Contexte et enjeux<\/h2>\n\n\n\n

Si l’on tape le mot “stress” dans la recherche Google, on obtient imm\u00e9diatement 468 000 000 de r\u00e9sultats avec des titres tels que “le stress au travail\u2026”, “g\u00e9rer le stress au travail\u2026”, “que faire quand le travail vous stresse\u2026” et bien d’autres. <\/p>\n\n\n\n

Cependant, il n’existe pas de d\u00e9finition stricte de ce qu’est le “stress”. Au niveau physiologique, le stress est la r\u00e9ponse d’un organisme \u00e0 certains stimuli externes, ou \u00e0 un d\u00e9fi. En pr\u00e9sence d’un facteur de stress, le syst\u00e8me hypothalamo-sympatico-adr\u00e9nergique peut activer la r\u00e9ponse “combat ou fuite” par le biais du syst\u00e8me nerveux sympathique (SNS), ce qui entra\u00eene la lib\u00e9ration de cortisol et d’adr\u00e9naline pour stimuler l’adaptation de l’organisme au stress. Cela peut se traduire par des effets physiques tels que l’acc\u00e9l\u00e9ration du rythme cardiaque, la relaxation de la vessie, une vision en tunnel etc. Le syst\u00e8me nerveux parasympathique (PSNS) travaille de concert avec le SNS. Sa principale fonction est d’activer la r\u00e9ponse “repos et digestion” et de ramener le corps \u00e0 l’hom\u00e9ostasie apr\u00e8s la r\u00e9ponse “combat ou fuite”. <\/p>\n\n\n\n

En un sens, le stress est une r\u00e9action naturelle de l’organisme. Cependant, il existe de nombreuses \u00e9tudes montrant le lien entre le stress et les maladies. Cela signifie que ce n’est pas le fait d’\u00eatre stress\u00e9 qui cause des probl\u00e8mes \u00e0 l’organisme, mais le niveau de stress qui peut \u00eatre excessif pour un organisme, au point que le syst\u00e8me nerveux parasympathique ne parvient pas \u00e0 le ramener \u00e0 l’hom\u00e9ostasie.<\/p>\n\n\n\n

Objectifs<\/h2>\n\n\n\n

L’objectif de ce projet est de r\u00e9aliser une classification des niveaux de stress en extrayant des caract\u00e9ristiques des biosignaux acquis et en associant ces caract\u00e9ristiques aux informations de base sur le niveau de stress fournies par les sujets eux-m\u00eames via des questionnaires. <\/p>\n\n\n\n

Nous souhaitons \u00e9galement d\u00e9finir des sch\u00e9mas de stress conduisant \u00e0 la d\u00e9tresse, que nous voulons \u00e9valuer au moyen de mesures du niveau de cortisol le matin.<\/p>\n\n\n\n

Partenaires et financement<\/h2>\n\n\n\n

R\u00e9sultats<\/h2>\n\n\n\n

Le projet a permis de d\u00e9velopper un syst\u00e8me non invasif de quantification de niveau de stress.<\/p>\n\n\n\n

Une base de donn\u00e9es collect\u00e9e pour tester les algorithmes de classification du stress, avec l\u2019accord de la Comit\u00e9 d\u2019\u00e9thique \u00e0 Lausanne (CER-VD)<\/a>.<\/p>\n\n\n\n
