Davídek, Pavel ; Kobesová, Alena (advisor) ; Kolář, Pavel (referee) ; Matoulek, Martin (referee)
INTRODUCTION: The aim of this thesis is to identify the effect of trunk stabilization training based on Dynamic Neuromuscular Stabilization (DNS) on maximum kayak ergometer power output and reported self-disability in the shoulder girdle area. METHOD: Thirty flatwater kayakers of both genders (17 - 25 years old) were randomly divided into two groups. Crossover design was used for this study. Subjects in the experimental group (group A) integrated DNS exercises into standard flatwater training during the first phase. The control group (group B) conducted only common flat water training at the same time. After 6 weeks, the groups were switched. Then group B underwent the same DNS exercise with the same intensity and the same time. The intervention was the same for both phases and took 6 weeks. Group A performed only standard off-season training during the second phase. The maximum power output on kayak ergometer was measured three times (before study, after 6 weeks and after 12 weeks). Disabilities of the Arm, Shoulder and Hand (DASH) were analyzed at the same time. RESULTS: Initially, no significant differences in maximum power output on kayak ergometer and the DASH questionnaire score were identified between the groups. During the first phase the experimental group (group A) improved the maximum...

Abdominal wall activity in patients indicated for total hip replacement compared to the population without advanced coxarthrosis
Opichalová, Klára ; Kobesová, Alena (advisor) ; Oplatková, Lenka (referee)
Introduction: The aim of this study was to explore the relationship between postural stabilization insufficiency and severe coxarthrosis indicated for total joint replacement. Postural stabilization insufficiency was assessed by abdominal wall activity. Methods: 51 participants were recruited. 26 patients with hip arthrosis (13 males and 13 females) were included in the experimental group (mean age 70.5 years, SD 9.1) and 25 participants (10 males and 15 females) in the healthy control group (mean age 70.5 years, SD 7.7). The Ohmbelt device can be used to assess the intra-abdominal pressure indirectly via abdominal wall expansion measurement. The pressure sensor within the Ohmbelt device was attached to the abdominal wall at the area above the inguinal ligament (anterior sensor) and contralateraly at the trigonum lumbale (posterior sensor) by an adjustable belt. The pressure exerted by the abdominal wall wS monitored by the sensors. All subjects were measured twice (once with the anterior sensor, the second time with the posterior sensor) in 3 postural situations - resting breathing in the upright sitting position, the diaphragm test, and holding a 2kg dumbbell in front of the body in the upright sitting position. Results: No statistically significant differences (p>0.05) were found between groups...

Objectice evaluation of postural function of abdominal muscles and intra-abdominal pressure
Novák, Jakub ; Kobesová, Alena (advisor) ; Mezian, Kamal (referee) ; Janoušek, David (referee)
Objective evaluation of postural function of abdominal muscles and intra-abdominal pressure Abstract This dissertation deals with an important mechanism of trunk stabilization, the increase of intra-abdominal pressure. Intra-abdominal pressure is created by the coordinated contraction of the diaphragm, along with the abdominal and pelvic floor muscles. Intra-abdominal pressure works in all directions, stabilizing the trunk while reduceing axillary compression of the spine. Intra-abdominal pressure is increased during activities that require demands on the stabilization of the spine. Intra-abdominal pressure and trunk muscle activity can be measured in several different invasive and non-invasive ways. In rehabilitation medicine, anorectal or gastroesophageal probes are most often used to measure intra-abdominal pressure and measurements are often supplemented by evaluation of muscle activation using electromyography. However, these measurements are costly, time consuming and inconvenient for patients. The most common tool for evaluating trunk stabilization in rehabilitation practice is digital palpation of abdominal wall tension. However, this evaluation method is subjective. Therefore, new pressure sensors have been developed that allow non-invasive assessment of abdominal wall tensionand thus also the...

