Background: and study aim: Each sports activity, particularly combat sports, involves various injuries and overloads. Injuries are a result of impact of sudden large for ceson tissues, while overloads are caused by small but repetitive forces, which lead to some dysfunction, pain. The aim of this study was to compare injuries and overloads in two combat sports, namely judo and Thai boxing. Material and methods: The study was conducted on 34 judokas (from MaKo Judo Wrocław Sports Club) and 34 Thai boxers (from Puncher Wrocław Sports Club). The group of Thai boxers consisted of 29 men and 5 women, where as the judoka group was comprised of 23 men and 11 women. The average age of participants was 22.6 years. Internship competes patients was 3 years. The training period was similar for Thai boxers and judokas: Thai boxers trained on average for 8.5hper week, while judokas trained for 6.9h per week. Results: The study demonstrated that the most common injuries in Thai boxers occurred in lower limbs, while in judokas– in shoulder joints, knee joints and the spine. Thai boxers most frequently developed overloads in lower limbs, whereas judokas– in shoulder joints and the spine. Conclusions: Thai boxers considerably more frequently sustained injuries of feet, elbow joints and thighs, compared to judokas, who sustained more knee joint injuries. Judokas considerably more frequently suffered from injuries of shoulder joints and the spine compared to Thai boxers. Thai boxers more often developed overloads of lower limbs and elbow joints compared to judokas. On the other hand, judokas considerably more frequently sustained overloads of the spine and shoulder joints compared to Thai boxers.

Abstract : Transfemoral Amputasi, Transfemoral Prosthesis, Polycentric Knee Joint. World Health Organization (WHO) estimated that there are 40 million amputees throughout the developing countries. Amputation in the lower limbs reached 85% -90% of all amputations. Transfemoral amputation because of this amputation occurs in the thigh that passed through the femur bone. Amputation causes significant gait abnormalities. amputation levels increased, the functional level is reduced, and the characteristic of the gait abnormality is immediately apparent. Transfemoral Prosthesis is artificial limb that made for above knee amputation. making process of transfemoral prosthesis includes assessment, measurement, casting, fabrication, fitting, finishing. Of all components for transfemoral patients, prosthetic knee joints are the most important components that can affect to gait stability. The choice for the type of popular passive knee mechanism is polycentric knee. The polycentric knee joint mechanism, linkage of 4 and 6 bar mechanisms have been used to increase stability during the stance and kinematic phase of the swing phase.

AbstractAim of the study: The aim of this study was to evaluate how sports activity influences the extent and incidence of muscle shortening in lower limbs in physically active and inactive young women. Material and methods: A group of 30 pupils aged between 14-16 was tested. Fifteen pupils out of the group regularly played volleyball in TRS Siła Ustroń sports club, while the remaining fifteen were physically inactive. The Functional Movement Screen (FMS) system was used to assess the level of motor ability, and four functional tests were used to measure the length of lower limbs muscles based on the use of V-Rippstein plurimeter. In addition to tests the students also filled out a questionnaire. Results: The results of the analysis showed that among the physically inactive pupils the muscle shortening occurred more frequently in comparison to the students who played volleyball. Moreover, the results of the FMS indicated that the young women who took up sports had a higher level of motor ability than their peers. Conclusions: Regular physical activity improves and maintains normal length of muscles of lower limbs.

