Title: Relationship between hand grip strength and cognitive function in older adults over 65 years of age Goals: The main goal of this diploma thesis was to find out possible links between hand grip strength and cognitive functions in older adults over 65 years of age Method: As part of the master's thesis, a secondary analysis of data from the international cross- sectional study conducted within the Survey of Health Ageing and Retirement in Europe (SHARE) project was performed. The participants of the study were divided into seven categories based on their educational attainment, separately for both men and women. Generalized linear models were calculated for each of the mentioned categories as part of the data analysis. Results: The survey included a total of 38,519 participants with an average age of 74.00 ± 6.7 years from 18 countries worldwide. More than half of the participants were women. In the data analysis, it was found that the most represented educational group among the participants was the third group with higher secondary education, as defined by the ISCED 2011 classification. The tables indicate that values of all percentiles increase linearly with higher levels of education. This result suggests that higher education is associated with better performance in the examined test....

Dynamometric measurements for 11-year-old boys
MOLNÁR, Matěj
The aim of the bachelor's thesis is to assess the results of measurements with three devices evaluating the strength of the muscles of the upper limb (Collin, Takei and the Vernier school system). The group of probands consisted of 37 boys aged 11 years from the Vysočina region. In addition to muscle strength, somatic dimensions such as body height, body weight and skin fold over the triceps were also measured. Compared to the norm for the Czech population (VI. Natiowide Anthropological Survey 2001), the average values of body height (p = 0.01) differ statistically significantly in favor of our group, the values of body weight (p = 0.95), Body Mass index (p = 0.11) and skin fold over the triceps (p = 0.58) did not differ statistically significantly. The student's t-test revealed statistically significant differences between the mean values of the group in the measurements of the Takei, Vernier and Collin instruments in favor of the Takei dynamometer. Correlation analysis showed that the values of hand grip strength between Takei-Vernier (p = 0.00) and Takei-Collin (p = 0.00) correlated statistically significantly. However, for Takei and Vernier (first measurement, right hand, r = 0.81) correlated more closely than with the Takei and Collin instruments (first measurement, right hand, r = 0.51).

Sarcopenia in patients with Huntington's disease
Šoltésová, Mária ; Klempíř, Jiří (advisor) ; Růžičková, Lucie (referee)
Introduction: This cross-sectional, non-interventional, non-randomized, prospective and observational study aims to determine whether sarcopenia and its types occur in a cohort of 16 patients with Huntington's disease and, if so, at which stages of the disease. The study also aspives to identify patients with Huntington's disease who are at risk of sarcopenia (so-called presarcopenia). In addition, the study also compares the results of nutritional and functional status tests between a group of patients and healthy controls who were of the same sex, age and with no further acute or chronic disease that could significantly affect their nutritional and functional status. This was done to determine to what extent the patients exhibit reduced nutritional and functional parameters as compared with the healthy population. Methods: Individuals with clinically diagnosed Huntington's disease who agreed to participate were recruited. These individuals are outpatients of the Department of Neurology, VFN in Prague and the 1st Faculty of Medicine, Charles University in Prague. A series of tests were performed to assess the nutritional and functional status of the individual - questionnaires of functional status, self-sufficiency and sarcopenia, bioimpedance testing, strength tests using a hand dynamometer and...

Isokinetic strength of shoulder rotation in elite Czech female volleyball players
Hoppeová, Andrea ; Šteffl, Michal (advisor) ; Vorálek, Rostislav (referee)
Title: Isokinetic strength of shoulder rotation in elite Czech female volleyball players Objectives: The main goal was to evaluate and compare the results of measuring internal and external rotation in the shoulder joint of elite volleyball players of the age categories "Women" and "Juniors U18". Method: The players of the national teams "Juniors U18" and "Women" took part in the measurement. Isokinetic strength parameters were measured using a Cybex Humac Norm isokinetic dynamometer (Cybex NORM®, Humac, CA, USA). The maximum strength of internal and external rotation of the shoulder joint was evaluated. Muscle strength was measured at an angular velocity of 60 ř/s and the upper limb was abducted at 90ř. Descriptive statistics on the test result were calculated and evaluated using the Excel software (Microsoft, USA). Statistical data processing was performed at the level of comparison of averages and percentage differences between individual categories of results. Results: The results show that the Women group had higher strength than the U18 Junior group. On the contrary, the U18 Junior group had more balanced results, both between the dominant and non-dominant limb and between internal and external rotation. The measured strength of rotation in Women shown a greater muscle imbalance. In...

Kinesio taping in treatment and prevention of thumb overload in outpatient physiotherapy
Neklanová, Anna ; Ravnik, David (advisor) ; Tlapáková, Eva (referee)
Title : Kinesio taping in treatment and prevention of thumb overload in outpatient physiotherapy Purposes : The main purpose of this thesis was to evaluate a degree of pain decrease in thumb joint after kinesio tape application. The differences in grip strength were concurrently evaluated to objectify previous results. Hand dynamometer was used to support this claim. Methods : Data for the experiment were obtained by use of hand dynamometer measurement and record of a pain degree according to chosen pain scale. Each person was measured right before defined strain and immediately after it (daily work in outpatient therapy according to therapist's working shift). Each therapist was asked to record a degree of actual pain following the instructions during strain. All the results were processed and statistically analyzed. Results : The results show that kinesio tape is successful in decreasing of thumb joint pain. This was confirmed both during and after the strain. At the same time kinesio tape prevents decreasing of the grip strength. Keywords : Thumb, thumb joint, kinesio taping of a thumb, dynamometry, pain decrease of a thumb, overloading of a thumb
