The effect of body mechanics education on the work performance of fruit warehouse workers

Agriculture is one of the nation's more hazardous occupations, and injury prevention among agricultural workers is a focus of safety and education programs nationwide. This research project investigated the effectiveness of a culturally appropriate body mechanics education program for fruit warehouse workers in Washington State. The purpose of the body mechanics education program was to promote correct ergonomic behavior among migrant and seasonal fruit warehouse workers. Participants received instruction in proper body mechanics by viewing a videotaped Spanish-language theatre program (with English subtitles) followed by a demonstration and practice of correct lifting techniques and selected stretches for injury prevention. A written pre- and post-test to assess body mechanics knowledge and an evaluation of lifting methods were administered at the time of the training and again two weeks later. The results indicated culturally appropriate body mechanics education is an effective intervention for increasing knowledge and promoting correct lifting techniques. However, further research is indicated to examine the significance of supervised and individualized, job-specific practice on affecting more lasting changes in work-related body mechanics and lifting behaviors.
