However, the long-term adherence to regular home exercise is often poor. We aim to perform a prospective, controlled, pilot, randomised study that will evaluate the impact of a smartphone application on adherence to exercise programme for people with chronic LBP (CLBP).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and analysis<\/jats:title><jats:p>120 participants with non-specific CLBP aged 18\u201365 years will be recruited and randomised in two groups: an experimental group benefitting from education in the application\u2019s use in addition to a conventional multidisciplinary rehabilitation programme (exercises and self-management education) and a control group who will only participate in the multidisciplinary rehabilitation programme. Both groups will undergo the programme 5\u2009days a week for 3 weeks. The primary outcome will be a change in patient\u2019s adherence to physical exercise (Exercise Adherence Rating Scale) at 6 months. Secondary outcomes will be function (Oswestry Disability Index), beliefs concerning physical activity (Evaluation of Physical Activity Perception), pain (Numeric Rating Scale), and physical capacity and qualitative adherence (video).<\/jats:p><jats:p>Statistical analyses will be performed according to intention to treat. A linear mixed model will be used to compare the primary endpoint between groups at 6 months post-randomisation.<\/jats:p><jats:p>The study could demonstrate the impact of using a smartphone application on adherence to exercise programme in people with CLBP.
