Title Cervicogenic headache Objectives It focuses on the prevalence of this disease in the general population and on the cervical spine segment where the dysfunction in patients with cervical headache occurs the most frequently. It also focuses on the effectiveness of manipulative therapies for this diagnosis. Method The thesis is conceived as a scientific literature research. In order to obtain sources professio- nal database such as Pubmed, PEDro, Medline, HighWire, Science direct were used. The thesis is divided into a theoretical and an analytical part. There have been 3 research questions set for the purposes of the thesis. Results Based on the analysis of available studies, the thesis confirmed that the incidence of cervico- genic headache in the general population is not negligible. It has been proved that the diagno- sis is quite frequent in patients suffering from headache, which may represent up to 35 % of patients. The results of available studies indicate that the dysfunction of the cervical spine causes 15-20 % of cervicogenic headaches. In most of the cases, it is the influence of the C1- C2, which is in more than 60 % of the cases. On the other hand, the influence of the AO joint is not very frequent. It only occurs in approximately 7 % of the cases. Due to the fact that the...

Obyt, Daniel ; Šifta, Petr (advisor) ; Nováková, Pavlína (referee)
Title: The influence of skating frequency on muscle tone of musculus triceps surae. Objective: The aim of this master degree thesis is to determine whether and how much influence the frequency and intensity of isotonic load the muscle tone of musculus soleus during skating of a professional ice hockey player. The muscle tone of musculus soleus is the most objectively measured part of musculus triceps surae by myotonometer. Summary: The master degree thesis is divided into the theoretical part, the processed form of research that serves as a basis for investigation in the second, empirical part. Change in muscle tone of musculus soleus will be investigated by using myotonometer, which will follow after a full physiotherapy examination. Measurements will be performed on 10 subjects - professional ice hockey players who are fully manage the technique of skating on the ice, before load, after low frequency isotonic load and after high frequency isotonic load. Conclusion: The myotonometric measurements revealed that after low and high frequency isotonic load of skating on ice rink, the muscle tone of musculus soleus is the same or slightly lower than before load. Keywords: Muscle tone, myotonometer, musculus soleus, skating, ice hockey

Stránský, Vojtěch ; Šifta, Petr (advisor) ; Otáhal, Jakub (referee)
Title: Influence of crank arm length on change of muscle tone of musculus triceps surae Objectives: The aim of this thesis is to conclude the theoretical knowledge of this issue. The experiment is to uncover via the objective results, if the change of the crank arm length can influence the muscle tone of m.triceps surae and additionaly how much. Methods: The measurement for this thesis was processed at Charles University at the Faculty of Physical Activity and Sports, measuring 8 volunteers. Via myotonometry, the biomechanic properties (stiffness and viscosity) of m.triceps surae were measured before and after the workout on a bicycle ergometer. These steps were repeated twice within a week with different crank arm length (170mm and 175mm). On the basis of the reaction of soft tissues on deformation from the tip of the myotonometer, the graphs are depicted, containing the hysteresis curve. We evaluate there two phenomenons - steepness and the content of the curves. They indicate biomechanic properties of soft tissues, resp. also the muscle tissue. Results: The measurements from the 1st and 2nd week were compared. The results of 8 probands show that cycling as a physical activity changes stiffness and viscosity of m. triceps surae and has therefore an influence on the muscle tone. Considering larger...

Author: Bc. Michaela Richtrová Tittle: Golf swing in subjects with amputation of lower extremity Objectives: The study aims at evaluation of the technique of golf swing used by patients with a different type and level of lower extremity amputation as compared to able-bodied golfers. Another objective is determination of the relation between individual phases of the golf swing and weight transfer, using different golf clubs, as compared to able-bodied golfers. Method: By its topic the work is a pilot study. The research has been divided into three descriptive case studies. The experimental group included two amateur golfers and one professional golfer. The control group was represented by an able-bodied golfer. Evaluation of kinematic parameters (trajectory of shoulders, hips, knee joints) was based on the Qualysis Motion Capture System. Evaluation of dynamic parameters (weight transfer) in the course of golf swing was made using two dynamometric Kistler platforms. Results: The measuring has demonstrated that in terms of both kinematics and dynamics, the mode of movement of a patient with a trans-tibial amputation during a golf swing corresponds to that of an able-bodied golfer. The same results were achieved by the patient also with the use of another type of golf club. A change, both in terms of...
