Loss of body height is observed in patients with idiopathic scoliosis (IS) due to spine curvatures. The study compared pulmonary parameters obtained from spirometry examination considering the measured versus the corrected body height. One hundred and twenty adolescents with Lenke type 1 or 3 IS who underwent preoperative spirometry examination and radiographic evaluation were enrolled. The mean thoracic Cobb angle was 68° ± 12.6, range 48–102°. The difference between the measured and the corrected body height increased with the greater Cobb angle. Using the corrected body height instead of the measured body height significantly changed the predicted values of pulmonary parameters and influenced the interpretation of the pulmonary testing results.

This study aimed to compare the Italian Spine Youth Quality of Life Questionnaire (ISYQOL-PL) versus the Scoliosis Research Society-22 (SRS-22) questionnaire scores evaluating the validity of the concurrent and known-groups. Eighty-one girls (mean age 13.5 ± 1.8 years) with idiopathic scoliosis (IS) with a mean Cobb angle of 31.0 (±10.0) degrees were examined, all treated with a corrective TLSO brace for an average duration of 2.6 (±1.9) years. The patients’ scores were compared as follows: (1) age: ≤13 years vs. &gt, 13 years), (2) scoliosis severity: mild (Cobb angle 10–30°) vs. moderate (Cobb angle &gt, 30°), (3) single curve pattern vs. double curve pattern. Lin’s concordance correlation coefficient was used to evaluate the strength of the association between ISYQOL-PL and SRS-22 scores. T-tests were applied to assess if the ISYQOL-PL measure and SRS-22 total score were significantly different in the different groups of patients. The concurrent validity analysis showed a moderate correlation (Lin pccc = 0.47). The ISYQOL-PL showed a significantly better quality of life in mild than moderate scoliosis. The severity of scoliosis but not the age or the curve pattern demonstrated a direct statistically significant effect on patients’ quality of life only when evaluated using the ISYQOL-PL.

Body posture develops during the growing period and can be documented using trunk photography. The study aims to evaluate the body posture in children aged 7–10 years undergoing a dedicated physical activities program versus regular school sport. A total of 400 children, randomly chosen from a cohort of 9300 participating in a local scoliosis screening program, were evaluated twice at a one-year interval. A total of 167 children were involved in regular school sport (control group), while 233 received both school sport and a dedicated physical activities program (intervention group). Standardized photographic habitual body posture examination was performed at enrollment (T0) and one-year after (T1). Sacral slope (SS), lumbar lordosis (LL), thoracic kyphosis (TK), chest inclination (CI), and head protraction (HP) were measured. At T0, the body posture parameters did not differ between groups. At T1 in the controls, all five parameters tended to deteriorate (insignificant): SS p = 0.758, LL p = 0.38, TK p = 0.328, CI p = 0.081, and HP p = 0.106. At T1 in the intervention group, the SS decreased (p = 0.001), the LL tended to decrease (p = 0.0602), and the TK, CI, and HP remained unaltered. At T1, the SS and LL parameter differed between groups statistically (p = 0.0002 and p = 0.0064, respectively) and clinically (2.52° and 2.58°, respectively). In 7–10-year-old children, participation in dedicated physical activities tends to improve their body posture compared to regular school sport.

The study aimed to determine the impact of 6-month rigid brace on back muscle strength and endurance in adolescents with idiopathic scoliosis. Sixty–one girls, aged 7.0–16.0, were analyzed in two groups: the study group (6–month rigid brace wear) vs. the control group (no brace treatment), recruited consecutively and matched for age, body height, weight, BMI, primary curve location and Cobb angle. All patients underwent clinical and radiological examination, modified Biering–Sorensen test, prone and standing maximum strength and endurance tests. No significant difference between groups in back muscles strength or endurance, both gobal and reported to body weight was found. No relation between the daily brace time and the back muscle strength or endurance was observed. The 6–month use of a rigid brace did not affect the strength or endurance of the back muscles in adolescent girls treated for idiopathic scoliosis.

