Abstract: The document presents the process of creating a tool for the rehabilitation of people with lower-limb dysfunctions. The monitored metrics, hardware, communication, and software layer of the entire solution were presented in a cross-sectional way. In addition, the work analyzed the possibility of using UWB technology (tags) and vision (using markers in the form of diodes) to monitor the position of hip, knee, and ankle. The tests showed that the system has an accuracy of 1.3 cm for monitoring movement in two dimensions and 5.8 cm for a three-dimensional reflection of the position of the said joints. Low cost, combined with low invasiveness in patient movements, easy application and high accuracy of received data as well as cooperation with companies interested in proposed research allows for further investigation on the proposed system.
