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...
The use of the OhmTrak device in self-treatment of patients with back pain
Tyburcová, Marie ; Kobesová, Alena (advisor) ; Jačisko, Jakub (referee)
Introduction: Impaired trunk stabilization is a frequent cause of chronic low back pain (CLBP). Trunk stabilization training can reduce back pain. Aim: To determine the effect of the OhmTrak (OT) trunk stabilization training device following Dynamic Neuromuscular Stabilization (DNS) principles in patients with CLBP. Methods: A single-blind randomized clinical trial. The investigator did not know to which group the participant belonged. 20 patients with CLBP were randomly divided into 2 groups. 10 patients included in the experimental group underwent six-week DNS training focusing on optimal trunk stabilization. The participants had a treatment session with a physiotherapist once a week. Experimental group patients were educated in self- treatment with the OT device which they performed for 15 minutes 5 times a week. The control group patients (n=10) underwent the same rehabilitation program of the same duration and frequency including the self-treatment. Control group participants performed self-treatment without the OT device. Before the start and at the end of the 6 weeks therapy program the ability to activate the abdominal wall was assessed using DNS Brace device in all participants from both groups. All patients from both groups completed the Oswestry Disability Index (ODI) questionnaire at...
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...
Utilization of biofeedback sensors for the activation of breathing and postural function of diaphragm in patients with chronic low-back pain
Macigová, Lucie ; Oplatková, Lenka (advisor) ; Bitnar, Petr (referee)
This thesis is focusing on objectifying the postural function of diaphragm with a biofeedback sensor in patients with low back pain (LBP). The theoretical part provides an overview of known facts about the postural function of the abdominal muscles and diaphragm and the connection between their activation and the change in intra-abdominal pressure and the origin of LBP. The thesis gives specifics of LBP, its etiology and possible methods of classification of non-specific LBP, as well as the methods of evaluating subjective disability. Other methods of objectifying postural functions other than the one used in this thesis are mentioned briefly. Methodology: In the experimental part, we used a capacitive force sensor to test 31 patients with non-specific chronic LBP (aver. age 25.25, SD ± 4.66, aver. height 176.77 cm, SD ± 9.97, aver. weight 77.93 kg, SD ±18.40) in 3 posturally different seated scenarios - resting breathing, with added external load when the subjects held a dumbbell of 20 % of their body weight) and with maximum voluntary increase in intra-abdominal pressure (the diaphragm test). The sensor position was on lumbar triangle and in the groin area. Oswestry Questionaire v2.1a was used to evaluate subjective disability. Results: An independent t-test analysis showes increase in the...

Janoušek, David ; Jevič, Filip (advisor) ; Dyrhonová, Olga (referee)
The goal of this thesis is to contribute to discovering a method which can lead to objectification of support base of infants in prone position at the edge of third and fourth month. The motor development during first six months is described in this thesis based on literature search. Part of the thesis is dedicated to selected primitive reflexes and postural reactions. Furthermore, the work deals with objectification of support base of infants at the edge of third and fourth month. In the study were evaluated 10 infants (5 males and 5 females) with average age 14,01 ± 2,2 weeks. Distribution of support was assessed in three situations such as prone position, prone position with maximal rotation of head to the left and prone position with maximal rotation of head to the right. The results did not show significant difference in weight bearing the left and right upper extremity in prone position. However there was a significant difference in weight bearing in the upper extremities during head rotation. The upper extremity on the side of rotation was more loaded. The weight applied to the upper and lower extremities was significantly different in every evaluated situation. Upper extremities were always weighted more. Keywords Supporting base, developmental kinesiology, postural reactions, primitive...
