The title of the master thesis: Clinical evaluation of ROM of shoulder joint in cadet and junior category players of so-called overhead sports Abstract in English language: The goal of this thesis is to elucidate whether the "overhead" athletes like handballers and volleyballers suffer from extension changes and local hypermobility in their shoulder joints. These changes are going to be described by trigonometric measurements and hypermobility tests by Sachse. It is going to be determined which "overhead" athletes are affected the most. Their sex is going to be taken into consideration. The theoretical part of the thesis describes selected "overhead" sports and their strain on a human body from a kinesiologic point of view. Especially the impact of offensive blows in volleyball and throws in handball on shoulder joints are going to be examined. The thesis is going to examine a shoulder girdle from an anatomy, kinesiology, biomechanics, and physiology point of view. A chapter focused on hypermobility and it is classification is included too. 95 people without a prior injury of a shoulder joint in the age from 16 to 19 years old including 73 "overhead" athletes were tested. There were 30 men, 40 women, 34 handballers, and 39 volleyballers. In the control group, there were 22 people, of which 11 men and 11...

Gymnastics is noted for involving highly specialized strength, power, agility and flexibility. Flexibility is perhaps the single greatest discriminator of gymnastics from other sports. The extreme ranges of motion achieved by gymnasts require long periods of training, often occupying more than a decade. Gymnasts also start training at an early age (particularly female gymnasts), and the effect of gymnastics training on these young athletes is poorly understood. One of the concerns of many gymnastics professionals is the training of the spine in hyperextension—the ubiquitous ‘arch’ seen in many gymnastics positions and movements. Training in spine hyperextension usually begins in early childhood through performance of a skill known as a back-bend. Does practising a back-bend and other hyperextension exercises harm young gymnasts? Current information on spine stretching among gymnasts indicates that, within reason, spine stretching does not appear to be an unusual threat to gymnasts’ health. However, the paucity of information demands that further study be undertaken.

Abstract Background: Musculoskeletal discomfort is common among professional orchestra musicians and according to the literature some anatomical areas, such as the neck, upper back and upper extremities, seem to be more frequently affected than others. There are also suggestions made that general joint hypermobility could be a potential risk factor for musculoskeletal discomfort among musicians. Furthermore, there seems to be a higher perceived feeling of psychosocial demands and stress among musicians in comparison to the general workforce. Aim: Investigate the prevalence of, and associations between, musculoskeletal discomfort, general joint hypermobility, psychosocial factors and stress among Swedish big band musicians. A further aim was to investigate associations between musculoskeletal discomfort, general joint hypermobility, psychosocial factors and stress, respectively. Method & Material: This study was part of a larger national survey on professional orchestra musicians in Sweden. This study focused on professional jazz musicians and included data from all three professional big bands in Sweden. The study presents the prevalence of musculoskeletal discomfort, general joint hypermobility, psychosocial factors and stress among professional Swedish big band musicians. 32 musicians completed the survey. Results: The study showed a high prevalence of musculoskeletal discomfort and general joint hypermobility. There were no statistically significant relationships between musculoskeletal discomfort and general joint hypermobility but between psychosocial demands and musculoskeletal discomfort in the anatomical subgroup low back/hip, and between negative stress and musculoskeletal discomfort in the anatomical subgroup low back/hip. Conclusion: In accordance with existing studies on classical orchestra musicians, this study found a high prevalence of musculoskeletal discomfort and general joint hypermobility among Swedish big band musicians. There was a statistically significant association with the relationship between psychosocial demands and musculoskeletal discomfort in the anatomical subgroup low back/hip and between negative stress and musculoskeletal discomfort in the anatomical subgroup low back/hip. Key words: big band musicians, musculoskeletal discomfort, general joint hypermobility, psychosocial factors, stress.

