Interactive device supporting ankle joint rehabilitation
The paper is focused on development of a device supporting rehabilitation of the human ankle joint enabling also measurements of various parameters in order to diagnose the human state and its progress, as well as to characterize and personalise the therapy. First step in the device’s design was to identify its kinematics by performing type synthesis and finding possible solutions. Afterwards, a selection of motors, as well as elements of electric and electronic systems (including sensors) has been performed. The mechanical system of the research prototype in the form of 3D drawings was designed and a research prototype was built. In order to carry out the experiments a control system has been designed in Matlab Simulink and applied using a dSpace real time controller. Moreover, experimental modes have been prepared to be controlled with a built user graphical interface. Experiments in different modes and with various input parameters were developed and data of kinematic and dynamic parameters has been gathered.
