[Risks of repetitive movements in health personnel]

Abstract

To date, scant attention has been devoted to the occupational risk related to repetitive movements in health personnel. Using three database, PubMed, Scopus, and EMBASE, we found 57 papers on this topic, and on possibly related upper limb symptoms and diseases. In these studies, evaluation of the risk, e.g. using the methods currently applied in industry, are lacking. Although in several studies data on the prevalence of upper limb symptoms and disorders are presented, a comparison of results is difficult as different methods were applied. Furthermore, a comparison with adequate controls is frequently lacking, and/or correlation with the risk was not studied. Despite these limitations, an overall evaluation of the results shows that in health personnel the prevalence of upper limb symptoms/disorders is generally high. Highest prevalences were observed for the neck, shoulder, wrist/hand symptoms and for Carpal Tunnel Syndrome (CTS) in dental personnel, for symptoms to the neck, shoulder and wrist/hand in sonographers, and to the neck, shoulder, elbow, and, especially, wrist/hand in laboratory technicians using manual pipettes. In the nursing personnel highly variable prevalences were observed; this is possibly due to the variability of the tasks performed by this occupational group. Repetitive movements of upper limb are a known risk factor for symptoms to the neck, shoulder, elbow, and wrist/hand, and some disorders, as CTS: the high prevalences observed in health workers may be related to this risk. Nevertheless, other factors such as effort, posture and precision work may play an important role too. As a conclusion, available data are insufficient for an adequate evaluation of the occupational risk related to repetitive movements in health workers.
