Abstract
PURPOSE Adolescent idiopathic scoliosis (AIS) is a common pediatric spinal deformity frequently treated with patient scoliosis-specific exercises (PSSE). The purpose of this study is to perform a systematic review and meta-analysis of randomized controlled trials and sensitivity analysis of observational studies to determine the impact of PSSE on outcomes for AIS. METHODS A systematic review and meta-analysis on impact of PSSE for patients with AIS was performed. Databases used included PubMed, CINAHL, MEDLINE, Cochrane, and ScienceDirect database inception to October 2022. Inclusion criteria included use of PSSE, patient population of AIS, and full text. RESULTS A total of 26 articles out of 628 initial retrieved met final inclusion criteria (10 randomized controlled trials (RCTs), 16 observational studies). Total included patients (n = 2083) had a frequency weighted mean age of 13.2 ± 0.9 years and a frequency weighted mean follow-up of 14.5 ± 20.0 months. Based on only data from RCTs with direct comparison groups (n = 7 articles), there was a statistically significant but clinically insignificant improvement in Cobb angle of 2.5 degrees in the PSSE group (n = 152) as compared to the control group (n = 148; p = 0.017). There was no statistically significant improvement in Cobb angle when stratified by small curve (< 30 degrees) or large curve (> 30 degrees) with PSSE (p = 0.140 and p = 0.142, respectively). There was no statistically significant improvement in ATR (p = 0.326) or SRS-22 score (p = 0.370). CONCLUSION PSSE may not provide any clinically significant improvements in Cobb angle, ATR, or SRS-22 scores in patients with AIS. PSSE did not significantly improve Cobb angle when stratified by curve size. LEVEL OF EVIDENCE Level I.

Abstract
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.

Abstract
(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.

Abstract
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.

Abstract
(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.

Abstract
The objective of this review was to offer new information on the effectiveness of Schroth method on postural control and balance in patients with adolescent idiopathic scoliosis (AIS). PubMed, EBSCO, and Google Scholar databases were searched from June 2022 to August 2022 for prospective controlled trials and randomized controlled trials related to effects of Schroth exercises on postural control and balance in patients with AIS. The key words AIS, Schroth, balance, postural control, and proprioception were used. Studies written in English language, in the last decade were included. Seven studies were included in the review, with a total of 244 study subjects. Three studies investigated the effectiveness of Schroth exercises on balance and postural control. Two studies included investigated the effectiveness of Schroth method in combination with additional treatments of bracing and hippotherapy, while two other studies investigated effectiveness of Schroth when compared with Pilates and proprioceptive neuromuscular facilitation (PNF). The treatment duration varied from a week to 6 months. From the findings of this review, it is supported that Schroth method can have positive effects on balance and postural control in AIS patients. Further investigation is necessary.

Abstract
Background: This study investigated the therapeutic effects of 12-week Schroth rehabilitation exercises (SRE) in improving Cobb’s angle, scoliometer readings, lumbar lordosis, and the calcaneal valgus angle of patients with idiopathic scoliosis. Methods: This pilot study included 60 adolescent patients diagnosed with idiopathic scoliosis by a rehabilitation physician based on a Cobb’s angle of ≥10° using total anteroposterior plain radiography. Patients were classified into groups with a Cobb’s angle of 10–19° (G1), 20–29° (G2), and ≥30° (G3). Cobb’s angle, scoliometer readings, lumbar lordosis, and calcaneal valgus angles were analyzed before and after the 12-week SRE. Results: SRE improved Cobb’s angle (−6.85), scoliometer readings (−2.80), lumbar lordosis (4.23), and calcaneal valgus angles (left, −3.76; right, −2.83) regardless of the initial scoliosis angle, and within-group changes were significant (p < 0.001). In this study, participants in all three groups had undergone SRE, regardless of initial scoliosis severity, and the findings were significant. Conclusion: SRE can be used for patients with idiopathic scoliosis to improve asymmetric musculoskeletal morphology and the patient’s quality of life.

