New studies on the knee joint function during load revealed differences in kinematics as compared with classical description of motion in the open chain. The difference appears to be due to the effects of breaking and elastic strengths. At the knee flexion after impact of the heel the femur condyles are shifted frontally along the tibia plateau. The medial condyle is shifted more so that flexion in the knee joint is associated with internal rotation of the shank or external rotation of the femur. Source

A questionnaire evaluating the intensity of food craving allows assessing the alimentary behaviour. Extreme eating patterns are typical of people with eating disorders; therefore the availability of suitable tools for measuring the intensity of food cravings could be an important factor for the diagnosis and determining of the appropriate treatment procedure for eating disorders. The aim of the study was to verify the specific and generic reliability of the Czech version of General-Food Craving Questionnaire-Trait (G-FCQ-T) which was translated into Czech by M. Svêtlák and M. Černík. A three-week interval of test and retest reliability was chosen, the same time as the authors of original questionnaire applied. The research sample consisted of 391 university students (157 men and 234 women) aged 18-21 years. The data analysis showed a very good internal consistency of the questionnaire, Cronbach's alpha was 0.93 for total score; and a good stability over time, the test-retest reliability was 0.82 after 3 weeks. Therefore, the Czech version of the questionnaire G-FCQ-T has a very good specific and generic reliability. The questionnaire is useful both for the research and the clinical practice in the Czech environment. Source

Aim: To analyze bone mineral density (BMD) in selected regions of the skeleton and evaluate the strength of its relationship to body composition in postmenopausal women. Methods: Ninety-seven women, aged 50-77 years, participated in this study. BMD and body composition were assessed by dual-energy x-ray absorptiometry (DXA). In addition to whole-body parameters, BMD of the lumbar spine, proximal femur and rib area was measured. Body composition was represented by body fat mass (BFM) and lean body mass (LBM) in the upper and lower limbs and trunk. Results: Significant association was observed between whole-body BMD and BFM (r = 0.41; p < 0.05) and LBM (r = 0.39; p < 0.05). BFM (r = 0.24; p < 0.05) of the trunk was a stronger predictor of lumbar BMD than LBM (r = 0.18; p > 0.05). Although the results of the statistical analysis showed a significant relationship between total and regional BMD of the proximal femur and LBM (r = 0.28-0.34; p < 0.05) of the lower limb, except for the Ward triangle (r = 0.16; p > 0.05), the correlation coefficient only ranged from 0.10 to 0.19 units for BFM (p > 0.05). However, the strongest associations were found between body composition and rib BMD, significantly correlating with BFM and LBM. Moreover, it was also shown that osteopenic women showed significantly lower LBM than women with normal BMD. The only exception was represented by LBM of the trunk which did not show significant differences. The differences in BFM were also statistically insignificant, except for BFM in the upper limbs. Conclusions: The results of this study showed the positive influence of body composition on bone health. Nevertheless, it is necessary to evaluate this association not only at the whole-body level, but also in selected body areas. Source

Objective: The aim of the study was to assess the effect of therapeutical horse riding on heart rate (HR) and subjective emotions (desire, tension) in novice riders. Participants: Twelve women (age 43 ± 11.6 years, weight 66.9 ± 11.6 kg, body height 163 ± 4 cm), without physical and mental disability, who did not have any horse riding experiences. Methods: The HR response to horse riding was measured by RS800CX system and then evaluated in Polar ProTrainer 5 software. The questionnaire using a modified Likert scale was used for the evaluation of personal feelings. The riding sessions were based on rules of hippotherapy (horse walking in step, riding without a seat). All participants underwent riding sessions with a duration of 20 minutes per day for 5 consecutive days. Results: The HR was significantly higher in the beginning of each riding session (p < 0.001) compared to its remaining part. The difference in subjective feelings was significant in the criteria of desire between the 1st and 5t session (p < 0.01), when the values were significantly higher before the last session. The tension before the 1st session was significantly higher (p < 0.01) than before the other four session. Source

PURPOSE OF THE STUDY Repeated measurements of the spine are absolutely necessary in children and adolescents affected by spinal deformities especially during their growing-up periods. To avoid risks of tissue damage from x-ray exposure, several methods for non-invasive measurement of the spinal curvature have been developed. One of them is the DTP-3 position system allowing for a three-dimensional measurement of anatomical landmarks (spinous processes) and the calculation of curvature angles in both the frontal and sagittal planes. We were interested to know whether the DTP-3 was precise enough to determine the true spinal curvature. MATERIAL AND METHODS To determine the precision of the DTP-3 system, we constructed amodel of the spine. The model was then repeatedly investigated by both the noninvasive and x-ray methods. The distortion of x-ray images caused by the central projection mechanism was considered and included in the calculation. In addition, a group of patients with scoliosis up to 40° was evaluated by both the DTP-3 system and x-ray (the latter according to Cobb's method). RESULTS Differences in spatial coordinates between DTP-3 and x-ray examinations reached 20.9 mm in the frontal plane and 67.3 mm in the sagittal plane without distortion correction of x-ray images. The differences decreased below 1.5 mm after image distortion correction in each plane. Distortion correction had not the same effect for angle parameters as for coordinates. Differences between the DTP-3 angle parameters and Cobb's x-ray angles were below 4.7°, both without correction and after correction. The difference between DTP-3 angle parameters and Cobb's x-ray angles was-1.8°? 3.0° (mean? standard deviation) when measurement was performed on the patients with scoliosis. DISCUSSION The goal of any clinical examination is to obtain data applicable to decision-making analysis. In the case of scoliosis it is necessary to report results in terms of Cobb's angle, which is the problem for all surface-dependent methods, especially in patients with double curves. A solution may be to define the maximal difference between noninvasive and x-ray methods that could be acceptable for good clinical practice. CONCLUSIONS In this study we report good concordance between noninvasive and x-ray examinations of a modeled spinal deformity in terms of both angle and linear measurements. The same results were obtained for angle measurements in a group of patients with scoliosis up to 40°. Based on this study and our previous data we believe that the DTP-3 system can be introduced into clinical practice. © Česká společnost pro ortopedii a traumatologii 2006. Source
