Šembera, Martin ; Kolář, Pavel (advisor) ; Tuka, Vladimír (referee) ; Šťastný, Petr (referee)
Analysis of diaphragm movement during its postural function using m-mode ultrasonography in conjunction with spirometry Abstract The diaphragm is a principal inspiratory muscle that, together with the abdominal wall muscles, regulates intra-abdominal pressure, important for the postural stiffening of the spine. This dissertation aimed to analyse the movement of the diaphragm during breathing and postural loading, in relation to changes in respiratory volumes and abdominal wall tension. The theoretical part summarizes the current knowledge about the respiratory and postural functions of the trunk muscles, especially the importance of the diaphragm in maintaining spinal stability and preventing low back pain. The experimental part deals with the evaluation of postural- respiratory movement of the diaphragm using M-mode ultrasonography in conjunction with spirometry and a device called DNS Brace. The assessment was performed during several scenarios that included breath-holding, tidal breathing and loaded breathing while lifting a weight with spontaneous or voluntary contraction of the abdominal muscles. This research suggests that when the postural demands increase, the diaphragm is displaced in a more caudal position not only during inspiration but also during breath-holding. The voluntary contraction of the...

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...

Correlation between evaluation of functional postural tests and ability to expand abdominal wall in low back pain population.
Krausová, Eliška ; Jačisko, Jakub (advisor) ; Kobesová, Alena (referee)
The theoretical part: The theoretical part of thesis shortly describes anatomy and kinesiology of lumbar spine. The second chapter contains the causes of LBP and alerts to red flags. Muscle stabilization system of spine and intraabdominal pressure are themes of other chapters. Techniques of intraabdominal pressure measurement and questionnaires of quality of life were described at the end of the theoretical part. Methodology: 36 patients (22 female, mean age = 41.86, 16 male, mean age = 40.07) with low back pain were evaluated in three positions. Every proband filled Oswestry Disability Index (ODI) before the examination. Trunk orthosis DNS Brace evaluated 8 seconds intraabdominal pressure in three tests - breathing stereotype test, diaphragm test and hip flexion test. DNS instructor evaluated the same three tests by aspection and palpation. The first half of the probands was evaluated first with DNS Brace, the second half of probands was evaluated first with DNS instructor. Results: A statistically significant correlation (r=0,479, p=0,003) between evaluations DNS Brace and DNS instructor was demonstrated in one out three DNS tests - diaphragm test. There was not a statistically significant correlation in the other two tests. There was not a statistically significant correlation between DNS Brace...

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...

Influence of intra-abdominal pressure on stability of the lumbar spine
Fridrychová, Dagmar ; Šorfová, Monika (advisor) ; Nováková, Tereza (referee)
Title of thesis: Influence of intra-abdominal pressure on the stability of the lumbar spine Definition of the problem: This thesis addresses the problem of the stabilization mechanism of the lumbar spine and the influence of intra-abdominal pressure on the stability of the lumbar spine. Objectives: The aim of my thesis is to locate, evaluate and process all available resources and to bring up the issue of IAP and its influence on the lumbar spine. The work should provide the widest possible insight into the problems of IAP effects on the stability of the lumbar spine, summarize differing opinions, and allow easier orientation in the isme. Method: The work is treated as a search, focusing on the processing and retrieval of literature concerning the issue. Studies included range from 1953 to present. To which I will use a variety of sources of literature, internet and consultation with the head of my thesis. Results: The increase in IAP, which is provided by a synchronous contraction of the diaphragm, pelvic floor muscles and m. transversus abdominis, can effectively stabilize the spine. But you can not determine with certainty whether this mechanism to support the stability of the lumbar spine is indeed used or the stability is provided by contraction of muscles, leading to an increase in IAP, and...

The objectification of postural function of abdominal muscles
Novák, Jakub ; Kobesová, Alena (advisor) ; Davídek, Pavel (referee)
This thesis evaluates the possibility of using objective measurements to assess the postural function of abdominal muscles. The theoretical part provides an overview of findings regarding postural function of the abdominal muscles and the context for their co-activation using intra-abdominal pressure. The results are summarized in the form of research studies relating postural function and low back pain (LBP). The overview of the methods used to measure intra-abdominal pressure and the abdominal muscle activity is the main focus. In this section, we present a new methodology for measuring the activity of the abdominal muscles by using pressure sensors attached to the abdominal wall in the areas of the groin and the lumbar triangle. Methodology: In the experimental part, we tested 35 healthy subjects (average age 21.26t, SD ± 1,62) in 3 posturally different seated scenarios: 1. resting breathing, 2. with added external load (the subjects held a dumbbell 20% of their body weight) and 3. with maximum voluntary increase in intra-abdominal pressure (the diaphragm test). Results: An independent samples t-test indicated that the pressure created by the abdominal wall for both sensors in situation resting breathing increases in situation external load (HA1: upper sensor p=0.0079, lower sensor p=0.0009). We...

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...
