Kinematic analysis dinamic neuromuscular stabilization tests in people with low back pain.
Burešová, Vendula ; Valouchová, Petra (advisor) ; Kobesová, Alena (referee)
The main target of this thesis was to detect objective changes in the implementation of four postural locomotor tests DNS and during walking. The movements were recorded using the optical MoCap - the kinematic analysis Qualisys. The particular interest of the investigation was to determine the current stabilization of the spine system in individual subjects aged 25 to 55 years, which was documented by means of the angular deflection of each segment, the flat segment deviation or the shift of the marker in a coordinate system. The measurement results were compared between ten individuals with LBP and ten persons without any difficulty who were placed into the control group. The data were collected using the software QTM and Visual3D and subsequently were statistically processed. A statistically significant difference was observed during walking when comparing the angular deflection of the pelvis to the chest at the rotation and lateroflexion (ř). The significant difference of the pelvis shift toward the chest during flexion and rotation (ř) was showed in a deep squat test, but the difference was not confirmed in lateroflexion (ř). Furthermore, no statistical difference of the lateral deflection of the same segment (pelvis or chest) (cm) in patients with LBP compared to all subjects during the...

Rybář, Adam ; Musálek, Martin (advisor) ; Tlapáková, Eva (referee)
1 Title: Manifestation of cerebellar dominance in the form of extinction physiological syndrome on upper and lower limbs and its relationship to human laterality. Objectives: The aim of this diploma thesis is to determinate size of relationship between manifestation of cerebellar dominance in the form of extinction physiological syndrome and preference of limbs. Methods: A total of 27 individuals (male and female students of UK FTVS) were involved in the current quantitative research. We used indicators which were selected from Musalek's test battery (2013) to assess limb preferences. The evaluation of joint passivity asymmetry was based on angle and time parameters during walk and during controlled falls of forearm and shank on a constructed fall-machine. The movement was registered in real time by Qualisys Motion Capture System. For data analysis, descriptive statistics methods, paired t-test, level of statistical and substantive significance (Cohen's d) and tetrachoric coefficient of correlation were used. Results: Our research suggests that there is no significant difference in joint passivity when comparing preferred and non preferred limbs. Though it is necessary to take into consideration specifics and the size of research sample in which everybody was an active athlete. The result of tetrachoric...

Experimental investigation of human gait analysis parameters
Hrušková, Natália ; Vilímek, Miloslav (advisor) ; Goldmann, Tomáš (referee)
Title: Experimental investigation of human gait analysis parameters Objective: The main objective of diploma thesis was an experiment, that examined kinematic and dimensional parameters of human gait which was captured by several cameras and acquired data was recorded in 2D and 3D measurement. Secondary objective was to compare and statistically evaluate data acquired from measurement. The objective of analysis was to discover and describe possible regularities, patterns of human gait and other connections in investigated subjects. Methods: Comparative method was used in the thesis. The purpose of the experiment was to compare parameters measured during attempts of every subject that were conducted under different conditions (different velocity, dressed, undressed, in the environment of 2D and 3D recording) and also to compare different subjects with each other. Results: In the experiment we observed that it is possible to prove the relation between the length of a step and the velocity of gait and also the relation between the change in the body height and the velocity of human gait by three dimensional recording of gait and its analysis. This contention was confirmed in the comparison dressed and undressed subjects. The result of the experiment was, that with increasing velocity of gait is...

The effect of kinesiotaping for flat foot correction in association with selected parameters of gait for a specific group of people
Michalcová, Eliška ; Zahálka, František (advisor) ; Heller, Jan (referee)
Title: The effect of kinesiotaping for flat foot correction in association with selected parameters of gait for a specific group of people Objectives: The primary objective of this experiment was to determine whether and to what extent the application of kinesio tape to flat foot (utilising a functional correction technique) can influence the positioning of the specific segments of the body and thereby implement change to walking stereotype. Methods: Biomechanical measurement of the gait of eleven specifically selected people with the clinical symptoms of flat foot was implemented. First we recorded measurements prior to the intervention and then again, subsequent to the application of kinesio tape for a defined period. Probands retained the tape in place for the following four days and then the measuring was repeated both prior and subsequent to the removal of the tape. To determine any potential changes to the statics, initially the measuring of the postural stability prior to the intervention was first implemented in the experiment and subsequently again when the kinesio tape was removed after it had been worn for four days. This measurement was carried out using the Footscan apparatus (RSscan International, Belgium) and any potential differences in six variant modes of posture were determined....

