Objectives: This paper assesses the effect of neurophysiological rehabilitation in children with postural defects on the depth of thoracic kyphosis, lateral spinal deviation and rotation of spinal motor segments. Material and Methods: A total of 201 patients aged 8-15 years old with a postural defect diagnosed by medical examination were enrolled. The analyzed parameters were determined using the DIERS system before the first therapeutic session and after 4 weeks of therapy. The angle of thoracic kyphosis, lateral deviation of the spine and spinal rotation were assessed. The therapy employed techniques associated with the proprioceptive neuromuscular facilitation (PNF) and Vojta's approaches. The results were analyzed separately for both sexes and for patients rehabilitated solely with Vojta's techniques vs. patients rehabilitated according to combined Vojta's and PNF techniques. The χ 2 test was used for statistical analyses, at p < 0.05. Results: There was improvement in the angle of thoracic kyphosis, ranging from 0.14 (among boys with kyphosis < 42°) to 5.47 (among girls with kyphosis ≥ 42°), spinal rotation, from 0.37 (among boys with kyphosis ≥ 42°) to 4.33 (among patients with kyphosis ≥ 42° rehabilitated solely according to Vojta's method), and lateral deviations, ranging from 1.32 mm (among boys with kyphosis < 42°) to 2.99 mm (among patients with kyphosis ≥ 42° rehabilitated solely according to Vojta's method). Conclusions: Neurophysiological rehabilitation of patients with postural defects produced positive effects by improving the angle of thoracic kyphosis, spinal rotation and lateral deviation of the spine. Children with reduced thoracic kyphosis achieved less improvement in the kyphosis angle, lateral spinal deviation and spinal rotation than children with kyphosis ≥ 42°. The DIERS Formetric System enables precise monitoring of therapeutic outcomes.

The eating habits of students differ significantly from those recommended by health practitioners. The aim of this study was to find differences related to diet quality and knowledge on nutrition among Polish, German, and Slovakian students as well as to examine which factors differentiate the diet quality of students from these three countries. The study was conducted on a group of 394 university students from Poland, Germany, and Slovakia. The assessment of diet quality and knowledge on food and nutrition was done with the use of the Dietary Habits and Nutrition Beliefs Questionnaire. The diet of German students was characterized by a significantly higher consumption of legume-based foods, vegetables, and fruit compared to Polish students and Slovakian participants (p < 0.001). The diet of the Poles was characterized by a high consumption of cured meat, smoked sausages, hot dogs, white bread and bakery products, butter, fried foods, and energy drinks. The most important factors significantly associated with diet quality involved the country, place of residence, Body Mass Index (BMI), physical activity, and time spent watching TV or using a computer. Polish students were characterized by the highest level of knowledge on food and nutrition (p < 0.001). However, it was not reflected in their diet. The authorities of universities should aim to provide students with access to canteens on campuses which would offer the possibility of consumption of both affordable and healthy meals.

ICG R15 is reliable within one group at defined perfusion rates. Doubled perfusion rates contribute to higher ICG clearance. For clinical application we would like to suggest considering cardiac output of the patient for interpretation of ICG ratios.

In multiple sclerosis (MS), gait impairment is one of the most prominent symptoms. For a sensitive assessment of pathological gait patterns, a comprehensive analysis and processing of several gait analysis systems is necessary. The objective of this work was to determine the best diagnostic gait system (DIERS pedogait, GAITRite system, and Mobility Lab) using six machine learning algorithms for the differentiation between people with multiple sclerosis (pwMS) and healthy controls, between pwMS with and without fatigue and between pwMS with mild and moderate impairment. The data of the three gait systems were assessed on 54 pwMS and 38 healthy controls. Gaussian Naive Bayes, Decision Tree, k-Nearest Neighbor, and Support Vector Machines (SVM) with linear, radial basis function (rbf) and polynomial kernel were applied for the detection of subtle walking changes. The best performance for a healthy-sick classification was achieved on the DIERS data with a SVM rbf kernel (k = 0.49 ± 0.11). For differentiating between pwMS with mild and moderate disability, the GAITRite data with the SVM linear kernel (k = 0.61 ± 0.06) showed the best performance. This study demonstrates that machine learning methods are suitable for identifying pathologic gait patterns in early MS.

Objectives The current understanding of hypermobility and its diagnostic criteria is still insufficient to create a complete and systematic clinical presentation of the disorder. The objective of this study was to assess the prevalence of joint hypermobility syndrome (JHS) amongst a cohort of jazz dancers, by analyzing its presence in accordance with a number of diagnostic criteria, and to verify potential risk factors for joint hypermobility in jazz dancers. Methods 77 jazz dancers from the Polish Dance Theater were examined (58 female and 19 male). The prevalence of JHS was assessed using the following diagnostic tools: a structured interview, Beighton score, Grahame & Hakim questionnaire, and Sachse’s criteria, in the modified version proposed by Kapandji. Results The prevalence of JHS in this cohort of jazz dancers differed significantly, depending on which criteria were adopted (p = 0.001) with Beighton score, Grahame & Hakim questionnaire, and Sachse’s criteria identifying 64.9%, 74% and 59.7% of the sample as JHS respectively. Hypermobility was significantly more prevalent in women than men (p < 0.05). Conclusions This study demonstrated a significant prevalence of joint hypermobility in jazz dancers and corroborates the findings of other researchers, indicating the need for unified diagnostic criteria for JHS in dancers.

