Introduction/Background Robots-assisted gait rehabilitation are used in association with conventional rehabilitation but it's necessary to improve their functionality. This paper presents a psychosocial intervention framework to support the development of a mobile robot for gait training: ROBO-K. The aim was to facilitate the integration of the robot in the walking rehabilitative process and thus, ensure its diffusion. Material and method The representation of the robot's use and its evolutions (i.e., the usual trajectory) has been first studied. Then two multicenter studies were performed in 2013 and 2015. In the first one, patients (n = 34) and practitioners (n = 74) were interviewed to define acceptable functional specifications (i.e., social acceptability). After this first study, a prototype was developed in collaboration with an industrial partner. In the second one, patients (n = 36) and physiotherapists (n = 4) tested the co designed prototype in ecological situation during 1 to 6 months (i.e., acceptance and appropriation). Results The results showed that the robot is perceived positively by the patients and the physiotherapists because it's perceived as useful to improve balance and gait and provide safety and motivation. This perception persisted along the experimental procedure. For the physiotherapists, the robot helped to better manage their inner physical effort. In the other hand, the mental load was high. The results seemed also very encouraging in terms of clinical effectiveness. For example, the FAC (Functional Ambulation Classifications) increases by 40% on average. Conclusion Finally, these psychosocial approach with industrial, clinical researchers collaboration is an excellent pathway for innovation conception.

Objective Robotic systems allow to initiate and facilitate the implementation of a movement executed by the patient. The objective was to test the interest of an innovative gait robot. Materials/patients and methods Eighteen patients 53.6 (± 11.1) years aged, with a functional ambulation category (FAC) 0 to 5, followed 3 sessions of 45 min/week with the mobile robot with body weight support during 4 weeks while maintaining conventional physiotherapy sessions. This evolutionary robot provides, in stationary mode balance training safely through suspension, and in mobile mode gait training according to various trajectories. FAC, 6 min walk test (6 min), 10 meters walking test (10 m), Berg balance scale, time up and go (TUG) were evaluated. Results Various exercises could have been proposed regardless of the patients’ walking stage. FAC was increased from 1.0 (± 1.0), 10 m time from 28.0 s (± 23.1), 6 min distance from 80.6 m TUG was improved from 19.6 s (± 10.7) and Berg score from 9.6 points (± 9.0). Discussion/Conclusion Balance and gait rehabilitation were facilitated by the reassuring device. An improvement of all the tests was observed. These results are encouraging and a randomized study is necessary to evaluate the benefit of Robo-K in comparison to a control group.

Consequence of dairy quota on farm value -The complexity of the mechanism fixing the dairy quota allocated of each producer, the important disparities between these producers and the lack of a clear legal principle make difficult the appreciation of the quota. Some people assert this quotas is linked to land, thus enhancing farm value. For some others it is only the result of the ability, or efficiency of the producer who may use it without restraint. But is it possible to give value to a given quota ? We may say undeniably that a good reference gives a feeling of safety to the farmer. And the bankers take it into account. But, except for the case of a governement takeover, the reference remains difficult to negociate among producers. An actual quota market does not exist., La complexité du mécanisme de fixation des références laitières à chaque producteur, les disparités importantes existant entre les différents producteurs et l'absence d'une définition juridique claire rendent difficile l'appréciation de. la valeur du quota. Pour certains, il est lié à la terre et donc valorise la propriété. Pour d'autres, il n'est que le résultat de la qualité ou de la compétence du producteur qui peut en disposer librement. Mais est-il possible de valoriser le quota dont on dispose ? Incontestablement une bonne référence sécurise l'exploitant. Et les banquiers savent en tenir compte. Cependant, sauf le cas du « rachat » par l'État, elle reste difficilement négociable entre producteurs. Il n'y a pas vraiment de marché de quotas., Bidet F.
