SEATTLE, Feb 23, 2009 (UPI via COMTEX) -- A systematic review of studies found
exercise in workplace and community settings is effective in preventing low-back
problems, U.S. researchers said.
"Strong and consistent evidence finds many popular prevention methods to fail
while exercise has a significant impact, both in terms of preventing symptoms
and reducing back pain-related work loss," Dr. Stanley J. Bigos, a University of
Washington professor emeritus of orthopaedic surgery and environmental health,
said in a statement.
"Passive interventions such as lumbar belts and shoe inserts do not appear to
work and eight trials found ergonomic interventions, of either reducing lifting,
or back or ergonomic training sessions to be ineffective in preventing back
problems."
Bigos and colleagues assessed methodological quality and potential for bias of
clinical trials in preventing episodes of back problems.
The review, published in The Spine Journal, found 20 controlled trials to be
high-quality and seven of the eight high-quality trials promoting various
exercise programs were found effective, but other common and popular methods
failed including: reduced lifting programs, back or ergonomic educational
interventions, lumbar supports, shoe inserts and stress management.
However, review co-author Dr. John Holland said the review does not discredit
popular ergonomic innovations, which may increase productivity, product quality
and work comfort and there are many reasons why such research should continue.
