in Adolescent Idiopathic Scoliosis

Adolescent idiopathic scoliosis (AIS) is a common form of scoliosis. As the name suggests, etiopathogenesis is not clearly defined, so treatment is still anchored in the musculoskeletal theory and correction/prevention of high Cobb angle values. This study aimed to determine whether there is any connection between developing scoliotic curvature and a positive history of motion sickness as a symptom of a peripheral vestibular dysfunction/deficit, and if vestibular rehabilitation exercises could be integrated into the treatment plan. The study was conducted over 12 months on a selected population of 159 patients to evaluate or treat scoliotic curvatures in a private clinic. The collected data were analyzed using IBM SPSS Statistics 25 and illustrated using Microsoft Office Excel/Word 2021. Patients with peripheral vestibular dysfunction had significantly higher Cobb angle values when compared to patients with a negative result in an instrumental test for peripheral vestibular dysfunction. Motion sickness was considerably more associated with peripheral vestibular dysfunction, and a positive Fukuda stepping test was associated with a positive history of motion sickness. Adolescent idiopathic scoliosis with higher Cobb angles is related to positive motion sickness history as part of peripheral vestibular dysfunction. Conservative treatment for scoliosis could incorporate sensory integration techniques, and a positive history of motion sickness could be an indicator of a higher risk of progression in adolescent idiopathic scoliosis.

Development of a Motion-Based Video Game for Postural Training: A Feasibility Study on Older Adults With Adult Degenerative Scoliosis

Forward sagittal alignment affects physical performance, is associated with pain and impacts the health-related quality of life of the elderly. Interventions that help seniors to improve sagittal balance are needed to inhibit the progression of pain and disability. A motion-sensing video game (active game) is developed in this study to monitor sitting and standing postures in real-time and facilitate the postural learning process by using optical sensors to measure body movement and a video game to provide visual feedback. Ten female subjects (mean age: 60.0 ± 5.2 years old; mean BMI: 21.4 ± 1.9) with adult degenerative scoliosis (mean major Cobb's angle: 38.1° ± 22.7°) participate in a 6-week postural training programme with three one-hour postural training sessions a week. Eleven body alignment measurements of their perceived "ideal" sitting and standing postures are obtained before and after each training session to evaluate the effectiveness of postural learning with the game. The participants learn to sit and stand with increased sagittal alignment with a raised chest and more retracted head position. The forward shift of their head and upper body is significantly reduced after each training session. Although this immediate effect only partially sustained after the 6-week program, the participants learned to adjust their shoulder and pelvis level for a better lateral alignment in standing. The proposed postural training system, which is presented as a gameplay with real-time visual feedback, can effectively help players to improve their postures. This pilot feasibility study explores the development and initial assessment of a motion-based video game designed for postural training in older adults with adult degenerative scoliosis, and demonstrates the usability and benefits of active gameplay in motor training.

Results of the Surgical Approach of Idiopathic Scoliosis in Adolescents and Postoperative Quality of Life: Systematic Literature Review

Adolescent idiopathic scoliosis is considered the most severe and common spinal deformity, affecting children and adolescents still in the neuropsychomotor development phase before they reach skeletal maturity. This study aimed to evaluate the surgical approach to adolescent idiopathic scoliosis (AIS), considering the results associated with the reduction of pathological curvature, pulmonary function, and repercussions on the quality of life of adolescents undergoing such treatment. Systematic literature review, with a quantitative and qualitative approach to the data collected, structured according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), carried out in the databases linked to the Medical Literature Analysis and Retrieval System Online (MEDLINE) and Latin American and Caribbean Health Sciences Literature (LILACS). The total sample of the studies was 638 adolescents with AIS, with a mean age of 14.93 years ± 1.24. The mean correction of the main pathological curvature in the studies was 55.06% ± 12.24. In all of the selected studies using posterior spinal fusion to correct AIS, there was a significant reduction in pathological curvatures (> 49%), and the recurrence of curvature in none of the studies exceeded a pathological gain of more than 5%. As for lung function, the studies showed significant increases in forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) in patients with severe AIS, and no pulmonary function losses were reported after surgery to correct AIS.

Effectiveness of Physiotherapeutic Scoliosis-Specific Exercises on 3-Dimensional Spinal Deformities in Patients With Adolescent Idiopathic Scoliosis: A Systematic Review and Meta-analysis

OBJECTIVE

To investigate the effects of physiotherapeutic scoliosis-specific exercises (PSSE) on coronal, horizontal, and sagittal deformities of the spine in adolescent idiopathic scoliosis (AIS) as well as how curve severity, intervention duration, and intervention type could modify these effects.

DATA SOURCES

Data sources included PubMed, Web of Science, Embase, Cochrane Library, and Scopus databases, which were searched from their inception to September 5, 2023.

STUDY SELECTION

Clinical controlled trials reporting the effects of PSSE on the Cobb angle, angle of trunk rotation (ATR), thoracic kyphosis (TK), or lumbar lordosis in patients with AIS aged 10-18 years. The experimental groups received PSSE; the control groups received standard care (observation or bracing) or conventional exercise such as core stabilization exercise, Pilates, proprioceptive neuromuscular facilitation, and other nonspecific exercises.

DATA EXTRACTION

Two researchers independently extracted key information from eligible studies. The quality of the studies was assessed using the Cochrane Handbook version 5.1.0 risk of bias assessment and the JBI Center for Evidence-Based Health Care (2016) of quasi-experimental research authenticity assessment tool. The level and certainty of evidence were rated according to the Grading of Recommendations, Assessment, Development, and Evaluation framework. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. The protocol for this study was registered in PROSPERO (CRD42023404996).

DATA SYNTHESIS

Twelve randomized controlled trials (RCTs) and 5 non-RCTs were meta-analyzed separately. The results indicated that compared with other nonsurgical management, PSSE significantly improved the Cobb angle, ATR, and TK, whereas the lumbar lordosis improvement was not statistically significant. Additionally, the efficacy of PSSE on Cobb angle was not significant in patients with curve severity ≥30° compared with controls. Nevertheless, the pooled effect of PSSE on Cobb angle was not significantly modified by intervention duration and intervention type and that on ATR was not significantly modified by intervention duration. The overall quality of evidence according to Grading of Recommendations, Assessment, Development, and Evaluation was moderate to low for RCT and very low for non-RCT.

CONCLUSIONS

PSSE exhibited positive benefits on the Cobb angle, ATR, and TK in patients with AIS compared with other nonsurgical therapies. In addition, the effectiveness of PSSE may be independent of intervention duration and intervention type but may be influenced by the initial Cobb angle. However, more RCTs are needed in the future to validate the efficacy of PSSE in moderate AIS with a mean Cobb angle ≥30°. Current evidence is limited by inconsistent control group interventions and small sample size of the studies.

Critical review of the evidence for Vojta Therapy: a systematic review and meta-analysis

Introduction

It is essential to link the theoretical framework of any neurophysiotherapy approach with a detailed analysis of the central motor control mechanisms that influence motor behavior. Vojta therapy (VT) falls within interventions aiming to modify neuronal activity. Although it is often mistakenly perceived as exclusively pediatric, its utility spans various functional disorders by acting on central pattern modulation. This study aims to review the existing evidence on the effectiveness of VT across a wide range of conditions, both in the adult population and in pediatrics, and analyze common therapeutic mechanisms, focusing on motor control modulation.

Aim

The goals of this systematic review are to delineate the existing body of evidence concerning the efficacy of Vojta therapy (VT) in treating a broad range of conditions, as well as understand the common therapeutic mechanisms underlying VT with a specific focus on the neuromodulation of motor control parameters.

Methods

PubMed, Cochrane Library, SCOPUS, Web of Science, and Embase databases were searched for eligible studies. The methodological quality of the studies was assessed using the PEDro list and the Risk-Of-Bias Tool to assess the risk of bias in randomized trials. Methodological quality was evaluated using the Risk-Of-Bias Tool for randomized trials. Random-effects meta-analyses with 95% CI were used to quantify the change scores between the VT and control groups. The certainty of our findings (the closeness of the estimated effect to the true effect) was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE).

