A B S T R A C T T I T L E The Impact of physical activities in water on joints movements of seniors. O B J E C T I V E The evaluation of the impact of physical activities in water on joint movements of elderly people. From the data available which measures the movements of shoulder and hip joints at the beginning, in the middle and after the training session, we identify whether there are some changes in the range of movements available of the tested joints. M E T H O D The efficiency of swimming program whose duration was 15 weeks was evaluation by measuring the improvement of movements possible of shoulder and hip joints. There were two groups of elderly people tested. The first group consisted of university students taking courses for elderly people, the latter group consisted of elderly volunteers. Both programmes had the same content. R E S U LT S After the swimming program finished, there were measurable changes in the range of joint movements all participants could perform. In majority of cases these changes were positive (i.e enlargement of the range available), in some case the rotation of the joint in certain movements remained same but there were some elderly people whose range of joint movements was reduced. Overall, the range enlargement was estimated to be higher by 5 - 10ř. K E Y W O R D S...

Thesis title: Prevalence of hypermobility and its potential impact on ice hockey players injuries. Objectives: The primary goal of this thesis is to outline joint hypermobility based on available literature sources. Focus is on ice hockey players due to reason ice hockey is muscle and contact based sport. Secondary goal is to chart hypermobility presence on ice hockey players and detect possible connection between hypermobility and their previous musculoskeletal system injuries. There will be training improvement suggestions set according to analytical study results. Methods: Theoretical part is based on foreign literature and researches. Practical part quantitative analysis monitors selected joints injury frequency and is focused on joint hypermobility presence in selected junior professional male hockey players, 16 to 19 years old. Information regarding injuries where gathered by questionnaire and joint hypermobility test was set by test battery created for this research using clinical physical tests by Janda, by Sachse, and by Hospital del Mar criteria. Results were analyzed in Microsoft Excel 2010. Hypermobility and injured segments matches were further analyzed. Results: Results of this thesis clearly stated the answers for research questions which were placed. Prevalence of hypermobility in...

This thesis focuses on the introduction with the problems of high molecular weight polyethylene (UHMWPE) in orthopedics in the first part. It discusses the history, properties and processes that lead to the failure of UHMWPE joint replacement components. The experimental part validates the hypotheses expressed. It acquaints readers with the experimental verification of the effect of different types of sterilization on the oxidative stability of laboratory prepared samples and explanted UHMWPE joint replacement components using methods of infrared microscopy, electron spin resonance, mechanical tests and tests of microhardness. Other experimental measurements on a large set of explanted components of hip and knee total joint replacements validates the hypothesis that the amount of oxidative damage affects the lifespan of joint replacements. The third part of the experimental study maps the degree of oxidative damage in different places of the hip and knee joint replacements. In the final part we experimentally demonstrate the fact that the rate of oxidative damage has an effect on supramolecular structure of the UHMWPE. From the above experiments are concluded clearly defined recommendations for clinical practice, which should lead to extend the lifespan of total joints replacements in orthopaedics....

Title: The relationship of flexibility and movement in gymnastic sports Aims: The purpose of this thesis is to demonstrate the importance of flexibility in relation to performance in gymnastic sports - artistic gymnastics, modern gymnastics, trampoline and sport aerobics. Also, said thesis focuses on attributes related to the range of motion in joint connections from the point of aesthetic criteria, the efficient movement technique, and also from the point of medical prevention. Methods: This task is non-experimental, based on the guided interview with different trainers of four gymnastic sports. The personal interviews were led my myself as well as preparing the query. Descriptive statistics are used to sort and analyzed the data obtained and the thesis illustrates the outcomes accordingly. The theoretical part has character of a summarizing study, which comes out of accessible materials research. The purpose is to collect pieces of information, subsequently organize them and interpret them by the form of recommendations in relation to flexibility development issue in gymnastics sports. Results: The results of the thesis are presented in a form of generally valid rules and recommendations in relation to the flexibility development issue overlapping to gymnastics sports. Such as showing how...

The main goal of this diploma thesis is to determine the role of hyaluron acid and phospholipids on friction and lubrication of articular cartilage in regard to optimization of viscosupplements. This is carried out by measuring the coefficient of friction of the articular cartilage with several lubricants. Cartilage is lubricated particularly by a conventional viscosuplement, optimized viscosuplementation with phospholipids and model synovial fluid. In order to observe the function of those viscosuplements in the human body, both are mixed with the model synovial fluid, ubiquitous in human joints, in given ratio. Experiments revealed high friction when it comes to convectional viscosupplementation as opposed to low friction of the optimized viscosuplement with phospholipids. The same situation occurs when cartilage is lubricated with those viscosuplements mixed with model synovial fluid which might lead to development of a new, better, viscosupplementation based on hyaluron acid and phospholipids.

Introduction The joint dysfunction of the spine in the sense of functional blockade is connected with corresponding painful condition, reflex contraction of the surrounding muscles and restriction of mobility in the spinal segment. Joint block has its mechanical context, which need not be accompanied by a structural disturbance but it's affecting the biomechanical properties of the spine. Several theories exist how the joints become restricted. Scientific evidence highly supports the meniscoid entrapment theory. Purposes The aim of the study was to identify the meniscoids of the cervical spine using in- vivo MRI imaging and to determine their potential role in the development of functional joint blocks of the axial system (AS). Another objective was to find out how the articular blocks affect the rheological properties of the spine by the Transfer Vibration through the Spine (TVS) method. Patient sample The MRI study was conducted on a research file of 12 subjects - two anatomical preparations and ten in vivo. Two subjects were examined in TVS experiment. Methodology Two anatomical preparations were investigated on MRI to find the appropriate sequence for imaging of meniscoids, three subjects for identification of meniscoids in vivo. Seven subjects underwent initial investigation, manipulation of...

Gaits is one of the most important factors affecting the quality of life and ability to self- care. This thesis assesses the effect of central movement control disorders to the walking abilities in youth patiens with cerebral palsy (CP). The theoretical part describes alterations of neuromotor system developmental and muscle characteristics in children with CP and explains the phenomenon of joint stiffness. Theoretical part also presents standardized functional tests to determine the severity of disability and provides information on increased energy intensity of walking in patients with CP. The practical part assesses the effect of central motor control disorders, muscle strength and energy expenditure of movement on the walking abilities in CP patients.
