An Innovative Method for the Conservative Treatment of Idiopathic Scoliosis Using the GraviSpine Device According to the Concept of Spinal Reflex Balance

Objectives: Conservative treatment of idiopathic scoliosis is more effective as a result of early diagnosis in conjunction with the use of specific physiotherapy and bracing techniques. Our aim was to investigate the effectiveness of specific physiotherapy developed according to the concept of spinal reflex balance using the GraviSpine device. This study is a retrospective analysis of prospectively collected data. Methods: A total of 199 patients aged 6-17 years, with a mean age of 11.26 ± 3.35 years, including 168 girls (84.4%) and 31 boys (15.6%), out of a total of 830 patients treated for IS at the Scoliosis Treatment Center in 2014-2019 were included in the assessment, which was conducted according to the inclusion and exclusion criteria. The study group was divided into three age groups. Group A subjects were 6-9 years old; group B, 10-12 years old; and group C, 13-17 years old. The mean follow-up time was 28.71 ± 10.98 months. Treatment outcomes were compared, based on changes in the Cobb angle and the angle of trunk rotation before and after treatment, both within the groups and with respect to sex and curvature location, using the Wilcoxon signed-rank test. Cobb angle changes in patients were classified as improvements, stabilizations, or deteriorations according to the SOSORT criteria. Results: A majority of patients improved or stabilized after treatment, with 67%, 71%, and 90% of subjects in groups A, B, and C, respectively, achieving these results. In group C (the oldest children), a statistically significant reduction of -1.84° ± 6.88° (6.31%) in the mean Cobb angle was achieved after treatment. With regard to sex, improvements and stabilizations accounted for 81% of cases in girls and 61% in boys, respectively. With respect to location, statistically significant reductions in the Cobb angle were noted for thoracic and thoracolumbar spines of -2.2° ± 7.54° (10.17%) p = 0.022 and -2.2° ± 6.58° (6.36%) p = 0.049, respectively. A significant reduction in the mean angle of trunk rotation was obtained in the group and in three curvature locations. Conclusions: Based on the presented research findings, the utilization of the GraviSpine device as an adjunct to specific PSSE (physiotherapeutic scoliosis-specific exercises) physiotherapy and bracing in the management of pediatric patients with mild to moderate scoliosis appears to enhance treatment efficacy.

DEEP LEARNING FOR ANALYSIS OF CHANGES IN VITAL CAPACITY AND BLOOD MARKERS AFTER SWIMMING MATCHES BASED ON BLENDED LEARNING

ABSTRACT Introduction Nowadays, more people are concerned with physical exercise and swimming competitions, as a major sporting event, have become a focus of attention. Such competitions require special attention to their athletes and the use of computational algorithms assists in this task. Objective To design and validate an algorithm to evaluate changes in vital capacity and blood markers of athletes after swimming matches based on combined learning. Methods The data integration algorithm was used to analyze changes in vital capacity and blood acid after combined learning swimming competition, followed by the construction of an information system model to calculate and process this algorithm. Results Comparative experiments show that the neural network algorithm can reduce the calculation time from the original initial time. In the latest tests carried out in about 10 seconds, this has greatly reduced the total calculation time. Conclusion According to the model requirements of the designed algorithm, practical help has been demonstrated by building a computational model. The algorithm can be optimized and selected according to the calculation model according to the reality of the application.

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.

Does exercise therapy improve pulmonary function in patients with Adolescent Idiopathic Scoliosis?

INTRODUCTION

Exercise therapy is frequently used for treating patients with Adolescent Idiopathic Scoliosis (AIS) however no previous review has evaluated the effect of exercise therapy on pulmonary function in this population.

OBJECTIVE

To systematically analyze the literature on the effect of exercise therapy on pulmonary function in patients with AIS.

METHODS

A systematic electronic database search (CINAHL, Embase, Medline, Web of Science) was conducted. Manual searches of key reviews and studies were also conducted. Studies that included exercise-based interventions to improve pulmonary function in patients with AIS and reported pre- and post-intervention pulmonary function test scores were included. Test scores were compared using standardized mean difference (SMD) between intervention and control groups in randomized control trials (RCT) and mean ± SD between pre- and post-intervention in prospective intervention studies (PI). Methodological quality was assessed using a modified Downs and Black checklist.

RESULTS

Fifteen studies met the inclusion criteria (six RCTs and nine PIs). Results indicated the positive effect of exercise-based therapy on lung volumes (FVC/VC) and FEV₁ in patients with AIS.

CONCLUSION

Exercise therapy has a positive effect on lung volumes in patients with AIS. The quality of many studies was only 'fair,' therefore more suitably powered higher level clinical trials are required.

