Low back pain is the greatest cause of disability worldwide and associated with great societal and economic burden. Its economic burden is equivalent to the burden of other chronic non-communicable diseases, such as cardiovascular diseases and cancer. Researchers are looking for adults with a current episode of low back pain that is causing moderate interference with their everyday life and who have a mobile phone that can receive text messages.
Participants will be randomised to one of the two groups which will receive different volumes of text messages in different formats. The text messages will provide education and self-management strategies. Participation will involve receiving text messages and completing online surveys.