Data Set

Background: Osteoarthritis (OA) is a degenerative disease of joint cartilage affecting the elderly people around the world. Visualization and quantification of cartilage is very much essential for the assessment of OA and rehabilitation of the affected people. Magnetic Resonance Imaging (MRI) is the most widely used imaging modality in the treatment of knee joint diseases. But there are many challenges in proper visualization and quantification of articular cartilage using MRI. Volume rendering and 3D visualization can provide an overview of anatomy and disease condition of knee joint. In this work, cartilage is segmented from knee joint MRI, visualized in 3D using Volume of Interest (VOI) approach. Methods: Visualization of cartilage helps in the assessment of cartilage degradation in diseased knee joints. Cartilage thickness and volume were quantified using image processing techniques in OA affected knee joints. Statistical analysis is carried out on processed data set consisting of 110 of knee joints which include male (56) and female (54) of normal (22) and different stages of OA (88). The differences in thickness and volume of cartilage were observed in cartilage in groups based on age, gender and BMI in normal and progressive OA knee joints. Results: The results show that size and volume of cartilage are found to be significantly low in OA as compared to normal knee joints. The cartilage thickness and volume is significantly low for people with age 50 years and above and Body Mass Index (BMI) equal and greater than 25. Cartilage volume correlates with the progression of the disease and can be used for the evaluation of the response to therapies. Conclusion: The developed methods can be used as helping tool in the assessment of cartilage degradation in OA affected knee joint patients and treatment planning.

This article studies the effects of arthroscopic imaging treatment and clinical rehabilitation of knee sports injuries. Arthroscopy was used to perform meniscus trimming and resection for 40 patients with knee sports injuries. The ages of the patients ranged from 20 to 60 years old. All patients received routine rehabilitation training such as continuous passive motion of the knee joint, biofeedback of the lower limbs, and air pressure therapy of the lower limbs. In addition, the control group was given muscle strength training, and the training began after the patients received the quadriceps muscle strength test. The removal of the joint cavity and the joint debridement has achieved satisfactory treatment results. In the experiment, the test cases were divided into two groups, and the sensor test platform was used for signal collection. Normal activities can be resumed 2 weeks after the operation. After a follow-up of 6 to 24 months, the knee joint pain disappeared, the joint was free of swelling, and the knee function was normal up to 93%. Arthroscopic reconstruction of the anterior and posterior cruciate ligament joint repair/reconstruction of the medial and posterolateral ligament knots is safe and feasible for the treatment of multiple ligament injuries of the knee joint. It has the advantages of less trauma and quick recovery. Early postoperative systemic and standardized rehabilitation exercises can obtain good knee joint function.

1. The present study addresses the involvement of voltage-dependent calcium channels of the N and L type in the spinal processing of innocuous and noxious input from the knee joint, both under normal conditions and under inflammatory conditions in which spinal cord neurons become hyperexcitable. In 30 anesthetized rats, extracellular recordings were performed from single dorsal horn neurons in segments 1–4 of the lumbar spinal cord. All neurons had receptive fields in the ipsilateral knee joint. In 22 rats, an inflammation was induced in the ipsilateral knee joint by kaolin and carrageenan 4–16 h before the recordings. The antagonist at N-type calcium channels, omega-conotoxin GVIA (omega-CTx GVIA), was administered topically in solution to the dorsal surface of the spinal cord at the appropriate spinal segments in 6 rats with normal joints and in 12 rats with inflamed knee joints. The antagonist at L-type channels, nimodipine, was administered topically in 5 rats with normal joints and in 11 rats with inflamed knee joints. In another five rats with inflamed joints, antagonists at L-type calcium channels (diltiazem and nimodipine) and omega-CTx GVIA were administered ionophoretically with multibarrel electrodes close to the neurons recorded. 2. The topical administration of omega-CTx GVIA to the spinal cord reduced the responses to both innocuous and noxious pressure applied to the knee joint in a sample of 11 neurons with input from the normal joint and in a sample of 16 neurons with input from the inflamed joint (hyperexcitable neurons). The responses were decreased to approximately 65% of the predrug values within administration times of 30 min. A similar reduction of the responses to innocuous and noxious pressure was observed when omega-CTx GVIA was administered ionophoretically to nine hyperexcitable neurons. In neurons with input from the normal or the inflamed knee joint, the administration of omega-CTx GVIA led also to a reduction of the responses to innocuous and noxious pressure applied to the noninflamed ankle joint. 3. The topical administration of nimodipine decreased the responses to innocuous and noxious pressure applied to the knee in a sample of 9 neurons with input from the normal joint and in a sample of 16 neurons with input from the inflamed knee joint (hyperexcitable neurons). Within administration times of 30 min, the responses were reduced to approximately 70% of the predrug values. In hyperexcitable neurons, the responses to innocuous and noxious pressure applied to the knee were also decreased during ionophoretic administration of nimodipine (6 neurons) and diltiazem (9 neurons). When the noninflamed ankle was stimulated, the responses to innocuous pressure were reduced neither in neurons with input from the normal knee nor in neurons with input from the inflamed knee, but the responses of hyperexcitable neurons to noxious pressure onto the ankle were reduced. The ionophoretic administration of the agonist at the L-type calcium channel, S(-)-Bay K 8644, enhanced the responses to mechanical stimulation of the knee joint in all 14 hyperexcitable neurons tested. The effect of S(-)-Bay K 8644 was counteracted by both diltiazem (in 6 of 6 neurons) and nimodipine (in 5 of 5 neurons). 4. These data show that antagonists at both the N- and the L-type voltage-dependent calcium channels influence the spinal processing of input from the knee joint. The data suggest, therefore, that voltage-dependent calcium calcium channels of both the N and the L type are important for the sensory functions of the spinal cord. They are involved in the spinal processing of nonnociceptive as well as nociceptive mechanosensory input from the joint, both under normal and inflammatory conditions. The present results show in particular that N- and L-type channels are likely to be involved in the generation of pain evoked by noxious mechanical stimulation in normal tissue as well as in the mechanical hyperalgesia that is usually pres