Locoregional lung ventilation distribution in girls with adolescent idiopathic scoliosis and healthy adolescents. The immediate effect of Schroth 'derotational breathing' exercise in a controlled-trial

BACKGROUND

Scoliosis curves present transverse plane deviations due to vertebral rotation. The Schroth method supports thoracic derotation by training patients to exert "derotational" breathing based on assumed enhanced ventilation in areas called "humps" in scoliosis and a patient's ability to voluntarily direct ventilation in less ventilated areas called "flats."

OBJECTIVE

To assess the asymmetric ventilation distribution and the ability of patients to direct their ventilation to perform derotational breathing.

METHODS

Twelve girls with adolescent idiopathic scoliosis and 12 healthy girls performed 3 × 3 min of rest, maximal, and derotational breathing. Electrical impedance tomography was used to record locoregional lung ventilation distribution (LLVD) within 4 thoracic regions of interest: anterior right (ROI 1), anterior left (ROI 2), posterior right (ROI 3), and posterior left (ROI 4) quadrants. Humps and flats were the sums of ROI '2 + 3' and ROI '1 + 4,' respectively.

RESULTS

Overall, no difference in LLVD was observed in the flats and humps between groups. At rest, the LLVD in the humps was more elevated than that in the flats (51.5 ± 8.1% versus 43.6 ± 7.9%; p = .021) when considering both groups. Maximal and derotational breathing led to a more homogeneous LLVD between the humps and flats.

CONCLUSION

The postulated derotational breathing effect was not confirmed.

The Type of Conservative Management Could Be Related to the Strength of the Inspiratory Muscles of Adolescents with Idiopathic Scoliosis—A Case Series

Adolescent idiopathic scoliosis (AIS) is a lateral curvature of the spine with a Cobb angle of at least 10° with an unknown etiology. It is recognized that AIS may affect respiratory function. This study aims to describe and compare respiratory function in a case series of patients with scoliosis who underwent different types of therapeutic management: no intervention, orthotic brace, and global postural reeducation (GPR). Fifteen AIS patients were included in this study (seven no intervention, four orthotic brace and four GPR). Lung function and inspiratory muscle strength were measured and analyzed, as well as sociodemographic, clinical, and anthropometric variables. Significant correlations were observed between height (cm) and maximum inspiratory pressure (MIP) reference (cmH2O) and forced vital capacity (FVC) (liters) (r = 0.650 and r = 0.673, respectively; p < 0.01); weight (Kg) and MIP reference (cmH2O) (r = 0.727; p < 0.01); and Main curve degrees (Cobb angle) and FVC% (r = −0.648; p < 0.01). The AIS cases that underwent GPR treatment presented a greater MIP (% predictive) compared to the no intervention and brace cases (201.1% versus 126.1% and 78.4%, respectively; p < 0.05). The results of this case series show a possible relation whereby patients undergoing treatment with the GPR method have greater inspiratory muscle strength compared to the no intervention and brace cases. Studies with larger samples and prospective designs must be performed to corroborate these results.

Effects of a Personalized Exercise Rehabilitation Device on Dynamic Postural Balance for Scoliotic Patients: A Feasibility Study

Scoliosis, which is defined as a 3-dimensional spine deformity, may be caused by new-onset degenerative changes that occur well after skeletal maturity and exhibit an asymmetrical postural balance pattern more common to adult deformity than adolescent scoliosis. The aim of this study was to verify whether an exercise program using a personalized exercise rehabilitation device can influence the dynamic postural balance of scoliotic patients. The personalized exercise rehabilitation device was designed to increase the efficacy of 3D postural correction for different curve patterns. 20 subjects were instructed to perform the personalized exercise program that consists of axial elongation, derotation, deflexion, facilitation and stabilization. The results of this study showed that the differences in clinical variables associated with imbalanced posture between the convex and concave side decreased after performing the personalized exercise. Consequentially, a well-designed and manufactured exercise rehabilitation device could be helpful for improving postural balance. Furthermore, the paper suggests that specific exercises using a personalized exercise rehabilitation device can provide the most appropriate exercise therapy and positively correct the asymmetrical postural balance patterns for scoliotic patients.

Standing in Schroth trained position significantly changes Cobb angle and leg length discrepancy: a pilot study

STUDY DESIGN

Retrospective.

OBJECTIVE

The aim of this study is to evaluate if standing in a Schroth trained position influences the radiographic assessment of Cobb angle and other radiographic parameters compared to a normal standing position. Schroth method has been associated with improved Cobb angle. This study aims to evaluate if standing in the Schroth trained position influences radiographic assessment of Cobb angle compared to a normal standing position.