Results

Fifty-five studies were included in the qualitative analysis and 18 in the meta-analysis. Significant differences in cortical activity (p = 0.0001) and muscle activity (p = 0.001) were observed in adults undergoing VT compared to the control, as well as in balance in those living with multiple sclerosis (p < 0.03). Non-significant differences were found in the meta-analysis when evaluating gross motor function, oxygen saturation, respiratory rate, height, and head circumference in pediatrics.

Conclusion

Although current evidence supporting VT is limited in quality, there are indications suggesting its potential usefulness for the treatment of respiratory, neurological, and orthopedic pathology. This systematic review and meta-analysis show the robustness of the neurophysiological mechanisms of VT, and that it could be an effective tool for the treatment of balance in adult neurological pathology. Neuromodulation of motor control areas has been confirmed by research focusing on the neurophysiological mechanisms underlying the therapeutic efficacy of VT.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=476848, CRD42023476848.

The New Modular Sforzesco Brace (Modular Italian Brace) Is as Effective as the Classical One: A Retrospective Controlled Study from a Prospective Cohort

Background: The Sforzesco brace is a very rigid push-up brace effective in adolescent idiopathic scoliosis (AIS). We recently developed a new Sforzesco brace based on modularity (the Modular Italian brace-MI brace) that could allow standardization, facilitating global expertise diffusion, increased modifiability and adaptability, and cost savings due to longer brace life. We aimed to compare the short-term results of the two braces. Methods: The retrospective study included 231 consecutive AIS treated with a MI brace (N = 53) or Sforzesco brace (N = 178). The main outcome was the first 6-month follow-up out-of-brace radiograph Cobb angle change. Secondary outcomes included the in-brace Cobb degrees and aesthetics (TRACE), prominence (angle of trunk rotation and mm), kyphosis, and lordosis changes. Results: The two groups were similar at baseline, apart from more immature patients in MI brace. Both braces reduced the Cobb angle (-6° out-of-brace; -16° in-brace) without differences between groups. All secondary outcomes improved, apart from a statistically and clinically insignificant 3° kyphosis reduction. The MI brace participants were 4.9 times more likely to improve the Cobb angle than the Sforzesco brace (OR = 4.92; 95%CI 1.91-12.64; p = 0.001). Conclusions: These findings suggest that the MI-brace can be safely used instead of the classical Sforzesco brace. However, further studies of different designs and longer follow-ups are needed to confirm these findings.

Physiotherapeutic Scoliosis-Specific Exercises (PSSE-Schroth) can reduce the risk for progression during early growth in curves below 25°: prospective control study

BACKGROUND

The main treatment aim in mild scoliosis is to prevent progression and if possible, to avoid bracing. Physiotherapeutic Scoliosis Specific Exercises (PSSE) are curve pattern specific exercises, based on 3D self-correction and activities of daily living training.

AIM

The objective of this study was to evaluate the efficacy of PSSE - Schroth, as an exclusive treatment, during the riskiest period of rapid growth.

DESIGN

Prospective control study.

SETTING

Outpatient treatment.

POPULATION

Adolescents with scoliosis.

METHODS

One hundred and sixty-three patients (148 girls,15 boys; mean age 12.6 years, Risser sign 1.1, thoracic (Th) Cobb angle 20.8° and lumbar/thoracolumbar (L/TL) Cobb angle 20.7°) performed PSSE - Schroth exercises in our clinic. They were asked to regularly attend supervised sessions and to follow a home-program at least 5 times per week. Our inclusion criteria were Cobb angle 15°-25°, Risser 0-2 and angle trunk rotation (ATR) >5°, measured by scoliometer. The outcome parameters were the Cobb angle before and after the intervention (improvement or progression were defined as angle difference more than 5°) and the number of patients that finally needed a brace. Average follow-up time was 29.4 months. Control group was consisted of 58 patients (54 girls, 4 boys; mean age 13.1 years, Risser sign 0-2, Th Cobb 19.4°, L/TL Cobb 19.2°), that were retrospectively analyzed and performed general or no exercises. Compliance was self-reported. Statistical analysis was performed by paired t-test.

RESULTS

For PSSE - Schroth group, 103 patients (63.2%) remained stable, 39 (23.9%) improved and 21 (12.9%) worsened. The success rate (87.1%) was significantly higher compared to Control group (P=0.002), where 15 subjects (25.9%) were stable and 43 (74.1%) worsened. Similarly, 16 patients (9.8%) from PSSE - Schroth group finally needed a brace, while 39 (67.2%) from control group (P=0.01).

CONCLUSIONS

PSSE - Schroth reduced the risk of progression in Adolescent Idiopathic Scoliosis (AIS) patients, during early growth. Our results are in accordance with the recently published literature, showing the effectiveness of PSSE and their superiority compared to general exercises or natural history.

CLINICAL REHABILITATION IMPACT

Scoliosis specific exercises can be the first step of scoliosis treatment in mild curves, to avoid progression and bracing.

The Relationship Between Compliance of Physiotherapeutic Scoliosis Specific Exercises and Curve Regression With Mild to Moderate Adolescent Idiopathic Scoliosis

STUDY DESIGN

Retrospective Case-control Study.

OBJECTIVES

To determine the requisite exercise compliance (EC) of physiotherapeutic scoliosis-specific exercise (PSSE) for achieving curve regression; to analyze whether the apical translation (AT), apical wedging (AW), and apical rotation (AR) of the major curve improve with regression effect.

METHODS

Between 2019 and 2021, a total of 763 patients undertook a 6-month PSSE treatment. This resulted 426 compliable and 302 uncompliable patients remained available for analysis. For compliable patients, 213 with curve regression and 213 age-/sex-matched with curve stabilization/deterioration at the 6-month, were eligible for regression analysis to detect the relationship between EC and regression effect at the 6-month; receiver operating characteristic (ROC) curve analysis and Youden's index were applied to identify the threshold of EC leading to curve regression at the 6-month. The AT, AW, and AR of the major curve were compared before and after 6-month PSSE to investigate the radiographic parameters that improved with regression effect.

RESULTS

EC was correlated with regression effect (odds ratio: 19.9, 95% confidence interval: 11.3-35.0, P < .001) and the cutoff threshold of EC was 4.4 h/week for 6 months to realize such an effect. AT was improved by 47.6% with curve regression, in which 152 cases remained curve regression and no case progressed into the operative threshold at the 1.5- to 2-year.

CONCLUSIONS

A 6-month PSSE protocol of 4.4 hours per week was potentially leading to curve regression in treating mild to moderate scoliosis. An improvement in AT of the major curve was observed with the regression effect.

Therapeutic exercises for idiopathic scoliosis in adolescents

BACKGROUND

Adolescent idiopathic scoliosis (AIS) is a pathology that changes the three-dimensional shape of the spine and trunk. While AIS can progress during growth and cause cosmetic issues, it is usually asymptomatic. However, a final spinal curvature above the critical threshold of 30° increases the risk of health problems and curve progression in adulthood. The use of therapeutic exercises (TEs) to reduce the progression of AIS and delay or avoid other, more invasive treatments is still controversial.

OBJECTIVES

To evaluate the effectiveness of TE, including generic therapeutic exercises (GTE) and physiotherapeutic scoliosis-specific exercises (PSSE) in treating AIS, compared to no treatment, other non-surgical treatments, or between treatments.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, four other databases, and two clinical trials registers to 17 November 2022. We also screened reference lists of articles.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing TE with no treatment, other non-surgical treatments (braces, electrical stimulation, manual therapy), and different types of exercises. In the previous version of the review, we also included observational studies. We did not include observational studies in this update since we found sufficient RCTs to address our study aims.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodology. Our major outcomes were progression of scoliosis (measured by Cobb angle, trunk rotation, progression, bracing, surgery), cosmetic issues (measured by surface measurements and perception), and quality of life (QoL). Our minor outcomes were back pain, mental health, and adverse effects.

