Knowledge and use of work-related musculoskeletal disorder (WRMSD) prevention techniques in the daily practice of final-year Australian sonography students: A cross-sectional study

Abstract

Introduction: Work-related musculoskeletal disorders (WRMSD) commonly occur among student and qualified sonographers. While students may be educated about preventative techniques, transfer of this knowledge to practice may not occur. The aim of this study was to investigate the association between the theoretical knowledge final-year students had of some common WRMSD prevention techniques, and the use of these techniques on clinical placement. Methods: A cross-sectional study via anonymous online survey was distributed to Australian sonography students from a single institution completing their final year of clinical placement. Results: There were 31/81 participants equating to a response rate of 42%. Of the 12 sonography WRMSD prevention techniques selected to be part of this study, participants had theoretical knowledge of 11/12 (91.7%) prevention techniques. A significant association was established between the theoretical knowledge of, and the use of 8/11 (72.7%) prevention techniques. Ergonomic adjustment of equipment 29/31 (92.6%) and postural modifications 28/31 (90.3%) were the WRMSD prevention techniques implemented most frequently. No association was found between the theoretical knowledge and use of stretching prior to or between scanning patients, or the use of ergonomic aids for WRMSD prevention. Conclusion: Students were found to have retained ergonomic knowledge, utilising both postural and equipment adjustments during clinical placement. Consistent implementation of WRMSD prevention techniques may reduce students' risk of developing a future WRMSD. Longitudinal research is suggested to ascertain if students continue to implement prevention techniques once qualified.
