Summary

This study follows 1,500 people with long-term pain who are joining rehabilitation programs. Researchers want to understand how insomnia symptoms influence pain, function, and work ability. The goal is to use this knowledge to improve future treatments for chronic pain.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could help design better rehabilitation programs that address both pain and sleep problems.
What could go wrong
This is an observational study, not a treatment test. It cannot prove cause and effect, and results may not apply to everyone.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Potential participants are patients referred to rehabilitation at five different Unicare rehabilitation centers in Norway (Unicare Helsefort, Unicare Coperio, Unicare Hokksund, Unicare Friskvern and Unicare Jeløy) due to long-term pain complaints. Potential participants are referred to outpatient or inpatient rehabilitation or a shorter assessment stay (where the goal is to assess what is the best treatment option for the patient). Referrals to the rehabilitation centers are done by the patients' general practitioner or by specialist healthcare. All referrals are considered at the regional unit for referrals (Regionalt henvisningsmottatak) in mid- or southeast Norway who judge whether they fulfill the criteria for rehabilitation in specialist health care.
