Message from Ron:
I have been following Benoît Bardy and reading his work and materials for a number of years and am personally looking forward to hearing him discuss how our patients use “self-produced” and “environmental” information to stabilize or destabilize postural synergies. There have been so many instances in my life where the need to destabilize a dynamic movement pattern preceded the need for stabilizing a pattern that appears to exist because of weakness. Benoît has a gift to interface the unique individual characteristics of postural control (motor signature) to the same individual’s characteristics of social interaction and response to the “existence” of others. His work will have an impact on how we look at social interactions that may be restraining ideal movement and motor “synchronization”. Just this verbiage gets me excited!
Information-Induced Destabilization of Posture and Movement
In this presentation, the role of information in the (de-)stabilization of postural dynamics will be addressed. I will present the postural system as a complex dynamical system composed of many interacting degrees of freedom, giving rise at the behavioral level to functional, adaptive, and efficient postural synergies. I will show how endogenous (i.e., self-produced) and exogenous (i.e., from the environment) information can be used to modulate the postural system for functional purposes, for instance during learning and rehabilitation. Illustrations will include (i) vision-based rehabilitation of posture after stroke, (ii) coupling of sound and posture during standing, (iii) music-induced stabilization of walking and running in both healthy participants and patients suffering from Parkinson's Disease.
Interpersonal Synchronization of Posture and Movement
The coordination between body segments during standing and walking, or between the body and the environment, has classically been studied individually. However, social interactions are essential parts of our daily life, and they constraint the way we stand or move in a group. In this presentation, I will review the recent literature on interpersonal coordination of posture and movement — the study of motor synchronization between people, and will illustrate the circular relation between postural control and social rapports: the way we stand and move in a group influences, and is in return influenced by, our social interactions. Recent results will be presented showing in various postural synchronization tasks the existence of individual motor signatures (IMS), how these IMS are influenced by the presence of others, and the way technology can be used to facilitate postural synchronization. The consequences for the rehabilitation of patients suffering from social disorders (schizophrenia, autism, social phobia) will be addressed.
Benoît G. Bardy earned his B.S., M.S., and PhD (1991) in Movement Sciences at the University of Marseille in France. He was awarded a Georges Lurcy fellowship and a NATO postdoctoral fellowship to continue his research on perception and action in virtual reality at Brown University in Rhode Island, USA. Upon completion of the fellowship he returned to Marseille and worked as a lecturer in Movement Sciences, developing research on perception-action and postural control. Selected as a new professor at the University of Paris (Paris-Sud) in 1999, he created there a Research Center in Sport Sciences, and entered the Institut Universitaire de France as a junior member (2001-2006). In 2005, Benoît returned to the south of France and founded a few years later EuroMov, the new European center for research, technology and innovation in movement sciences (www.euromov.eu). EuroMov is a new concept in the country, at the crossover between fundamental and clinical sciences, technological development, and health-oriented entrepreneurship. Today the center welcomes in a brand new (2500 m2) building located in Montpellier around 100 researchers, engineers, and entrepreneurs from 12 countries collaborating on various scientific and R&D projects related to Movement for Health, in general. The center hosts iMose – Interactive MOtion Simulator at EuroMov – the largest motion-based simulator in France (http://euromov.eu/project/i-mose-lab/). In 2012, Benoît was re-inducted into the Institut Universitaire de France (IUF, 22th promotion) as a senior member.
Benoît’s research is concerned with dynamical approaches to problems of coordination and control of movement, in real and virtual situations, with a particular interest for personalized technology-oriented rehabilitation. Benoît is the author of 200+ scientific articles and 380+ lectures, communications, and conferences worldwide. He is the current coordinator (2013-2016) of two large-scaled European research projects. ALTEREGO (www.euromov.eu/alterego) develops innovative rehabilitation methods to improve relational deficits of patients suffering from social disorders using virtual reality and humanoid robotics. BEAT-HEALTH (www.euromov.eu/beathealth) exploits the tight link between music and movement and delivers embodied, flexible, and personalized rhythmical auditory stimulation (RAS) in order to enhance health (walking in PD patients) and wellness (Running across the lifespan).
Benoît is consulting expert and an evaluator for the H2020 research program of the European Commission.
