Back Pain Not Prevented By Instructing People How To Lift Heavy Objects
According to a study published on bmj.com, back injuries are not prevented by telling people the correct way to lift heavy objects.
Back pain can be the cause of much distress and is a common complaint
among workers involved with lifting heavy objects. Employers in the
United Kingdom must be sure to provide
training that advises workers on specific lifting techniques and on how
to handle heavy loads correctly. However, this recent meta-analysis
finds no evidence that the training and advice given to workers
has any effect.
The research team analyzed eleven studies with the following properties.
Eight studies focused on health workers who
handled lifting patients
Three studies followed baggage handlers and postal workers
All participants worked at jobs that strained the back
All participants could potentially lessen strain through
proper training
No participants were actively treating current back
pain
After evaluating the eleven studies, the researchers found no
difference in back pain when comparing groups who received training and
groups who did not. When comparing a group that received training and a
group that received a less-extensive video to watch on pack pain, there
was no effect on back pain noted. One trial concluded that there was no
significant difference in reported back pain between a group that
received training and a group that received back belts. No significant
difference was found between groups that received training versus
physical exercise. In another trial, there was no difference in back
pain when comparing a group that received nothing and one that received
training and an assistive device.
Explaining their findings, the researchers suggest that workers do not
really change their habits for training to have an impact or the
techniques taught in training do not actually reduce the potential for
back injury. They propose that new ways of preventing back pain due to
lifting can be the result of more research on how the back responds to
stress at work and the development of back pain.
The article is accompanied by an editorial written by Niels Wedderkopp,
an Associate Professor at the Back Research Center in Ringe, Denmark.
He suggests that the best way for some people to deal with back pain is
to change jobs and carefully stay active in daily life in order to
"regain command of their back and their occupation." He also warns that
advice to stay active may not be the optimal for people whose work
involves heavy lifting.