Abstract
Background Physiotherapeutic scoliosis-specific exercise (PSSE) has proven to be an important treatment for patients with adolescent idiopathic scoliosis. However, there is a lack of understanding of the role of PSSE in older adults with spinal deformity. Methods An electronic, 14-question survey with questions regarding the use of physical therapy (PT) and PSSE for adult spinal deformity was administered to all Scoliosis Research Society members. Physician location, age, specialty, years in experience, and management preferences were quantified using descriptive analyses. Results Of the 98 surgeons who participated in this study, the majority of respondents were from North America (71.1%), and the mean age was 51.87 ± 10.93 years; approximately 98% of respondents were orthopedic surgeons, and 48.0% had been in practice for more than 21 years. Sixty-four percent reported they prescribed PT in their practice, with 52% of respondents often using PT as nonoperative treatment; 21.4%, preoperative; and 40.8% postoperative. The primary reason for PT referral was persistent pain (40.3%), followed by impairments to the patient's balance or gait (34.3%) and difficulty with daily living activities (25.4%). The primary indications for not referring postoperative patients to PT were lack of perceived value from PT (50%), lack of evidence supporting the benefits from PT (31.3%), and a lack of physical therapists appropriately trained for scoliosis (18.8%). Of the respondents, 74% were familiar with PSSE and 66% were comfortable prescribing PSSE postoperatively. In addition, 28% of respondents agreed that >12 weeks postoperation was the ideal time for PSSE referral, followed by 6 to 8 weeks postoperation (26.2%) and immediately postoperation (18%). Conclusions The results show that the majority of respondents prescribed PSSE solely for nonoperative treatment. Respondents who did not prescribe PSSE reported skepticism due to a lack of perceived value. This suggests the need for further research into the benefits of PSSE. Level of Evidence 5. Clinical Relevance Physiotherapeutic Scoliosis Specific Exercises (PSSE) is an important non-operative treatment for patients with Adolescent Idiopathic Scoliosis (AIS) but is understudied in Adult Spinal Deformity (ASD) patients, suggesting further clinical research. This study demonstrates that only two-thirds of the respondents familiar with PSSE were comfortable prescribing PSSE postoperatively suggesting the need for further research into the effectiveness and benefits of PSSE in ASD patients.

Abstract
Background The Cobb angle is proposed as the “disease process” outcome for scoliosis research because therapies aim to correct or stop curve progression. While the Scoliosis Research Society recommends the Cobb angle as the primary outcome, the Society on Scoliosis Orthopaedic and Rehabilitation Treatment prioritises, as a general goal, patient related outcomes over Cobb angle progression. Objective To determine the threshold of change in the Cobb angle in adolescents with idiopathic scoliosis (AIS) who perceive improvement in a 6-months randomized controlled trial comparing a Schroth exercise intervention added to the standard of care to the standard of care alone. Methods This is a secondary analysis of data from a randomized controlled trial of 50 patients with AIS, with curves ranging from 10° to 45°, with or without a brace. Participants with diagnoses other than AIS, surgical candidates or patients who had scoliosis surgery were excluded. The 6-month interventions consisted of Schroth exercises added to standard-of-care (observation or bracing) with daily home exercises and weekly therapy sessions (Schroth) or standard-of-care alone (Control). The anchor method for estimating the minimal important difference (MID) in the largest Cobb angles (LC) was used. Patient-reported change in back status over the 6-month treatment period was measured using the Global Rating of Change (GRC) scale as anchor varying from − 7 (“great deal worse”) to + 7 (“great deal better”). Participants were divided into two groups based on GRC scores: Improved (GRC ≥2) or Stable/Not Improved (GRC ≤1). MID was defined as the change in the LC that most accurately predicted the GRC classification as per the receiver operating characteristic curve (ROC). Results The average age was 13.4 ± 1.6 years and the average LC was 28.5 ± 8.8 °s. The average GRC in the control group was − 0.1 ± 1.6, compared to + 4.4 ± 2.2 in the Schroth group. The correlation between LC and GRC was adequate (r = − 0.34, p < 0.05). The MID for the LC was 1.0 °. The area under the ROC was 0.69 (0.52–0.86), suggesting a 70% chance to properly classify a patient as perceiving No Improvement/Stable or Improvement based on the change in the LC. Conclusion Patients undergoing Schroth treatment perceived improved status of their backs even if the Cobb angle did not improve beyond the conventionally accepted threshold of 5°. Standard of care aims to slow/stop progression while Schroth exercises aim to improve postural balance, signs and symptoms of scoliosis. Given the very small MID, perceived improvement in back status is likely due to something other than the Cobb angle. This study warrants investigating alternatives to the Cobb angle that might be more relevant to patients. Trial registration ClinicalTrials.gov, NCT01610908.