Purpose: The aim of this research was to determine whether there is a difference in the presence of minimal cerebellar signs, hypermobility and dyspraxia in the group of patients with idiopathic scoliosis (IS) and a control group of individuals without IS. Methods: 11 patients have been selected for this research with IS and 11 individuals without IS as a control group. The International Cooperative Ataxia Rating Scale (ICARS) was used for examination of cerebellar signs. Hypermobility was evaluated with ten tests according to Janda. The presence of pendulum reflexes was determined by examination of patellar and triceps reflex, while dyspraxia was analyzed by means of the Czechoslovak test. Results: Patients with IS scored significantly worse in ICARS than the control group (p < 0,05). IS patients presented with significantly more pronounced hypermobility in head rotation (p = 0,0384) and forward bending (p = 0,0409) tests comparing to the control group. No significant difference between the two groups was identified in pendulum reflexes and the Czechoslovak dyspraxia test. Conclusion: The study confirms significantly more positive signs of ataxia and asynergy in a group of patients with IS comparing to control group. Hypermobility was significantly more pronounced in head rotation and forward...

<p>Osteoarthritis (OA) is the most common joint disorder causing chronic disability in the world population. By the year 2030, an estimated one fifth of this population will be affected by OA. Although OA is regarded as a multi-factorial disorder with both environmental and genetic components, the exact pathogenesis remains unknown. </p><p> In this study, we hypothesize that biomarkers associated with OA can be used as quantitative traits of OA, and provide enough power to identify new genes or replicate known gene associations for OA. We established an extensive family called the CARRIAGE (CARolinas Region Interaction of Aging, Genes and Environment) family. Then, we measured and analyzed seven OA-related biomarkers (HA, COMP, PIIANP, CPII, C2C, hs-CRP and GSP) in this extensive family to evaluate their association with OA clinical phenotypes. These findings suggest that OA biomarkers can reflect hand OA in this large multigenerational family. Therefore, we performed nonparametric variance components analysis to evaluate heritability for quantitative traits for those biomarkers. Finally, based upon OA biomarkers with high heritability, we performed a genome-wide linkage scan. Our results provide the first evidence of genetic susceptibility loci identified by OA-related biomarkers, indicating several genetic loci potentially contributing to the genetic diversity of OA. </p><p> Meanwhile, we identified joint hypermobility as a factor which reduces OA risk and has an inverse association with serum COMP levels in this family. The relationship between lower serum COMP and OA have been further validated in another Caucasian GOGO (Genetics of Generalized Osteoarthritis) population. Therefore, we further hypothesize that joint hypermobility, having the characteristic of a decreased OA risk, can serve as a quantitative trait for identifying protective loci for OA. Then, we performed nonparametric variance components analysis to evaluate the heritability of joint hypermobility. The result also shows joint hypermobility has substantial heritable components in this family. Lastly, based on the same genome-wide linkage scan, we identify genetic susceptibility loci for joint hypermobility. </p><p> In conclusion, our work provides the first linkage study to identify genetic loci associated with OA using biological markers. Furthermore, we have also shown genetic susceptibility loci for joint hypermobility, possibly implying protective loci for OA.</p> / Dissertation

Author: Bc. Marie Zasadilová Title: Incidence of Joint Hypermobility Syndrome in Anxienty Patients Objectives: The aim of this study is to find out what ist he incidence of Joint hypermobility syndrome in the research group of probands with anxiety disorder, on the base of collected theoretical knowledge. Methods: The group of patients with diagnosis of anxiety disorder was examined on presence of joint hypermobility syndrome. For the examination was used standardised test scale Beighton score. The data was statistically processed, prevalence of hypermobility in the research group was compared with prevalece in common population. Results: Prevalence of joint hypermobility syndrome in the research group was 44,88%, that is about 31,88% more, than in common population. Hypermobility was found in 65% of female part oft he research group, that is about 25% more, than in common female population. Prevalence in male part of research group was 16,67%, about 5,17% more than in common male population. The hypotesis, that prevalence of joint hypermobility syndrome will be hihger in the research group than in common population, was affirmed. Average result of Beighton score in group of probands was 4,38 points, the most common result was 2 points. Skewness and krtosis of the histogram curve corresponds with...
