Improvement in postoperative and nonoperative spinal patients on a self-report measure of disability: the Spinal Function Sort (SFS).

The present study was designed to evaluate the clinical utility of the Spinal Function Sort (SFS), in a group of postoperative and nonoperative low back pain patients who completed a functional restoration program. The SFS was administered to 38 spinal pain patients (16 nonoperative and 21 postoperative), before and after completing a functional restoration program. Results revealed that the SFS detected a significant improvement in Ratings of Perceived Capacity scores, and that the postoperative patients appeared to improve more than nonoperative patients.
