Prognostic Factors of Disabling Low Back Pain in Patients With Chronic Low Back Pain

May 26, 2015 updated by: Martin Descarreaux, Université du Québec à Trois-Rivières

Risk of Poor Prognosis in Patients With Chronic Low Back Pain : Can it be Predicted by Physical Tests and Screening Tools ? - An Observational Study

The aim of the present study is to quantify the relative contribution of variables obtained during a physical fitness evaluation and a short screening questionnaire in determining the short-term and long term risk of persistent disabling low back pain in patients with chronic low back pain. It has been hypothesized that patients with higher physical fitness will present a lower risk of persistent disabling low back pain and so, a lower score on the questionnaire.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 60 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

volunteer with chronic nonspecific low back pain will be recruited among the university's community, its outpatients' chiropractic clinic and through advertisements in the local newspaper. They will first be screened by clinicians at the outpatients' chiropractic clinic in order to assess for the various inclusion and exclusion criteria.

Description

Inclusion Criteria:

  • adults between 18 and 60 years old
  • nonspecific low back pain : pain located between the twelfth rib and the inferior gluteal fold for which no specific source of pain could be identified
  • chronic low back pain : pain present for 12 weeks or more, and included both constant and recurrent patterns of pain
  • able to read and understand French

Exclusion Criteria:

  • History of surgery or major trauma to the spine
  • Current use of medication known to impair physical effort and pain perception
  • Lumbar scoliosis of more than 20°
  • Collagenosis, severe osteoporosis
  • Neuromuscular disease
  • Malignant tumor
  • Non-controlled hypertension
  • Infection
  • Radiculopathy
  • Progressive neurologic defect
  • Myelopathy
  • Lumbar disc hernia
  • Pregnancy
  • Active lower body injury and/or severe and disabling pain limiting the capacity to undergo the evaluation.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
