This article presents a mechatronic solution for rehabilitation devices supporting active and passive exercises in persons with motor dysfunctions of the upper limbs in the area of the elbow and shoulder joints. A planar positioner integrated with original software and a control system, served as the basis for creating the present solution. Bellman’s programming method was applied to optimize the motion trajectory of the planar positioner along with the upper limb undergoing rehabilitation. The design of the planar coordinate positioner and the components of the system for supporting a therapy conducted by a rehabilitation specialist are presented.Keywords

The aim of this study was to estimate the range of mechanical properties of the human stomach in order to use the collected data in numerical modelling of surgical stapling during resections of the stomach. The biomedical tests were conducted in a self-developed tensile test machine. Twenty-two fresh human stomach specimens were used for the experimental study of its general strength. The specimens were obtained from morbidly obese patients on whom sleeve gastrectomy was performed. Finally, data on mechanical properties of the stomach wall with detailed analysis of anatomical regions of the stomach have been presented.Keywords
