Objectives. The aim of the study was to assess the change of sagittal spinal curvatures in children with generalized joint hypermobility (GJH) instructed with "straighten your back" command (SYB). Methods. The study included 56 children with GJH. The control group consisted of 193 children. Sacral slope (SS), lumbar lordosis (LL), global thoracic kyphosis (TK), lower thoracic kyphosis (LK), and upper thoracic kyphosis (UK) were assessed with Saunders inclinometer both in spontaneous positions (standing and sitting) and after the SYB. Results. Children with GJH after SYB presented the following: in standing, increase in SS and decrease in TK, LK, and UK (P<0.01), with LL not significantly changed; in sitting: decrease in global thoracic kyphosis (35.5° (SD 20.5) versus 21.0° (SD 15.5), P<0.001) below the standards proposed in the literature (30-40°) and flattening of its lower part (P<0.001). The same changes were observed in the control group. Conclusions. In children with generalized joint hypermobility, the "straighten your back" command leads to excessive reduction of the global thoracic kyphosis and flattening of its lower part. Therefore, the "straighten your back" command should not be used to achieve the optimal standing and sitting positions. © 2017 Dariusz Czaprowski et al.

Electronic rulers on computer screen are used to measure the Cobb angle (CA) instead of traditional methods with rulers, protractors and pens. The variety of software used to assess radiographs might make the CA measurements cumbersome in everyday clinical practice.The aim of the study was to verify the method of CA measurements on digital radiographs using Bunnell scoliometer (BS).Eighty patients with idiopathic scoliosis were enrolled into the study. CA of each curve was measured by use of Centricity software and BS. CA on 30 randomly chosen patients were measured 3 times by one researcher using only scoliometer. Three researchers measured CA on the same 30 radiographs using BS.The mean CA of 224 curves measured by Centricity and BS were 29 12.2 and 28 11.7, respectively. The ICC for agreement for 2 methods was 0.96 with SEM of 1.7. Excellent intra- and interobserver reliability of CA measurements with scoliometer was noted: ICC of 0.96 with SEM of 1.4 and ICC of 0.93 with SEM of 1.9, respectively.The study revealed excellent reliability of CA measurements on digital radiographs using the BS. The proposed method of using the Bunnell scoliometer for CA measurements may be clinically useful.

Background. According to the requirements of Evidence Based Medicine, every research tool and method should be subjected to reliability evaluation. A variety of inclinometers are used for the assessment of sagittal plane spinal curvatures in clinical practice. The aim of the study was to evaluate the intra- and interobserver repeatability of measurements of the anteriorposterior spinal curvatures taken with Saunders digital inclinometer. Material and methods. The study involved 30 healthy subjects (5 males, 25 females) aged 20 to 35 years. The anteroposterior curvatures of the spine were measured in all subjects using a Saunders digital inclinometer. In order to evaluate the intraobserver repeatability of measurements, the results obtained by one investigator were compared. To evaluate interobserver repeatability, the results obtained by three investigators were compared. Additionally, the levels of reliability and measurement error were determined. Results. The measurements conducted by one investigator showed good repeatability for sacral slope, lumbar lordosis, and thoracic kyphosis, including the angle of proximal (Th1-Th6) and distal (Th6-Th12) thoracic kyphosis (p>0.05). For measu - rements taken by three investigators, interobserver repeatability was achieved for thoracic kyphosis (p>0.05). The reliability of the measurements was good (Cronbach's alpha was 0.9> α ≥0.8), and the measurement error was between 2.8° - 3.8°. Conclusions. 1. The assessment of anteroposterior curvatures of the spine by one investigator provided good repeatability and reliability of measurements. 2. Measurements performed by more than one investigator displayed partial repeatability. 3. The value of the observational error should be taken into account in the interpretation of results of measurements performed with the Saunders inclinometer. 4. The assessment of anteroposterior curvatures of the spine should be preceded by a verification of measurement reliability. © MEDSPORTPRESS.

