Lay summary
Despite ergonomic training, healthcare workers are exposed to repetitive and sustained flexed posture, increasing the risk of developing low back pain (LBP). This study will assess the effectiveness of a postural monitor and feedback device for modifying postural behaviour in healthcare workers. Our previous research has shown this device to be a reliable and valid instrument for measuring posture at work. Results from the feasibility trial suggested healthcare workers, exposed to audio-feedback training delivered over a 4-week period, reduced the amount of time spent in excessively flexed posture. For this study, workers from healthcare organisations around Otago and Southland will be recruited. Participants will be randomly allocated to one of the two intervention arms: control or feedback group. Results from this study will have community benefit by minimising hazardous postural exposure and potentially reducing the risk of development of LBP in workers.
