There was no evidence for the effectiveness of lumbar supports due to contradictory outcomes of the studies .
Thus there is limited evidence that education does not help to prevent back pain .
All three studies on exercise reported a positive result , indicating limited evidence for the effectiveness of exercise .
The review showed that there is limited evidence that exercise has some effect in the prevention of back pain and that education is not effective .
No conclusive evidence was found for or against the effectiveness of lumbar supports .
OBJECTIVE : To assess the effectiveness of lumbar supports , education , and exercise in the prevention of back pain in industry .
Physiotherapy exercises and back pain: a blinded review.
OBJECTIVE --To determine the quality of r and omised controlled trials of exercise therapy for back pain . DESIGN --Computer aided search of published papers and blinded assessment of the methods of studies . SUBJECTS--23 r and omised controlled trials , of which 16 studied exercise therapy given by physiotherapists to individual patients with back pain . Other conservative treatments could be included . MAIN OUTCOME MEASURES --Score for quality of methods ( based on four main categories : study population , interventions , measurement of effect , and data presentation and analysis ) and main conclusion of author(s ) with regard to exercise therapy . RESULTS --Only four studies scored more than 50 points ( maximum 100 ) , indicating that most were of poor quality . Six studies found that exercise was better than reference treatments and 10 reported it to be no better or worse than the reference treatment . Those reporting positive results tended to have higher methods scores ( 4/6 positive v 4/10 negative scored greater than or equal to 42 ) . CONCLUSIONS --No conclusion can be drawn about whether exercise therapy is better than other conservative treatments for back pain or whether a specific type of exercise is more effective . Further trials are needed in which greater attention is paid to methods of study
