Study Procedure
Individuals with low back pain, who participate in the Quebec Low Back Pain Study, and their healthy household members, will be invited to join this study.
Participants will be asked to fill-in a short questionnaire and to send us a stool sample and a saliva sample.
All participation in this study is done from home. No need to visit the clinic.
Low Back Pain
The low back is one of the most common sources of pain in humans. For most people, pain lasts a few days or weeks, but some people develop chronic pain, meaning pain which lasts more than 3 months. Many structures may be involved in the generation of pain: muscles, joints, nerves and discs. Despite the existence of many treatment options – physical therapy, medications, injections and more – many patients continue to suffer from pain.
We're Looking for Participants
If you're an adult woman or man, and you suffer from low back pain which began more than 6 months ago, you're invited to join our study.
