PhD field of research: robotic upper-limb exoskeleton for neurorehabilitation

Starting date: Jan 2014

Advisors: Prof. A. Roby-Brami, Prof. N. Jarrassé



During the weeks following a brain lesion, hemiparesis symptoms usually recover spontaneously but in a partial and inconstant way. Hemiparetic patients normally exhibit pathological synergies, meaning global and stereotyped unnatural patterns of movements that occur when they make any
effort to move. These impaired patterns of coordination, if not promptly and correctly treated, can encourage negative compensations in stroke survivors and potentially limit their motor recovery.
With the increasing demand for robotic neurorehabilitation, an important weight should therefore be devoted to strategies for assisting the patients in recovering “healthy-like” movements through efficient teaching methods. In fact, functional improvements, without considering negative compensations, risk to be ineffective.
Rehabilitation robotics been studied and tested since 25 years, and a wide range of solutions to control both exoskeletons and simpler planar robot is available. However, very few researches focused on the problem of controlling coordination in post-stroke patients and the clinical results are still not satisfying. Moreover, studies on physical human-robot interaction, when robotic devices are acting at the joint level on multiple interaction points, as in the case of exoskeletons, are lacking.
During my PhD, I will try to address the problem of improving the relearning process during the motor recovery of post-stroke patients, using a robotic exoskeleton. 
Based on the consolidated hypothesis of similitude between motor control learning in healthy and motor recovery of impaired patients, I will focus in particular on the following unsolved questions:
- How do people adapt when they perform motions in joint-level force fields, distributed along the upper-limb by a robotic exoskeleton?
- What are the parameters of the force-field, and thus the robot behaviour, which better influence the learning process in healthy?
- What are the best control strategies for rehabilitation exoskeletons to fulfil this purpose?
- How to produce challenging practice and provide assistance, maintaining high the motivation of the subject?
