The purpose of this thesis is to design an innovative sickbed for the paralyzed patients. One goal of the sickbed is to avoid the occurrence of pressure ulcers. The other one is to tune the tensions of patient¡¦s muscles. To analyze the muscle tension, a simplified model for human body was proposed. This model divided the human body into 5 blocks when ignoring the arms and hands. It described the geometric relationships between the blocks and muscles under different body postures and external supports from the design sickbed. It was noted that the number of unknowns of the model was larger than the number of equations derived from the equilibrium conditions. An optimization method, which was to obtain a desired distribution of muscle tensions, was adopted to find the solutions for the unknowns. Among the possible supporting states, which included the body postures and supporting locations, the ones that met the desired tension distribution were searched. Then, the technique of Graph theory was used to obtain a set of supporting states that could avoid the occurrence of pressure ulcers. Finally, a preliminary design of the sickbed structure was discussed. If the relaxed condition of muscles was desired, the simulation study indicated that large number of supporting states could meet the purpose. That means there exist many body postures or supporting locations allowing the muscles of body in the relaxed condition. This feature allows one to choose a set of supporting states that two consecutive states own different supporting locations and prevents any spot of body from continuous loading. Such a supporting scheme should minimize the occurrence of pressure ulcers.

Title The influence of muscle tonus with hormonal contraception Objective The thesis aims to determine whether and to what extent the use of hormonal contraception affects muscle tension, which can vary depending on the current phase of the menstrual cycle in women. Method The thesis is divided into theoretical part where there is a summary of information on this topic from the literature Czech and world, a special part that is treated as research using noninvasive myotonometer. The measurement is performed in 12 probands four times in four weeks, always at some stage of their menstrual cycle. The measurement results are compared between the two groups by probands and is found to influence hormonal contraceptives on muscle tension during the menstrual cycle. Results Measurement myotonometer shows that hormonal contraceptive use affects muscle tension. The measurement results show a stable and predictable changes in fluctuating muscle tension in probands who use hormonal contraceptives, but the rate changes are subject to interpersonal differences, and these results can not give a general opinion. Key words Menstrual cycle, hormonal contraception, muscle tension, myotonometer

Title: Effect of passive stretching on current patient's mental state Objectives: This thesis presents a pilot theoretical - empirical experiment, where the main subject of the experiment is to evaluate the effect of passive stretching hypertonic or shortened muscles, i.e. decreased muscle tone on current patient's mental state. The theoretical part summarizes the neurophysiologic basis of emotions by search form. Through the implementation and follow-up experiment, we aim to demonstrate the positive impact of stretching exercise on current psychological state. Methods: Two groups of patients participated in this research, thirty without pain and thirty with pain. We chose questionnaire PANAS-X (Watson, Clark, 1994) to diagnose their current mental state. The first group, patients without pain, completed the questionnaire before and immediately after the experimental intervention, i.e. passive stretching hypertonic muscles. The second group, patients with pain, went through stretching exercise unit twice a week for three weeks. As for this group, we compare the situation before the first therapy with the state after six sessions. We evaluated the change in the individual sublevels of positive and negative emotions by the methodology of the questionnaire. Results: During the experiment three out of...

Syftet var att undersöka om exponering inför emotionella röster påverkar muskelanspänning och hjärtats slagfrekvens samt om det finns en samvariation mellan storlek eller längd på muskelanspänning vid aversiv emotionell input och grad av alexitymi. 24 studenter lyssnade på arga, glada och neutrala röster samtidigt som muskelanspänning mättes med EMG och hjärtats slagfrekvens med EKG. Grad av alexitymi mättes med Toronto Alexithymia Scale 20. Resultaten visade att arg eller glad röststimuli gav större muskelanspänningen än neutralröststimuli. Ingen skillnad i muskelanspänning fanns mellan arg eller glad röst. Det fanns inget samband mellan storlek eller längd på muskelanspänning och grad av alexitymi. / The object was to investigate whether exposure to emotionally valid voices, affect muscle tension and heart rate, and if there is a correlation between size or length of muscle tension during aversive emotional input and degree of Alexithymia. 24 students listened to angry, happy and neutral voices while muscle tension was measured by EMG and heart rate by EKG. Degree of Alexithymia was measured by Toronto Alexithymia Scale 20. The results showed that angry or happy voice stimuli caused higher muscle tension than neutral voice stimuli. No difference in muscle tension was shown between angry and happy voice. There was no correlation between size or length of muscle tension and degree of Alexithymia.

Title: The effect of foam roller on muscle tone after physical load Objectives: The aim of this thesis was to summarize theoretical knowledge about muscle, changes in muscle tension and possibilities of its affect. The aim of the practical part was to find out the effect of the foam roller on muscle tone after exercise. Methods: Practical part of this thesis was processed in biomechanical laboratory at FTVS UK in Prague and included 16 probands. We measured muscle tone of biceps brachii, m. triceps surae and m. quadriceps femoris before exercise, then the probands performed an activity aimed at increasing the muscular tension of the musculature mentioned above, after which we measured the muscle tension again. The foam rolling of each muscle group lasted for 60 seconds and then we measured the muscle tone for the last time. A myotonometer device was used and the data were transmitted by KISTLER MULTICHANNEL CHARGE AMPLIFIER and processed by the DeweSoftX3 (64 bit) programme in SIRIUS DEWEsoft S-BOX2 computer. At the end, we compared measured values with subjective sensations of the probands who filled quick questionnaire. Results: The measurement showed that after exercise, the muscular tensions of the muscle groups we selected increased, and at the same time that the application of the foam roller...

Title: Effect of sauna on muscle tone after physical excersise Topic definition: This thesis presents a pilot theoretical - empirical two-factor experiment, where the main subject of the experiment is to evaluate the effect of sauna on increased muscle tension after sport and its potential for use in physical therapy and recovery. Aim of the thesis: To provide a summary of theoretical knowledge related to the subject and to assess the impact of sauna usage on muscle tension occurred after short term maximal anaerobic excercise and compare it with passive rest. Methods: This thesis will be processed at the Faculty of Physical Education and Sport on 6 individuals, who will be randomly divided into two equally large groups. The first three-person group will be a research one, the second three-member group will be the control group. Afterwards they will be subjected to a Wingate stress test. The experimental group will participate in sauna treatments and the control group in passive rest. Muscle tension will be measured before the load, after the load, and after the sauna / passive rest. Measurements will take place in a kinesiology lab at the Faculty of Physical Education and Sports. Measurements will be done by using a myotonometer and the data will be gathered via an analogue-digital converter and...

Title: The effect of manual lymphatic drainage on the musculus soleus muscle tension in patients with chronic venous insufficiency. Aims: The aim of this thesis is to summarize theoretical knowledge about chronic venous insufficiency, muscle tension and manual lymphatic drainage and then to perform a pilot study to determine whether people suffering from chronic venous insufficiency have changed muscle tone of musculus soleus and to verify whether the implementation of a single manual lymphatic drainage of the lower limbs results in a change of muscle tension of musculus soleus. Methods: There were three patients who participated in the experiment. Anthropometric examinations of circuits of both lower limbs on all patients was carried out, using measuring tape and then a muscle tone of musculus soleus was measured using a device called myotonometer. After that the single manual lymphatic drainage of one lower limb (more affected lower extremity) was performed. The second, untreated leg was considered to be the control limb. There was also performed basal treatment of the neck, before every manual lymphatic drainage of lower limb. Circumferential dimensions of both lower limbs were measured immediately after manual lymphatic drainage and then 15 minutes later again. After that the muscle tone of...
