We invite you to join our research registry for people with low back pain. To enroll in the PRECISION Pain Research Registry, you will be asked to answer questions approximately every three months. All study encounters may be completed electronically. You will be asked to provide a one-time saliva sample for analysis of DNA and other biomarkers. Due to COVID-19 emergency, we will only enroll remotely and the saliva sample will be required at a later date. You will be compensated for your time. You must be between the ages of 21 years and 79 years, and may not be pregnant to enroll in this registry. To learn more, please call 817-735-5410, or email us at firstname.lastname@example.org.
