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

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.
