Responsiveness of the PROMIS Global Health-10 Survey compared with the Oswestry Disability Index in patients undergoing 1- and 2-level lumbar fusions

The PROMIS-10 PHT provided similar responsiveness and construct validity as seen with the ODI at detecting functional changes after elective lumbar fusion. The PROMIS-10 MHT provides valuable insight into the patient's current mental health but was not overly responsive to change. The ODI remains the most responsive and accurate tool to assess low back function and postoperative improvement, but the PROMIS-10 can provide additional meaningful data that could be used to augment information gained from the ODI.