A standing body height is a variable used to calculate pulmonary parameters during spirometry examination. In adolescents with idiopathic scoliosis, the loss of the body height is observed, and it may potentially influence the results of pulmonary testing. The study aimed to analyze pulmonary parameters in adolescents with idiopathic scoliosis in relation to the measured versus the corrected body height. Preoperative pulmonary testing and radiographic evaluation were performed in 39 children (29 females, 10 males) aged 12–17 years. Forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were measured. The single best effort was analyzed. Thoracic Cobb angle ranged 50°–104°. Corrected body height was calculated according to the Stokes’ formula. The subgroup analysis was performed for the subjects with curves 50°–74° (N=26) versus 75°–104° curves (N=13). Mean measured body height was 166.1±9.0 cm versus 168.9±8.9 cm mean corrected body height. The %FVC obtained for the measured height was significantly higher than obtained for the corrected height: 84.6% ±15.6 vs. 81.6% ±15.6, p

The Global Lung Function Initiative (GLI 2012) presented multi-ethnic spirometry reference values that are recommended to be used instead previous Zapletals’ reference values. The study aimed to compare the values of the pulmonary parameters calculated according to the Zapletals’ versus the GLI 2012 reference values in adolescents with idiopathic scoliosis. Preoperative pulmonary testing and radiographic evaluation were performed in 39 adolescents (29 females, 10 males) aged 12–17 years. The thoracic Cobb angle ranged 50°–104°. Forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were measured. The percentages of predicted values of FVC (%FVC) and the FEV1 (%FEV1) were calculated according to the Zapletals’ reference values and to the GLI 2012 reference values. The subgroup analysis was performed for the subjects with Cobb curve 50°–74° (N=26) versus the subjects with Cobb curve 75°–104° (N=13). Mean %FVC was significantly higher using the Zapletals’ reference values 86.1%±16.4 versus 84.6%±15.6 using the GLI 2012 reference values, p=0.0116. Mean %FEV1 was significantly higher using the Zapletals’ reference values 84.5%±18.2 versus 80.0%±16.3 using GLI 2012 reference values, p=0.000001. The subgroup analysis revealed significant difference of %FVC in moderate (p=0.033974) and no difference in severe curves (p=0.1993). The %FEV1 differences were significant in both moderate (p=0.000011) and severe curves (p=0.0334). The study demonstrated that a significant difference might be observed in the spirometry parameters due to the applied reference values. These differences might be taken into account during the spirometry examination interpretation.

Background The CHD7 (chromosome domain helicase DNA binding protein 7) gene has been associated with familial idiopathic scoliosis (IS) in families of European descent. The CHD7 single-nucleotide polymorphisms have never been studied in Polish Caucasian IS patients. Methods The aim of this study was to investigate the relationship of CHD7 gene polymorphisms with susceptibility to or progression of IS in Polish Caucasian females. The study group comprised 211 females who underwent clinical, radiological and genetic examination. The study group was analyzed in three subgroups according to: (1) Cobb angle (Cobb angle ≤30° vs. Cobb angle ≥35°), (2) age of diagnosis (adolescent IS vs. early-onset IS) and (3) rate of progression (non-progressive vs. slowly progressive vs. rapidly progressive IS). The control group comprised 83 females with no scoliosis and with a negative family history who underwent clinical and genetic examination. In total six CHD7 gene polymorphisms were examined. Three polymorphisms (rs1017861, rs13248429, and rs4738813) were examined by RFLP (restriction fragment length polymorphism) analysis, and three were quantified by Sanger sequencing (rs78874766, rs4738824, and rs74797613). Results In rs13248429, rs78874766, and rs74797613 polymorphisms only the wild allele was present. The rs1017861 polymorphism demonstrated an association with IS susceptibility (p p CHD7 gene showed any association with the age of IS onset. Conclusions The polymorphism rs1017861 in CHD7 gene showed an association with IS susceptibility. Two polymorphisms (rs1017861 and rs4738813) were associated with curve severity and progression rate. None of the evaluated polymorphisms in CHD7 gene showed any association with the age of IS onset. Further evaluation of CHD7 gene should be considered as IS modifying factor.

The aim of this work was to analyze postural stability of girls having progressive form of idiopathic scoliosis and undergoing specific period of the adolescent growth spurt. Twenty-seven girls, aged 13.4 ± 1.2 years, presenting structural idiopathic scoliosis, thoracic or thoracolumbar pattern, radiological Cobb angle 41.7 ± 17.4° (study group) and 37 healthy girls (control group) were included. The groups were sex, age, height, weight, and BMI matched. Postural stability examination was performed using two stabilometric platforms with visual control (eyes open) at three stages: (1) both legs’ stance, (2) left leg stance, and (3) right leg stance. The Center of Pressure (COP) sway path length, the area and the displacement amplitude were compared. For the double stance, no difference in postural stability parameters between the groups was found. However, for the right leg stance, the total sway path length was longer (p=0.04) and the mean amplitude of the lateral COP displacement was increased (p=0.03) in the scoliotic group. In conclusion, for double stance, the adolescent girls with progressive form of idiopathic scoliosis revealed fair postural stability compared to control group. An impaired postural control was observed during right leg stance.

