Physical exercise has a fundamental position in the chronic low back pain treatment. However, the physical activity level is often low in these patients and the adherence to the care program is not enough in the long term. The French Evaluation of the Perception of Physical Activity (EPPA) is a valid and reliable questionnaire, developed by N. Coste et al in 2020, that assesses the perceived barriers to and facilitators of physical activity in patients with knee osteoarthritis. To our knowledge, there is no valid and reliable instrument allowing such an assessment in chronic low back pain.
The main objective of this study is to adapt the EPPA to chronic low back pain and to evaluate its psychometric properties.
This validation would allow its use in current practice to adapt the care strategy, to personalize rehabilitation of each patient with chronic low back pain in order to have a better adherence to rehabilitation programs.
The EPPA was adapted to chronic low back pain and named EPPA-LOMB. It comprises 26 items.
Patients with chronic low back pain will be recruited during a medical consultation in the Physical Medicine and Rehabilitation Department of the University Hospital of Clermont-Ferrand and the Notre-Dame Functional Rehabilitation Center of Chamalières (France); or the first day of a functional spine rehabilitation program (3-week program in a day hospital) in the Physical Medicine and Rehabilitation Department of the University Hospital of Clermont-Ferrand.
Patients will be asked to complete a series of questionnaires after completing the non-opposition form. The management of non-specific chronic low back pain also requires evaluation through questionnaires, in accordance with the usual practices of the services participating in the study. No intervention will be taken.
All patients will complete questionnaires at inclusion.
Patients included during a medical consultation will receive an e-mail to complete online the EPPA-LOMB and visual analogic scales on pain and level of physical activity, 7 days after inclusion.
Patients included the first day of a functional spine rehabilitation program will complete questionnaires at the end of the program, 21 days after inclusion. They will be seen 3 months after their discharge during a follow-up medical consultation and will complete another time the questionnaires. Only patients not included in the study E-lombactifs (NCT04264949) will complete the questionnaire at 3 months.

Visual analogic scale for physical activity
Visual analogic scale for physical activity (VAS physical activity) from 0- no physical activity to 10-very intense physical activity
Time frame: 0 day, 7 days, 21 days, 3 months
Visual analogic scale for pain
Visual analogic scale for pain (VAS pain) from 0-no pain to 10-the worst pain
Time frame: 0 day, 7 days, 21 days, 3 months
OSWESTRY Disability Index (ODI)
The functional disability is measured by the OSWESTRY Disability Index (ODI). Ten items rated from 0 to 5 compose a valid and reliable scale with a total score ranging between 0 and 50.
Time frame: 0 day, 21 days, 3 months
Fear Avoidance Belief Questionnaire (FABQ)
The fears and the faiths are measured by the Fear Avoidance Belief Questionnaire (FABQ). The FABQ can help predict those that have a high pain avoidance behavior. Clinically, these people may need to be supervised more than those that confront their pain. The FABQ contains 2 scales: a work scale (FABQ-W) composed of 7 items and a physical activity scale (FABQ-PA) composed of 4 items. The two scales are scored separately. Higher FABQ scores indicate elevated fear-avoidance beliefs. "FABQ-W" has a point score that ranges from 0-42 points and "FABQ-PA" can range from 0-24 points.
Time frame: 0 day, 21 days, 3 months
Exercise Adherence Rating Scale (EARS)
The Exercise Adherence Rating Scale (EARS) is a reliable and validated psychometric assessment questionnaire that assesses adherence to prescribed physical exercise in chronic low back pain.A 6-item adherence scale assess adherence to prescribed home exercise. These six items are scored on a 5-point Likert scale (0 = completely agree, 4 = completely disagree). Items 2, 3 and 5 are negatively worded questions. Therefore, higher sum scores (0-24) indicate greater exercise adherence by reversing scores of Items 1, 4, and 6. Ten supplementary items assess reasons for adherence and non-adherence.
Time frame: 0 day, 21 days, 3 months
the Hospital Anxiety and Depression Scale (HADS)
The knowledge of emotional state is measured by the Hospital Anxiety and Depression Scale (HADS). The HADS is a valid and reliable self-rating scale that measures anxiety and depression in both hospital and community settings. HADS gives clinically meaningful results as a psychological screening tool and can assess the symptom severity and caseness of anxiety disorders and depression in patients with illness and the general population. The questionnaire, comprising fourteen items. Each item is scored from 0-3 and this means that a person can score between 0 and 21 for either anxiety or depression.
Time frame: 0 day, 21 days, 3 months
