Project Description

Translations: RO


An increasing amount of people, especially elderly ones, face mobility problems often due to a stroke or some kind of accident. To increase their quality of life and reduce their dependence on others, physical rehabilitation is necessary. The aim of the rehabilitation is to enable the people to re-learn how to use their limbs and strengthen the affected muscles. The traditional way of performing rehabilitation is by helping the patients pefrorm repetitive motions. A physiotherapist is monitoring their effort and progress and adjusts the task and the motion respectively. However, due to the fact that different patients have different mobility problems, the pre-defined repetitive motions do not constitute an optimal rehabilitation scheme for everyone. In other words, the rehabilitation is not always personalised.


Our proposal is about designing a Biomecanically Enabled roboTic controllER for REstoring Human ABility (BETER REHAB). The idea is to use a robotic arm to improve the rehabilitation process of a patient. The robotic arm will be attached on the arm of the patient and will firstly detect the intention of motion of the patient. Based on this intention, it will calculate a trajectory of motion and will apply the appropriate force along that trajectory. This way, the patient will be free to perform any type of motion, not just the predefined ones, and receive the appropriate assistance from the robotic arm.

To be able to do this, the robotic controller needs to be aware of the biomechanics of the arm. Therefore a musculoskeletal model of the upper arm will be included in the feedback loop of the controller of the robot. To better estimate and understand the intention of motion of the patient, we will simultaneously measure the muscle activation of the upper arm and the current position of the arm segments. Finally, the idea is to apply enforced learning techniques to allow calibration of the system for each patient individually.


This project is 100% funded by UEFISCDI and is part of the P1 line of funding (Development of the national system of R&D). It is a Post-doctoral project with number 27/2018 with a total budget of 300.000 RON.

To conclude

I am getting very excited about starting my work on this project. It seems like a lot of work that needs to be accomplished within two years, but at least I will have great people to support me with this. Lucian Bușoniu will be the supervisor of this project and will bring his expertise in control and learning. Levente Tamas, even though not officially attached to the project, has already helped with the vision aspects of project. And of course, we will receive a lot of valuable feedback from our industrial partners. Polaris, a rehabilitation clinic in Cluj, will not only provide clinical feedback, but also help us recruit patients for trial runs. And finally MIRA Rehab will bring their expertise on rehabilitation through gaming and possible ways on how to integrate our platform with theirs.
