The Impact of Acute Pain on Sleep Parameters in the Insomnia Population and Healthy Controls: a Case-control Study
This study investigates how acute exercise-induced muscular pain affects sleep quality and sleep architecture in people with insomnia compared to healthy sleepers.
Sleep disturbances and pain often influence each other, creating a negative cycle; however, it remains unclear how acute muscle pain-such as delayed-onset muscle soreness (DOMS) after strenuous exercise-alters continuous sleep parameters and pain sensitivity differently in clinical insomnia populations versus healthy controls.
Participants will be divided into two groups: individuals with clinical insomnia and age- and sex-matched healthy sleepers. Both groups will undergo a standardised exercise protocol designed to safely induce temporary, acute muscular soreness (DOMS). Objective sleep parameters (measured via wrist actigraphy) and subjective sleep parameters (measured via sleep diaries), will be monitored before and after the pain induction. The primary goal is to determine whether individuals with insomnia experience greater sleep disruption and altered pain recovery trajectories following an acute painful event compared to healthy individuals.

Sleep diary: Total Sleep Time
기간: Day 0 to Day 14
|
Assessed using a daily consensus sleep diary.
Total Sleep Time is calculated as the total time spent asleep, derived from the total time in bed (bedtime to wake time) minus sleep onset latency and wake after sleep onset.
Higher values indicate longer sleep duration.
|
Day 0 to Day 14
|
|
Sleep diary: Sleep Onset Latency (SOL)
기간: Day 0 to Day 14
|
Assessed using a daily consensus sleep diary.
Sleep Onset Latency is the estimated time (in minutes) it takes to fall asleep after turning off the lights.
Lower values indicate better sleep onset.
|
Day 0 to Day 14
|
|
Sleep diary: Wake After Sleep Onset (WASO)
기간: Day 0 to Day 14
|
Assessed using a daily consensus sleep diary.
WASO is calculated as the total duration of wakefulness (in minutes) between initial sleep onset and final awakening, derived from the number of night awakenings multiplied by their average duration.
Lower values indicate better sleep continuity.

Sleep Efficiency is calculated as the percentage of time in bed spent asleep: [(Total Sleep Time / Total Time in Bed) × 100].
Total Sleep Time is derived from total time in bed (time between bedtime and rise time) minus sleep onset latency and nocturnal wakefulness (calculated from the number and duration of night awakenings).
Scores range from 0% to 100%, with higher percentages indicating better sleep quality.

|
|
Actigraphy: Sleep Onset Latency (SOL)
기간: Day 0 to Day 14
|
Measured objectively using a wrist-worn ActiGraph accelerometer.
Sleep Onset Latency is the time (in minutes) between the initial bedtime (lights out) and the onset of continuous sleep detected by the algorithm.
Lower values indicate faster sleep onset and better sleep initiation.
|
Day 0 to Day 14
|
|
Actigraphy: Wake After Sleep Onset (WASO)
기간: Day 0 to Day 14
|
Measured objectively using a wrist-worn ActiGraph accelerometer.
WASO is defined as the total number of minutes spent awake after initial sleep onset and before final awakening, as determined by epoch-by-epoch movement counts.
Lower values indicate better sleep continuity and fewer night awakenings.

Actigraphy: Sleep Efficiency (SE)

Sleep Efficiency is calculated as the percentage of time in bed spent asleep: [(Total Sleep Time / Total Time in Bed) × 100].
Values range from 0% to 100%, with higher percentages indicating better sleep quality and efficiency.

Muscle damage severity: Muscle pain
기간: Day 0 to Day 14
|
Muscle pain will be measured by an 11-point NRS, with 0 represents "no pain" and 10 indicating "worst imaginable pain".

Sleep Questionnaires: the Insomnia Severity Index (ISI)
기간: Day 0 and Day 7
|
The ISI is a 7-item self-report questionnaire assessing the nature, severity, and impact of insomnia.
Each item is rated on a 5-point Likert scale (0 to 4).

Sleep Questionnaires: The Pittsburgh Sleep Quality Index (PSQI)
기간: Day 0 and Day 7
|
The PSQI is a 19-item self-report questionnaire that evaluates sleep quality and disturbances over a 1-month time interval.
It generates seven component scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication, and daytime dysfunction.
Each component is scored from 0 to 3. The sum of these seven component scores yields a global PSQI score ranging from 0 to 21, where higher scores indicate poorer sleep quality.

Psychological measurement: Depression, Anxiety, and Stress Scale (DASS-21)
기간: Day 0, Day 7, and Day 9
|
Assessed using the 21-item Depression Anxiety Stress Scales (DASS-21).
The instrument consists of three 7-item subscales measuring depression, anxiety, and stress.
Each item is rated on a 4-point Likert scale ranging from 0 ("did not apply to me at all") to 3 ("applied to me very much or most of the time").
Sum scores for each subscale are calculated and multiplied by 2 to yield total scores ranging from 0 to 42 for each dimension (Depression: 0-42, Anxiety: 0-42, Stress: 0-42), with a total overall score ranging from 0 to 126.
Higher scores indicate greater levels of psychological distress/severity.

Assessed using the 7-item International Physical Activity Questionnaire - Short Form (IPAQ-SF).
The questionnaire measures the duration (minutes) and frequency (days) of walking, moderate-intensity activities, and vigorous-intensity activities performed over the last 7 days.
Total physical activity volume is calculated as MET-minutes per week (MET-min/week) using standardised MET energy expenditure values: Walking = 3.3 METs, Moderate PA = 4.0 METs, and Vigorous PA = 8.0 METs.
Total score is the sum of (METs × minutes × days) across all three domains, starting at 0 with no strict upper limit.
Higher scores indicate higher levels of overall physical activity.
