Exoskeleton for children with Multiple disabilities

You are here

Technological innovation


Childrens suffering from multiple disabilities, cerebral palsy and neurological injuries or disorders lack the ability to walk, and so a project was proposed to design a motorized exoskeleton to educate these individuals to walk, those less affected by musculoskeletal impairment. This undertaking is an integrated part of the rehabilitation process (sessions of 20 to 30 minutes). The equipment is destined to be shared amongst several institutions and be dispatched in the different countries from interreg from 2 Seas. A review of exoskeleton state of the art emphasizes a blatant lack of such apparatus to meet the specific needs of childrens with multiple disabilities. Preliminary work has lead us to define a set of specifications and also, to identify a number of technological obstacles for resolution. Developping a support for Walking will be helpful for this major life activity for these child. The ultimate goal: for them to walk, thanks to the generation of human steps by the exoskeleton which each child would wear. These walking steps, derived from real human movement, have already been programmed into humanoid robots (Aldebaran Robotics NAO) and is currently in progress on a new specific exoskeleton structure existing at HEI. We are searching for clinical partners which are specialized in walking schemes and EMG , engineering laboratories dealing with balance and walking and or with eyes tracking and/or face emotion recognition

Overall objective

Our ultimate goal is to develop an exoskeleton of leggs wich will be abble to perform a Walk in an totally autonomous way. Importantly, this study will provide an evaluation of the possibility of promoting psychomotor development, where it is naturally blocked in disabled children, by using special technological means of motor education. In addition, this study is developing news communication interfaces through visual or audio stimulations, in modular and repeatable fashion. These new interfaces will be evaluated. In fact we want to propose a new assitive technology adaptable at each children for dayly readaptation use.First,this exoskeleton provides a new approach in the practice of motor Rehabilitation of children by mechanical stimulation tailored and scalable. We want to prove that the technology is a true auxiliary to the personnel specialized in rehabilitation for populations of children with neurological diseases. MOTION's only aim is to offer them the sensations of walking, happy to stand on the legs, the pleasure of seeing their environment differently, the benefit of the right posture, the welfare of a confinement broken by technologies that today opens doors to until then unthinkable solutions.

We Want to deliver : Technical points -An exoskeleton of leggs wich will be abble to perform a Walk in an totally autonomous way. Clinical Point -A clinical evaluation of an evaluation of the possibility of promoting psychomotor development -A clinical evaluation of the possibilities of improving arousal through visual or audio stimulations Both : - a system for measuring physiological parameters (heart and EMG) integrated in an intelligent clothing News communication interface

Expected result

Technical points The current technological obstacles are : Control of the balance and posture during Walk. We will propose a resolution based on a control of ZMP, posture and ground pression supervised by a smart system in a totally securised manner. The control of balance for exoskeleton could be transfer to other population like childrens with paraplegia. To perform a measure of physiological signals (heart, EMG...) we need to develop smart connected textiles that will be useful for other population in case of hospital at home for example Clinical points The current clinical obstacles are : How to evaluate the acceptability of an mechanical structure without hurting those childs wich are not communicants. The clinical protocols will be adaptable for other population like children with autism. We will propose a resolution based on the used of an existing orthesis called "Innowalk" for the acceptability and use of the capabilities of NAO robot to stimulate child in modular and repeatable fashion which allow to assess the evolution of child's arousal Expected results for childrens with multiple, more severe disabilities are likely to need ongoing support. These AT is essential, for many children with multiple disabilities. With the exoskeleton those childs will have the ability to walk, to stand, to lift, and to bend.

Cross-border added-value

We want to share : Supported new methods for childrens with multiple disabilities to walk and to stand. Supported new methods to stimulate childrens with new communication interfaces. New supported methods for taking care of this kind of population.
