We invite you to join our research registry about low back pain, known as the PRECISION Pain Research Registry. If you qualify, you will be asked to answer questions approximately every three months for one year. All study encounters may be completed electronically. You may also request to complete follow-up encounters by telephone. 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. You may visit www.unthsc.edu/PRECISION to see if you qualify to participate in the registry. We look forward to hearing from you.
