The PNE will follow the principles established by Explain Pain, addressing reconceptualization of pain, emphasizing modern neuroscience concepts. The PNE workshop will last 40 minutes (2 sessions). The movement control exercises will consist of active exercises that address posture and control of movements which are impaired and trigger pain. The session will last approximately 30 minutes, starting with the execution of the coordination exercises in the control of movement with an intensity of 10 to 30 repetitions and then performing exercises for stretching in 3 series of 30 seconds. Finally, strengthening exercises in 3 sets of 15 repetitions will be implemented. The exercises will be administered 1 session/week (volunteers will be oriented to execute the same exercises at home twice a week). The volunteers will receive 8 sessions at the clinic.

The Self-Management Education (SME) strategy will be aligned with the "Back Book" concepts, focused on behavior change and encouraging participants to be active despite of the pain. The SME workshop will last 40 minutes (2 sessions). The movement control exercises will consist of active exercises that address posture and control of movements which are impaired and trigger pain. The session will last approximately 30 minutes, starting with the execution of the coordination exercises in the control of movement with an intensity of 10 to 30 repetitions and then performing exercises for stretching in 3 series of 30 seconds. Finally, strengthening exercises in 3 sets of 15 repetitions will be implemented. The exercises will be administered 1 session/week (volunteers will be oriented to execute the same exercises at home twice a week). The volunteers will receive 8 sessions at the clinic.

Pain neuroscience education (2 sessions during 40 minutes) administered by an interactive workshop

The NPRS used to assess pain intensity in this trial will consist in a sequence of numbers from 0 to 10, in which 0 represents "no pain" and 10 represents "worst pain imaginable". Previous research has found the NPRS to be responsive to change, with a minimum clinically important difference (MCID) of 2.4 among patients with CLBP receiving exercise or education.

The Brazilian Portuguese version of Oswestry Disability Index (ODI) will be used to assess low back pain related disability. This instrument consists of 10 items, each of which has six response options. The total score will be calculated by summing up all the points, with the largest possible sum being 50. This sum will be transformed into a percentage by multiplying it by two. Previous research has found that ODI showed responsiveness to change for patients with CLBP, with MCID of 8 points.

Validated and translated to Brazilian-Portuguese, the Pain Catastrophizing scale (Br-PCS) is a self-administered questionnaire that presents 13 questions, divided into 3 domains: helplessness, magnification, and rumination. The scale has 5 points: 0 (minimum); 1 (slight); 2 (moderate); 3 (intense); and 4 (very intense). The final score ranges from 0 to 52 points, with the psychological risk being directly proportional to higher scores.
