A questionnaire (including the Nordic Musculoskeletal Questionnaire [NMQ] and the QWL questionnaire) and direct observations of working postures using the Rapid Entire Body Assessment (REBA) method were used. A high prevalence of MSP, particularly in the low back (61.9%), knees (60.5%), ankles/feet (55.8%) and neck (44.9%) were found. The overall mean REBA score of 7.7 suggested that most OR nurses (with posture assessed at action levels 3 and 4) needed an immediate investigation and changes in their working habits and workstations to reduce the risk level. Work-related factors including type of operating room, work shifts (rotating), feeling pressure due to work, total QWL and its dimensions (particularly health and safety, knowledge and esteem needs) and working postures were associated with the presence of MSP in different body regions. Socio-demographic factors including gender (being female) and little or no involvement in sport/physical activity were also independently associated with the occurrence of complaints. The findings emphasise the need for multiple component ergonomic interventions involving the socio-demographic and work-related physical and psychosocial factors for prevention of MSP in this occupational group.enacceso restringidoEngineering, IndustrialErgonomicsHuman Factors And ErgonomicsPublic Health, Environmental And Occupational Healtharticle
