The trials suggest that work place exercise is effective , braces and education are ineffective , and workplace modification plus education is of unknown value in preventing low back pain
A systematic review of r and omised controlled trials was undertaken to evaluate the effectiveness of  workplace interventions  to prevent low back pain .
Comparison of classroom instruction and independent study in body mechanics.
This study was design ed to determine which method of instruction in body mechanics results in the higher subsequent use of the techniques taught . Two groups were formed from nursing personnel at a rural general medical-surgical hospital in the southwestern United States . Subjects from the direct care nursing staff were r and omly assigned to one of the two groups . One group attended two hours of classroom instruction in body mechanics , while the other completed an independent study module . Subjects were pre- and posttested using the Work-Related Body Mechanics Evaluation ( Carlton , 1987 ) while performing a st and ardized lifting task in the clinical setting . Using analysis of covariance , no significant differences were found in the posttest scores of the two groups
