The LTU patients had a mean (SD) overall satisfaction of 8.19 (2.08) on a 10-point scale, with 10 representing excellent. The mean change (based on a 10 point scale) in pain interference with work outside the home was 2.70, with activity inside the home was 3.03, with social activity was 2.79, and with pain relief was 2.47 (p<0.001).