Abstract
The treatment of scoliosis has a long history dating back to Hippocrates and his luxation table. In recent history, conservative rehabilitation treatment methods have come and gone. Some have had more longevity than others and currently there are only a handful of these “schools” for rehabilitation in existence. What is important to note in this twenty-first century world is that any approach to bracing or scoliosis rehabilitation must strive for a correction effect and be as user-friendly as possible. Patients look to achieve some measure of success, whether it be halted Cobb angle, improved breathing function, decreased rotation, or postural improvement via trunk symmetry. Katharina Schroth created her method in 1921 as a result of self-analysis of her own imperfect scoliotic torso and the effect on it as she altered her breathing patterns. It was from these observations and self-experimentation that she devised her rotational angular breathing method. Subsequently, the Schroth method evolved under the leadership of her daughter, Christa Lehnert-Schroth P.T., and grandson, Dr. Hans-Rudolf Weiss. Collaboration with Dr. Jacques Chêneau led to a new Schroth method compatible scoliosis bracing approach. The most recent advancement of Chêneau bracing is the Gensingen Brace® (GBW). Gensingen braces have an asymmetric design and rely on Schroth principles of correction in a smaller, lighter, more wearer-friendly brace. Each brace is designed to be a complementary supportive orthosis. It may be used independently, or in conjunction with Schroth exercise protocols.

Abstract
Background Recent randomized controlled trials (RCTs) support using physiotherapeutic scoliosis-specific exercises (PSSE) for adolescents with idiopathic scoliosis (AIS). All RCTs reported statistically significant results favouring PSSE but none reported on clinical significance. The number needed to treat (NNT) helps determine if RCT results are clinically meaningful. The NNT is the number of patients that need to be treated to prevent one bad outcome in a given period. A low NNT suggests that a therapy has positive outcomes in most patients offered the therapy. The objective was to determine how many patients require Schroth PSSE added to standard care (observation or brace treatment) to prevent one progression (NNT) of the Largest Curve (LC) or Sum of Curves (SOC) beyond 5° and 10°, respectively over a 6-month interval. Methods This was a secondary analysis of a RCT. Fifty consecutive participants from a scoliosis clinic were randomized to the Schroth PSSE + standard of care group (n = 25) or the standard of care group (n = 25). We included males and females with AIS, age 10–18 years, all curve types, with curves 10°- 45°, with or without brace, and all maturity levels. We excluded patients awaiting surgery, having had surgery, having completed brace treatment and with other scoliosis diagnoses. The local ethics review board approved the study (Pro00011552). The Schroth intervention consisted of weekly 1-h supervised Schroth PSSE sessions and a daily home program delivered over six months in addition to the standard of care. A prescription algorithm was used to determine which exercises patients were to perform. Controls received only standard of care. Cobb angles were measured using a semi-automatic system from posterior-anterior standing radiographs at baseline and 6 months. We calculated absolute risk reduction (ARR) and relative risk reduction (RRR). The NTT was calculated as: NNT = 1/ARR. Patients with missing values (PSSE group; n = 2 and controls; n = 4) were assumed to have had curve progression (worst case scenario). The RRR is calculated as RRR = ARR/CER Results For LC, NNT = 3.6 (95% CI 2.0–28.2), and for SOC, NNT = 3.1 (95% CI 1.9–14.2). The corresponding ARR was 28% for LC and 32% for the SOC. The RRR was 70% for LC and 73% for the SOC. Patients with complete follow-up attended 85% of prescribed visits and completed 82.5% of the home program. Assuming zero compliance after dropout, 76% of visits were attended and 73% of the prescribed home exercises were completed. Conclusions The short term of Schroth PSSE intervention added to standard care provided a large benefit as compared to standard care alone. Four (LC and SOC) patients require treatment for the additional benefit of a 6-month long Schroth intervention to be observed beyond the standard of care in at least one patient.

