This study is looking for Veterans who experience a combination of traumatic brain injury (TBI), post-traumatic stress disorder (PTSD), and chronic pain, often called the "polytrauma clinical triad." These conditions can lead to sleep problems and other difficulties. Researchers want to see if improving sleep can help with these interconnected issues. You might be asked to use a Morning Bright Light Therapy device or a Negative Ion Generator for 60 minutes each morning. The main goal is to measure how well you sleep using a wrist-worn device before and after four weeks of treatment. To join, you must be a Veteran, speak English, have phone and internet access, report current sleep disturbances, and have a documented history of TBI. You also need to be stable on any current treatments for depression, anxiety, sleep, or pain. The study is currently unclear on its recruitment status and plans to enroll 96 participants.

Study design

This is an interventional study, meaning participants will receive a specific treatment. It plans to enroll 96 participants, but the phase of the study is not specified.

What's involved

Participants will sit in front of a device (either a lightbox or a negative ion generator) for 60 minutes every morning for four weeks. Sleep will be measured using a wrist-worn actigraphy device before and after this period.

Compensation

Not stated in the trial record.

Follow-up

Sleep efficiency will be measured at pre-treatment and post-4 weeks of treatment.
