Surface electromyography leg and trunk muscle in patients with Jumper's knee
Crhonková, Radka ; Valouchová, Petra (advisor) ; Čech, Zdeněk (referee)
The goal of this thesis is summarize the current knowledge about Jumper's knee. It also includes a brief summary of the anatomy and kinesiology of the knee and then a separate chapter is devoted to the etiology, clinical picture, investigations and treatment of Jumper's knee. On these findings has been prepared and compiled research project hypotheses. This research is to determine whcther, and what affects Jumper's knee in the human musculoskeletal system. To this end, we chose a method of surface electromyography and dynamic plantography for analysis of pressure distribution and reaction forces during foot contact with the plate. Attention was focused on the comparison of side differences and timing muscle trunk and legs during dynamic activities sdccted. The results were compared with a control group that consisted of healthy individuals. Powered by TCPDF (www.tcpdf.org)

Use surface electromyography in the clinical practice
Dobisová, Anna ; Crhonková, Radka (advisor) ; Demeková, Júlia (referee)
Surface electromyography is a non-invasive method of examination. Surface electrodes localized on the skin above the muscle record action potentials of particular muscles' motor units. Acquired EMG recordings enable to assess muscle activity, muscle fatigue or recruitment of particular muscles during the motion (timing) and muscle coordination. Modern EMG devices are compatible with a scale of sensors that record other biosignals and are able to synchronize them with EMG records. That's why SEMG is applied in neurology, physiotherapy, ergonomics, biomechanics, orthopaedics, prosthetics, sport and in other spheres. As a non-invasive method it has its advantages, but of course its limits as well. Powered by TCPDF (www.tcpdf.org)

The most common knee injury in volleyball
Přádová, Kateřina ; Crhonková, Radka (advisor) ; Čech, Zdeněk (referee)
A knee is the most complicated joint in our body. It is commonly injured during volleyball, mainly resulting as a knee pain syndrome or an acute rupture of an anterior cruciate ligament. In its theoretical part this bachelor thesis gives an overview of basic anatomy and biomechanics of the knee joint, it deals with the gender differences in morfology and neurophysiology and it contains a chapter dealing with biomechanics of the knee joint in volleyball. The second part of this bachelor thesis is a research study searching for the most common knee injury in volleyball, comparing differences among men and women and comparing differences between indoor and beach volleyball. The most quoted injury of the knee joint was the injury of the ligament, but as the most serious and the most common injury players named an overuse injury. We didn't manage to compare an incidence in indoor and beach volleyball due to the lack of data. We didn't find a significant difference in the incidence and a character of injuries among men and women.

The influence of manual centration methods of the shoulder joint on muscle action around the shoulder girdle - EMG analysis
Michálková, Veronika ; Crhonková, Radka (advisor) ; Lepšíková, Magdaléna (referee)
Author's first name and surname: Bc. Veronika Michálková Title of the diploma thesis: The Influence of Manual Centration Methods of the Shoulder Joint on Muscles Action around the Shoulder Girdle -EMG analysis Department: Klinika rehabilitace a tělovýchovného lékařství FN Motol Supervisor: Mgr. Radka Crhonková The year of presentation: 2013 Abstract: The thesis deals with the influence of therapy methods by Čapová on muscles action around the shoulder girdle. The surface electromyography has been set as the method of the analysis. Electromyography of 11 muscles of the shoulder girdle has been performed before and after the manual centring in 14 healthy patients while lying on the back as well as lying down and doing chosen motion exercises. The measurements in twelve people in both positions have been carried out with a pause of one week. One patient has been measured only in the prone position and one in the supine position. The muscles action before and after the centration has been evaluated according to Wilcoxon signed-rank test. Also the differences of the measurement have been compared and the sequence of the muscles involved into the action has been analysed. The relationship between the measured phenomena cannot be rejected, although the null hypothesis has been proven. Several statistically...

Use of power yoga for muscle imbalance
Melegová, Alena ; Crhonková, Radka (advisor) ; Němeček, Ondřej (referee)
Autor: Alena Melegová Institution: Department of Rehabilitation Medicine, Faculty of Medicine in Hradec Kralove Name of the Thesis: Use of power yoga for muscle imbalance Supervisor: Mgr. Radka Crhonková Number of Pages: 95 Number of Attachments: 33 Year of the Defense: 2014 Key Words: Power yoga, yoga, physiotherapy, posture, muscle imbalance, breathing, stability of the body The bachelor's thesis deals with the use of power yoga in muscle imbalances. The theoretical part describes the history and principles of yoga. It explains the difference between yoga and power yoga, describes principles of power yoga, its indications and contraindications to exercise. It also states the effect of yoga and power yoga on the human body. It explains the concept of pranayama and divides asanas. It describes the theory of muscle imbalance, states the most frequently shortened muscles and reasons for their shortening. In the practical part is investigates the sample of 15 probands who have had only little or no experience with power yoga workout. The main focus of this thesis is to confirm the positive effect of power yoga on the muscle imbalances.

The effect of the position of lower limb on activation of the vasti muscles
Pešková, Lucie ; Crhonková, Radka (advisor) ; Čech, Zdeněk (referee)
Bibliographic identification PEŠKOVÁ, Lucie. The effect of the position of lower limb on activation of the vasti muscles. Prague: Charles University, 2. Faculty of Medicine, Department of Rehabilitation and Sports Medicine, 2013. 73 s. Supervisor Mgr. Radka Crhonková. Abstract The purpose of this thesis was to investigate influence of the position of the lower limbs on selected thigh muscles activity. Special attention was paid to activity of mm.vasti. The first part summarizes the literature findings. Based on these theoretical findings, the research plan and hypotheses were subsequently prepared. For the purpose of this work, method of surface electromyography was chosen. The research was primarily realized in a group of 14 healthy individuals. Muscle activity was measured during selected physical activities in both open and closed kinematic chains. We were interested in how different settings of lower limb joints effect the activity and timing of mm. vasti and ischiocrural muscles. In the next part of the research muscle involvement was compared between the control group of healthy subjects and the group of people after plastic surgery of the anterior cruciate ligament. The results indicated some interesting trends, particularly in the timing of muscles. Some of the main outcomes of this work are the...
