The effect of body mechanics instruction on work performance among young workers.
Thirty young workers ( aged 14 to 19 years ) employed as groundskeepers and custodians were r and omly assigned to two groups ; one group received body mechanics instruction and the other did not . The instruction focused on proper spinal alignment in the work environment . Instruction on  low back pain  began with one classroom session before the subjects ' first day of work and continued during employment with two on-site sessions . The effect of instruction was evaluated through the observation of body mechanics during actual work performance . The results of the study indicate that the group that received instruction performed significantly better than the control group . This paper also discusses the occupational therapist 's role in providing job-specific  body mechanics instruction in the work environment as a primary method of preventing low back pain
