Introduction and objectives: Even if work musculo-skeletal disorders represent a serious and commonly observed health problem among health care workers, few data are available about physical therapists. This study aims to compare the musculoskeletal disorders prevalence over two different health care populations and
Materials and methods: Two populations have been studied: (i) 100 nurses working in the teaching hospital Azienda Policlinico di Modena and (ii) 100 physical therapists working in different hospitals in Modena and Reggio Emilia. The ergonomic risk assessment has been made according to the Ergo Web questionnaire. A self-reported questionnaire [partly built according to Outil de Repérage et d'Evaluation des Gestes (OREGE) method] has been used to collect data about physiological factors, musculo-skeletal symptoms of the upper limb and spine, stress indexes and psychosocial indexes.
Results: The two populations are comparable as far as the data of physiological and working anamnesis. The physical therapists have an higher prevalence of neck pain (p<0.01), whereas the nurses have an higher prevalence of low back pain (p<0.01). Furthermore, the physical therapists have an higher index of pain (involving prevalence, number of occurrences and intensity of the disorder) of right upper limb too. The nurses have higher working strain (p=0.00), attention need at work (p=0.00), poor autonomy (p<0.01) indexes than physical therapists. The indexes' analysis shows that musculo-skeletal disorders are associated to stress and psychosocial factors in both populations.
