Secondary Outcome Measures:
  • Roland-Morris Disability Questionnaire (RM) [ Time Frame: days 0, 3, 7, 14, 21 and 28 ]

    Secondary outcomes includes the Roland-Morris Disability Questionnaire (RM) for the assessment of functional capacity, with 24 items on low-back pain: higher scores denote poorer functional capacity.

    0: better functional capacity 24: poorer functional capacity Range of score: the highest is 24 (poorer functional capacity) and lowest scores is 0 (better functional capacity).

  • Quality of Life Assessed on the SF-36 [ Time Frame: Days 0, 3, 7, 14, 21 and 28 ]
    Questionnaire Short-form-36 is a widely used generic health status questionnaire, validated for Portuguese with eight components and each components with scores from 0 to 100: higher scores denote greater quality of life.

  • Likert Improvement Assessment Scale [ Time Frame: Days 0, 3, 7, 14 and 21 ]
    Likert improvement assessment scale is based on the patient's opinion (LIKERT P) and assessor's opinion (LIKERT A), categorized in 1=MB (much better), 2=SB (slightly better), 3=NC (no change), 4=SW (slightly worse) and 5=MW (much worse). This scale was was applied to each day of assessment. The numbers in the category titles represent the different days.

  • Number of Anti-inflammatory Tablets Taken [ Time Frame: Days 3,7,14,21 and 28 ]
    Number of 50 mg sodium diclofenac pills taken per day
