Motivational Support Program in Chronic Low Back Pain After Multidisciplinary Functional Rehabilitation (EMOTIV)

Motivational Support Program in Chronic Low Back Pain After Multidisciplinary Functional Rehabilitation

Evaluation of the Effectiveness of a MOTIVational Support Program After Multidisciplinary Functional Rehabilitation in Chronic Low Back Pain

Chronic low back pain (CLBP) is a major public health problem. Multidisciplinary functional rehabilitation program (FRP), which give patients the skills to better manage pain and return to physical activity, are effective in the short term. In the medium and long term, due to lack of motivation, two thirds of patients stop their physical activity again, causing them to fall back into the vicious circle of pain. Investigators hypothesise that a remote assessment and motivational support program (MSP) based on an application, piloted by a care coordinator, could allow the continued improvement of symptoms and activities observed after the FRP programs, and thus limit the consequences of CLBP for the patient and society. The main objective of this study is to evaluate the effect of the motivational support program EMOTIV, on disability and pain at one year, in chronic low back pain patients who have benefited from a FRP program.

Multidisciplinary functional rehabilitation program (FRP) have shown their efficacy in disabilitie patient suffering from Chronic low back pain (CLBP). Unfortunately, at medium and long term two thirds of patients stop their physical activity due to lack of motivation. These patients then fall back into their painful vicious circle. Investigators hypothesis that motivational support program (MSP) based on an application, piloted by a care coordinator could increase the motivation to continue physical activity and thus limit the consequences of CLBP for the patient and society. The main objective is to evaluate the impact of a MSP (EMOTIV) on pain and functional abilities assessed according to the COMI scale (Core Outcome Measure Index), 12 months after a FRP in patients with LPBC. This program is compared to usual care as currently done. The secondary criteria concern: physical, neuropsychological and medico-economical criteria. This is a multicentre, cluster randomized trial. All adult patient suffering from low back pain, having finished a FRP and possessing a smartphone, will be included. Investigators plan to include 150 patients in 6 centres. The duration of the inclusion period is 12 months; The duration of participation of each subject is 24 months. Inclusion will be on the last day of the FRP program. The Follow-up in consultation is scheduled at 3, 12 and 24 months with evaluation of usual criteria (physical, self-questionnaires, and advice on the practice of physical activities depending on what is achieved). In Pitie salpetriere center only, patients will have in addition: lumbar MRI at 3 and 12 months; central pain awareness assessment. The activity of patients in the MSP group will be recorded continuously par EMOTIV App; pain, mental health and days off every week and self-questionnaires at 1, 2 and 6 months. The primary analysis of all endpoints will be performed in the intent-to-treat population, i.e. all patients randomized to the study. The COMI score will be compared between the 2 randomized groups by a linear mixed model.

Chronic Low-back Pain, Multidisciplinary function rehabilitation, Motivational Support Program Emotiv

A motivational support program including a motivational and self-assessment remote application in the form of a Smartphone application for chronic low back pain patients after multidisciplinary functional rehabilitation.

Difference in disability and pain between the experimental (SHP) and control (usual care) groups, measured with the Core Outcome Measure Index (COMI) scale at 12 months.

The Core Outcome Measure Index (COMI) was developed from requirements of international back pain experts. According to European experts, the COMI should currently be recommended in assessment of chronic low back pain. This questionnaire assesses pain and disability in low back pain. It includes 9 items and its score is between 0 and 10. Higher scores is the worse outcome.

Pain will be measured by a Visual Analogic Scale (VAS) with a question about lumbar pain over the last 7 days. Minimum and maximum values are 0 and 100.

Muscular endurance will be assessed by measuring Shirado (abdominal endurance). Its score is between 0 and no limit. 0 is the worse outcome.

Muscular endurance will be assessed by measuring Sorensen (spinal extensor endurance). Its score is between 0 and no limit. 0 is the worse outcome.

Disability and pain will be assessed by the Core Outcome Measure Index (COMI) questionnaire. Its score is between 0 and 10. Higher scores is the worse outcome.

Intensity of physical activity will be assessed by the IPAQ (International Physical Activity Questionnaire). Scoring a high level of physical activity on the IPAQ means the physical activity levels equate to approximately one hour of activity per day or more at least a moderate intensity activity level.

Muscular trophicity will be done by the measurement of the cross-sectional area (CSA) of the extensor muscles at the level of the upper and lower plateaus of L4 at the lumbar spine

Level of anxiety and depression will be assessed by the HAD (Hospital Anxiety and Depression) scale. 14 items rated from 0 to 3. Seven questions relate to anxiety (total A) and seven others to the depressive dimension (total D), thus allowing two scores (maximum and worse of each score equal 21)

Two parameters will be used, in accordance with international recommendations on Quantitative Sensory Testings : the pain pressure threshold using an algometer, at a distance from the painful area (forearm), and the temporal summation by repeating a painful stimulus with a calibrated needle (PinPrick)

The elements for the medico-economic analysis will be collected on the basis of a questionnaire validated in French. The data collected are : - consultations in general medicine and rheumatology as part of the usual follow-up of patients, - biological or imaging examinations carried out for the spinal problem, - medicinal treatments (drugs, infiltrative procedures) and non-medicinal treatments (physiotherapy, others) carried out for the spinal problem, - any hospitalizations related to the spinal problem

Health resource use will be quantified by the number of consultations, biologic and imaging workups, hospitalisations with their motives, and the list of treatments taken by the patients. It will be valued on the basis of the tariffs of the National Health Insurance Fund (CNAM). Health resource use related costs will be expressed in Euros

Health resource use will be quantified by the number of consultations, biologic and imaging workups, hospitalisations with their motives, and the list of treatments taken by the patients. It will be valued using data from the Common Classification of Medical Acts (CCAM). Health resource use related costs will be expressed in Euros

Health resource use will be quantified by the number of consultations, biologic and imaging workups, hospitalisations with their motives, and the list of treatments taken by the patients. It will be valued using data from the Nomenclature of Medical Biology Acts (NABM). Health resource use related costs will be expressed in Euros

Health resource use will be quantified by the number of consultations, biologic and imaging workups, hospitalisations with their motives, and the list of treatments taken by the patients. It will be valued using data from the national scale of costs (ENC) for hospitalisations. Health resource use related costs will be expressed in Euros

Sick leave days will be valued on the basis of the average daily salaries published each year by the French National Institute of Statistics (INSEE, www.insee.fr). It will be expressed in Euros.

Satisfaction with the program will be measured by a Visual Analogic Scale (VAS). Minimum and maximum values are 0 and 100. The better score is 100.

Adherence to the program will be evaluated on the number of connection (minimum value 0 and no maximum)

Adherence to the program will be evaluated on the time of connection (minimum value 0 and no maximum)

Adherence to the program will be evaluated on number of reminders necessary by the coordinator in case of non connection and/or non attendance at the follow-up (minimum value 0 and non maximum)