METHODS

This is a retrospective review of patients with adolescent idiopathic scoliosis (AIS) who were participating in Schroth therapy at the time of radiographs. Ten pairs of radiographs were included in this study. Each pair consisted of two micro-dose biplanar PA thoracolumbar spine radiographs obtained on the same day, one with the patient standing in the Schroth trained position and one in their normal standing position. Each pair of radiographs was independently evaluated by three attending pediatric spine surgeons for Cobb angle, coronal balance, shoulder balance, and leg length discrepancy, for a total of 30 paired readings (3 readings for each of the 10 pairs of radiographs).

RESULTS

Major Cobb angle was a mean of 6° less (p = 0.02) and the compensatory curve was 5° less (p = 0.03) in the Schroth trained position compared to their normal standing position. Neither coronal balance (p = 0.40) nor shoulder balance (p = 0.16) was significantly different. Mean leg length discrepancy was 6.8 mm greater in the Schroth trained versus normal position (p < 0.001).

CONCLUSION

Standing in a Schroth trained position for a PA spine radiograph was associated with a mean change in major Cobb angle of 6° compared to a normal standing position. If bracing was recommended for curves > 25° and surgery for curves > 45°, different treatment recommendations would have been made in 33% (10/30) of attendings' readings for the Schroth versus normally paired radiographs taken on the same day on the same patient. Studies evaluating the effect of Schroth therapy on Cobb angle must report if patients are standing in a normal or Schroth trained position during radiographs for conclusions to be valid, or differences may be due to a temporary, voluntary change in posture.

Outcome of 24 Weeks of Combined Schroth and Pilates Exercises on Cobb Angle, Angle of Trunk Rotation, Chest Expansion, Flexibility and Quality of Life in Adolescents with Idiopathic Scoliosis

Background

This study aimed to quantify the outcomes of combining Schroth and Pilates exercises on the Cobb angle, angle of trunk rotation (ATR), chest expansion, flexibility (trunk flexion), and quality of life (QoL) in adolescents with mild and moderate idiopathic scoliosis.

Material/Methods

Sixty-nine adolescents with idiopathic scoliosis aged 10–17 years, presenting with a Cobb angle of 10–45º were enrolled in this study. The treatment protocol, including selected exercises from Schroth and Pilates methods, was performed over 24 weeks and consisted of 2 periods of 2-week treatment regimens performed daily for 60 minutes. Each of treatment periods was then followed by the same home program treatment for 10 weeks. Cobb angle (x-rays), ATR (Scoliometer), chest expansion (cm), trunk flexion (cm, distance between C7 to S2 with measuring tape), and QoL (SRS-22r Scoliosis Research Society Questionnaire) were assessed pre-treatment, at 12 week, and at 24 weeks.

Results

Significant improvements (P<0.05) were found in both groups of patients wearing and not wearing a brace for Cobb angle (from 21.97±4.99° to 18.11±6.39°; from 14.19±3.11° to 11.66±2.73°), angle of trunk rotation (from 7.19±1.36° to 5.36±1.66°; from 4.72±1.04° to 3.58±0.94°), chest expansion (from 2.56±0.84 cm to 3.46±0.72 cm; from 2.57±0.87 cm to 3.52±0.72 cm), trunk flexion (from 9.55±1.95 cm to 14.33±2.40 cm; from 9.82±2.61 cm to 13.98±2.18 cm) and QoL (from 3.50±0.27 to 3.82±0.2; from 3.42±0.24 to 3.78±0.23) respectively.

Conclusions

This study showed that combined exercises provided benefit on the Cobb angle, ATR, chest expansion, trunk flexion and QoL in adolescents with mild and moderate idiopathic scoliosis.

H-reflex changes in adolescents with idiopathic scoliosis: a randomized clinical trial

[Purpose] To detect H-reflex asymmetry and investigate the effect of direction sensitive exercise therapy protocol among patients with thoracolumbar and/or lumbar scoliosis. [Subjects and Methods] Fifty patients (10-17 years), Cobb's angle 10-20 degrees with thoracolumbar and lumbar scoliosis participated in the study. Soleus H-reflex was tested on both sides during prone lying position and standing position. Patients were randomly assigned into two groups. Group I received direction sensitive exercise therapy while the participants in group II received traditional exercise. Exercises were applied three times per week for twelve successive weeks. [Results] There were significant differences indicating asymmetry in the H-reflex amplitude on concave side. Cobb's angle significantly decreased and the H-reflex amplitude on concave side as well as H concave/convex ratios in both lying and standing significantly increased in both groups. Direction sensitive exercise therapy showed a more significant increase in the measured outcomes than traditional exercises therapy protocol. [Conclusion] H-reflex test was effective in discovering the asymmetry between concave and convex sides. Based on H-reflex test, direction-sensitive exercise therapy was more effective than traditional exercises in decreasing Cobb's angle and increasing H-reflex values as well as H/H percent in concave side in patients with adolescent idiopathic scoliosis.
