Study Overview
Brief Summary
This study investigates the effects of remote interventions based on the exposure to one or more zeitgebers (i.e. adapted physical activity alone or combined with bright light exposure, or galvanic vestibular stimulation) performed several times a week during three months on older adults' sleep and quality of life.
Detailed Description
More precisely, the main objective is to investigate the effects of interventions on objective sleep measures of older adults with a sleep complaint.
The main hypothesis is that the quantity and quality of sleep will be improved after the interventions in comparison to the active control group.
The second objective is to study the effects of these interventions on quality of life, physical condition, anxiety, depression and cognition.

Outcomes
Primary Outcomes
Change in time in bed measured by actigraphy
Time Frame: Actigraphy is recorded continuously during one week before the intervention (baseline) and one week after the intervention (at 12 and / or 14 weeks after baseline, depending on the intervention).
Objective measure of sleep quantity, expressed in minutes and based on bedtime and wake time.
Change in sleep onset latency measured by polysomnography
Time Frame: Polysomnography is recorded one night before the intervention (baseline) and one night after the intervention (from 12 to 14 weeks after baseline, depending on the intervention).
Objective measure of sleep quantity expressed in minutes.
Change in sleep efficiency measured by polysomnography
Time Frame: Polysomnography is recorded one night before the intervention (baseline) and one night after the intervention (from 12 to 14 weeks after baseline, depending on the intervention).
Objective measure of sleep quantity expressed in % and defined as 100 \* total sleep time / time in bed.
Change in percentage of time spent in the different stages sleep measured by polysomnography
Time Frame: Polysomnography is recorded one night before the intervention (baseline) and one night after the intervention (from 12 to 14 weeks after baseline, depending on the intervention).
Objective measure of sleep quantity expressed in % of time spent in stage 1 sleep, stage 2 sleep, stage 3 sleep and in rapid eye movement (REM) sleep.
Change in wake time after sleep onset measured by actigraphy
Time Frame: Actigraphy is recorded continuously during one week before the intervention (baseline) and one week after the intervention (at 12 and / or 14 weeks after baseline, depending on the intervention).
Objective measure of sleep quantity expressed in minutes.
Change in total sleep time measured by polysomnography
Time Frame: Polysomnography is recorded one night before the intervention (baseline) and one night after the intervention (from 12 to 14 weeks after baseline, depending on the intervention).
