Objective evaluation of postural function of abdominal muscles and intra-abdominal pressure Abstract This dissertation deals with an important mechanism of trunk stabilization, the increase of intra-abdominal pressure. Intra-abdominal pressure is created by the coordinated contraction of the diaphragm, along with the abdominal and pelvic floor muscles. Intra-abdominal pressure works in all directions, stabilizing the trunk while reduceing axillary compression of the spine. Intra-abdominal pressure is increased during activities that require demands on the stabilization of the spine. Intra-abdominal pressure and trunk muscle activity can be measured in several different invasive and non-invasive ways. In rehabilitation medicine, anorectal or gastroesophageal probes are most often used to measure intra-abdominal pressure and measurements are often supplemented by evaluation of muscle activation using electromyography. However, these measurements are costly, time consuming and inconvenient for patients. The most common tool for evaluating trunk stabilization in rehabilitation practice is digital palpation of abdominal wall tension. However, this evaluation method is subjective. Therefore, new pressure sensors have been developed that allow non-invasive assessment of abdominal wall tensionand thus also the...