MAIN RESULTS

We included 13 RCTs (583 participants). The percentage of females ranged from 50% to 100%; mean age ranged from 12 to 15 years. Studies included participants with Cobb angles from low to severe. We judged 61% of the studies at low risk for random sequence generation and 46% at low risk for allocation concealment. None of the studies could blind participants and personnel. We judged the subjective outcomes at high risk of performance and detection bias, and the objective outcomes at high risk of detection bias in six studies and at low risk of bias in the other six studies. One study did not assess any objective outcomes. Comparing TE versus no treatment, we are very uncertain whether TE reduces the Cobb angle (mean difference (MD) -3.6°, 95% confidence interval (CI) -5.6 to -1.7; 2 studies, 52 participants). Low-certainty evidence indicates PSSE makes little or no difference in the angle of trunk rotation (ATR) (MD -0.8°, 95% CI -3.8 to 2.1; 1 study, 45 participants), may reduce the waist asymmetry slightly (MD -0.5 cm, 95% CI -0.8 to -0.3; 1 study, 45 participants), and may result in little to no difference in the score of cosmetic issues measured by the Spinal Appearance Questionnaire (SAQ) General (MD 0.7 points, 95% CI -0.1 to 1.4; 1 study, 16 participants). PSSE may result in little to no difference in self-image measured by the Scoliosis Research Society - 22 Patient Questionnaire (SRS-22) (MD 0.3 points, 95% CI -0.3 to 0.9; 1 study, 16 participants) and improve QoL slightly measured by SRS-22 Total score (MD 0.3 points, 95% CI 0.1 to 0.4; 2 studies, 61 participants). Only Cobb angle results were clinically meaningful. Comparing PSSE plus bracing versus bracing, low-certainty evidence indicates PSSE plus bracing may reduce Cobb angle (-2.2°, 95% CI -3.8 to -0.7; 2 studies, 84 participants). Comparing GTE plus other non-surgical interventions versus other non-surgical interventions, low-certainty evidence indicates GTE plus other non-surgical interventions may reduce Cobb angle (MD -8.0°, 95% CI -11.5 to -4.5; 1 study, 80 participants). We are uncertain whether PSSE plus other non-surgical interventions versus other non-surgical interventions reduces Cobb angle (MD -7.8°, 95% CI -12.5 to -3.1; 1 study, 18 participants) and ATR (MD -8.0°, 95% CI -12.7 to -3.3; 1 study, 18 participants). PSSE plus bracing versus bracing alone may make little to no difference in subjective measurement of cosmetic issues as measured by SAQ General (-0.2 points, 95% CI -0.9 to 0.5; 1 study, 34 participants), self-image score as measured by SRS-22 Self-Image (MD 0.1 points, 95% CI -0.3 to 0.5; 1 study, 34 participants), and QoL measured by SRS-22 Total score (MD 0.2 points, 95% CI -0.1 to 0.5; 1 study, 34 participants). None of these results were clinically meaningful. Comparing TE versus bracing, we are very uncertain whether PSSE allows progression of Cobb angle (MD 2.7°, 95% CI 0.3 to 5.0; 1 study, 60 participants), changes self-image measured by SRS-22 Self-Image (MD 0.1 points, 95% CI -1.0 to 1.1; 1 study, 60 participants), and QoL measured by SRS-22 Total score (MD 3.2 points, 95% CI 2.1 to 4.2; 1 study, 60 participants). None of these results were clinically meaningful. Comparing PSSE with GTE, we are uncertain whether PSSE makes little or no difference in Cobb angle (MD -3.0°, 95% CI -8.2 to 2.1; 4 studies, 192 participants; very low-certainty evidence). PSSE probably reduces ATR (clinically meaningful) (MD -3.0°, 95% CI -3.4 to -2.5; 2 studies, 138 participants). We are uncertain about the effect of PSSE on QoL measured by SRS-22 Total score (MD 0.26 points, 95% CI 0.11 to 0.62; 3 studies, 168 participants) and on self-image measured by SRS-22 Self-Image and Walter Reed Visual Assessment Scale (standardised mean difference (SMD) 0.77, 95% CI -0.61 to 2.14; 3 studies, 168 participants). Further, low-certainty evidence indicates that 38/100 people receiving GTE may progress more than 5° Cobb versus 7/100 receiving PSSE (risk ratio (RR) 0.19, 95% CI -0.67 to 0.52; 1 study, 110 participants). None of the included studies assessed adverse effects.

AUTHORS' CONCLUSIONS

The evidence on the efficacy of TE is currently sparse due to heterogeneity, small sample size, and many different comparisons. We found only one study following participants to the end of growth showing the efficacy of PSSE over TE. This result was weakened by adding studies with short-term results and unclear preparation of treating physiotherapists. More RCTs are needed to strengthen the current evidence and study other highly clinically relevant outcomes such as QoL, psychological and cosmetic issues, and back pain.

Development, validity and reliability of patient perception of scoliosis-specific physiotherapy (physio-is) questionnaire

PURPOSE

To develop a questionnaire for adolescent idiopathic scoliosis (AIS) patients undergoing physiotherapeutic scoliosis-specific exercises (PSSE) and to evaluate its content validity, structural validity, and reliability.

METHODOLOGY

Seven PSSE treatment experts checked the content validity of the Patient's Perception of Scoliosis-Specific Physiotherapy Questionnaire (Physio-IS). For each Physio-IS item, the content validity indexes must be ≥ 90%. Regarding structural validity and reliability 52 adolescents (ages 10-17) with AIS completed the questionnaire. Structural validity was assessed through exploratory factor analysis. Reliability was verified through internal consistency.

RESULTS

Physio-IS content was validated in three evaluation rounds, obtaining 100% expert agreement. About structural validity we identified four domains (cumulative explained variance = 68.2%): (1) specific knowledge (seven questions on understanding their scoliosis condition); (2) social repercussion (five questions about social relationship implications); (3) pain (two questions about scoliosis-associated pain); and (4) associated concern (apprehension/expectations regarding the future). The Physio-IS demonstrated very good internal consistency (Cronbach's alpha = 0.76-0.92).

CONCLUSION

The Physio-IS is a valid and reliable tool for assessing AIS patients undergoing PSSE and helping physiotherapists identify aspects requiring more attention, thus facilitating intervention strategies, as knowing the patient's perception of their condition or treatment is fundamental to AIS treatment success.

Effects of Pilates exercises on spine deformities and posture: a systematic review

BACKGROUND

Pilates is becoming increasingly popular amongst a wide range of people and is gaining more attention. It is also an effective means of physical rehabilitation. The aim of this systematic review is to explore the effects of Pilates on spinal deformity and posture.

METHOD

This systematic review was conducted using four recognised academic and scientific databases (Scopus, Web of Science, PubMed and Cochrane) to identify articles that met the inclusion criteria. The secondary search used the Google Scholar and the Science Direct search engines. The search for articles for this review began in July 06, 2023 and was concluded on February 01, 2024. The search process for this study was documented using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020). The PEDro scale was used to assess the internal validity and data statistics of the studies included in this systematic review and to evaluate the quality of the studies.

RESULTS

The systematic review included nine studies that met the inclusion criteria from the 651 studies retrieved, involving a total of 643 participants. The PEDro scale scores of the studies included in this systematic review ranged from 3 to 8. The intervention was in the form of Pilates or Pilates combined exercises. The studies included in this review used outcome measures of Cobb angle, angle of trunk rotation (ATR), range of motion (ROM), chest expansion, Scoliosis Research Society Questionnaire (SRS-22r) and postural assessment. Research has shown that Pilates is effective in correcting spinal deformities and posture, as well as improving quality of life, pain relief, function and fitness.

CONCLUSIONS

This systematic review provide substantial evidence that Pilates has a positive impact on improving spinal deformity and posture. However, more research is needed to validate whether Pilates can be used effectively as a physical therapy for spinal deformity rehabilitation. Pilates has considerable potential for public health interventions.

