Frequency of Correct Response and Factors Associated in the Medium Term With a Multimodal Rehabilitation Program for Chronic Low Back Pain

Chronic Low-back Pain

Non-specific chronic low back pain is defined as pain that originates in the lumbar spine, is persistent, lasts more than 3 months, and is unrelated to an inflammatory, traumatic, tumour, malformation, or infectious cause. Chronic low back pain is one of the most frequent reasons for consulting a physician, and one of the most common sources of disability, particularly as a result of socio-professional withdrawl. It is a major consumer of health resources (diagnostic investigations, multiple treatments) and involves heavy expenses for the investigator's health insurance system. In view of this major public health issue, in November 2017, the Health Insurance and several specialized health organizations launched a general public campaign to raise awareness of low back pain. This campaign, entitled Back pain? The right treatment is movement was designed to encourage appropriate physical activity in patients with low back pain. Among the available therapies, multimodal programs are recommended as a first line treatment. In order to incorporate physical activity into patients' daily lives, these rehabilitation programs are based on a comprehensive multidisciplinary approach (therapeutic education, muscle strengthening, reconditioning, ergonomics, psychological, social, professional and nutritional management and cardiovascular risk factors). Although such programmes have already shown short term effectiveness, few data are available on their continued effectiveness in the medium term (1 year). This project aims to identify good and bad responders to a multimodal program in the medium term, based on common clinical parameters (Quebec City questionnaire score and spontaneous walking speed), and to identify the mechanisms underlying this response. In addition, in clinical practice, heterogeneity in maintaining the effectiveness of the program is observed but little documented. The limited data available show a heterogeneity of these programs and one of the objectives of this project will be to identify the existing barriers and levers available to improve this situation.
