Chronic Sleep Restriction and Driving
- Conditions
- Sleep Deprivation
- Interventions
- Other: Chronic sleep restriction and driving simulator
- Registration Number
- NCT00560456
- Lead Sponsor
- University Hospital, Bordeaux
- Brief Summary
Young subjects and patients with nocturnal respiratory disorders are frequently involved in sleep-related accidents. This study assess the impact of chronic sleep restriction (4 hr of sleep during 5 days) or total sleep deprivation in young or mature healthy subjects or snorers on simulated driving, objective and subjective sleepiness and objective and subjective cognitive performances. The effects of recovery night on these parameters are also assessed.
- Detailed Description
Principal objective :
To determine whether chronic sleep restriction affects more snorers driving performances than healthy subjects' driving performances.
To determine whether chronic sleep restriction affects more young people driving performances than mature subjects' driving performances.
Secondary objective :
To determine whether chronic sleep restriction affects more snorers reaction time performance and sleepiness than non snorers subjects'.
To determine whether chronic sleep restriction affects more young people reaction time performance and sleepiness than mature subjects'.
To determine how age and snoring intensity affects the degradation of performance over the 5 days of sleep deprivation.
To determine age-related changes in the time course of sleepiness during 5 days of chronic sleep restriction.
To compare the impact of total sleep or chronic sleep restriction on driving performances according to the age and snoring intensity.
To determine recovery facilities to chronic sleep restriction according to the age and snoring intensity.
Study plan :
G2: Group of subjects:
* patients
* controls
B1: Baseline normal night:
One night of normal sleep
A2: Acute sleep deprivation:
Night 1: night of total sleep deprivation Night 2: night of sleep recovery
C6: Chronic sleep deprivation:
Night 1 to 5: nights of sleep restriction Night 6: night of sleep recovery
Experimental plan : S20 \<G2\> \*B1 \* A2 \*C6
