Objective and primary endpoint:~Demonstrate that the NaoX measurement tool detects sleep deprivation in medical residents performing medical shifts.~The primary endpoint is the detection of a significant decrease in Coefficient Alpha Attenuation (CAA) between the pre- and post-sleep deprivation measurements.~The data analysis will be blinded to the measurement.~Secondary endpoints and objectives :~Demonstrate a link between the Alpha Attenuation Coefficient (AAC) measured by the NaoX measurement tool and the vigilance tests.~Endpoint: significant increase in PVT (Psychomotor Vigilance Task) time associated with a significant decrease in Alpha Attenuation Coefficient (AAC).~Demonstrate a link between the Alpha Attenuation Coefficient (AAC) measured by the NaoX measurement tool and the state of fatigue experienced.~Endpoint: significant increase in Karolinska Sleepiness Scale (KSS) score associated with a significant decrease in Alpha Attenuation Coefficient (AAC).~Experimental scheme:~3 cycles of 2 recordings with the NaoX measurement tool associated with a self-questionnaire and vigilance tests (approximately 30 minutes per recording), carried out before and after a night shift by a medical resident.~Population targeted:~Medical residents performing night shifts of at least 12 hours.
To develop an easy-to-use measurement tool for monitoring fatigue and alertness, particularly in sleep-deprived subjects.