The aim of the study was to evaluate changes in hamstring flexibility in 120 asymptomatic children who participated in a 6-week program consisting of one physiotherapy session per week and daily home exercises. The recruitment criteria included age (10-13 years), no pain, injury or musculoskeletal disorder throughout the previous year, physical activity limited to school sport. Subjects were randomly assigned to one of the three groups: (1) post-isometric relaxation - PIR (n = 40), (2) static stretch combined with stabilizing exercises - SS (n = 40) and (3) stabilizing exercises - SE (n = 40). Hamstring flexibility was assessed with straight leg raise (SLR), popliteal angle (PA) and finger-to-floor (FTF) tests. The examinations were conducted by blinded observers twice, prior to the program and a week after the last session with the physiotherapist. Twenty-six children who did not participate in all six exercise sessions with physiotherapists were excluded from the analysis. The results obtained by 94 children were analyzed (PIR, n = 32; SS, n = 31; SE, n = 31). In the PIR and SS groups, a significant (P<0.01) increase in SLR, PA, FTF results was observed. In the SE group, a significant (P<0.001) increase was observed in the SLR but not in the PA and FTF (P>0.05). SLR result in the PIR and SS groups was significantly (P<0.001) higher than in the SE group. As far as PA results are concerned, a significant difference was observed only between the SS and SE groups (P = 0.014). There were no significant (P = 0.15) differences regarding FTF results between the three groups. Post-isometric muscle relaxation and static stretch with stabilizing exercises led to a similar increase in hamstring flexibility and trunk forward bend in healthy 10-13-year-old children. The exercises limited to straightening gluteus maximus improved the SLR result, but did not change the PA and FTF results. © 2013 Czaprowski et al.

Joint laxity is diagnosed when the mobility of small and large joints is increased in relation to standard mobility for any given age, gender and race, and after excluding systemic diseases. Many of authors noted the co occurrence of joint laxity with the following symptoms: back and joints pa in, as well as disturbance of body posture. Clinicians apply various methods to assess joint laxity. Beighton scale is the most frequent method used in clinical screening. It consists of assessing: extension of the fifth MPC joint to 90°, thumb abduction to front fore arm, hyperextension of el bow and knee joint above 10°, as well as capability to stand bend and place onés palms flat on the ground. Carter and Wilkinson method is similar to this scale. The difference concerns the assessment of passive hyperextension of all four II-V fingers, instead of the assessment of the fifth finger only. The second difference involves assessing the range of an kledorsi flexion, in stead of assessing the ability to touch the ground with onés palms. Marshall test is another method for assessing joint laxity. This test is based on the thumb motion range measured in the fore arm direction. Hakim and Grahame suggests that the diagnosis of joint laxity may be done with a 5-point questionnaire. It would al low a fastove review as its questions refer to symptoms observed both at pre sent and in the past. Taken into account the common occurrence of joint laxity as well as common use the flexibility exercises in the physiotherapeutic process, the joint laxity should be systematically assessed by both physicians and physiotherapists. © MEDSPORTPRESS, 2012.

Objective. The aim of this work was to define the prevalence of back pain in children and youth aged 10-19 from the southeast of Poland. Material and Methods. The cross-sectional study included 1089 students (547 girls and 542 boys) aged 10-19. The prevalence of back pain, its intensity, location, and situations in which it occurred were assessed with a questionnaire. Results. Among 1089 respondents, 830 (76.2%) admitted that they had experienced back pain at various frequencies within the year preceding the study. Back pain was located mainly in the lumbar segment (74.8%). Mild pains were dominant, which was declared by 44.7% of the respondents. Girls experienced back pain significantly more frequently than boys (52.2% versus 47.8%, P < 0.05). Conclusions. The research revealed that back pain is a common phenomenon. The prevalence of back pain in children and youth living in southeast Poland is similar to the frequency of occurrence of such complaints occurring in peers in other countries. It seems significant to monitor the remaining regions of Poland in order to define the scale of the problem and to look for the risk factors of back pain in children and youth to undertake efficient prophylactic actions. © 2013 Agnieszka Kȩdra and Dariusz Czaprowski.