Background The physiological sagittal spinal curvature represents a typical feature of good body posture in the sagittal plane. The cervical and the lumbar spine are curved anteriorly (lordosis), while the thoracic segment is curved posteriorly (kyphosis). The pelvis is inclined anteriorly, and the lower limbs’ joints remain in a neutral position. However, there are many deviations from the optimal body alignment. The aim of this paper is to present the most common types of non-structural misalignments of the body posture in the sagittal plane. Main body of the abstract The most common types of non-structural misalignments of body posture in the sagittal plane are as follows: (1) lordotic, (2) kyphotic, (3) flat-back, and (4) sway-back postures. Each one may influence both the skeletal and the muscular system leading to the functional disturbance and an increased strain of the supporting structures. Usually, the disturbances localized within the muscles are analyzed in respect to their shortening or lengthening. However, according to suggestions presented in the literature, when the muscles responsible for maintaining good body posture (the so-called stabilizers) are not being stimulated to resist against gravity for an extended period of time, e.g., during prolonged sitting, their stabilizing function is disturbed by the hypoactivity reaction resulting in muscular weakness. The deficit of the locomotor system stability triggers a compensatory mechanism—the stabilizing function is overtaken by the so-called mobilizing muscles. However, as a side effect, such compensation leads to the increased activity of mobilizers (hyperactivity) and decreased flexibility, which may finally lead to the pathological chain of reaction within the musculoskeletal system. Conclusions There exist four principal types of non-structural body posture misalignments in the sagittal plane: lordotic posture, kyphotic posture, flat-back posture, and sway-back posture. Each of them can disturb the physiological loading of the musculoskeletal system in a specific way, which may lead to a functional disorder. When planning postural corrective exercises, not only the analysis of muscles in respect to their shortening and lengthening but also their hypoactivity and hyperactivity should be considered.

Low back pain is a massive problem in modern population, both in social and economic terms. It affects large numbers of women, especially those aged 45-60. Going through a perimenopausal period is associated with many symptoms, including low back pain. This paper is a review of published research on the association between the perimenopausal age and low back pain. PubMed databases were investigated. After the search was narrowed to “menopausal status, back pain”, 35 studies were found. Seven studies, which suited our area of research best, were thoroughly analyzed. All studies show increased pain when women enter this period of their life. There is no agreement among researchers regarding which stage of menopause is the most burdensome. Examples of possible treatments and physiotherapeutic methods targeting low back pain are also presented. Physiotherapeutic procedures used to treat low back pain include exercises in safe positions, balance exercises, manual therapy, massage and physical measures.

Background Digital photogrammetry provides measurements of body angles or distances which allow for quantitative posture assessment with or without the use of external markers. It is becoming an increasingly popular tool for the assessment of the musculoskeletal system. The aim of this paper is to present a structured method for the analysis of posture and its changes using a standardized digital photography technique. Material and methods The purpose of the study was twofold. The first one comprised 91 children (44 girls and 47 boys) aged 7–10 (8.2 ± 1.0), i.e., students of primary school, and its aim was to develop the photographic method, choose the quantitative parameters, and determine the intraobserver reliability (repeatability) along with the interobserver reliability (reproducibility) measurements in sagittal plane using digital photography, as well as to compare the Rippstein plurimeter and digital photography measurements. The second one involved 7782 children (3804 girls, 3978 boys) aged 7–10 (8.4 ± 0.5), who underwent digital photography postural screening. The methods consisted in measuring and calculating selected parameters, establishing the normal ranges of photographic parameters, presenting percentile charts, as well as noticing common pitfalls and possible sources of errors in digital photography. Results A standardized procedure for the photographic evaluation of child body posture was presented. The photographic measurements revealed very good intra- and inter-rater reliability regarding the five sagittal parameters and good reliability performed against Rippstein plurimeter measurements. The parameters displayed insignificant variability over time. Normative data were calculated based on photographic assessment, while the percentile charts were provided to serve as reference values. The technical errors observed during photogrammetry are carefully discussed in this article. Conclusions Technical developments are allowed for the regular use of digital photogrammetry in body posture assessment. Specific child positioning (described above) enables us to avoid incidentally modified posture. Image registration is simple, quick, harmless, and cost-effective. The semi-automatic image analysis, together with the normal values and percentile charts, makes the technique reliable in terms of child’s posture documentation and corrective therapy effects’ monitoring.

