Background: Low back pain is a major problem for public health that affects about 60-85% of the population at some point in life. Approximately 10-40% of individuals with low back pain develop the chronic form. International guidelines consider three groups of treatment options for low back pain: medication, invasive and conservative treatments in which conservative approach is the most recommended. The European Guidelines for Management of Chronic Non-specific Low Back Pain recommends that supervised exercise programs should be used as front-line treatment for chronic low back pain, such as stabilization exercises, conventional stretching and other active exercise, but there is no consensus on literature on the most effective form of treatment. However, there is limited evidence about the effects of a global stretching intervention using self-stretching postures for chronic low back pain.
Objectives: The aim of this research is to compare the effects of an active global stretching program (GSP) using self-management of posture versus stabilization exercises on pain intensity and disability for patients with chronic non-specific low back pain.
Methods: This study is a randomized controlled three arm clinical trial with examiner blinding. A sample of 100 patients with chronic non-specific low back pain will be randomly assigned to two treatment groups (GSP or Stabilization Exercises). The eligibility criteria will be 18 and 50 years, pain in the last three months and/or pain in at least half of the days in the past six months, pain located between T12 and the gluteal folds, pain intensity greater than or equal to three, and score greater than 14% on Oswestry Disability Index. Patients will be assessed in baseline, immediately after treatment and after one and three-months follow-up. Sessions will be provided weekly for eight weeks by a single therapist lasting 40 minutes. The primary outcomes will be pain intensity and low back pain related disability and the secondary outcomes will be fear avoidance, global perceived effect of treatment and muscle flexibility. All statistical analysis will be conducted following principles of intention to treat, and the treatment effects will be calculated using linear mixed models.

Experimental: Global Stretching Program (GSP)
Participants will be submitted to a GSP in self-management postures weekly for 40 minutes session conducted by one one physical therapist, certified to use the technique (Stretching Global Active).
Procedure: Global Stretching Program
Participants will be submitted to a GSP in self-management postures weekly for 40 minutes session conducted by one one physical therapist, certified to use the technique (Stretching Global Active). The GSP will last for a period of 8 weeks. The protocol is based on the study of Lawand et al (2015) who used all postures global therapeutic stretching. The investigators will use six self-management postures in a standardized manner, each of which will last for 10 to 20 minutes.
Active Comparator: Stabilization Exercises
A exercise protocol will be administered and the criteria to increase exercise progression was previously described by Hicks et al (2005).
Procedure: Stabilization Exercises
The exercise protocol and criteria to increase exercise progression was previously described by Hicks et al (2005). It will be directed by a single therapist one to one session based on specific criteria (being able to maintain muscle contraction eight seconds during 30 repetitions in bilateral exercises or during 20 repetitions for unilateral exercises). Each session will be conducted weekly for 40 minutes.
- Pain Intensity [ Time Frame: Immediately after ]The pain intensity measurement will be accomplished by application of a numerical pain rating scale - NPRS which consists of a sequence of eleven numbers from 0 to 10, in which 0 represents "no pain" and 10 represents "worst pain imaginable". Volunteers will rate their pain based on these parameters.
- Low Back Pain related-Disability [ Time Frame: Immediately after ]To assess disability related to chronic low back pain, the Oswestry Low Back Disability Index - ODI, adapted to Brazilian Portuguese will be used. The result is converted into a percentage by multiplying the total score by two. This instrument consists of 10 items, each of which has six response options. The total score will be calculated by summing up the points, the largest possible sum being #50. Previous research has found ODI showed responsiveness to change for patients with CLBP.
- Fear avoidance beliefs questionnaire (FABQ) [ Time Frame: Immediately after ]The FABQ adapted for Brazilian Portuguese, consists of 16 self- response items, rated on a seven-point Likert scale from 0 (completely disagree) to 6 (completely agree). The score is obtained for each separate subscale: one that addressed the fears and beliefs of individuals in relation to work and one that addressed their fears and beliefs about physical activities.
- Global Perceived Effect of Treatment [ Time Frame: Immediately after ]Global Perceived Effect of Treatment is recommended for use in clinical trials of chronic pain as a measure of the perception of global improvement/worsening regarding to treatment. Global Perceived Effect of Treatment is an 11-point scale that ranges from -5 ("vastly worse") through 0 ("no change") to +5 ("completely recovered"). A higher score indicates higher recovery from the condition.
- Fingertip-to-Floor Test [ Time Frame: Immediately after ]The Fingertip-to-floor test showed excellent levels of validity compared to the radiological measurement (r=0.96) and reproducibility (intra and interexaminer - ICC = 0.99). The test is known for full mobility in the tilted forward position when standing, corresponding to flexion of the spine and pelvis. It is a measure of relevance in rehabilitation results probably because patients simultaneously increase the pelvic and lumbar flexion post treatment.