The evaluating of the change of walking quality in dancers in comparison with the normal population
Korošová, Kateřina ; Vilímek, Miloslav (advisor) ; Goldmann, Tomáš (referee)
Thesis name: The evaluating of the change of walking quality in dancers in comparison with the normal population Thesis goal: This thesis deals with effect of long-term ballet dance on kinematic parameters of gait. The theoretical part includes basic characteristics of gait cycle and kinesiological and biomechanical findings of ballet movement and its compensatory mechanisms in musculoskeletal system. There is analyzed angular parameters of gait cycle in ballet dancers in performance of walking in the experimental part. The results will show if the many-years intensive training of dance affects the alignment of particular joints of the body during human walk. Method: Kinematic analysis by Qualisys system allowing automatic processing of record obtained with infrared cameras. Qualisys uses its own high-frequency cameras for precise movement tracking of the measured object using active or passive markers. Gathered data from device were processed and statictically evaluated with Microsoft Office Excel.

Selected parameters of gait and foot in consideration of the individual's body height
Strnadová, Hana ; Vilímek, Miloslav (advisor) ; Goldmann, Tomáš (referee)
Title: Selected parameters of gait and foot in consideration of the individual's body height Objectives: This thesis deals with a dependence of the selected gait and foot characteristics on a person's body height. These parameters are compared between a group of men and a group of women. In addition, a validity of selected formulas used for a determination of body height is evaluated. Methods: Mutual relation among the gait and foot characteristics and the individual's body height is observed. The thesis is a descriptive - association research, the comparative method is chosen in the practical part of the thesis. For an objectification of the research, the Plantograph and the 3D kinematic gait analysis performed by Qualysis system was used. Results: It was found out that the selected formulas used for a determination of body height are valid. The best results are brought by the formulas which count with a length of a bare foot, the length of a step and a double-step. On the contrary, the worse results are achieved by using the formulas which count with the dimension of shoe print. A tight dependence of the foot length and the length of the step / double-step on the body height was proven. A minimum dependence of the foot width on the body height was proven. Nevertheless the foot width is verifiably...

The relationship between postural stability and physical activities
Gryc, Tomáš ; Zahálka, František (advisor) ; Janura, Miroslav (referee) ; Vavák, Miroslav (referee)
In the study "The relationship between postural stability and physical activities", we focused on determining the level of postural stability and the possibility of influencing by appropriate means of exercise intervention in people with increased physical activity and persons with physical limitations. Persons with increased physical activity were top players and players competing in various sports (football, handball, volleyball, golf) and those with physical limitations, patients suffering from diseases that have a negative impact on postural stability (Friedrich's ataxia, autosomal dominant spinocerebellar ataxia, Charlot-Marie- Tooth). Upright posture in stance and movement is a fundamental prerequisite for human bipedal locomotion. Postural stability is the ability to maintain an upright posture, which advises the motor and coordination skills, and its meaning is close to equilibrium abilities. Maintaining an upright posture is ensured by muscle activity, which is controlled by the central nervous system based on information from internal and external environment. Control of postural stability is the primary prerequisite for successful movement and as such it can be developed on the basis of appropriate physical activities. All methods of measuring static and dynamic postural stability can be...

Kinematic of cervical thoracic spine in the context of whole body posture
Vláčilová, Ivana ; Šorfová, Monika (advisor) ; Tlapáková, Eva (referee) ; Ravnik, David (referee)
Title: Kinematic of cervical thoracic spine in the context of whole body posture Problematics: This work describes the kinematics of upper thoracic spine during specific movement of the shoulder girdle. The kinematic changes are evaluated with the relationship of the whole body posture. Aim: To develop the objective evaluation of the posture and the amount of the segmental spinal movement of cervical thoracic spine. To describe the relationship between the specific movement of arm - adduction and external humeral rotation - and the posture using 3D kinematic analysis. To objectify this tested movement as a diagnostic tool or a therapy for forward head posture. Methods: The theoretical part of this work summarizes the current knowledge of poor posture and there is defined the upright posture. The experimental part describes the measurement of the movement of shoulder girdle and its response to the axial system using 3D kinematic analysis. Result: The results of kinematic 3D motion analysis show that the external humeral rotation with adduction of the shoulder leads to the upright posture if there is the horizontal position of the thorax and pelvis. The posture was divided due to the physiological or pathological response with this simple movement. Conclusion: A new model for evaluation of the...

Experimental motion analysis of human locomotion
Málková, Monika ; Vilímek, Miloslav (advisor) ; Goldmann, Tomáš (referee)
Title: Experimental motion analysis of human locomotion Objectives: The aim of this work is verification of the hypothesis that it is possible to identify humans using measurement of parameters of their gait taken from surveillance camera's records. Methods: In our thesis we used the method of comparison. The aim of the experiment is comparison of parameters measured in different trials of each subject under different conditions (different walking speeds, with or without clothes on, and using either 2D or 3D record), as well as comparison across different subjects. Results: We found that using a 3D record of human gait, it is possible to improve our capability of identifying them. We also found that it is necessary to compare either dressed subjects strictly among themselves or stripped subjects strictly among themselves, because otherwise the comparison is not meaningful. Furthermore, we found that using our geometrical methods, it is possible to deduce gait parameters from a 2D camera record when it comes to height of the subject, but not so for length of their step. Keywords: gait, identification, kinematic analysis, forensic biomechanics
