Taking regular walks when living with Parkinson’s disease has beneficial effects on movement and quality of life. Yet, patients usually show reduced physical activity compared to healthy older adults. Using auditory stimulation such as music can facilitate walking but patients vary significantly in their response. An individualized approach adapting musical tempo to patients’ gait cadence, and capitalizing on these individual differences, is likely to provide a rewarding experience, increasing motivation for walk-in PD. We aim to evaluate the observance, safety, tolerance, (...) usability, and enjoyment of a new smartphone application. It was coupled with wearable sensors and delivered individualized musical stimulation for gait auto-rehabilitation at home. Forty-five patients with PD underwent a 1-month, outdoor, uncontrolled gait rehabilitation program, using the BeatWalk application. The music tempo was being aligned in real-time to patients’ gait cadence in a way that could foster an increase up to +10% of their spontaneous cadence. Open-label evaluation was based on BeatWalk use measures, questionnaires, and a six-minute walk test. Patients used the application 78.8% of the prescribed duration and enjoyed it throughout the program. The application was considered “easy to use” by 75% of the patients. Pain, fatigue, and falls did not increase. Fear of falling decreased and quality of life improved. After the program, patients improved their gait parameters in the six-minute walk test without musical stimulation. BeatWalk is an easy to use, safe, and enjoyable musical application for individualized gait rehabilitation in PD. It increases “walk for exercise” duration thanks to high observance.Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT02647242. (shrink)

The agroecological transition of agriculture not only requires changes in practices but also in ways of thinking and in their underlying values. Agroecology proposes broad scientific principles that need to be adapted to the singularities of each farm. This contextualization leads to the identification of agroecological practices that work locally and could serve as evidence-based practices to be transferred to local practitioners. This strategy was tested in a 4-year experiment conducted with dairy-sheep farmers in the South of France. The aim (...) was to collectively engage in the agroecological transition. Our work focused on the creation of a diagnostic tool that was used to analyze local farms and identify virtuous practices to be promoted locally as evidence-based practices. But this strategy came up against the complexity and singularity of the situations to be transformed: not only was no evidence found but the construction of the diagnostic tool itself led to controversy concerning the models of agriculture to be promoted. The experiment then took a pragmatic turn: on-farm workshops were organized to enable farmers to benefit from the professional judgment of peer farmers who were willing to help their colleagues accomplish their agroecological transition. The diagnostic tool, which was designed to be prescriptive, was then used to judge the social acceptability of solutions that made sense in each farmer’s own situation. Our experiment led us to conclude that managing the agro-ecological transition of farmers and their farming system is better conceived as a value-based process than as an evidence-based one.

L’instrument de musique est abordé non pas isolément mais avec la musique dans laquelle il intervient et par laquelle il se réalise véritablement comme instrument de musique. Après des éléments de définition abordés en rayonnant autour de l’idée de Berlioz du « corps sonore utilisé par le compositeur », l’accent est mis sur le rôle de la pratique instrumentale et de la technique instrumentale. Sont décrites alors les diverses formes de l’identité de l’instrument (de l’identité-objet à l’identité-répertoire) puis ses potentialités (...) (les éléments sonores précis qu’il doit permettre de produire, comme les possibilités nouvelles qu’il va offrir au cours de son histoire). (shrink)
