Effectiveness of a lumbo-pelvic monitor and feedback device to change postural behaviour in healthcare workers

Postural data will be recorded, and audio-feedback provided through a postural monitor feedback device. This device consists of a tri-axial accelerometer and data recorder, and has the size of a pager. Data will be collected over a 6 week period and then at follow-up time points. During the first and sixth week, baseline and post-intervention measurements will be collected. The intervention period consists of 4 weeks (weeks 2 to 5, inclusive). Arm 1 - Feedback Group (FG) The FG will received postural audio-feedback, whenever the postural threshold is exceeded, during the four weeks of intervention. The field coordinator will be responsible for setting the devices and handing these to healthcare workers at the beginning of every week. Participants will wear the device clipped to their waistband or belt, during working hours, over the working days of each week. To enhance adherence, workers will receive reminders to their mobile phones (if they consent with that), and reminders will be printed and placed at strategic areas of the workplace. Adherence will be assessed as the number of days participants worked with the lumbopelvic monitor and feedback device, and was will be expressed as a percentage of total working days of that specific week.
