Intervention model description: A randomized controlled double-blind clinical trial, with a 1:1 allocation of 102 participants divided into two groups (intervention or control).
Primary purpose: TREATMENT

Brief summary: The goal of this study is to measure the effect of telerehabilitation on the treatment of nonspecific chronic LBP in the adults Brazilian Black population. The main questions it aims to answer are:

1. Will the graded activity exercises guided by educational approach or only the educational approach alone improve low back pain intensity, functional capacity, quality of life, anxiety, fear-avoidance beliefs due to nonspecific chronic low back pain before, immediately after the 4-week intervention, and after 3 and 6 months of follow-up?
2. How will participants' behaviors in terms of frequency and adherence, exercise feedback diary, and educational approach for nonspecific chronic low back pain be?

   What are the participants' opinions and any difficulties or barriers encountered throughout the study?
3. What are the perceptions of discrimination based on race, gender, age, socioeconomic status, and education when accessing healthcare services for the treatment of low back pain in the past?

Researchers will compare Group Experimental Graded Activity with Educational Program with Telerehabilitation to a placebo (only Educational Approach ) to see improve the pain intensity and functional capacity because of low back pain.

Participants will:

* Take Group Experimental (GAEP) or a placebo (OEA) 3 times per week, for 1 month.
* Keep a feedback diary of their symptoms and the barriers they have.
* Visit the researcher by online teleassessment after one month, 3 months and 6 months follow-up.

Detailed description: Background: Low back pain (LBP) is highly prevalent, ranging from 30 to 70% in developed and industrialized countries, leading to health costs and work absenteeism. However, when it comes to the Black population, studies addressing the treatment of nonspecific chronic LBP while considering the specificities of this population are scarce. The use of telerehabilitation opens up opportunities for the physiotherapy community to address musculoskeletal conditions.

The goal of this study is to measure the effect of telerehabilitation on the treatment of nonspecific chronic LBP in the adult Brazilian Black population.

Methods: A randomized controlled double-blind clinical trial, with a 1:1 allocation of 102 Afro-Brazilian participants divided into two groups, with 51 participants in each, experiencing nonspecific chronic LBP for at least 3 months, of both sexes, aged 18-65 years, residing in Brazil, and divided into the Gradual Activity Group (GAG) and Control Group (CG), with a duration of 12 sessions, three times per week. The intervention will involve the adaptation of an exercise program protocol based on gradual activity with progressive exercise intensity, through the web applications Physitrack® (researcher) and Physiapp® (participant). Sociodemographic and clinical characteristics will be evaluated. The primary outcome will be pain intensity, and secondary outcomes will include functional capacity, quality of life, beliefs, and fears. Also the perceptions of discrimination based on race, gender, age, socioeconomic status, and education will be assessed regarding prior access to healthcare services for the treatment of LBP. The groups will be assessed at baseline (T0), immediately post-treatment (T1), at 3-months (T2) and 6-months (T3) follow-ups. Data will be collected and managed using the REDCap® electronic data capture tools.

Discussion: Evidence suggests that telerehabilitation can be utilized as a potential tool to promote the treatment of non-severe conditions of nonspecific chronic LBP, but few studies have investigated the Black population while considering the specificities of populations that historically suffer from social inequalities in accessing healthcare treatments.
