Back Pain and Interventions

I ran across this article today on the Usernomics website and thought I would post it and get your comments. The article is states "A Finnish review has concluded that employer attempts to push training programs that offer lifting advice and material handling devices in an effort to alleviate worker back pain do not prevent the malady, which is said to be the top cause of workers' compensation claims." It also states, "According to Maher, regulatory agencies as well as employers make the mistake of concentrating on equipment and policies that don't work such as back belts, lifting devices and workplace re-design and fail to focus on the 'only known effective intervention,' which is exercise. " I have not been able to find the actual review, just this article about the review. This seems to be a controversial claim. Has anyone encountered other research or reviews that suggest otherwise? Note that this study is talking about back pain and not back injury.
