Importance The use of spinal cord stimulation for chronic pain after lumbar spine surgery is increasing, yet rigorous evidence of its efficacy is lacking.

The mean score at baseline was 44.7 points and the mean score changes were −10.6 points (95% CI, −14.1 to −7.2 points) for burst stimulation and −9.3 points (95% CI, −12.7 to −5.9 points) for placebo stimulation. Of these 180 treatment periods, follow-up scores were available for 178. Among the 47 patients who underwent randomization and had at least 1 follow-up score, there were 91 burst stimulation periods and 89 placebo stimulation periods. Among the 50 patients who were randomized, 2 patients allocated to burst stimulation and 1 allocated to placebo stimulation did not have follow-up scores starting at 3 months. Each bar extends from a patient’s baseline score to their mean score at the end of the treatment allocation periods. The minimal clinically important difference was 10 points. Scores greater than 40 indicate severe disability. Oswestry Disability Index scores range from 0 points (no disability) to 100 points (maximum disability).
