Low back pain is presently the first cause of disability worldwide. The most recommended interventions by clinical guidelines are exercises and cognitive behavioral therapy although the effect is modest. However, no approach is superior when given to a heterogeneous group of subjects with chronic low back pain (CLBP). This is probably due to the multiple factors associated with CLBP which are biophysical, psychological and social. Thus, each patient presents with a unique profile of factors contributing to their pain and could benefit from an approach tailored to their profile. In other words, it is crucial to identify the right treatment, for the right person, at the right moment. For example, the presence of important psychological factors such as anxiety and depression are risk factors for low back pain to develop and persist over time. The main aim of this project is to determine the feasibility to perform a large clinical trial comparing the efficacy of a two physiotherapy's approaches to treat CLBP (i.e., a psychologically-informed physiotherapy intervention compared to usual physiotherapy) in patients with CLBP presenting a high level of psychological factors.

In other words, it is crucial to identify the right treatment, for the right person, at the right moment. For example, the presence of important psychological factors such as anxiety and depression are risk factors for low back pain to develop and persist over time. Empowerment of physiotherapists and patients on the optimal management of psychosocial factors, in addition of the usual care delivered in physiotherapy, may be a potent strategy to improve the treatment effect especially with patients presenting a complex clinical profile. This empowerment may be done through psychologically-informed physiotherapy, an approach incorporating strategies from cognitive behavioral therapy into the physiotherapy usual practice. However, the feasibility to perform a clinical trial including psychologically-informed physiotherapy in the context of the Quebec's healthcare system remains to be verified.
The main aim of this project is to determine the feasibility to perform a pilot randomised controlled trial testing the efficacy of a psychologically-informed physiotherapy intervention in CLBP patients with a high level of psychosocial factors compared to usual physiotherapy. Specific aims are related to feasibility (1) and sample size estimation (2):
The hypothesis is that this project will be feasible in terms of recruitment for both patients (~30) and PT (6-8), will show good patients and physiotherapists' adherence to intervention and low contamination between treatment sites. An improvement for all pain-related outcomes in both groups, but more in the psychologically-informed physiotherapy group, is also expected.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Usual care in physiotherapy | Active Comparator | The usual care group will receive interventions recommended by clinical guidelines: education on the nature of LBP, advice to stay active and to continue usual activities, specific exercise programs combined with orthopedic manual therapy. |
|
| Psychologically-informed physiotherapy intervention | Experimental | The psychologically-informed physiotherapy group will receive the control intervention enhanced with specific interventions targeting psychosocial factors (e.g., positive reinforcement, mindfulness-based stress reduction, diaphragmatic breathing, graded exposure). Most of these techniques are efficient to mitigate the impact of psychological factors such as anxiety and fear of movement. To standardize the psychologically-informed physiotherapy approach, physiotherapists will receive a two-day training course by a physiotherapist expert with this approach in chronic pain conditions (Alain Gaumond). |

|---|---|---|---|---|
| Physiotherapy | Other | Participants from each group will receive 8 intervention sessions (45 min) over 11 weeks by a physiotherapist. For both groups, each intervention will be tailored to the patient's profile and the choice of interventions and parameters will be at the judgment of the physiotherapist. |
| Measure | Description | Time Frame |
|---|---|---|
| Recruitment rate of participants | The number of participants contacted divided by the number of participants recruited. | Baseline |
| Physiotherapists adherence to intervention | Physiotherapists will complete a list of interventions used after each interventions (8 interventions on period of 6 weeks). | Week 6 |
| Risk of contamination between treatment sites | The list of interventions used by physiotherapists at each site will be compared to evaluate the risk of contamination between treatment sites. | Week 6 |
| Specific challenges | Using semi-structured interview with the physio. | Through data collection completion, an average of 1 year |
| Retention of participants | The number of participants who completed the study divided by the number of participants that were recruited. | Baseline, when a participant drop out |
| Participants adherence to intervention | Participants will measure their adherence to intervention on a Numeric Rating Scale from 0 (not adherent at all) to 10 (completely adherent). | Week 6 |
| Measure | Description | Time Frame |
|---|---|---|
| Physical functioning (ODI) | The Oswestry Disability Index (ODI) is a self-completed questionnaire on estimated disability including 10 questions rated on a 6-item scale, from 0 (no disability) to 5 points (maximal disability). | Baseline, Weeks 6, 12 and 24 |
| Pain intensity (NRS) |

The Numeric Rating Scale (NRS) is an 11-point scale used to score the intensity of pain in the last week ranging from 0 (no pain) to 10 (worst imaginable pain). |
| Baseline, Weeks 6, 12 and 24 |
| Quality of life (SF-12) | The 12-Item Short Form Survey is a self-completed questionnaire counting 12 questions on eight mental and physical health domains. The score is calculated by a specific calculator that compares the score to the general population. | Baseline, Weeks 6, 12 and 24 |
| Fear of movement (TSK-11) | The Tampa Scale of Kinesiophobia is a self-completed questionnaire used to assess fear of movement using 11 questions on a 4-point scale ranging from 1 (strongly disagree, low level of kinesiophobia) to 4 (strongly agree, high level of kinesiophobia). | Baseline, Weeks 6, 12 and 24 |
| Catastrophizing thoughts (PCS) | The Pain Catastrophizing Scale (PCS) is a self-completed questionnaire of 13 questions measuring catastrophizing thoughts contributing to pain on a 5-point scale ranging from 0 (not at all, low level of catastrophizing thoughts) to 5 (all the time, high level of catastrophizing thoughts). | Baseline, Weeks 6, 12 and 24 |
| Self-efficacy (CPSES) | The Chronic Pain Self-Efficacy Scale (CPSES) (short form) is a self-completed questionnaire of 6 questions measuring self-efficacy on a 10-point scale from 0 (not at all confident, low self-efficacy) to 10 (completely confident, high self-efficacy). | Baseline, Weeks 6, 12 and 24 |
| Participant's expectations | Participant's expectations regarding treatment will be measured with a self-completed questionnaire of three 7-level Likert questions on pain, physical functioning and participation ranging from 0 (way better) to 6 (way worst). | Baseline, Weeks 6, 12 and 24 |
| Central Sensitization (CSI) | The Central Sensitization Index (CSI) is a self-completed questionnaire of 9 questions measuring central sensitization on a 5-point scale from 0 (never, low level of central sensitization) to 5 (always, high level of central sensitization). | Baseline, Weeks 6, 12 and 24 |