The Immediate Effect of Hanging Exercise and Muscle Cylinder Exercise on the Angle of Trunk Rotation in Adolescent Idiopathic Scoliosis

(1) Background: Semi-hanging and muscle cylinder exercises have been defined as scoliosis-specific corrective exercises. The aim of this study was to evaluate the immediate effect of muscle cylinder and semi-hanging exercises on the angle of trunk rotation in patients with adolescent idiopathic scoliosis (AIS). (2) Methods: Twenty-seven patients with AIS with a mean age of 18.6 years were retrospectively analyzed. The angle of trunk rotation (ATR) values were measured before and after performing semi-hanging and standing muscle cylinder exercises. Both exercises were performed for three to five respiratory cycles. The semi-hanging exercise was performed first, followed by the muscle cylinder exercise, in this order, in all participants. For statistical analysis, the Wilcoxon signed-rank test was used to analyze ATR changes after the exercises, and the Kruskal-Wallis test was used to compare ATR changes according to the main curve location. (3) Results: The thoracic, thoracolumbar and lumbar maximum ATR values were significantly increased after the semi-hanging exercise (p < 0.001) and decreased after the muscle cylinder exercise (p < 0.001). The ATR change was greater in the lumbar region than in the thoracic and thoracolumbar regions. (4) Conclusion: The results of this study of a small group of patients emphasized that one of the scoliosis-specific corrective exercises, the standing muscle cylinder exercise, improved ATR, while the other, the semi-hanging exercise, worsened ATR in patients with AIS. It is recommended that each scoliosis-specific corrective exercise be evaluated and redesigned to maximize the three-dimensional corrective effect, considering the biomechanics of the spine and the pathomechanics of scoliosis.

The Improvement of Trunk Muscle Endurance in Adolescents with Idiopathic Scoliosis Treated with ScoliBrace® and the ScoliBalance® Exercise Approach

The impact of scoliosis bracing combined with physiotherapeutic scoliosis-specific exercises (PSSE) on trunk muscle endurance in adolescents with idiopathic scoliosis is unknown. ScoliBrace®, a rigid, three-dimensional, over-corrective thoraco-lumbar-sacral orthosis (TLSO), and ScoliBalance®, a PSSE program, were used to treat adolescent idiopathic scoliosis (AIS) patients. A retrospective study of the trunk muscle endurance of 33 AIS patients who received ScoliBrace® and ScoliBalance® was conducted. The patients were treated with ScoliBrace® and an individualized ScoliBalance® program. Trunk extensor muscle endurance (TE) and abdominal muscle endurance (AE) tests were performed at initial assessment and then at averages of 6.6 and 24.4 weeks of treatment. The data were analyzed using the Wilcoxon signed-rank test, Stata version 15.1. The participants were aged 13.24 years (SD = 1.64) with a mean Cobb angle of 38.97° (SD = 9.49°). TE improved significantly (p < 0.001) at both short- and medium-term intervals using ScoliBalance® and ScoliBrace® in the AIS patients. AE also showed significant improvement between baseline and short-term follow-up, with non-significant improvement at medium-term follow-up. Overall, trunk muscle endurance showed improvement in the AIS patients using ScoliBrace® and ScoliBalance®. Future research is required to determine the individual and combined effects of each treatment. However, it seems likely that trunk muscle endurance will not deteriorate in AIS patients with this combined treatment.

Global research hotspots and trends in non-surgical treatment of adolescent idiopathic scoliosis over the past three decades: a bibliometric and visualization study

Background

In recent years, research on the non-surgical treatment of AIS has been increasingly conducted. To the best of our knowledge, this field doesn't yet have a comprehensive and structured pulse combing analysis. In order to provide inspiration and resources for subsequent researchers, we thus reviewed the literature studies on the non-surgical treatment of AIS from the previous thirty years and highlighted the hotspots and frontiers of research in this field.

Methods

Main using Citespace 6.1 software, the data from the core dataset of the WOS database pertaining to the non-surgical management of AIS from 1990 to 2022 was gathered, displayed, and analyzed.

Results

839 papers in all were included in the literature. With 215 papers, the USA came in first place. Chinese Univ Hong Kong ranked first with 32 papers. Research hotspots are adolescent idiopathic spondylitis, Schroth-based physiotherapy-specific exercise efficacy, curve development, Cobb angle, TLSO brace-based clinical efficacy, quality of life, reliability, health-related quality of life questionnaires, finite element biomechanical models, follow-up, and clinical guidelines.

Conclusion

There aren't many studies that compare the clinical effectiveness of various non-surgical treatments, and because of variations in inclusion eligibility standards and outcome measures, these studies cannot be directly compared. In addition, the inconsistency of existing growth potential and progression risk assessment systems further affects comparative studies of clinical efficacy; it is recommended to establish primary assessment indicators centered on patient treatment outcomes (including appearance, disability, pain, and quality of life), as well as standardized scoliosis progression risk assessment criteria.

A Questionnaire of Physiotherapeutic Specific Exercises of Scoliosis-QPSSE

STUDY DESIGN

Creating and psychometric testing of a new QoL Questionnaire about Physiotherapeutic Specific Exercises of Scoliosis (Questionnaire of Physiotherapeutic Specific Exercises of Scoliosis-QPSSE).

PURPOSE

The purpose of this study is to create a reliable and valid questionnaire for patients suffering from mild and moderate adolescent idiopathic scoliosis (AIS) who have been treated with Physiotherapeutic Specific Exercises of Scoliosis (PSSE) in order to evaluate their quality of life.

MATERIALS AND METHODS

The developed questionnaire was based on a thorough literature review as well as on authors' experience. It consists of 53 questions, of which 37 have a positive meaning, 15 have a negative meaning, and 1 is a multiple choice question; additionally, there are 6 "open" questions. Except for the multiple choice question, all other questions are answered on a Likert scale ranging from 1 to 5 points. Five represents a positive meaning or very positive one, whereas one stands for a negative meaning or none at all. Questions were developed by the authors who subsequently categorized the 53 questions into the following eight domains: physical functioning, self-image, Physiotherapeutic Scoliosis-Specific Exercises (PSSEs), psychosocial functioning, cognitive functioning, compliance, motivation, and pain. A pilot study was conducted so that we could calculate Cronbach's Alpha based on the outcome. Due to the COVID-19 pandemic, the authors worked through the Zoom online platform to structure the questionnaire.

RESULTS

Pearson's correlation coefficient was used for all correlations evaluated. P values of less than 0.05 were considered to be significant. Internal consistency was evaluated with Cronbach's Alpha. Although there were very few missing values, accounting for 0.78% of the total values of the questionnaire, the expectation maximization likelihood algorithm was used to impute data. IBM® SPSS® Statistics Software v.25 was used for the analysis. Cronbach's Alpha coefficients for the overall score were 0.84.

CONCLUSIONS

This original QPSSE was found to be a reliable and valid tool for AIS treated conservatively with PSSE and for the patients' clinicians.

Exercise therapy for adolescent idiopathic scoliosis rehabilitation: a bibliometric analysis (1999-2023)

Background

Among the conservative treatments for rehabilitation of adolescent idiopathic scoliosis (AIS), exercise therapy has attracted a large number of studies as its advantages of good clinical effect, high operability, high compliance, few side effects and low cost. We conduct a bibliometric analysis of previous research to identify prevalent areas of study and inform research for the future directions in this paper.

Methods

Relevant publications and reviews were collected using the Science Citation Index Expanded from the Web of Science Core Collection. Information from the included studies was analyzed systematically using VOSviewer and Citespace software to identify patterns regarding publications, keywords, authors, citations, countries, institutions and journals.

Results

A total of 172 articles published from 1999 to 2023 were identified. Over the last decade, the number of publications has gradually increased, reaching a peak of 21 publications in 2021. China, North America and Western European countries and institutions are leading the way as far as the quantity of publications and the total number of citations are concerned. The current areas of focus are the efficacy of exercise therapy in relation to enhancing the quality of life of adolescents during rehabilitation.

Conclusions

This is the first bibliometric analysis that provides a comprehensive review of the research trends and advances in exercise therapy for the rehabilitation of AIS. The study identifies latest research frontiers and hot directions, providing a valuable reference for scholars in the field of exercise therapy.

Core Stabilization Exercises vs. Schroth's Three Dimensional Exercises to Treat Adolescent Idiopathic Scoliosis: A Systematic Review

Background

Adolescent idiopathic scoliosis (AIS) is one of the most prevalent spinal abnormalities, appearing far into puberty. Schroth's exercises (SE) and core-stabilization exercises (CE) have become very prominent among the specialized and general methods to scoliosis treatment. However, their effects are still unclear and there is insufficient evidence of superiority between them. Therefore, we aimed to evaluate and compare the effectiveness of these methods on Cobb angles (CA) in AIS.

Methods

A systematic review was performed on SE and CE papers. The databases included PubMed, Scopus, MEDLINE, Cochrane Library, CINAHL, and Google Scholar from January 2005 to June 2022. The physiotherapy evidence database (PEDro) scale assessed the quality and provided internal validity and the statistical information of the papers.