The design of a knee joint is a key issue in robotics and biomechanics to improve the compatibility between prosthesis and human movements and to improve the bipedal robot performances. We propose a novel design for the knee joint of a planar bipedal robot, based on a four-bar linkage. The dynamic model of the planar bipedal robot is calculated. We design walking reference trajectories with double support phases, single supports with a flat contact of the foot in the ground and single support phases with rotation of the foot around the toe. During the double support phase, both feet rotate. This phase is ended by an impact on the ground of the toe of one foot, the other foot taking off. The single support phase is ended by an impact of the swing foot heel, the other foot keeping contact with the ground through its toe. For both gaits, the reference trajectories of the rotational joints are prescribed by polynomial functions in time. A parametric optimization problem is presented for the determination of the parameters corresponding to the optimal cyclic walking gaits. The main contribution of this paper is the design of a dynamical stable walking gait with double support phases with feet rotation, impacts and single support phases for this novel bipedal robot.

The paper analyzes the effectiveness of magnetic resonance imaging with cartilage diagram in diagnosing signs of professional deforming arthrosis of knee joints in miners working in conditions of significant physical loading. Aim of the research – to determine of diagnostic efficiency of indicators of magnetic resonance imaging of the knee joint and cartilage diagram in miners of the main occupations suffering from deforming arthrosis. Methods. The research is conducted in 30 miners of basic occupations: 20 mining workers of breakage face (MWBF) and 10 machinists of shearer mining machines (МSMM) have been treated in the inpatient department of occupational pathology of the Lviv Regional Clinical Hospital in 2015-2017 due to deforming arthrosis. Damages of the main anatomical elements of the knee joint with arthrosis were analyzed, visualized initially with the help of MRI, and then - cartilage diagram. Results. According to the MRI data, in miners of the main occupations with arthrosis of the knee joint the posterior cross-shaped ligament are most commonly affected (in 75.0±9.7 % MWBF and 70.0±14.5 % МSMM), damage to the medial collateral ligament are diagnosed less frequently (in 5.0±4.9 % in the MWBF and in 10.0±9.5 % in the МSMM). On average 3.8±0.4 modified elements of the knee joint are visualized in patients, whereas 4.8±0.1 affected areas are visualized on the cartilage diagram (р<0.05). In 86.7±6.2 % patients, in the analysis of cartilage diagram, changes in all five analyzed areas are diagnosed, indicating a higher efficiency of the diagnosis of changes in the structures of the joint with DA of the professional etiology of the method of cartilage diagram compared with MRI. According to the cartilage diagram the most significant changes are noted in the hypertrophy of the femur: among all miners 62.5±0.3 ms (medial) and 62.6±0.4 ms (lateral), in the MWBF group the average time of Т2-delay is the largest in the area of the medial hypertrophy of the femur is 60.9±2.3 ms, in the МSMM group – in the area of the lateral hypertrophy of the femur: 66.7±3.3 ms, which can be linked to the peculiarities of the forced working position of miners of these professions and the kinetics of joint structures. These results can be used to diagnose the initial lesions of joint structures with DA of professional genesis, as well as the creation of prognostic models for determining the the degree of risk of development of knee joint damage, which will allow to improve the system of personified approach to diagnostic and preventive measures in working persons in conditions of considerable physical activity and forced working position.

