Influence of Dynamic Neuromuscular Stabilization Approach on Maximum Kayak Paddling Power
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...

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...

Objectivization of Dynamic Neuromuscular Stabilization effect on foot supporting function using Senno Gait device
Hejdová, Tereza ; Kobesová, Alena (advisor) ; Davídek, Pavel (referee)
The thesis evaluates the immediate effect of one therapeutic unit that using Dynamic Neuromuscular Stabilization (DNS) on the foot support function. The aim of the experiment was to verify effect of a single DNS therapeutic unit would to the determined parameters. The main expected effect was the optimization of the dynamic function of the foot and achieving better stability during the stance phase of a gait cycle. Methods: For the study, the asymptomatic group of 30 probands aged 24-36 years, 10 men and 20 women was selected. Fifteen probands were randomly divided to two groups - fifteen experimental group and fifteen to the control group. Subjects enrolled in the experimental group were measured before and after one forty minute therapeutic unit of DNS concept. The control group underwent two measurements at the same time interval, but without the therapeutic unit. The Senno Gait instrument was used for measuring. It contains insoles with motion sensors. It collects the data at a 100 Hz sampling rate for 1 minute while walking at its own normal speed. Results: Compared to initial examination, the significant shortening of the standing phase in the left lower limb (p = 0.003) and in the right lower limb (p = 0.034) was observed. The gait rate was unchanged after the DNS therapy in the...

Testing of the postural function according to dynamic neuromuscular stabilization in healthy individuals
Hrdlička, Filip ; Vacek, Jan (advisor) ; Davídek, Pavel (referee)
The main objective of this bachelor thesis was to ascertain whether healthy individuals will show positive results in the testing of the postural function according to dynamic neuromuscular stabilization. Outcomes of this study should demonstrate whether the tests are too strict and individuals will show over-positiveness (false positiveness). Methods: Recruitment of the subjects was done via advertisement in the student groups of the 3rd faculty of medicine on the social media. Exclusion conditions were: chronic pain history, history of any surgeries and significant injuries, history of significant neurological and internal diseases. The subjective level of selfperception of health was assessed by visual analogue scale and inclusion condition was result 0 - 2. The study included men and women in the age range of 18 - 26 years. 13 tests of the postural function were assessed, three of them had two variations so there were 16 results. Every test included factors, which were rated on a scale 1 - 4. Arithmetic mean of all the factors in the test demonstrated general result of the test. Result ≤ 2,5 meant positivity of the test (pathology), result > 2,5 meant negativity of the test (physiological range). Results: 39 students were interested in joining the study, 12 of them were excluded for not...

Trunk muscle activity and walkin
Svobodová, Jaroslava ; Opálková, Michaela (advisor) ; Davídek, Pavel (referee)
Bakalářská práce Aktivita trupového svalstva při chůzi Abstract This thesis refers to the anatomy and the kinesiology of trunk, spine and pelvis. In addition, it deals with the control of gait and gait biomechanics. Nevertheless, the main aim of this thesis is to summarize the information on the activity of trunk muscles during walking. This includes also trunk muscle activity during modified walking. This part reviews the changes of trunk muscle activity in reaction to low back pain and to the changes in walking speed. Thesis is focused on the activity of abdominal and back muscles such as m. rectus abdominis, m. obliguus externus abdominis, m. obliguus internus abdominis, m. transversus abdominis and m. erector trunci. The thesis also includes a case study of a patient who suffers from chronic low back pain. The activity of some of her trunk muscles was recorded by surface electromyography. In addition, the patient was tested using the zebris Rehawalk FDM-T system.

Influence of DNS to kayak power Stroke
Davídek, Pavel ; Kobesová, Alena (advisor) ; Demeková, Júlia (referee)
The thesis deals with the possibility to influence the maximum power of kayaking stroke by the Dynamic Neuromuscular Stabilization approach. The most common injuries sustained during kayaking are affecting shoulders. The aim of this thesis was kinesiological analysis of kayaking movement. It shows patterns of shoulder muscles activity during the paddling cycle. Finally the thesis describes the Dynamic Neuromuscular Stabilization approach. Methods: Subjects were 20 flat water kayakers (mean age 21,85 +/- 2,37), which were randomized divided into two groups. Training of experimental group contained exercise according Dynamic Neuromuscular Stabilization approach. Specific exercise was chosen with DASH questionnaire. The same questionnaire was used at the end of the six weeks study to see the changes in the problems of the upper limb activity. The effect of the therapy was compared by maximum power of kayaking stroke, which was measured by paddling ergometer. Both groups were tested four times in 6 weeks. We followed also the actual effect of the therapy of Dynamic Neuromuscular Stabilization by measuring maximum power before therapy and immediately after exercise. Results: Maximum power of the stroke increased of 6,3% (p = 0,032) in experimental group. We found the positive effect of the actual...