Abstract
BACKGROUND Bracing has been shown to decrease significantly the progression of high-risk curves to the threshold for surgery in patients with adolescent idiopathic scoliosis (AIS), but the treatment failure rate remains high. There is evidence to suggest that Schroth scoliosis-specific exercises can slow progression in mild scoliosis. The aim of this study was to evaluate the efficacy of Schroth exercises in AIS patients with high-risk curves during bracing. METHODS A prospective, historical cohort-matched study was carried out. Patients diagnosed with AIS who fulfilled the Scoliosis Research Society (SRS) criteria for bracing were recruited to receive Schroth exercises during bracing. An outpatient-based Schroth program was given. Data for these patients were compared with a 1:1 matched historical control group who were treated with bracing alone. The assessor and statistician were blinded. Radiographic progression, truncal shift, and SRS-22r scores were compared between cases and controls. RESULTS Twenty-four patients (5 males and 19 females, mean age 12.3 ± 1.4 years) were included in the exercise group, and 24 patients (mean age 11.8 ± 1.1 years) were matched in the control group. The mean follow-up period for the exercise group was 18.1 ± 6.2 months. In the exercise group, spinal deformity improved in 17% of patients (Cobb angle improvement of ≥ 6°), worsened in 21% (Cobb angle increases of ≥ 6°), and remained stable in 62%. In the control group, 4% improved, 50% worsened, and 46% remained stable. In the subgroup analysis, 31% of patients who were compliant (13 cases) improved, 69% remained static, and none had worsened, while in the non-compliant group (11 cases), none had improved, 46% worsened, and 46% remained stable. Analysis of the secondary outcomes showed improvement of the truncal shift, angle of trunk rotation, the SRS function domain, and total scores in favor of the exercise group. CONCLUSION This is the first study to investigate the effects of Schroth exercises on AIS patients during bracing. Our findings from this preliminary study showed that Schroth exercise during bracing was superior to bracing alone in improving Cobb angles, trunk rotation, and QOL scores. Furthermore, those who were compliant with the exercise program had a higher rate of Cobb angle improvement. The results of this study form the basis for a randomized controlled trial to evaluate the effect of Schroth exercises during bracing in AIS. TRIAL REGISTRATION HKUCTR-2226.

Abstract
OBJECTIVE The objective is the description and summary of the current state of idiopathic scoliosis treatment with physical therapy based on new scientific knowledge and concluded from more than 15 years of experience as a leading physician in two well-known clinics specializing in the conservative treatment of scoliosis. MATERIALS AND METHODS Based on current scientific publications on physical therapy in scoliosis treatment and resulting from the considerable personal experience gained working with conservative treatment and consulting scoliosis patients (as inpatients and outpatients), the current methods of physical therapy have been compared and evaluated. RESULTS Physical therapy according to Schroth and Vojta therapy are at present the most common and effective methods in the physical treatment of idiopathic scoliosis. These methods can be applied during inpatient or outpatient treatment or intensified in the practice of specialized therapists. DISCUSSION As there are only a few scientific studies on this subject, the author's findings are based mainly on his own experiences of the conservative treatment of idiopathic scoliosis. Athough these experiences are the results of over 15 years of working in the field of therapy, and the Schroth method in combination with corrective bracing presents highly promising results, it would nevertheless be desirable to conduct detailed scientific studies to verify the effectiveness of conservative treatment.
