3. Has a SI joint pain score of at least 5 out of 10 on numerical rating scale at enrollment.
4. Be at least 21 years of age at enrollment
5. The patient's physician has decided that the best treatment for the patient's SIJ dysfunction is the Nevro1 SI Fixation System, and the patient has agreed to the treatment

15. Has a prominent neurologic condition that would interfere with physical therapy
16. Be pregnant or plan on becoming pregnant in the next two years.
17. Has a medical condition or pain in other area(s), not intended to be treated in this study, that could interfere with study procedures, accurate pain reporting, and/or confound evaluation of study endpoints, as determined by the Investigator
