Víšková, Anna ; Kračmar, Bronislav (advisor) ; Véle, František (referee)
Title: Kinesiologic analysis of function of selected upper limb muscles after female breast augmentation Objectives: The aim of this research is to analyze the functionality and scope of involvement of the injured muscles due to plastic surgical augmentation procedure at pre-selected physical activities before and after surgery a few months later (specifically, three months - the time the patient left the recovery) using a noninvasive surface electromyography (EMG). Methods: A Case Study measuring method of noninvasive surface electromyography in combination with the method of temporal phase shifts involved in the activation of muscle movement, accompanied by a support method of integrated EMG. Results: There differences have been observed in the timing of individual muscles measured during performing selected testing exercises before and after completion of the augmentation plastic surgery operatios. Furthermore, the possibility of the loss of muscle strength has been detected by some measured muscles and this has the potential to take over functions of damaged muscles. Key words: plastic surgery, female breast augmentation, surface electromyography, upper limb muscles, musculus pectoralis major

Discrimination of EMG signals from individual forearm muscles from surface EMG.
Krásná, Jana ; Otáhal, Jakub (advisor) ; Konopková, Renata (referee)
Title: Discrimination of EMG signals from individual forearm muscles from surface EMG Abstract: Location of electrodes for sensing the forearm muscles using surface electromyography is not accurately described. It is based only on recommendations by various authors in making researches. The aim of this study was to determine the optimal placement of electrodes on the forearm and describe it to another repeatable measurements. By analyzing the amplitude of EMG recording is confirmed not only the optimal location of electrodes, but either suggested muscle synergies that are possible to analyze more deeply in other studies because a detailed examination of muscle synergies are considerable application in upper limb prosthetics Keywords: Surface electromyography, forearm muscles, amplitude analysis

Effect of asymmetric load on the stereotype of running.
Holíková, Dana ; Pánek, David (advisor) ; Satrapová, Lenka (referee)
Title: Effect of asymmetric load on the stereotype of running. Objectives: The aim of this experimental work is to evaluace the electromyographic activity of selected muscles when running without load and with load on the treadmill, and the co- current assessment of the impact of asymmetric load on the lateral weight distribution. Methods: Six recreational runners underwent the experiment during which we monitored electrical activity of m. deltoideus pars anterior, m. trapezius pars ascendes et descendens, lumbar paraspinal muscles, m. gastrocnemius lateralis and m. tibialis anterior while running without load and with load on the periphery of the upper right extremity. For the experiment a motor treadmill at a constant speed of 10 km/h was used and a 0,5 l PET bottle completely filled with water was applied as the load. Changes of lateral weight distribution were assessed having investigated stance on two scales. The measured values were statistically evaluated. Results: Within the group of all the probands it was proved that there existed an impact on normalized average amplitude of EMG signal at left-oriented m. gastrocnemius lateralis. The hypothesis of the influence of asymmetric load on the lateral weight distribution was not demonstrated. Keywords: endurance running, surface...

Influence of horse breed and type of terrain on activation of the abdominal muscles in hippotherapy
Fraňková, Věra ; Lopot, František (advisor) ; Kubový, Petr (referee)
Title: Influence of horse breed and type of terrain on activation of the abdominal muscles in hippotherapy. Purposes: The aim of the study is to find out if horse breed and type of terrain approaches muscle activation in the position of unassisted sitting Methods: The study is of intraindividual character and incudes theoretical and practical part. The activation of abdominal muscles was measured by using surface electromyography and kinematic analysis. Results: There was differance between muscle activation with a different type of terrain. Horse breed does not influence a muscle activation but the individual biomechanic of each horse. Key words: hippotherapy, hipporehabilitation, horse breed, activation of abdominal muscles, unassisted seat, therapeutic horseback riding, electromyography

Muscle activity analysis during the violoncello play
Kasanová, Barbora ; Vilímek, Miloslav (advisor) ; Tlapáková, Eva (referee)
Title: Muscle activity analysis during the violoncello play Objectives: This thesis focuses on analysing and comparing specific back muscles of a bowing violoncellist. The findings can help understanding pathologic mechanisms and back pain caused by violoncello playing. It may be useful in choosing suitable preventive compensatory exercise as well and for future research. Eventually, the analysis could be applied in playing ergonomics and designing a proper seat. The thesis also aims on evaluating suitability of the chosen measuring method in this branch. Methods: The theoretical part reviews contemporary knowledge about musculoskeletal system disorders linked with violoncello playing. The practical part aims on evaluating data obtained from 3D kinematic analysis and surface EMG of specific back muscles of professional violoncello player during playing. Several conditions are assessed. Results: The experiment has shown that when playing a violoncello there is an asymmetric loading of the back muscles. Loading of specific muscles has is affected by way of bowing, string location and the seat. The experiment was done on a single proband, so these conclusions may not be generally valid. Keywords: violoncello playing, musicians, surface electromyography, 3d kinematic analysis, violoncellists' diseases,...

PNF technique after arthroscopic stabilization of the shoulder
Benešová, Martina ; Holubářová, Jiřina (advisor) ; Pavlů, Dagmar (referee)
Title: PNF technique after arthroscopic stabilization of the shoulder joint Objectives: The objective of this work is to consider the possibility of use of the proprioceptive neuromuscular facilitation technique (PNF) in early stages of rehabilitation after arthroscopic stabilization of the shoulder joint. The idea is to use the phenomen of irradiation with which this concept works. Methods: The pilot experimental group consisted of 7 healthy participants with simulated arthroscopic stabilization of the left shoulder joint. The electromyography was used to record the electric activity of musculus trapezius pars descendens, pars transversa et pars ascendens, musculus deltoideus pars acromialis, musculus infraspinatus and musculus pectoralis major pars sternocostalis on the immobilized left arm; while using the PNF technique on the peripheral parts of the immobilised arm; and on the contra lateral arm. A 5s sequence of stabilised isometric contraction was analysed and all data further normalised to Maximal Voluntary Contraction (MVC). Considering the literature the 20% increase above the MVC was defined as substantial to assure sufficient functional capacity of the muscle fibres and therefore sufficient to stop muscle atrophy during immobilisation of the arm. Results: Results of this study support...

Novotná, Petra ; Pánek, David (advisor) ; Jalovcová, Miroslava (referee)
Title: Effect of water temperature on the electrical activity of muscle Objective: Main objective of this work is to determine the spatiotemporal changes in muscle activation depending on different properties of the environment. All this at a defined muscle power output. Measured by hand dynamometer. Methods: This is a case study. Is processed and analyzed the relationship of the forearm muscles against the aquatic environment (different temperatures - 15 řC, 24 řC and 35 řC) and against dry. Muscular power output is defined and measured by hand dynamometer. Muscular power output was determined as isometric contraction flexors of wrist and fingers of dominant hand. It all in three different modes. The research group were included 5 healthy individuals (3 women, 2 men). As objectivization method was determined surface electromyography. Findings: There is no influence of water temperature (15 řC, 24 řC and 35 řC) on spatiotemporal activation of muscle. It all at a defined muscle power output. There is also no changes on spatiotemporal activation of muscle in aquatic and dry. Keywords: muscle contraction, temperature, water environment, surface electromyography, Water Surface EMG