Background. Children commonly attend exercise programs to correct abnormal sagittal curvatures of the spine. The presence of generalized joint hypermobility (JH) is often disregarded during exercise planning. The aim of the study was to assess the influence of JH on the sagittal curvatures of the spine. Material and methods. The JH group included 38 girls and 37 boys aged 10-13 years with known JH (Beighton test cut-off ≥5 points for girls, and ≥4 for boys). A control group included 197 girls and 150 boys. The children were matched for age, height, weight and BMI. The sacral slope (SS), lumbar lordosis (LL), tho racic kyphosis (TK), distal thoracic kyphosis (DK), and proximal thoracic kyphosis (PK) were assessed with a Saunders inclinometer. The results in children with and without JH were compared. Results. There were no significant (p>0.05) differences between girls with and without JH with respect to SS (22.5°±9.9 vs 23.0°±8.0), LL (31.0°±14.0 vs 33.0°±10.0), TK (39.0°±10.4 vs 39.6°±10.0), DK (8.7°±6.9 vs 7.9°±7.8) or PK (31.3°±7.1 vs 32.3°±7.3). The differences among boys were similarly non-significant (p>0.05) (19.0°±7.9 vs 19.7°±6.6; 30.6°±9.0 vs 31.9°±8.4; 42.7°±8.0 vs 40.6°±8.7; 9.7°±7.9 vs 8.2°±7.8; 33.7°±5,0 vs 32.8°±7.0, for SS, LL, TK, DK and PK, respectively). Conclusions. 1. The sagittal profile of the spine did not differ between children with and without JH, which may lead to suboptimal exercise plans. 2. The routine examination of the musculoskeletal system should be extended to include an assessment of JH. © MEDSPORTPRESS, 2013.

The surface electromyography (sEMG), by evaluating the paraspinal muscle activity, may be used for diagnosis and evaluation of rehabilitation effectiveness patients with low back pain.The purpose of the study was to determine the intra- and inter-session reliability of the measurement of the activity of the lumbar erector spinae (LES) activity (extension-flexion ratio).The study included 21 asymptomatic subjects, aged 14 to 27 years, mean 23.7 2.9. The LES muscle activity was assessed with using of the sEMG during forward trunk flexion and extension by two examiners. Based on the quotient of the LES muscle activity obtained during four concentric and eccentric tasks the extension-flexion ratio was calculated.The measurements displayed excellent or fair-to-good reliability (intraclass correlation coefficient ranged from 0.90 to 0.68). The typical error and coefficient of variations, ranged from 0.34 to 0.58, and from 13.7 to 21.9, respectively.The measurement of the extension-flexion ratio performed with the use of sEMG shows high level of intra- and inter-session reliability, suggesting that this parameter is a reliable tool in evaluation of the lumbar paraspinal muscles activity. However, the level of typical error should be taken into account.

Three-dimensional gait analysis is commonly used in the objective evaluation of children with idiopathic scoliosis. However, interpretation of results requires carefulness because the gait measurements are error prone. Assessing the reliability of gait analysis in each laboratory may be contribute to assess sources and magnitude of errors in gait analysis as well as determine the direction of the training of examiners.

The ability to adopt the properly corrected body posture is one of the factors determining the effectiveness of therapeutic programmes. This study determined the active self-correction expressed by the change of sagittal spinal curvatures (in standing and sitting positions) in 249 children (136 females, 113 males, aged 10-14 years) instructed with straighten your back command (SYB). Spinal curvatures (sacral slope-SS, lumbar lordosis-LL, global, lower and upper thoracic kyphosis-TK, LK, UK, respectively) were assessed using Saunders inclinometer. The assessment was done in spontaneous standing and sitting positions and in the positions adopted after the SYB. In a standing position SYB led to the significant (P<0.001) increase in SS, and the significant (P<0.01) decrease in LL, TK, LK, UK. In a sitting position SYB led to significant changes (P<0.001) from kyphotic to lordotic position of SS and LL and to the significant (P<0.001) reduction of TK (36.510.8 vs. 23.511) and the flattening of LK (15.28.7 vs. 1.08.4). There were gender-based discrepancy regarding active self-correction only for LL in a standing and UK in a sitting position. Females demonstrated a significant decrease in LL (P<0.001). UK significantly increased only in males (P<0.001). The straighten your back command leads to moving the spine away from mid-range towards end range of motion. Therefore, the command should not be used to elicit the most optimal back posture. Further studies are needed to determine if the active self-correction is different in females and males.
