Kinematic analysis of an upper extremity motion for function orientation workouts within the robot aided motor rehabilitation

Artykuł przedstawia uniwersalną metodę umożliwiającą analizę ruchu kończyny górnej podczas motorycznego treningu funkcjonalnego, w którym równocześnie mobilizowane jest wiele stopni swobody stawów, na podstawie nagrań z niezależnych kamer. W artykule przedstawiony został algorytm przetwarzania wideo do przebiegów czasowych poszczególnych zmiennych złączowych modelu kończyny. Opracowana metoda może zostać wykorzystana do wspomaganej komputerowo analizy poprawności ruchów, która ma zastosowanie w zdalnej rehabilitacji domowej, w tym funkcjonalnej terapii zrobotyzowanej.This paper presents a universal method of the motion analysis based on recordings from independent cameras. It is destined to the motor, function- oriented treatment of an upper limb within with multiple degrees of freedom mobilized simultaneously. The description contains a video processing algorithm aimed in computing time series of joint variables for the limb model. The developed method can be used for computer-aided analysis of the motion correctness; particularly useful for remote-home-rehabilitation, including function-oriented robot-aided therapy

Study on the Applicability of Digital Twins for Home Remote Motor Rehabilitation

The COVID-19 pandemic created the need for telerehabilitation development, while Industry 4.0 brought the key technology. As motor therapy often requires the physical support of a patient’s motion, combining robot-aided workouts with remote control is a promising solution. This may be realised with the use of the device’s digital twin, so as to give it an immersive operation. This paper presents an extensive overview of this technology’s applications within the fields of industry and health. It is followed by the in-depth analysis of needs in rehabilitation based on questionnaire research and bibliography review. As a result of these sections, the original concept of controlling a rehabilitation exoskeleton via its digital twin in the virtual reality is presented. The idea is assessed in terms of benefits and significant challenges regarding its application in real life. The presented aspects prove that it may be potentially used for manual remote kinesiotherapy, combined with the safety systems predicting potentially harmful situations. The concept is universally applicable to rehabilitation robots
