Is there any attempt at making low back pain studies more uniform among researchers?

Yes, one place to start is with definitions. In 2006, a group querried researchers from 12 different countries and came up with two definitions of low back pain. One definition was a minimal definition, the other was an optimal definition to be used in epidemiological studies. The hope is that dissemination and use among researchers will be of benefit when comparing studies on low back pain.