Results

After screening 410 papers, nine papers (SE=5, CE=3 and SE vs. CE=1), with 339 participants, were admitted for review (PEDro=6). Among them, three (SE=moderate evidence) and two papers (CE=limited evidence) reported clinically significant reductions in CA>5°, alone or compared to control or other exercise methods, while only one paper (very limited evidence) showed the relative superiority of SE (-7.16°) compared to CE (-3.27°). However, three papers did not show clinically significant results (CA<5°).

Conclusion

Moderate and limited evidence suggests that both SE and CE can effectively improve CA, respectively. There is very limited evidence to suggest that SE is more effective than CE in treating AIS. Thus, the definitive answers to the questions, especially concerning the superiority between these two methods, remained unclear. Further high-quality studies must be conducted in the future.

Electromyography of paraspinal muscles during self-corrective positions in adolescent idiopathic scoliosis

BACKGROUND

Self-corrective exercise is commonly used in the training protocol of patients with adolescent idiopathic scoliosis (AIS). The muscle activation pattern during symmetrical and overcorrection exercises is then explored to guide the treatment.

OBJECTIVE

To compare the paraspinal muscle activity during three self-corrective positions and the habitual standing in AIS.

METHODS

Thirty-three adolescents with double curved scoliosis were examined. The curve type and Cobb's angle were determined from their whole spine X-ray. They adopted habitual standing, symmetrical correction and two overcorrected positions (O1 and O2). The surface electromyography (EMG) was monitored on both sides of paraspinal muscles at the apex areas of scoliotic curves. The EMG ratio between sides was inferred as the corrective effect.

RESULTS

All three self-correction positions produced greater EMG ratios compared with the habitual standing. The greatest EMG ratios were observed during the O1 position at the thoracic curve and the habitual standing at the lumbar curve. Participants with different subtypes of curves exhibited similar patterns of EMG ratios.

CONCLUSION

From the biomechanical viewpoint, all three self-corrective positions possibly provided therapeutic effects for the scoliotic body regardless of the subtype of scoliosis curves. The O1 position seemed to be most effective for the adjusting activation of thoracic paraspinal muscles. The symmetrical corrective position is otherwise recommended for adjusting the lumbar muscle activation.

Outcomes of 12 Weeks of Schroth and Asymmetric Spinal Stabilization Exercises on Cobb Angle, Angle of Trunk Rotation, and Quality of Life in Adolescent Boys with Idiopathic Scoliosis: A Randomized-controlled Trial

Objectives

The available evidence on the efficiency of well-known Schroth's exercises (SE) for correcting adolescent idiopathic scoliosis (AIS) is limited, especially in combination with the asymmetric spinal stabilization exercises (ASSE) method. Therefore, we hypothesized that, first, there is no difference in the efficiency of the combined exercises (SE+ASSE) and SE alone in improving Cobb angle, angle of trunk rotation (ATR), and quality of life (QoL) in AIS. Second, there is no difference in the efficiency of SE and no intervention on corresponding variables in treating AIS.

Methods

This randomized controlled trial (RCT) consisted of 40 patients with mild AIS (10-18-year-old boys) divided into three groups: SE (n=15), SE+ASSE (n=15), and a waitlist control group (n=10). For 12 weeks (three days a week), both experimental groups performed SE, the combined group additionally received ASSE, and the control group received no intervention. The assessment included Cobb angle (photogrammetry), ATR (Adam's test), and QoL (Scoliosis Research Society-22 questionnaire).

Results

It was found that Cobb angle, ATR, and QoL improved significantly in the combined SE+ASSE group (Cobb=16.45° to 9.01°; ATR=4.93° to 1.33°) compared to the SE group (P<.001). In addition, the SE group showed significant amelioration in the mentioned variables (Cobb=15.09° to 9.77°; ATR=4.23° to 2.17°) compared to the control group (P<.001), whereas the control group remained almost unchanged.

Conclusion

Based on the obtained results, the combination of SE and ASSE provided more benefits than SE alone, and the SE results were efficient compared to the no-intervention group regarding the correction of scoliosis and related problems. However, patients with moderate to severe scoliosis should also be investigated in longer treatment periods in future.

Personal and Clinical Determinants of Brace-Wearing Time in Adolescents with Idiopathic Scoliosis

Adolescent idiopathic scoliosis (AIS) is a three-dimensional spine and trunk deformity. Bracing is an effective treatment for medium-degree curves. Thermal sensors help monitor patients' adherence (compliance), a critical issue in bracing treatment. Some studies investigated adherence determinants but rarely through sensors or in highly adherent cohorts. We aimed to verify the influence of personal and clinical variables routinely registered by physicians on adherence to brace treatment in a large cohort of consecutive AIS patients from a highly adherent cohort. We performed a cross-sectional study of patients consecutively recruited in the last three years at a tertiary referral institute and treated with braces for one year. To ensure high adherence, for years, we have provided specific support to brace treatment through a series of cognitive-behavioural interventions for patients and parents. We used iButton thermal sensor systematic data collection to precisely analyse the real brace-wearing time. We included 514 adolescents, age 13.8 ± 1.6, with the worst scoliosis curve of 34.5 ± 10.3° Cobb. We found a 95% (95CI 60-101%) adherence to the brace prescription of 21.9 ± 1.7 h per day. Determinants included gender (91% vs. 84%; females vs. males) and age < 14 years (92% vs. 88%). Brace hours prescription, BMI, and all clinical variables (worst curve Cobb degrees, angle of trunk rotation, and TRACE index for aesthetics) did not influence adherence.

Spinal Orthosis in Adolescent Idiopathic Scoliosis: An Overview of the Braces Provided by the National Health Service in Italy

Adolescent idiopathic scoliosis (AIS) is a lateral, rotated curvature of the spine. It is a 3-dimensional deformity that arises in otherwise healthy children at or around puberty. AIS is the most common form of scoliosis in the pediatric population. The etiology is multifactorial, including genetic and environmental factors. The incidence is roughly equal between males and females, while there is a higher risk of progression in females. Guidelines for AIS treatment identify three levels of treatment: observation, physiotherapy scoliosis-specific exercises, and braces. In this paper, we carried out a review of the scientific literature about the indication and success rates of the braces provided for free by the National Health Service in Italy (SSN). Despite a general consensus on the efficacy of rigid bracing treatment and its use in AIS, an important heterogeneity about the treatment is present in the scientific literature, demonstrating a high degree of variability. The overall success rate of the braces provided by the SSN is high, suggesting an important therapeutic role in the treatment of AIS. Robust guidelines are needed to ensure uniform and effective treatments.

How Schroth Therapists Vary the Implementation of Schroth Worldwide for Adolescents with Idiopathic Scoliosis: A Mixed Methods Study

(1) Background: Schroth is a type of physiotherapeutic scoliosis specific exercise (PSSE) prescribed to adolescents with idiopathic scoliosis (AIS). Studies have investigated the effectiveness of Schroth but are yet to elucidate how Schroth is applied clinically and the factors that influence their prescription. (2) Methods: A mixed methods design was used comprising an anonymous survey and semi-structured interviews of Schroth therapists who treated AIS and who were publicly listed on the Barcelona Scoliosis Physical Therapy School or the International Schroth 3-dimensional Scoliosis Therapy School websites. The survey included 64 questions covering demographics, session and treatment characteristics, and whether therapists included other treatment modalities in their clinical practice. A convenience sample of survey participants were invited to participate in a semi-structured interview to further explore the factors that influenced their prescription of Schroth for AIS. Results from the survey were analyzed descriptively (n, %), whereas inductive thematic analysis was used for the interviews. (3) Results: of the 173 survey respondents (18% response rate), most were from Europe and North America (64.0%), female (78.6%), physiotherapists (96.0%), and worked in private settings (72.3%). Fifty-two per cent of participants used other types of PSSE as an adjunct to Schroth, the Scientific Exercise Approach to Scoliosis (SEAS) being the most frequently used (37.9%). Non-PSSE methods were used 'at some point' as an adjunct by 98.8% of participants, including massage and other soft tissue techniques (80.9%), Pilates (46.6%), and Yoga (31.5%). The Schroth techniques used by all survey respondents included breathing and pelvic corrections. Seven participants were interviewed, but data saturation was achieved after only four interviews. Thematic analysis revealed four, inter-related broad themes describing the factors that influenced Schroth prescription for AIS: (1) the adolescent as a whole, including physical, emotional and mental characteristics, and patient goals, (2) family, including parent relationship with the adolescent and the motivation of parents in regard to Schroth, (3) the systems within which the treatment was being offered, such as vicinity to the clinic and the presence of financial insurance support, and (4) therapist characteristics, such as their training and experience. (4) Conclusions: Schroth therapists worldwide use a variety of adjunctive methods to treat AIS. Therapists prescribing Schroth exercises to AIS consider the complex interplay of intra-, inter- and extra-personal factors in clinical practice. These considerations move beyond the three components of evidence-based practice of research, patient preferences, and clinical expertise, towards a systems-based reflection on exercise prescription.

