Details and patient eligibility

About

Due to the limitations of current approaches to assess emergency paramedics' fatigue, a portable, quick, easy, and objective technique is required to be developed. The aim of the study was to investigate the reliability of automated pupillometry to assess mental fatigue based on a driver simulator.

Enrollment: 32 patients

Sex: All

Ages: 18 to 35 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• All participants held valid driving license of more than 2 years, with at least half of a year driving experience, had regular sleep pattern, normal or corrected to normal vision and no history of any psychiatric disorder.

Exclusion criteria

• None.

Trial design

32 participants in 1 patient group

fatigue

Description:

After enrollments, subjects were assigned to perform mental fatigue-inducing experiment-a 90 min of monotonous simulated driving task. They underwent repeated measurements of quantitative pupillary light reflex (PLR) using an automated quantitative pupillometer at baseline and at an interval of 30 min during the task. Subjective ratings, heart rate variability (HRV), and electroencephalography (EEG) were performed simultaneously.

Treatment:

Diagnostic Test: pupillometer