Introduction Balance is key to controlling body posture. Balance is typically assessed by measures of the body’s vertical orientation, obtained by balancing out the forces acting on different body segments. The ability to maintain balance is assessed by evaluating centre of pressure (CoP) displacement; such assessments are typically used to evaluate responses to a treatment process. Purpose of study This study evaluated the efficiency of compensatory reactions in children according to the extent of thoracic kyphosis and lumbar lordosis. Materials and method The study enrolled 312 children aged 8‒12 years, including 211 patients with postural disorders: thoracic kyphosis outside the 47‒50-degree range and lordosis outside the 38‒42-degree range (study group). A control group was also recruited and comprised 101 children without postural disorders. The DIERS formetric 4D system was used to assess posture and CoP displacement. Results Children in the study group showed a significantly greater range of CoP displacement than children in the control group. The kyphosis angle correlated with the maximum CoP displacement in the coronal plane and the maximum CoP displacement in the sagittal plane during gait. The kyphosis angle also correlated with the maximum CoP displacement back in the static test. The size of the lordosis angle correlated with the maximum displacement of CoP in the coronary plane during gait, and with the maximum displacement of CoP toward the left, forward, and backward in the static test. The correlation coefficient of the lordosis angle with displacement of the CoP in the sagittal plane was 0.999. Conclusions We found an association between kyphosis and lordosis and the amplitude of CoP displacement, which may reflect the postural control system’s response to biomechanical destabilisation caused by changes in kyphosis and lordosis. The lordosis angle correlation strength for displacement of CoP in sagittal plane is 0.999 and adopts a linear value.

Background The FED method (Fixation, Elongation, Derotation) is a treatment method approach to Patients with scoliosis. The FED method is especially established in Spain and Poland, whereby in Germany it is less well-known. Nevertheless the FED method is within the scope of a research project (Project Number: 19200 BR/3). The purpose of the paper is to characterize the FED method and to highlight the specificities in contrast to the Schroth method, which is international established and especially in Germany. Methods This systematic literature research was conducted in Nov 2017–Jan 2018. Therefore common medical and physiotherapeutic databases were used. Furthermore there was a hand search in selected scientific journals. Only a small number of relevant references were identified. That is why the respective authors were asked to provide the full-texts of their papers and to recommend further references. Results A total of 378 references were identified. After removing duplicates and the content-related selection, 19 references were deemed to be relevant. Based on the analysis of this relevant literature, the FED method was comprehensively characterized. First of all the general structure of the FED method and the scientific evidence for its effectiveness was described. And as a result of the literature research, the operating principles of the FED method were pointed out. Then these operating principles were discussed in comparison with the Schroth method. The Schroth method based on sensomotoric and kinesthetic principles and the correction of the pathologic posture was performed by selective muscle activation and breathing-pattern. Thus, the posture correction will be performed by the patients (auto correction). Compared to the Schroth method, the FED method implements the posture correction by the FED-device. This correction is influenced by mechanical forces with a comparatively high strength and intensity. The repetitive mechanical correction stimulates the sensomotoric system. And due to trophic/biochemical adaptations, the physiological bone growth will be stimulated. Conclusion In total the authors want to clarify, that both treatment methods (Schroth method, FED method) supposed to be applied in consideration of the preconditions of the patients and the pursue of the different treatment goals. Thus, the implementation of treatment methods should be used according to the individual treatment demand and on different stages in the treatment process.

Objectives: This paper evaluates the efficacy of using the McKenzie and Vojta methods for patients with low back pain and the use of the DIERS Formetric 4D system as an objective diagnostic tool. Material and Methods: The study enrolled 28 patients aged 15-17 years old. The patients were hospitalized at the Department of Orthopedics and Traumatology of the Świętokrzyskie Center for Pediatrics in Kielce with a diagnosis of back pain associated with a discopathy. The patients were rehabilitated according to the McKenzie and Vojta methods. Assessment by means of the DIERS Formetric system had taken place before the first therapy session and on the day that pain was eliminated to evaluate trunk inclination, angle of thoracic kyphosis, angle of lumbar lordosis, lateral deviation, trunk torsion, surface rotation and pelvic obliquity. Pain intensity and change in pain intensity over time were assessed by means of a numerical rating scale. Results: Pain intensity was reduced to 0 over 3-12 days. The study participants demonstrated reduction in anterior trunk inclination of the mean value at 1.83°. The angle of thoracic kyphosis was also reduced by 7.95°. The angle of lordosis increased by 7.6°. The lateral spinal curvature was reduced by 8.92 mm. There was a reduction of 4.64° in trunk torsion. Surface rotation was reduced by 1.61° and pelvic obliquity was reduced by 3.78°. Conclusions: In discopathic patients, postural parameters comprising trunk inclination, angle of thoracic kyphosis, angle of lumbar lordosis, lateral deviation, trunk torsion, vertebral rotation and pelvic obliquity fail to reach Hartzmann's physiological reference ranges. A therapeutic intervention based on the Vojta and McKenzie methods may normalize the posture to physiological reference ranges and is effective in the treatment of patients with back pain. The DIERS system is an objective tool for tracing the effects of therapy in patients with back pain.
