Validation of the French Version of the Fremantle Back Awareness Questionnaire (FreBAQ) in Patients With Chronic Low Back Pain

In patients with chronic low back pain, the Fremantle Back Awareness Questionnaire (FreBAQ) measures the duration and intensity of pain and functional limitations. The FreBAQ is a simple tool created to assess disturbances in the body representation of the back, and the only one existing in chronic low back pain. It is a 9-item self-questionnaire in which each item is measured on a 5-point Likert scale ranging from "Never (score of 0)" to "Always (score of 4)". It assesses neglect, perceived body image of the back, accuracy in proprioceptive perception of back movements.

The psychometric properties of the FreBAQ in English, Japanese, Dutch, Turkish and German are validated and acceptable; however, they have never been studied in French and no validated version of this questionnaire in French exists.

The study investigators hypothesize that the French version of the FreBAQ has good psychometric qualities, allowing it to be used in the French chronic low back pain population.
