Mechanical Design, Control Choices and first Return of Use of a Prosthetic Arm

In the world of upper limb prostheses, few companies dominate the majority of the market. They propose different kinds of hand, wrist and elbow prostheses but their control is often difficult to understand by the patients. We have decided to develop new myoelectric prosthetic arm (elbow, wrist and hand) by axing our development on the use of new technologies and facility of use for the patient. In this paper, we are explaining in details the different kinds of prostheses currently proposed to the amputees, their advantages and their drawbacks, the descriptions of the patients' needs and the possible improvements of the product. We will develop the designing choices of our prosthesis and the movements it can realize. Then we will explain the simplified control of the product by the patient and its first reactions. Finally, we will conclude by the news ideas and the next researches to concretize.Comment: 6 page

Méthodologies de conception de systèmes dans le médical : prise en compte des spécificités utilisateurs

My accreditation thesis to supervise research (HDR) is intended to summarize my professional teaching experience, administrative responsibilities as well as my scientific research.My research focuses on design methodologies on products in the field of disability and health in general. Theoretical concepts such as User Centered Design, Scenario Based Design (design based on simulation methods), along with Participatory design and Action research provide the information enabling me to conduct experiments and create new concepts. New product developments are introduced in conjunction with therapists and hospital practitioners. By working with disabled people, who are the end-users, my experiments provide vision for new methods of design to integrate specific characteristics for them.The following document shows the synergy existing between my professional activities and my involvement in civic associations. The importance of interdisciplinary health – technology around end-users and my permanent implications in real situations with the many stakeholders of the design process make up the core beliefs of my motivation as an actor in our society.Ce mémoire d’Habilitation à Diriger des Recherche se veut être un résumé de mes activités professionnelles d’enseignements, de responsabilités administratives et de recherche scientifiqueLes activités de recherche sur lesquelles porte mon travail sont orientées autour des méthodologies de conception de produits dans le domaine du handicap et de la santé en général. Les concepts théoriques tels que la Conception Centrée Utilisateur, la Conception basée sur les Scénarios, la Conception Participative et la Recherche Action constituent les éléments me permettant de construire mes expérimentations et générer mes concepts. Des développements de produits avec des thérapeutes et des praticiens hospitaliers sont présentés. Des conceptions et fabrications de de produits avec des personnes en situation de handicap sont montrées. Ces expériences me permettent de proposer des méthodes de conception intégrant les spécificités des utilisateurs finaux dans le processus de conception.Je montre dans ce document, la synergie existante entre mes activités enseignements – recherche – responsabilités administratives – associations citoyennes. L’importance de l’interdisciplinarité techno-santé autour des utilisateurs finaux et mes implications permanentes sur le terrain avec les tous les acteurs de la conception constituent l’essentiel de mes motivations en tant qu’acteur dans notre société

Integrating the human factors characterization of disabled users in a design method. Application to an interface for playing acoustic music

International audienceUsers and uses inclusion in product design remains a challenge, especially when their characterization is very specific, which is the case with disabled persons. Many design methodologies integrating user exist, for example, User-Centered Design (UCD). The application of these methodologies results in custom product designs, but they haven't objective the motor activities characterization of stakeholders: people with disabilities. Our ambition is to characterize and model the motor specificities of these future users during the design process to adapt the man-machine interfaces to these motor performances. In this paper, we propose an adaptation of the UCD design process by integrating theoretical models and technological tools of motion capture. In conclusion an in response to identified needs of AE2M project (Ergonomic Adaptation of the Musical Material), we present an application of our approach in this context

Designing for physically disabled users: benefits from human motion capture – a case study

International audiencePurpose: The present study aimed to improve the design of an interface that may help disabled children to play a musical instrument. The main point is to integrate human motion capture in the design process. Method: The participant performed 20 pointing movements toward four selected locations. A three one-way analysis of variance (ANOVA) was performed in order to determine the most efficient input location. For each button position, we compared (1) the reaction time (RT), (2) the movement time (MT), and (3) the spatial variability of the movements. Results: According to the results obtained for RT and MT, one position was the most efficient button location in order to produce efficient movements. Conclusions: As the case study showed, combining the 3D motion capture system and the statistical analysis led to help the designers their design methodology and crucial choices

Vers une analyse de scénarios pour la conception d'outils chirurgicaux

Lors de la conception de produits innovants, il est indispensable que les prototypes soient testés par les utilisateurs tout au long du processus de conception. Dans le cadre de la Chirurgie Minimalement Invasive (Minimally Invasive Surgery ou MIS en anglais), nous avons l'intention d'impliquer fortement le chirurgien dans les propositions d'améliorations des nouveaux outils chirurgicaux, mais également dans les tests de la procédure opératoire innovante liée à ces outils. Pour répondre à ce besoin, nous avons abordé dans ce papier les notions de Conception Centrée Utilisateur, de Conception Participative et de Conception Basée sur les Scénarios. Nous détaillons également les travaux menés avec les chirurgiens qui nous ont permis de proposer des premières utilisations de prototypes lors de scénarios mettant en scène les utilisateurs. La fin de ce papier est consacrée aux premiers résultats d'analyse de ces scénarios

Automatized assessment of motor function in patients with NMD: MFM-Digital Study

International audienceGiven the progress of research and management in Spinal Muscular Atrophy (SMA), validated tools are needed to assess patients’ motor function. The Motor Function Measure assessment (MFM) is known as principal outcome measure of the motor function with an international recognition. It is a validated tool and sensitive to the change applicable in SMA.Clinicians from the Neuromuscular Diseases Department (Hospices Civils de Lyon, France) are developing the MFM-digital, an automated system to assess SMA patients’ motor function based on MFM. By using a Microsoft Kinect and a digital tablet, the objective is to improve reliability and acceptability of the MFM by lowering the measure’s subjectivity linked to heteroevaluation and by creating a hybrid serious-game.The feasibility study assesses the relevance of the system to capture postures and motions during a MFM test. Due to technological limits of capture by the Kinect sensor, 14 on 32 items may be recognized by the Kinect and 3 items by a tablet. In each case, the therapist scores items in live by referring to the MFM manual. Based on digital data coming from Kinect and tablet records, the principal investigator informs a blind score. The good correlation between items scoring by a therapist and items scoring on captured digital data show the possibility to use an algorithm to propose an automatic score.21 records of MFM were collected with Kinect and Tablet sensors. The first results are encouraging, showing a good concordance between the scores with tracks of improvements of the system in particular concerning the capture for weaker patients. The data supplied by the MFM-digital system bring additional data, in particular the duration of the items’ exercises and kinematic parameters.One interest of this work consists in creating an automatic measurement tool, based on the MFM-items, which has already shown its validity
