About the trial
What the trial wants to find out
This study investigates how acute exercise-induced muscular pain affects sleep quality and sleep architecture in people with insomnia compared to healthy sleepers.
Read full original descriptionShow less
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 standardized 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.
The 2 groups in the trial
