The introduction of the technological age and increasing mechanisation has led to labour-saving devices which have significantly engineered physical activity out of our lives, with sedentary behaviour becoming the default behaviour during waking hours.

The behaviour change technique of self-monitoring has shown promise in interventions to promote healthy lifestyles in adults. There is now a robust set of literature indicating self-monitoring as the most promising behaviour change technique in this area.

Self-monitoring is tied inherently into the recent rise in wearable technology. One such device is the LumoBack Posture sensor which can monitor and provide feedback on time spent sedentary.

As part of the DeSIT (Decreasing sedentary behaviour using innovative technology) study, 42 participants aged 25 or older wore the LumoBack without any feedback for one week for baseline measures of behaviour. Participants then wore the LumoBack for a further five weeks whilst receiving feedback on sedentary behaviour via a sedentary vibration from the device and feedback on the mobile application.

  • Data collection completed: October 2015
  • Data analysis completed: May 2016
  • Journal article and report written up as part of a doctoral thesis: October 2016
  • Unfortunately there were no statistically significant differences in behaviour between baseline and the LumoBack intervention period. Participants engaged most with the steps on the LumoBack app with peaks in engagement seen at week five.
