Electromyographic Analysis of the Different Handlebars Grips Effect on the Shoulder Blade Fixators
Hrdlička, Vít ; Pánek, David (advisor) ; Pavlů, Dagmar (referee)
Title: Electromyographic Analysis of the Different Handlebars Grips Effect on the Shoulder Blade Fixators Aims: The main objective of this thesis is to carry out a methodological study on the impact of different handlebars grips on the shoulder blades fixators. Result of the grip change is not only reduction of the upper fixators activity and the increase in the lower fixators activity but also co-contraction index increase and muscle fatigue reduction. Based on the hypothesis we assumed that the highest activity rate of the lower blades fixators and the lowest activity rate of the upper blades fixators will be during the handlebars brakes grip. The highest co- contraction index will occur during the handlebar brakes grip and the maximum muscular fatigue will occur during the grip at the top of the handlebars. The first part of the thesis is focused on the literature search and facts retrieval pertaining to the studied issue. In the second special part of the thesis we conducted a research during which the muscle activity of the upper and lower blade fixators was recorded. Three different handlebars grips were considered during the measurement using the cycle ergometer. Methods: Muscle activity was scanned and recorded using surface EMG. Maximal voluntary contraction of selected muscles based on...

Sanni, Modinat ; Vilímek, Miloslav (advisor) ; Šifta, Petr (referee)
Author: Bc. Modinat Sanni Supervisor: Ing. Miroslav Vilímek, PhD Title: MUSCLES ACTIVATION DURING "SHOULDER MOUNT"POLE ACROBATIC EXERCISE Purpose: This study is an empirical - theoretical study presents the literature review regarding to the topic of the shoulder function anatomy, kinesiology, biomechanics, non-traumatic injuries of the shoulder and their prevention by using the available literatures. Further, the study also compares by surface electromyography the amplitudes, shapes and durations of myoelectric signals of m. latissimus dorsi, m. pectoralis maior, m. biceps brachii, m. infraspinatus and m. supraspinatus of dominant shoulder in two healthy individuals during acrobatic exercise on vertical pole known as "Shoulder Mount". The purpose was monitor the changes in two different conditions; i.e. kinesiotape and elbow brace and compare with the control condition for the reason of finding out their ability to affect the myoelectric activities of selected muscles. Further, the Shoulder Mount exercise had recorded by six Qualisys cameras for motion analyses. Methods and materials: The potentially eligible scientific articles perform a search of studies on the topic of kinesiotapes and tennis elbow brace as measured by EMG mainly on myoelectric activity of the shoulder complex were seared from...

EMG analysis of the influence of the water environment on walking in the elderly
Vodičková, Kamila ; Pánek, David (advisor) ; Neuwirthová, Svatava (referee)
Title: EMG analysis of the influence of the water environment on walking in the elderly Objectives: The main objective of this master thesis is to determine the degree of activation of selected muscles during walking on land and in water environment by using surface electromyography. The next component objective is to determine and compare dynamic co-contraction level of low extremity muscles during walking on land and in water. Methods: It is a pilot study which was attended by 5 participants. The average age of the research group was 67,2 years and was represented 3 men and 2 women. Activity of m. tibialis anterior, m. gastrocnemius, m. rectus femoris, m. biceps femoris and mm. erectores spinae in the level of ThL transition was recorded during walking on land and in water environment. EMG signal has been adjusted, analyzed and after that normalized EMG signal to MVC was compared in both environments. The records were compared both intraindividually and interindividually. At the end dynamic co-contraction level of selected muscles was evaluated and compared during gait in both environments. Results: Electromyographic analysis revealed that during walking in aquatic environment were analyzed muscles involved with less extent than during walking on land. Co-contraction level was lower in low...

An electromyographical analysis of the influence of water environment on the rehabilitation of patients with Parkinson's disease
Kotalíková, Kateřina ; Pánek, David (advisor) ; Pavlů, Dagmar (referee)
Title: An electromyographical analysis of the influence of water environment on the rehabilitation of patients with Parkinson's disease Aims: The main aim of this Master's thesis was to compare electrical activity of selected muscles of patients with Parkinson's disease via electromyography during gate aground and in water environment. Furhter aim was to determine co-contraction level of leg muscles of patients with Parkinson's disease during gait aground and in water environment. Methods: This thesis is a case study, which was conducted on five probands, two of which were men and three women of age 67,4±7,1. With the use of surface electromyography, an activity was evaluated of m.tibialis anterior, m.gastrocnemius, m. rectus femoris, m. biceps femoris and mm. erectores spinae in place of Th -L junction. Acquired EMG signal was analized and then a standarized level of muscle activity during gait in different environments was evaluated, aground and in water, and afterward a dynamic co-contraction level was evaluated. Results: The results show consistent standardized activity of monitored muscles in water environment, which describes a chronic influence of pathological central program accompanying Parkinson's disease, where a change in coordination pattern is not observed, typical for movement in...

Vojta reflex locomotion impact to the locomotor system of the patients with spinal cord
Kohutová, Veronika ; Špaňhelová, Šárka (advisor) ; Hyšperská, Veronika (referee)
The aim of this thesis was to evaluate the Vojta method therapy impact to the muscles function of the upper limbs of patients with tetraplegia. This is a pilot study, which was attended by five probands. To objectify the results, the method of surface electromyography was adopted. EMG activity of 14 muscles of the upper limbs and shoulder girdle during selected movements before and after therapy was recorded. The choice of therapeutic positions and activation zones was individual. Although a few muscles show significant changes, statistically considerable influence of the therapy cannot be confirmed from the obtained results. But from the point of view of clinical observation and patients 'subjective feelings an obvious difference can be seen. Therefore, it may be in the future advantageous to monitor the impact of Vojta method to locomotor system through clinical methods such as functional tests, tests of independence, range of motion or kinematic analysis.
