Effectiveness of lifting technique training

Lifting technique training continues to be used as a primary way to control manual task risks in the workplace. However, the research evidence shows that providing lifting technique training is not effective in minimising the risk of injury from manual tasks.

The main reason lifting technique training is not effective is because the risk factors causing the problem are not changed. Even if workers attempt to apply ‘safe lifting’ techniques, they may still be exposed to a serious injury risk

The evidence

The Cochrane Collaboration

The Cochrane Collaboration conducted a systematic review in 2011 to determine the effectiveness of manual handling advice and training and the use of assistive devices in preventing and treating back pain in workers.

Cochrane found moderate evidence to prove manual handling advice and training is no more effective at preventing back pain related disability than having no intervention.

No.: CD005958. doi:10.1002/14651858.CD005958.pub3

British Medical Journal

In 2008, research published in the British Medical Journal, concluded 'there is no evidence to support use of advice or training in working techniques for preventing back pain or consequent disability'.

The training interventions that were studied focused on lifting techniques, with training duration varying from a single session to training once a week for two years.

Postal workers study

In this study, approximately 4000 US postal workers were involved in a randomised control trial* for more than five years from 1985 to 1990, to test the effectiveness of manual handling training.

The study included workers and supervisors being taught principles of back safety, core lifting and handling posture, exercises and pain management. A refresher training session occurred six months later and then on a yearly basis.

The study concluded that:

  • the training program did not reduce the rate of lower back injury
  • there was no significant difference in the median cost per injury
  • there was no difference in the rate of musculoskeletal disorders or handling behaviours.

Half way through the study, a survey was conducted to measure knowledge gained and behaviour changes made by the group. The survey found significant increases in the knowledge of safe lifting behaviour among workers, but no significant improvement in actual lifting behaviour or reduction in reported discomfort.
