Estimating Human Movement Using Accelerometers
Matula, Tomáš ; Růžička, Richard (referee) ; Dobai, Roland (advisor)
Tato práce je zaměřena na analýzu lidského pohybu, zejména měření úhlu kolena, co je důležité především při procesu rehabilitace u pacientů s protézy kolenního kloubu nebo po operaci. Pro měření IMU - inerciální měřící jednotky od firmy Xsens jsou použité, přičemž pouze data z 3-osého akcelerometru a gyroskopu jsou zahrnuty. Vhodné umístění jednotek je vybráno, jakož i metody pro kalibraci a následný výpočet úhlu ze zaznamenaných dat. Tyhle metody jsou implementovány a experimentálně ověřeny. Experimenty ukazují, že výsledky jsou docela přesné, a toto řešení je použitelné při analýze pacientů například provedením monitorování chůze.

Title: Gait analysis of female basketball players Objectives: The main objective of this thesis is to perform gait analysis using Qualisys and Kistler systems in long time female basketball players and population that does not engage in any regular sports activity on competitive level. Selected spatiotemporal, kinematic and kinetic gait parameters are compared between measured groups. Methods: 20 female probands participated in this experimental study. Tested group consists of 10 long time female basketball players between ages of 21 and 29 (mean age of 24,5). Control group consists of 10 female probands between ages of 24 and 25 (mean age of 24,5) that do not engage in any competitive sport on regular basis. Qualisys Motion Capture system was used to gather 3D kinematic gait data. Ground reaction forces were measured by using Kistler force plates. Data was obtained by both systems at the same time. Evaluated gait parameters were walking speed, step length, pelvic and shoulder rotation range of motion in transversal plane, CG of foot range of motion and all ground reaction forces components. Two-sample t-test and Mann-Whitney U test with significance level of 0,05 were used for statistical analysis of obtained data. Results: Results of this study demonstrate that long time engagement in...

Analysis of processing Rehawalk data in patients after stroke
Řiháková, Emma ; Oplatková, Lenka (advisor) ; Pintarová, Sylva (referee)
Diploma thesis entitled "Analysis of Gait data utilizing the Rehawalk treadmill in post- stroke patients," is focused on investigating the gait parameters of individuals who have suffered a stroke and subsequently undergone analysis on the Zebris Rehawalk treadmill. This study specifically examines temporal and spatial parameters, including step length, anteroposterior Center of Pressure (COP) position, and lateral COP symmetry. The theoretical section of the thesis provides an in-depth discussion on stroke causes, clinical effects, and rehabilitation interventions. Furthermore, it provides an overview of the Zebris Rehawalk treadmill, employed for both analytical and therapeutic purposes, along with a delineation of its specifications. The central objective of this research was to determine how the aforementioned gait parameters evolve over time among post-stroke patients. The resulting values indicate the effectiveness of post-stroke gait therapy, which is an important component of independence and autonomy. The study includes participants who have experienced a stroke, the experimental cohort (n=24; females=5, males=19), as well as a control group, healthy individuals (n=47; females=32, males=15). The control cohort was utilized solely for the purpose of result comparison concerning...

The effect of minimalistic shoes on foot kinesiology
Vondrášková, Anna ; Tolar, Jan (advisor) ; Demeková, Júlia (referee)
The diploma thesis deals with the possible influence of barefoot (or minimalist) shoes on the kinesiological parameters of gait and possible changes in the stability of gait and standing. The theoretical section briefly describes the anatomy of the human foot, foot arches, foot movements and the gait kinesiology. The next chapter deals with the issue of walking in barefoot shoes and explaining the basic parameters of barefoot shoes. The theoretical section concludes with a summary of the results of studies already conducted on this issue. In the practical part, we did our own research on selected gait and standing parameters, which can be affected by changing the shoe type. Participants switched to a period of approximately six months from wearing conventional shoes to barefoot shoes, and the measurements were taken twice, before and after adaptation to barefoot shoes. To objectify the results, the same measurements were taken in a control group that did not change shoes. Five parameters were selected to evaluate changes of gait and three parameters related to standing stability. Keywords Barefoot, minimalistic shoes, gait, gait analysis, stance analysis, stability
