Lumbar supports – you see certainly men on the janitorial staff and men who are moving furniture wearing there lumbar supports. The idea is that they will remind them to lift properly, increase intra-abdominal pressure and decrease intradiscal pressure. All the RCTs are negative. Controlled clinical trials (CCTs) there are some positive ones and they seem to reduce the incidence of LBP or injury. The consensus of the evidence is because all the RCTs are negative, the consensus is that lumbar supports don’t do anything. So that’s nixed.
