Back injury prevention interventions in the workplace: an integrative review.

The purpose of this integrative review is to describe the state of knowledge about the effect of worksite back injury prevention programs on selected study outcomes. Fifteen experimental and quasi-experimental studies published between 1987 and 1994 were identified through a comprehensive literature search. The research studies were reviewed and analyzed using a data collection abstracting tool. Four types of back injury prevention intervention programs were identified: back belts, back schools, exercise/flexibility training, and educational classes. Positive program outcomes were reported for all four program types; however, the back school and the exercise/flexibility training programs were studied more frequently and demonstrated a greater proportion of positive results than the other two program types. Conclusions should be viewed cautiously due to the small number of studies reviewed and their methodological limitations. Implications for occupational health nursing practice and future research related to worksite back injury prevention are offered.