Effects of Pilates exercises on idiopathic scoliosis: a scoping review of the literature

PURPOSE

Scoliosis is a deformity involving changes in three planes. These changes include lateral curvature in the frontal plane, changes in physiological thoracic kyphosis and lumbar lordosis angles in the sagittal plane, and rotation of the vertebrae in the transverse plane. The aim of this scoping review was to review and summarize the available literature to determine whether Pilates exercises are an effective treatment for scoliosis.

METHODS

The Cochrane Library (reviews, protocols, trials), PubMed, Web of Science, Ovid, Scopus, PEDro, Medline, CINAHL (EBSCO), ProQuest, and Google Scholar electronic databases were used to search for published articles from inception to February 2022. All the searches included English language studies. Keywords were determined as "scoliosis and Pilates" or "idiopathic scoliosis and Pilates", "curve and Pilates", "spinal deformity and Pilates."

RESULTS

Seven studies were included; one study was a meta-analysis study, three studies compared Pilates and Schroth exercises, and three applied Pilates exercises in combined therapy. The studies included in this review used outcome measurements of Cobb angle, ATR, chest expansion, SRS-22r, posture assessment, weight distribution, and psychological factors such as depression.

CONCLUSIONS

The results of this review suggest that the level of evidence regarding the effect of Pilates exercises on scoliosis-related deformity is very limited. Pilates exercises can be applied to reduce asymmetrical posture in individuals with mild scoliosis with reduced growth potential and progression risk.

A United States multi-site randomized control trial of Schroth-based therapy in adolescents with mild idiopathic scoliosis

PURPOSE

The purpose of this study was to determine the feasibility and efficacy of a United States multi-site randomized control trial (RCT) of the Schroth-based therapy program in Risser 0 patients with mild adolescent idiopathic scoliosis (AIS) curves.

METHODS

Six sites enrolled 98 Risser 0 patients with single AIS curves between 12° and 24°. Patients were randomized to Exercise:Control group in a 2:1 ratio. Exercise group patients were instructed on the Schroth-based method and a home exercise program of 75 min/week for 1 year.

RESULTS

Enrollment across 6 institutions averaged 2.2 patients per month over 45 months. Patient attrition was 42% after 1 year (41/98) and 52% after 2 years (51/98). Exercise group patients were significantly younger (11.6 vs 12.5 years) without differences in the baseline Cobb angle (16.2° vs 17.1°). Self-reported exercise adherence averaged 82% at 6 months and 63% at 1 year (n = 35). A significantly lower frequency of patients was braced in the Exercise group after 1 year (26% vs 55%, p = 0.03) but not after 2 years (48% vs 63%, p = 0.31). Curve magnitude changes between groups were not significant after 1 and 2 years.

CONCLUSION

Performing a multi-site RCT for mild AIS in the United States is challenging with slow enrollment and high attrition. Young patients with small curves have difficulty adhering to the intensive demands of Schroth-based therapy.

Bridging Motor Learning Principles with Physiotherapy Specific Scoliosis Exercises: a Perspective Article

AIM

This perspective paper illustrates the usefulness of explicitly integrating motor learning terminology with evolving therapeutic approaches. Physiotherapy specific scoliosis exercises (PSSEs) include a growing number of approaches to scoliosis management and serve as an example of this integration.

METHODS

Three quintessential patient cases (a young hypermobile adolescent, a post-pubescent teen, and an adult with childhood diagnosis of scoliosis) serve to contrast the clinical decision-making process for a PSSE plan of care when organized within a motor learning framework.

CONCLUSIONS AND IMPLICATIONS

As intervention approaches evolve, aligning the unique terminologies from different schools of thought with motor learning constructs would provide a common language for clinicians, academics and researchers to facilitate comparison of approaches and organize intervention care plans. Linking a motor learning framework and terminology to PSSE may facilitate comparison of PSSE treatment approaches by clinicians, academics, and researchers, as well as advance the global quality of care for patients with scoliosis.

Effects of 3D Postural Correction and Abdominal Muscle Contraction on the Symmetry of the Transverse Abdominis and Spinal Alignment in Patients with Idiopathic Scoliosis

This study aimed to investigate the effectiveness of 3D postural correction (3DPC) using corrective cushions (CCs) and abdominal muscle contraction (AMC) on the thickness symmetry of the transversus abdominis (TrA) and spinal alignment in patients with idiopathic scoliosis (IS). In the first experiment, ultrasound measurements were taken of the TrA thickness on both the convex and concave sides of the lumbar curve in the supine position during AMC and non-AMC without 3DPC, and during AMC and non-AMC with 3DPC using CCs, in 11 IS patients. In the second experiment, 37 IS patients participated in a four-week 3DPC exercise program that aimed to maintain TrA thickness symmetry based on the results of the first experiment. The study found that TrA thickness symmetry significantly increased after 3DPC using CCs and combined with AMC (p < 0.05). Additionally, the Cobb angles and trunk rotation angles showed significant decreases, and trunk expansion showed a significant increase (p < 0.05). These results indicate that the simultaneous application of 3DPC and AMC is the most effective way to achieve TrA thickness symmetry in IS patients. Therefore, 3DPC and AMC should be considered as crucial elements in exercise interventions for IS patients.

The Effectiveness of the Schroth Best Practice Program and Chêneau-Type Brace Treatment in Adolescent Idiopathic Scoliosis: Long-Term Follow-Up Evaluation Results

BACKGROUND

Although the number of studies showing the efficacy of conservative treatment in adolescent idiopathic scoliosis has increased, studies with long-term follow-up are very limited. The aim of this study was to present the long-term effects of a conservative management method including exercise and brace in adolescent idiopathic scoliosis patients.

METHODS

This retrospective cohort study included patients with idiopathic scoliosis who presented at our department and were followed up for at least 2 years after completing the treatment. The main outcome measurements were the Cobb angle and angle of trunk rotation (ATR).

RESULTS

The cohort participants were 90.4% female, with a mean age of 11 years and the maximum Cobb angle was mean 32.1°. The mean post-treatment follow-up period was 27.8 months (range 24-71 months). The improvements after treatment in mean maximum Cobb angle (p < 0.001) and ATR (p = 0.001) were statistically significant. At the end of treatment, the maximum Cobb angle was improved in 88.1% of the patients and worsened in 11.9% compared to baseline. In the long-term follow-up evaluations, 83.3% of the curvatures remained stable.

CONCLUSIONS

The results of this study showed that moderate idiopathic scoliosis in growing adolescents can be successfully halted with appropriate conservative treatment and that long-term improvement is largely maintained.

Idiopathic Scoliosis: Novel Challenges for Researchers and Clinicians

Scoliosis is a three-dimensional deformity of the spine and trunk [...].

Application of the Schroth Method in the Treatment of Idiopathic Scoliosis: A Systematic Review and Meta-Analysis

(1) Background: Idiopathic scoliosis can be defined as a complex three-dimensional deformity of the spine and trunk, which occurs in basically healthy children. Schroth scoliosis-specific exercises have shown good results in reducing idiopathic scoliosis progression. This study aimed to critically evaluate the effect size of Schroth's method through a systematic review and meta-analysis. (2) Methods: Four databases were included in the search: PubMed, Cochrane Library, Web of Science, and Google Scholar. The following keywords were used: "Schroth exercise", "idiopathic scoliosis", "Cobb angle", "angle of trunk rotation", and "quality of life". Only articles written in English that met the following criteria were included in our study: subjects who had idiopathic scoliosis, the Schroth method was applied, and Cobb angle or angle of trunk rotation or quality of life as outcomes. (3) Results: Ten randomized controlled trials were included in this study.

