Brief Summary:

Non-specific low back pain is a common condition. Exercise is effective treatment for chronic low back pain. We hypothesized the functional exercise group will present pain reduction and functional improvement.

The purpose of this study is investigated the effectiveness of an functional exercise program for people with nonspecific chronic low back pain. Patients will be randomly divided into 2 groups: control group (minimal intervention - mini back school and analgesic) and group will receive a functional exercise protocol associated with minimal intervention.

Arm Intervention/treatment
Experimental: Functional exercise Other: Functional Exercise Protocol
Functional exercise protocol. This protocol started with corporal conscience exercise, breathing, abdominal activation, activities such as sitting, getting up, climbing stairs, reaching with arms, moving forward, bodyweight exercises, bridges and boards. This protocol will be performed during 12 weeks, two sessions per week.

Other: Minimal
Analgesic use when necessary and a single back scholl class

Active Comparator: Control Group Other: Minimal
Analgesic use when necessary and a single back scholl class

Primary Outcome Measures :
  1. Low back of pain intensity measured with Numeric Pain Rating Scale [ Time Frame: Baseline, 6, 12 and 24 weeks ]
    It will be measured by the Brazilian version of the Numeric Pain Rating Scale (NPRS) 11 points. The NPRS goes from 0 to 10, where 0 is "no pain" and 10 is "the worst pain imaginable." Participants will be asked to answer about their pain levels based on the last seven days. Change in pain score or an improvement of 2 levels or more is accepted as clinically relevant.

Secondary Outcome Measures :
  1. Disability associated to low back pain measured with Oswestry Disability Index [ Time Frame: Baseline, 6, 12 and 24 weeks ]
    Change in Oswestry Disability Index score

  2. Disability associated to low back pain measured with Roland Morris Disability [ Time Frame: Baseline, 6, 12 and 24 weeks ]
    Change in Roland Morris Disability score

  3. Fear of movement measured with Fear-Avoidance Beliefs Questionnaire [ Time Frame: Baseline, 6, 12 and 24 weeks ]
    Change in Fear-Avoidance Beliefs Questionnaire score

  4. Quality of life measured with Short form-36 questionnaire [ Time Frame: Baseline, 6, 12 and 24 weeks ]
    Change in Short form-36 questionnaire score

  5. Function measured with the 6-minute walk test [ Time Frame: Baseline, 6, 12 and 24 weeks ]
    Change in 6-minute walk test

  6. Function measured with the timed to up and go test [ Time Frame: Baseline, 6, 12 and 24 weeks ]
    Change in timed to up and go test

  7. Patient's global impression of recovery measured with a likert scale [ Time Frame: 6, 12 and 24 weeks after baseline ]
    It will be evaluated based on the global perceived effect by the Likert Scale Score. The Likert scale, used to evaluate the patient's global perceived effect with treatment. The patients answered the question 'After starting the treatment, how do you think your low back is?' with one of the following statements: much worse, a little worse, unchanged, a little better, much better.

  8. Analgesic consumption [ Time Frame: 6, 12 and 24 weeks after baseline ]
    Change in analgesic consumption
