Outcome Measures
Primary Outcomes (1)
Disability score as assessed by the Roland-Morris Disability Questionnaire
Disability will be the primary clinical outcome and will be measured using the Brazilian-portuguese validated version of the Roland-Morris Disability Questionnaire (RMDQ). The questionnaire consists of 24 items with 0=no and 1=yes, and the total score ranges from zero (no disability) to 24 (severe disability).
From enrollment to the end of treatment (around eight to ten weeks from baseline), and follow-up moments: follow-up 1 (26 weeks after baseline); follow-up 2 (39 weeks after baseline), and follow-up 3 (52 weeks after baseline)
Secondary Outcomes (5)
Pain intensity as measured using the Numerical Rating Scale (NRS)
From enrollment to the end of treatment (around eight to ten weeks from baseline), and follow-up moments: follow-up 1 (26 weeks after baseline); follow-up 2 (39 weeks after baseline), and follow-up 3 (52 weeks after baseline)
Health-related quality of life (Utility) as measured by the EuroQol-5 Dimensions-5 Levels (EQ-5D-5L) questionnaire
From enrollment to the end of treatment (around eight to ten weeks from baseline), and follow-up moments: follow-up 1 (26 weeks after baseline); follow-up 2 (39 weeks after baseline), and follow-up 3 (52 weeks after baseline)
Fear and beliefs as measured by the Fear Avoidance Beliefs Questionnaire
From enrollment to the end of treatment (around eight to ten weeks from baseline), and follow-up moments: follow-up 1 (26 weeks after baseline); follow-up 2 (39 weeks after baseline), and follow-up 3 (52 weeks after baseline)
Self-efficacy as measured by the Self-Efficacy Questionnaire (PSEQ)
From enrollment to the end of treatment (around eight to ten weeks from baseline), and follow-up moments: follow-up 1 (26 weeks after baseline); follow-up 2 (39 weeks after baseline), and follow-up 3 (52 weeks after baseline)
Perceived recovery as measured by the Global Perceived Effect Scale
At the end of treatment (around eight to ten weeks from baseline), and follow-up moments: follow-up 1 (26 weeks after baseline); follow-up 2 (39 weeks after baseline), and follow-up 3 (52 weeks after baseline)
Other Outcomes (2)
Quality-adjusted life years (QALY)
From enrollment to the end of treatment (around eight to ten weeks from baseline), and follow-up moments: follow-up 1 (26 weeks after baseline); follow-up 2 (39 weeks after baseline), and follow-up 3 (52 weeks after baseline)
Cost-effectiveness
From enrollment to the end of treatment (around eight to ten weeks from baseline), and follow-up moments: follow-up 1 (26 weeks after baseline); follow-up 2 (39 weeks after baseline), and follow-up 3 (52 weeks after baseline)
Study Arms (2)
mhealth application (experimental group)
EXPERIMENTALThe mhealth intervention group will be instructed to perform the exercises twice a week for 8 weeks, lasting approximately 30 minutes per session. Participants will be instructed to watch the health education content (e.g., short videos, infographics) and exercise videos provided by the app, and to take breaks during each session. Guidance will be provided during the intervention and weekly monitoring by a physiotherapist by messaging or telephone calls. In the first week of the intervention there will be two face-to-face sessions supervised by the physiotherapist to familiarize the participants with the mobile application and provide instructions on the intervention. A further face-to-face session will take place half-way the intervention, to monitor the participants.
Conventional booklet exercise (comparator group)
ACTIVE COMPARATORAfter the assessment, all participants will receive a printed booklet containing a description and recommendations for carrying out the exercise program at home, which will be characterized by general exercises (i.e., strengthening, mobilization). The individuals will be instructed to perform the exercises twice a week for 8 weeks, following the same duration on the experimental group. Participants will be monitored and supervised by another physiotherapist via messaging app or telephone calls, following the same procedures reported in the experimental group. In the first week of the intervention there will be two face-to-face sessions supervised by a physiotherapist to familiarize the participants with the exercises and explain the booklet, and provide instructions on the intervention. A further face-to-face session will take place half-way the intervention, to monitor the participants.
Interventions
Individuals enrolled in the mhealth intervention will receive tailored content will include exercises focused on mobility, flexibility, core stabilization, and strengthening. Additionally, the mobile application will provide educational material on pain and health, covering topics such as the neurophysiology of pain, the multidimensional nature of low back pain, myths and facts about the condition, the importance of sleep, and stress management, which will include relaxation techniques and mindfulness. All content will be evidence-based, using clinical guidelines, systematic reviews and other high-quality studies to support inclusion in the mobile application. The intervention will be supervised by a physiotherapist, remotely via messaging or telephone calls.

- Masking Details
- Blinding the therapists will not be possible due to the nature of the interventions. Because outcomes are self-reported, blinding participants to the intervention will also not be possible. However, an assessor who will be unaware of the group allocation will perform the data collection. The researcher responsible for the statistical analysis will also be blinded to the group allocation (i.e. they will receive the data sheet with the groups/individuals coded numerically).