Background: Patients with Scheuermann disease often require conservative management with a series of corrective casts, followed by anti-kyphotic brace. Flexibility of the kyphosis can be assessed during a supine fulcrum bending test. The aim of the study was to analyze the radiological flexibility of kyphosis and immediate in-cast correction in a series of patients conservatively treated.Methods: Eighty-six adolescents were conservatively treated for Scheuermann disease of thoracic location. Charts of 55 patients, 39 boys and 16 girls, were accessible. The mean age was 14.6±1.6 years. On the lateral full-cassette standing radiograph, the angle of thoracic and lumbar lordosis were measured. The flexibility of kyphosis was assessed on a supine fulcrum bending lateral radiograph. The in-cast kyphosis angle was measured on a standing lateral radiograph.Results: In 18 patients, a mild non-progressive scoliotic curvature was present; it did not exceed a Cobb angle measurement of 25°. The initial kyphosis angle was 59.2°±9.3°. The lordosis angle was 76.3°±9.3°. The kyphosis angle on supine fulcrum bending test was 30.4°±9.7°. The kyphosis angle in the reclining cast was 44.3°±12.5°. There was no correlation between age and the supine bending correction. There was a correlation between the correction obtained with the supine bending test and the immediate correction in the cast (r=0.64, p=0.0012).Conclusions: The reduction of the kyphosis Cobb angle by supine fulcrum bending was 50% on average, while in the cast in standing position, only half of this correction was maintained.

Background First author attempted to analyse medical records of patients with idiopathic scoliosis for compliance with the Scoliosis Research Society brace studies criteria. A retrospective analysis of medical records of 2705 girls treated from 1989 to 2002 was carried out. Methods Age, Cobb, Risser and menarchal status were analyzed for compliance with the Scoliosis Research Society brace studies criteria: a) age ≥10 years, b) Risser 0–2, c) 25–40° Cobb angle, d) no earlier treatment, e) patients before first menses or not more than one year from first menses. Results It has been found that 183 girls out of 2705 were ≥10 years old and in the range 25–40° Cobb angle. One hundred two out of 2705 patients revealed eligible for brace effectiveness study according to SRS 2005 criteria. 120 out of 2705 patients revealed eligible for brace brace effectiveness study according to SRS-SOSORT 2014 criteria. Conclusion The excluded patients revealed too old or with too significant Cobb angles. This indicates the changing criteria for scoliosis brace treatment over the time. Direct comparison of current results of brace treatment with historical series of cases turns out to be very difficult.

According to the Scoliosis Research Society (SRS), idiopathic scoliosis (IS) is a curvature of more than 10° Cobb angle, affecting 2-3% of pediatric population. Idiopathic scoliosis accounts for 80% of all scoliosis cases. Non-operative principles in the therapy of idiopathic scoliosis, including Scoliosis Research Society (SRS) criteria and guidelines proposed by the experts of the Society on Scoliosis Orthopedic and Rehabilitation Treatment (SOSORTS) were presented. The possibility to carry out quality of life assessments in a conservative procedure was also demonstrated. Based on the natural history of idiopathic scoliosis, SRS criteria, SOSORT 2008 experts' opinion and the knowledge of the possibilities of psychological assessment of conservative IS treatment, rules were proposed regarding nonsurgical IS therapy procedures, with special consideration being paid to the proper treatment start time (age, Risser test, biological maturity, Cobb angle), possibility of curvature progression, the importance of physiotherapy and psychological assessment. The knowledge of SRS criteria and SOSORT guidelines regarding the conservative treatment of IS are essential for proper treatment (the right time to start treatment), and supports establishment of interdisciplinary treatment teams, consisting of a physician, a physiotherapist, an orthopedic technician and a psychologist.

Background Digital photography for a 2-dimensional assessment of the body shape is a valuable method to both document the human posture and calculate the main quantitative parameters of it. Purpose The goal of this study was to assess the frontal plane symmetry of the anterior trunk in healthy school children based on the digital photography by measurement of the Anterior Trunk Symmetry Index (ATSI). . Methods The study comprised 421 school children, both sexes, aged 7-10 years, with no clinical evidence of scoliosis (Angle of Trunk Rotation

Methods The study group included 147 Caucasian girls with IS, aged 9-18 years (mean 13.6 ±2.2), Cobb angle range 11°65°, mean 27.9 ±11.9, comprising 42 single thoracic, 31 single lumbar and 74 double curve scoliosis. According to the Cobb angle, there were 70 mild (10-24o), 54 moderate (25-40o) and 23 severe (> 45o) curves. The control group included 147 girls aged 9-18 years (mean 13.1 ±.3), selected at random from the group of 300 girls free of IS (angle of trunk rotation

Background Environmental and genetic factors have influence on the age at menarche (AAM). Disturbance of the AAM in patients with idiopathic scoliosis (IS) were postulated [1]. Estrogen receptor genes 1 and 2 (ESR1, ESR2) single nucleotide polymorphisms (SNP) in IS were suggested to have some association with predisposition to IS [2]. ESR SNPs were reported to have association with AAM in healthily females [3].