Objectification of the effect of physiotherapy on the activation of the abdominal wall in patients with chronic low back pain
Hoffmannová, Barbora ; Kobesová, Alena (advisor) ; Zahradník, Petr (referee)
This bachelor thesis in the form of research deals with the issue of vertebrogenic lumbar spine syndrome, its formation, examination and therapy and possibilities of objectification of therapy. The theoretical resumes the present knowledge of motor control, postural functions, spinal stabilization system and vertebrogenic lumbar spine syndrome. It also provides possibilities for therapeutic influence and objectifying physiotherapy. The thesis also presents two case studies of vertebrogenic lumbar spine syndrome, which were examined with a new Ohm belt device that measures the strength of postural stabilization and abdominal wall activity. The parameters of spinal stabilization and the amount of activation of the abdominal wall were measured before and after treatment, and the results were compared. The subjective effect of therapy was evaluated by a standardized Oswestry questionnaire assessing pain and disability. Measurement results in both patients in increased activation of the abdominal wall after therapeutic intervention. The result correlates with the subjective perception of therapy of reducing pain and alleviating disability in both patients. Keywords vertebrogenic lumbar spine syndrome, spinal stabilization, objectification of therapy, Ohm belt, Oswestry questionnaire

Measurement of abdominal wall activation in developmental postural positions using Ohm Belt device
Svoboda, Petr ; Kobesová, Alena (advisor) ; Mádle, Kateřina (referee)
Introduction: The aim of this work was to determine the difference in abdominal wall expansion and thus indirectly the amount of intra-abdominal pressure in various postural positions, first without any correction, then after verbal and manual instruction according to Dynamic Neuromuscular Stabilization (DNS) principles. The amount of activation of abdominal wall muscles in various postural positions helps determine the positions in which optimal postural stabilization is best activated. These positions may be suitable for postural therapy and training. The theoretical part introduces optimal trunk stabilization according to developmental kinesiology principles and DNS concept. Then, the relationship between the intra-abdominal pressure and postural activity of abdominal muscles is introduced as well as the most common methods of objectification. Participants and Methods: 30 healthy subjects (15 women and 15 men) aged 20 to 25 years (mean age 22.73 years, SD 1.88) were tested using the Ohm Belt device. This device uses pressure sensors that are attached to the abdominal wall in the area above the groin and in the trigonum lumbale and thus allows non-invasive monitoring of abdominal wall expansion and indirect measurement of the intra-abdominal pressure. The subjects were tested in five postural...

Burgetová, Dominika ; Šteffl, Michal (advisor) ; Hráský, Pavel (referee)
Title: Effect of mobility exercises in offline and online environment on subjective perception of back pain Objectives: The main goal of this work was to determine whether the onset of daily mobility contributes to the reduction of individual's back pain perception. Within the work the results between the offline and online group was compared. Methods: The diploma thesis has the character of qualitative research, where case study of 20 probands was applied. Online input and output questionnaires were compiled to obtain data, which respondents filled in at the beginning and end of the intervention. Results: The research included 11 women and 9 men aged 21 - 44 years. Individuals have mostly sedentary jobs and some of them play recreational sports in their free time. At the end of the intervention, all individuals showed an improvement on the scale of the pain intensity, when the perceived back pain was alleviated or disappeared. The offline group performed better than the online group. Conclusion: The study confirmed that the inclusion of daily mobility contributes to the reduction of subjectively perceived back pain. It confirmed that exercising in offline lessons is more effective than in an online environment. Keywords: mobility, back pain, diaphragmatic breathing, torso stabilization, DNS

Correlation between clinical evaluation by functional postural tests and ability to activate abdominal wall measured by digital pressure sensors
Stříbrný, Martin ; Jačisko, Jakub (advisor) ; Kobesová, Alena (referee)
The theoretical part of the diploma thesis describes the role of abdominal muscles in intra-abdominal pressure and the effect on postural stabilization. The issue of postural stabilization was analyzed in a physiological situation and frequent pathologies related with inadequate postural stabilization have been described. The current possibilities of evaluating the activity of abdominal muscles and intra-abdominal pressure were presented. Methodology: 25 healthy probands (mean age 22.4 years, SD ± 1.76) were evaluated in five posturally different situations - breathing stereotype test, intra-abdominal pressure regulation test, diaphragm test, hip flexion test and arm elevation test. Testing was performed with a prototype of the DNS Brace digital pressure sensor. The resulting pressure values of the abdominal wall expansion were correlated with the corresponding postural tests according to the DNS concept, which were performed by two DNS instructors with more than five years of experience. Results: A statistically significant correlation (p = 0.001 to 0.24) between abdominal wall pressure values and palpation-evaluated postural tests was demonstrated in four of the five tested positions. Correlation was strong in diaphragm test (r = 0.75 and 0.661) and mean in other tests (r = 0.567 to 0.415). Only...
