Participant Flow

Patients (18 and 60 years) with SLBP (subacute low back pain) (lasting 4-12 weeks) with or without radiculopathy who were assigned to the social security system and living in the metropolitan area were included.

A specific cause for the pain (infection, tumor, ankylosing spondylitis, inflammatory conditions or cauda equine syndrome), the presence of red flags, scoliosis \>15 °, depression or mental illness, history of gastrointestinal bleeding, renal failure, intake of anticoagulants or antiplatelet drugs and NSAID allergy were excluded.

Participant milestones
Measure	Excercise One group will be assigned to protocolized back pain exercise, three times a week for 4 weeks. This program is carried out by physiotherapists from participating institutions who wish to participate in research and who will be given a training which will standardize the intervention programs Exercise program includes: physical agents, massage of myofascial points, stretching and strengthening exercises, cycloergometer or band aerobic exercises. Treatment, type of exercises, exercise tolerance and adverse reactions will be registered Exercise program : Standardize the intervention programs Exercise program includes: physical agents, massage of myofascial points, stretching and strengthening exercises, cycloergometer or band aerobic exercises. 12 sessions, 3 per week.	NSAID Naproxen 500 mg per day by 10 days or Celecoxib 200 mg per day by 10 days and acetaminophen 1,5 a 2 g as rescue NSAID : The second group was treated for 10 days with NSAIDs (naproxen 500 mg/d or celecoxib 200 mg/d) according to the indications and contraindications. The patients kept a journal stating whether they had taken the drug and any adverse reactions. If the pain intensity of any participant increased, acetaminophen (1.5 - 2.0 g/d) was proposed as a rescue procedure.

Function was assessed using the Oswestry Disability Index questionnaire Version 2.1a, which ranges from 0 to 100 (greater disability), being worst 100. The Oswestry Disability Index is currently considered by many as the gold standard for measuring degree of disability and estimating quality of life in a person with low back pain. 0% to 20%: Minimal disability, 21%-40%: Moderate Disability, 41%-60%: Severe Disability, 61%-80%: Crippling back pain, 81%-100%: These patients are either bed-bound or have an exaggeration of their symptoms.

Improvement in function assessed by the Roland-Morris questionnaire, a widely used health status measure for low back pain. The RMDQ can be used in research or clinical practice. Scoring the RMDQ. The RMDQ is scored by adding up the number of items checked by the patient. The score can therefore vary from 0 to 24. It is not recommended to give patients a 'Yes' / 'No' option. If patients indicate in any way that an item is not applicable to them, the item is scored 'No', i.e. the denominator remains 24. Being worst 24.

Improvement in Quality of life was assessed with the SF-36 questionnaire, which ranges from 0 to 100 being 100 the best quality of life. The Short Form (36) Health Survey is a patient-reported survey of patient health. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e. a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability. This outcome shows the subdomain data: change in health.

Improvement in Quality of life was assessed with the SF-36 questionnaire, which ranges from 0 to 100 being 100 the best quality of life. The Short Form (36) Health Survey is a patient-reported survey of patient health. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e. a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability. This outcome shows the subdomain data: change in health.

Measure	NSAID n=44 Participants Naproxen 500 mg per day by 10 days or Celecoxib 200 mg per day by 10 days and Acetaminophen 1,5 a 2 g as rescue NSAID : The second group was treated for 10 days with NSAIDs (naproxen 500 mg/d or celecoxib 200 mg/d) according to the indications and contraindications. The patients kept a journal stating whether they had taken the drug and any adverse reactions. If the pain intensity of any participant increased, acetaminophen (1.5 - 2.0 g/d) was proposed as a rescue procedure.	Excercise n=46 Participants One group will be assigned to protocolized back pain exercise, three times a week for 4 weeks. This program is carried out by physiotherapists from participating institutions who wish to participate in research and who will be given a training which will standardize the intervention programs Exercise program includes: physical agents, massage of myofascial points, stretching and strengthening exercises, cycloergometer or band aerobic exercises. Treatment, type of exercises, exercise tolerance and adverse reactions will be registered Exercise program : Standardize the intervention programs Exercise program includes: physical agents, massage of myofascial points, stretching and strengthening exercises, cycloergometer or band aerobic exercises. 12 sessions, 3 per week.

The patients kept a journal stating whether they had taken the drug and any adverse reactions. If the pain intensity of any participant increased, acetaminophen (1.5 - 2.0 g/d) was proposed as a rescue procedure.	Excercise n=40 Participants One group will be assigned to protocolized back pain exercise, three times a week for 4 weeks. This program is carried out by physiotherapists from participating institutions who wish to participate in research and who will be given a training which will standardize the intervention programs Exercise program includes: physical agents, massage of myofascial points, stretching and strengthening exercises, cycloergometer or band aerobic exercises. Treatment, type of exercises, exercise tolerance and adverse reactions will be registered Exercise program : Standardize the intervention programs Exercise program includes: physical agents, massage of myofascial points, stretching and strengthening exercises, cycloergometer or band aerobic exercises. 12 sessions, 3 per week.

Improvement in Quality of life was assessed with the SF-36 questionnaire, which ranges from 0 to 100 being 100 the best quality of life. The Short Form (36) Health Survey is a patient-reported survey of patient health. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e. a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability. This outcome shows the subdomain data: Physical Function.

SECONDARY outcome

Timeframe: 12 weeks

Population: We lost 4 patients in arm exercise because we ran out of time limit for the investigation and could not evaluate them. And we lost 4 in arm NSAIDs, 3 who did not answer our calls and 1 for close investigation.

Improvement in Quality of life was assessed with the SF-36 questionnaire, which ranges from 0 to 100 being 100 the best quality of life. The Short Form (36) Health Survey is a patient-reported survey of patient health. The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e. a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability. This outcome shows the subdomain data: Mental Health.
