Anecdotal evidence but this improved my lower back pain issues. I was sitting at a desk for many hours a day and didn't really work out. I started by sitting on a stability ball for 10minutes, this allowed me to focus on my posture and would give my muscles time to adjust. I gradually increased the time. It's obviously not as comfortable as a chair and maybe that is also one of its big advantages since it forces you to take a break more often. This was a while ago but I don't think I ever sat exclusively on a ball, it was maybe an hour to three hours a day at the most. Nowadays I don't have any lower back issues anymore and I regularly exercise, which obviously is much better than symptom treatment by sitting on a ball. YMMV