Brace and Physiotherapeutic Scoliosis Specific Exercises (PSSE) for Adolescent Idiopathic Scoliosis (AIS) treatment: a prospective study following Scoliosis Research Society (SRS) criteria

BACKGROUND

A growing scientific evidence for conservative treatment of AIS has recently proved that bracing is superior to natural history. Our aim was to investigate the effectiveness of a combined treatment with brace and PSSE for AIS.

METHODS

Prospective study, following SRS research inclusion criteria (> 10 years, 25^ο - 40^ο, Risser 0-2, < 1-year post-menarche, no prior treatment). 102 consecutive patients (87 females-15 males, mean age 12.8 years, Risser 0.48, Cobb Thoracic 29.2^ο, Lumbar 27.8^ο) received treatment with Cheneau brace and PSSE. Average follow-up time was 26.4 months. A scale from A to C was used to evaluate compliance with brace and PSSE (A: full-compliant, B: partially compliant, C: non-compliant). 7 subjects dropped-out (6.8%), so finally 95 patients included for statistical analysis, using paired t-test.

RESULTS

Sixty-two patients (65.3%) remained stable, 22 improved > 5^ο (23.2%) and 11 progressed (11.5%). In-brace correction (IBC) was 49.7% for thoracic and 61.7% for lumbar curves. Analysis of progressed cases revealed that IBC (31.7% for thoracic and 34.4% for lumbar curves) and compliance (81.8% C for brace, 63.6% C for PSSE) was lower than average. Group A for treatment compliance (65.3%), showed significantly better results (70.9% stable, 29.1% improved, 0% progressed).

CONCLUSION

A combination of bracing and PSSE can effectively treat AIS, according to SRS inclusion criteria. 88.5% of patients avoided progression > 5^ο and only 6.4% overpassed 40^ο. IBC and compliance are the most important prognostic factors for successful treatment result. Early detection of AIS is also necessary for increased possibilities of effective conservative treatment.

The Impact of Training Time on Understanding the Treatment of Adolescent Idiopathic Scoliosis According to SOSORT International Guidelines: An Online Survey Study

The lack of knowledge by health professionals in the management of scoliosis can lead to an erroneous diagnosis. The aim of the current study was to understand the influence of length of professional experience on the knowledge of Brazilian physical therapists regarding international guidelines for the treatment of adolescent idiopathic scoliosis. The study was conducted using an online questionnaire consisting of 23 questions, divided into 8 questions on sociodemographic data and 15 questions based on information provided by the guidelines in the SOSORT 2016. In total, 506 physiotherapists were interviewed, and they comprised the study sample. The results showed that professionals who have been working for more than 6 years in the field have greater knowledge of AIS, seek to become more professional, and with that, have an understanding of AIS that is more aligned with the SOSORT. Length of experience made a difference when considering knowledge of the treatment of idiopathic scoliosis. The present study showed that a time since graduation of 6 years or more was satisfactory.

The efficacy of trunk bracing with an instrumented corrective exercise on spinal deformity, pulmonary function, trunk muscle endurance and quality of life in adolescent idiopathic scoliosis: Protocol for a parallel-groups clinical study (Preprint)

BACKGROUND

Adolescent idiopathic scoliosis is a 3D spine distortion with an unidentified etiology. It results in noticeable trunk deformity, decreased muscle strength and endurance at the trunk, changes in chest volume, breathing issues, and ultimately a decline in the quality of life. Trunk bracing and corrective exercises make up most of the treatment of patients with scoliosis when their deformity is between 20° and 45°, and they have not yet attained skeletal maturity. Evidence suggests that spinal deformity in people with scoliosis may result from improper motor control. Automatic response training is an exercise therapy technique that can modify the pattern of trunk muscle control for supporting the spinal column in normal alignment. An apparatus called a cantilever device is required for this type of exercise, which facilitates training at home. In spite of research showing the benefit of braces and therapeutic exercise in adolescents with scoliosis, less emphasis has been given to the impact of home-based training, especially when this intervention is paired with braces.

OBJECTIVE

We aim to compare the efficacy of bracing and a conventional exercise program to a combination treatment that includes trunk bracing and exercises with a cantilever device performed at home on the degree of spine curvature, pulmonary function, trunk muscular endurance, and quality of life.

METHODS

This study was a 2-arms parallel-group clinical study. A total of 16 adolescents with idiopathic scoliosis and single lumbar and thoracolumbar curves of 20°-45° were recruited and randomly assigned into 2 groups. Group A received a combination of trunk bracing and exercise using an instrument known as a "cantilever." Group B (controls) received trunk bracing and a conventional exercise program (without a tool). The study outcomes were the Cobb angle of the scoliotic curve, pulmonary function, the endurance of the trunk muscles, and quality of life. The study outcomes were measured at 2 time points: before the intervention (T1) and 12 weeks following the start of the intervention (T2; at this time, the intervention period has been completed). Multivariate analysis of variance was used to test between- and within-group differences.

RESULTS

Recruitment for this study began in fall 2022 and is expected to be completed by the end of summer 2023.

CONCLUSIONS

We studied the efficacy of a combined trunk bracing program and postural response exercises using a cantilever device in treating adolescent idiopathic scoliosis and compared it with trunk bracing and conventional home exercises. Exercises performed at home using a cantilever device are anticipated to raise the endurance of trunk muscles, which will help reduce trunk deformity, enhance pulmonary function, and improve the quality of life of participants.

Level of knowledge on conservative management of adolescent idiopathic scoliosis among undergraduate students in healthcare: A scoping review

BACKGROUND

Adolescent Idiopathic Scoliosis (AIS) is a three-dimensional deformity of the spine associated with pain and aesthetic changes. Various health care professionals may be led to evaluate and/or manage adolescents presenting AIS. There is no compiling of the studies evaluating the level of knowledge on AIS conservative management among undergraduate students in healthcare.

OBJECTIVE

To identify and map the current studies evaluating the level of knowledge of health profession students on AIS conservative management.

DESIGN

Scoping review.

METHODS

The search strategy was conducted in Scopus database. Three concepts were included: "Adolescent idiopathic scoliosis", "Knowledge" and "Undergraduate students studying in a healthcare field". Studies identification included (1) duplicates removing, (2) title and abstract screening, and (3) full-text screening. The quality of the included studies was assessed. Studies' characteristics were extracted, and results were summarized.

RESULTS

Searches yielded the identification of 245 citations. After duplicates removal and abstract screening, three full-text articles were identified. Following full-text review, two full-text articles were finally included. Both studies evaluated students in physiotherapy, but using distinct questionnaires. Both studies reported an unsatisfactory level of knowledge.

CONCLUSION

Knowledge of future health professionals about the conservative management of AIS has been barely evaluated. Therefore, no conclusion can be drawn regarding the level of knowledge of undergraduate health professions' students on AIS conservative management. The development a standardized questionnaire to adequately assess this knowledge across institutions and professions is required.

The preliminary results of physiotherapy scoliosis-specific exercises on spine joint position sense in adolescent idiopathic scoliosis: A randomized controlled trial

BACKGROUND

It has been observed that there are difficulties in maintaining spinal harmony in the absence of proprioceptive information, which has an important role in achieving postural control in scoliosis. One of the tests used to evaluate proprioceptive mechanisms is joint position reproduction.

OBJECTIVES

The main aim of our study was to investigate the effect of physiotherapy scoliosis-specific exercise (PSSE) on spine joint reposition (JR) sense. The second aim was to determine the effects of PSSE on the angle of trunk rotation (ATR), posture, and deformity perception in adolescent idiopathic scoliosis.

METHODS

Twenty-nine patients with adolescent idiopathic scoliosis (mean age 13.79 ± 1.82 years) were randomly allocated to two groups. "Schroth" exercises were applied to the PSSE group for 8 weeks (16 sessions). The control group was placed on the waiting list. Patients' JR error (dual inclinometer), ATR (scoliometer), posture parameters (PostureScreen Mobile, Posterior Trunk Asymmetry Index, and Anterior Trunk Asymmetry Index), and deformity perception (Walter Reed Visual Assessment Scale [WRVAS]) were assessed at the first session and at the end of 8 weeks.

