Title of Study:

The Association of Pain, Sleep, and Occupational Engagement on Quality of Life in People Diagnosed with Complex Regional Pain Syndrome

Why is this study being done?

We want to understand what it is like to live with CRPS. This study will look specifically at how sleep, pain, and doing the activities that are important to a person can impact living with CRPS. There is not much research on sleep in CRPS. We think sleep, pain, and activity levels might work together to make things better or worse. If we can show the importance of sleep to understand the overall life experience of people with CRPS, doctors and therapists may ask about sleep more. It may also help us to develop new ways of improving sleep in people with CRPS.

How many participants will participate and how long will the study take?

We want to hear from at least 150 people living with CRPS. We need people to fill in the whole questionnaire. The study will collect questionnaires for 60 days.
