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...

Biomechanical gait analysis in cerbral palsy
Málek, Michal ; Tlapáková, Eva (advisor) ; Malá, Michaela (referee)
Title: Biomechanical gait analysis in cerbral palsy Objectives: The main aim of this work is to compare pressure values on feet of young man with cerebral palsy during for him normal gait, gait with French crutches in narrow (modified) and wide (natural) holding and with crutch held only at left hand. Methods: One 23-years-old proband with sapstic triparetic cerebral palsy was participated in a qualitative research (case studies). Young man was examined using the Pedar - X pressure measuring system. The proband was subjected to measurements with pressure insoles placed in his shoes. Natural gait measurement, narrow (modified) and wide (natural) crutches grip and crutche on left side all measurements with five repetitions were performed, each with four step cycle. Evaluated were the pressure distribution and the magnitude of the vertical force component. Results: Proband's gait showed considerable asymetry in the step cycle. The pressure distribution on the feet was more uneven during walking with the crutches narrow held against the natural gait. However, the greatest asymmetry and congestion of the left leg was created when walking with crutches with wide (natural) grip. During measurement with the crutch on the left, there were no significant decreases or increases in values. The vertical...

Gajdoš, Miloslav ; Jandová, Soňa (advisor) ; Janura, Miroslav (referee) ; Šťastný, Petr (referee)
Title: Influence of gait in high heels on posture, and division of pressure on the contact area level of the feet and the floor Objective: The aim of the dissertation was to verify how walking in high-heeled shoes influences the time and pressure parameters of the step cycle and posture during slow and very slow walking in low experienced wearers. Methods: The research study was an empirical, comparative intra-individual study. Pedar-X® measuring inserts (Novel, Munich, Germany) were used to measure the distribution of plantar pressures and to evaluate time parameters while walking on a conveyor belt at v1 = 0.97 ms-1 and v2 = 0.56 ms-1 in straight shoes and high-heeled shoes. SonoSens Monitor Analyzer® (Gefremed, Chemnitz, Germany) was used to assess posture. The research group consisted of thirty healthy women wearing high-heeled shoes occasionally (age: 21.8 ± 2.09 years, weight: 55.7 ± 4.05 kg, height: 1.66 ± 0.03 m). Anova test and paired t-test were used for statistical analysis, and the Cohen coefficient d was used to calculate material significance. Results: Significant differences in time and plantar pressure variables were found when walking in high-heeled shoes compared to straight footwear. For both types of footwear, walking speed only affected time variables, but not dynamic...

Bibliographic record SVOBODOVÁ, Jaroslava. The influence of the level and type of postural load on parameters of dynamic plantography during standing and walking. Prague: Charles University, 2nd Faculty of Medicine, Department of Rehabilitation and Sports Medicine, 2018, 124 p. Supervisor Mgr. Michaela Opálková. Abstract The thesis deals with the reaction of body to postural loading during stance and walking. The theoretical part of this thesis is focused on postural control and postural reaction during stance and walking. Particular attention is paid to gait cycle, dynamic plantography and Zebris FDM-T Rehawalk system, which has been used in the practical part of this thesis. Two chapter deal with postural loading, the first is focused on symmetrical loading (e.g. backpack) and second on asymmetrical loading (laptop back - ipsilateral, contralateral and held in hand). The practical part presents the examination of 32 volunteers who were either standing or walking on a dynamic plantograph. The volunteers were exposed to either symmetrical or asymemtrical 5 or 10 kg load. Subsequently, statistical tests were used to search for any change of dynamic plantography parameters depending on the level of loading, on the type of loading and in the comparison of the situation with and without loading. The results...
