The study found no significant differences in the effectiveness of yoga versus PT. But for people without health insurance (or those of us with less-than-great insurance) there could be a significant difference in cost for these two types of treatment. Yoga doesn’t require a doctor’s prescription, and it can be cheaper than PT by an order of magnitude. Or free, even, if you go on Youtube—though that's probably not ideal for someone looking to treat their back pain, at least initially, since poor form might make injuries even worse. But if you're facing tough choices in managing your chronic back pain, consider taking up a chill new hobby to see if it helps. Breathe deeply, and enjoy the sweet feeling of saving money!
