Study Summary
The purpose of the research study is to understand the effectiveness of a six-week course of light exposure on cognitive functioning, mood, activity, and sleep in people that have suffered a head injury leading to a concussion.
Primary Outcome
The Pittsburgh Sleep Quality Index (PSQI) subscale measurement that was used is overall sleep quality, which is derived from question 6 on the assessment and uses a Likert scale of 0 to 3. A score of 0 represents "very good" sleep quality (better outcome), while a measurement of 3 represents "very bad" sleep quality (worse outcome).
Interventions
