There are a lot of different types of back pain. I'm always stunned at how they get lumped together. Lower back muscle ache caused by stress and poor posture is a very different beast from a pinched nerve or a herniated disc or even muscle spasms caused by a glute injury. It makes sense for a psychological component to treatment to be effective for stress-related back pain. And yes, stress can aggravate pain from a physical injury. But there are also plenty of physical injuries that aren't psychosomatic.