Rehabilitation Intervention

Excessive training loads during sports cause chronic functional overload of the joints and their trauma, which reduces the quality of life of athletes, limits activity and participation, termination of sports careers, and in severe cases - disability. In sports practice, one of the most common sites of osteoarthritis is the knee joints (gonarthrosis). Gonarthrosis of the knee joint is a degenerative-dystrophic disease in which the destruction of hyaline cartilage, deformation of bone tissue and the qualitative composition of synovial fluid. A key link in the development of an individual program of rehabilitation intervention is the formulation of a rehabilitation diagnosis. The aim of the research: to determine the rehabilitation diagnosis of patients with gonarthrosis of the knee joints on the basis of the International Classification of Functioning, Restriction of Life and Health (ICF). Materials and methods: theoretical (analysis and generalization of scientific-methodical and clinical literature); clinical (analysis of medical records, communication, palpation, clinical and functional testing; physical examination); scale methods for assessing the condition of patients (Leken index, pain scale, depression scale (CES-D), assessment of quality of life according to the SF-36 questionnaire); instrumental (goniometry, manual-muscular testing). The research involved 7 veteran athletes aged 45 to 49 years with primary gonarthrosis stage II. Inclusion criteria: current athletes - men of different specializations; primary gonarthrosis of the second radiological stage according to Kellgren; duration of pain not less than 4 months; the level of pain when walking on the scale of YOUR 45 and more; age of patients older than 45 years; informational consent of patients to participate in the research. Inclusion criteria: secondary gonarthrosis of the knee joint; the presence of comorbidities; severe condition of the patient; knee surgery; planning of arthroplasty of the knee joint; intra-articular injections; lack of information consent. Rehabilitation diagnosis is the most complete reflection of the patient's current problems, which affect the level of his functioning, activity and participation, and are significant for him. It is established by all members of the multidisciplinary team, and is based on the results of comprehensive rehabilitation diagnostics. The main tool for establishing a rehabilitation diagnosis are the categories and domains of IFF. Rehabilitation diagnosis of patients with gonarthrosis: moderate structural changes in the knee joints (s750.2), episodic moderate pain (b28014.2), short-term morning stiffness (b7800.2), decreased mobility of the knee joint (b710.2), his stability (b7150.2) and support function, decrease in muscle tone (b7350.2) and strength of the quadriceps femoris (b7300.2), which limits domestic activity and prolongs it over time (d450.1); difficulties in changing body position (d410.2), moving up stairs and moving long distances (d460.3), which limits participation in active forms of recreation. Patients report poor mood, depression due to health and forced restriction of participation (b152. 1), and concerns about future careers. Conclusions. Rehabilitation care is provided to patients in several stages, one of which is the formulation of a rehabilitation diagnosis. Rehabilitation diagnosis was established, in which the current problems of patients at the level of structure and function, activity and participation, as well as contextual factors that contribute, limit or prevent the achievement of the desired level of functional independence, allow individualization of rehabilitation intervention to bring this level to the maximum possible.
