Low back pain (LBP) and shoulder and arm disorders are common among workers exposed to risk due to manual weight lifting, and this health care problem is also very costly. We also know that nursing personnel exposed to manual patient handling activity report high number of work-related musculoskeletal disorders. The objective of our study was to evaluate the relationships between work and musculoskeletal disorders in personnel exposed to manual patient handling activity. 160 health care workers of an hospice exposed to patient handling were compared to a control group of 172 people not exposed to the handling risk. In our study we considered only subject with pathology already diagnosed, withdrawing people with disturbs but without clinical trials. The statistical evaluation using the chi2 test has not shown any meaning in the comparison between the two groups, we have calculated the Odds Ratio risk for discal hernia and protrusion finding a risk between low and modest (1.52). We think that the least prevalence of musculoskeletal disorders to the back in the group exposed to manual patient handling activity, could be explained partly with the "healthy worker" effect and partly with the workplace improvement. That is demonstrated also with the M.A.P.O. index scoring between 0 and 1.5 (negligible risk).
