Studio longitudinale per la valutazione dell'efficacia di misure preventive in una popolazione di operatori sanitari esposta al rischio di movimentazione manuale di pazienti

Preliminary data of a follow-up study on effectiveness of mechanical devices for patients handling are shown. Main study results highlight a statistical significant decrease for subjective referred episodes of acute low back pain during the previous 12 months, a decrease in perceived effort and Borg scale score in the subgroup who received any sort of mechanical devices. However no difference was found regarding to proportion of subjects positive at symptom questionnaire for low back pain and mean length of absenteeism for disease was similar even after the introduction of mechanical devices.
