Kneeling is sometimes necessary to get to hard-to-reach places. Some professions require daily and long-term kneeling which can cause various knee injuries, some of which can develop into serious diseases such as osteoarthritis. In order to avoid such injuries, it is necessary to kneel in a way where the peak pressures on knees will be reduced as much as possible. Using the Tekscan platform, the experimental part of this thesis explores the influence of body position on the distribution of pressure on knees and feet while kneeling. The first, introductory part, gives a theoretical background on various parts of the knee joint, knee biomechanics and knee injuries and diseases which can be developed by kneeling. The second part contains some of the more important factors which affect the pressure distribution while kneeling. It also contains some conclusions about knee forces and their ratios from an already existing research papers. Third part is a comparison of instruments which were used or are still in use for kneeling pressure measurements. Fourth part is an experimental one and used as an overview of numerical, visual and graphic data measured in this thesis. 6 static and 1 dynamic measurements were carried out. Static measurements contain 2 measurements where the subject held a load in outstretched arms. Knee joint forces are calculated and compared in the fifth part. At the very end of the thesis, there is a conclusion drawn from the measured data.
