Many studies have been done and are ongoing for back injury and chronic back pain. These studies are so prevalent because back injuries are becoming increasingly common in our society. However, many treatments for back injuries do not work for all or some may work, but not for long periods of time.
The goal of the research is to find the optimal, or best, types of treatment depending on the back injury. Unfortunately, much of this requires trial and error, so what may seem like a promising treatment, may end up not being helpful after all.
