简要总结
The study aims to evaluate the accuracy and consistency of assessing trunk muscle strength using an isometric device (Pegasus, Leipzig, Germany). Thirty healthy volunteers will undergo maximal isometric strength testing with the device, repeated one week later to assess repeatability. Surface electrodes will measure muscle activation, while MRI scans will assess structural condition.
详细描述
The aim of the study is to assess the validity and repeatability of trunk muscle strength evaluation using an isometric device (Pegasus, Leipzig, Germany) and to investigate it. Thirty healthy volunteer participants will undergo testing of maximal isometric (non-moving) strength using this device. The same strength measurement procedure will be repeated one week later for all participants to determine if the measurements are repeatable, i.e., if the device is capable of providing similar strength data in two closely timed measurements. To assess whether the device actually provides reliable strength data for the trunk muscles, surface electrodes will be additionally placed on the involved muscles to understand the extent of neural activation of these muscles during the test. Additionally, an MRI examination will be conducted for all study participants to assess the structural condition of the trunk muscles.
