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

Completed

• Conditions: Mechanical Low Back Pain; Chronic Low Back Pain

• Registration Number: NCT02226692
• Lead Sponsor: Université du Québec à Trois-Rivières

Brief Summary

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.
