Mechanical design of stend for lower limbs prostheses dynamic testing
Taufer, Tomáš ; Robenek, Dětřich (referee) ; Paloušek, David (advisor)
This work describes design and realization of testing device for dynamic tests of foot prosthesis, made by methods of Rapid prototyping. Primary objective of design is to imitate the load on prosthesis during human gait. This task is accomplished by swing motion of prosthesis inside the frame of device during the loading of heel and tiptoe. Loading components can be removed and changed so the device can be used for different measurement like walking on an inclined plane. The result of this work is fully functional device including control program with many options to control the test. The result of test is to decide whether the foot prosthesis withstands the set of cyclic loads. The area of development of prosthesis by additive methods is young for the time being. It stands out especially with different materials, design, structure of prosthesis and fast process of production. Therefore this device can be used for testing of fatigue life of prosthesis made by additive methods.

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.