RESULTS

The initial demographic characteristics, Cobb (thoracal: 19.41 ± 7.03 degrees; lumbar: 20.76 ± 7.24 degrees) and ATR (thoracal: 5.86 ± 3.98 degrees; lumbar: 5.66 ± 3.33 degrees) and clinical test parameters of the groups (JR, posture parameters, and WRVAS) were similar (P > .05). According to the findings, thoracal and lumbar JR error values (P < .05), ATR (P ≤ .001), posture parameters (P ≤ .001), and WRVAS (P = .048) were significantly improved in the PSSE group. Besides, when the groups were compared, a significant difference was found in favor of PSSE except for the deformity perception (P < .05).

CONCLUSIONS

Schroth exercises have a positive contribution for improving JR sense of the spine, vertebral rotation, and posture.

Effect of a 16-Week Yoga Program on Cobb’s Angle in Female Patients with Scoliosis

BACKGROUND Long-term postural imbalances can promote the development of diseases such as scoliosis or pain in the neck, shoulders, arms, and lumbar spine. Yoga combines exercises that target muscular strength and flexibility, suggesting that it can aid in attenuating structural and postural imbalances without the need for invasive procedures. The present study aimed to investigate the effect of a 16-week yoga program on Cobb’s angle and other postural indicators in patients with scoliosis.METHODS Ten middle-aged women living in South Korea who were judged to have scoliosis based on the results of posture tests participated in a 16-week yoga program.It consisted of two 70-min sessions per week during weeks 1–4, two 80-min sessions per week during weeks 5–9, and two 90-min sessions per week during weeks 10–16. The heights of the ilium and ischium were measured to check for pelvic imbalances. Shoulder height and Cobb’s angle in the spine were also assessed on radiography both before and after the intervention.RESULTS Following the 16-week program, Cobb’s angle had significantly decreased from 10.50±4.26 to 7.05±3.37 (p<0.001). However, there were no statistically significant differences between pre- and postintervention shoulder height (pre: 2.85±1.76 mm; post: 1.58±0.99 mm;p=0.124). In contrast, iliac height had decreased from 2.62±1.33 mm to 1.78±0.80 mm (p=0.048), and ischial height had decreased from 1.72±0.92 mm to 1.17±0.80 mm (p=0.043), and both differences were significant.CONCLUSIONS These results suggest that regular participation in yoga is effective for maintaining or improving postural indicatorsand attenuating imbalances in middle-aged women with scoliosis.

Physiotherapeutic Scoliosis-Specific Exercise Methodologies Used for Conservative Treatment of Adolescent Idiopathic Scoliosis, and Their Effectiveness: An Extended Literature Review of Current Research and Practice

Due to the multifactorial etiology of scoliosis, a comprehensive treatment plan is essential for conservative management. Physiotherapeutic scoliosis-specific exercise (PSSE) methods have lately gained popularity for the conservative treatment of scoliosis. The aim of this study was to analyze the PSSE methodologies used for conservative treatment of adolescent idiopathic scoliosis (AIS), as well as their effectiveness. The study was based on an extended literature search conducted in the PubMed, Google Scholar, PEDro, eLABA, and BioMed Central databases. A total of 123 articles were selected for this study (including articles overviewed in systematic reviews and meta-analyses) after applying the inclusion criteria. The study revealed that inappropriate management of AIS could result in serious health problems. Conservative interventions that aid in stabilizing spine curvature and improving esthetics are preferred for scoliosis treatment. Bracing has traditionally been the mainstay of treatment, but growing evidence suggests that PSSE physiotherapy allows effective management of idiopathic adolescent scoliosis. Currently, there are the following PSSE physiotherapy schools in Europe: Schroth, SEAS, BSPTS, FED, FITS, Lyon, Side Shift, and DoboMed. The methodologies of these schools are similar, in that they focus on applying corrective exercises in three planes, developing stability and balance, breathing exercises, and posture awareness. Although high-quality research supporting the effectiveness of PSSE physiotherapy in the treatment of AIS is lacking, existing evidence indicates that PSSE physiotherapy helps to stabilize spinal deformity and improve patients’ quality of life. Among the abovementioned methodologies, Schroth is the most widely studied and has been proven to be effective. However, both SEAS and BSPTS effectively stabilize and even reduce the Cobb angle of scoliosis. Data supporting the validity of other methodologies are very limited. Only the Schroth method significantly reduces the angle of trunk rotation, while both SEAS and Schroth methods greatly improve the quality of life indicators. In any case, the available evidence is insufficient to confirm the advantage of one specific physiotherapy technique over others.

The Hereditary Nature of Adolescent Spinal Deformities: A Study of Over 600,000 Adolescents

STUDY DESIGN

A cross-sectional study.

OBJECTIVE

We designed this study to investigate the risk for spinal deformity among individuals whose parents had a spinal deformity.

SUMMARY OF BACKGROUND DATA

Adolescent idiopathic scoliosis and Scheuermann kyphosis (SK) are common adolescent spinal deformities (ASD) with a significant impact on public health. Timely treatment with bracing is effective in halting or slowing the progression of these deformities. However, screening healthy adolescents for spinal deformities remains debatable. While the leading medical organizations endorse contradictory positions regarding the screening of the general population, there is a consensus that screening of targeted population should be considered. Due to their genetic predisposition, adolescents whose parents suffer from a spinal deformity may be candidates for targeted screening.

METHODS

We conducted a nationwide, population-based study of 611,689 Israeli adolescents, aged 16 to 19 years old, who were screened for spinal deformities between the years 2000 and 2019. The data for this study were derived from a central database containing medical records of all adolescents who were examined preliminary to mandatory military service. In our study, ASD were strictly defined by plain x-ray.

RESULTS

Compared with adolescents of whose parents did not have a spinal deformity, the odds ratios (OR) for ASD among adolescents whose father, mother, or both parents had spinal deformity were 1.46, 1.74, and 2.58, respectively. These ratios were consistent in multivariate models.

CONCLUSION

We have found a considerable increased risk for adolescent spinal deformities among adolescents whose parents suffered from spinal deformities. We believe that our findings should serve the leading medical organizations when considering the screening of targeted populations.

Short-Term Outcomes of the Boston Brace 3D Program Based on SRS and SOSORT Criteria: A Retrospective Study

Background: Adolescent idiopathic scoliosis (AIS) is characterized by a lateral curvature of the spine with a Cobb angle greater than 10 degrees, accompanied by rotation of the vertebral body. Bracing has been shown to be effective in halting the progression of at-risk curves, and, in some cases, even improving the Cobb angle by 6° or more. The Boston Brace 3D is part of the Boston Orthotics and Prosthetics standardized scoliosis program. The orthosis is custom-fabricated from scans, computer-aided design (CAD), and computer-aided manufactured (CAM) thoracolumbosacral orthosis used in the non-operative management of AIS. Aim: To evaluate the outcomes of a scoliosis program utilizing the Boston Brace 3D orthosis for patients with AIS, based on SRS and SOSORT criteria. Design: Retrospective study. Methods: An electronic medical records search was conducted to identify first-time brace wearers fitted between 1 January 2018, and 30 June 2019, at Boston Orthotics and Prosthetics Boston area clinics that met the SRS/SOSORT research guidelines. The initial out-of-brace, in-brace, and last follow-up X-rays (taken at least 12 months after fitting) were compared. Results: 84% of patients presenting with a single curve and 69% of patients with a double curve saw their curves improve (reduced 6° or more) or remain unchanged (±5°). Thirty-one patients started with a single curve between 25° and 30°, and thirty-two presented at 30° or below. Fifty-nine patients started with a double curve between 25° and 30°, and 59 patients presented at 30° or below. In general, the patients who wore their brace for more hours per day saw improved results. Conclusion: The Boston Brace 3D program is effective in controlling (and in some cases improving) curve progression in the non-operative management of adolescent idiopathic scoliosis. The approach is a repeatable system, as shown in this cohort of thirteen clinicians across six area clinics following the Boston Brace 3D clinical guidelines.
