Online Physical Exercise for Chronic Low Back Pain

Technology-based interventions, specifically web-based platforms, have been used during the pandemic and, to a lower extent, prior to it, to maintain and improve physical and mental health while avoiding physical contact and therefore, risk of contagion, but also facilitating access to services such as psychotherapy or rehabilitation. Specifically, remote interventions have shown to be effective in the management of symptoms of people with chronic musculoskeletal pain, including chronic low back pain (CLBP). The objectives are to develop and evaluate the feasibility and effectiveness of these interventions, and to examine factors such as age and gender on implementation and adherence, as well as to validate the effectiveness of the interventions in improving CLBP outcomes and compare the effects of two different modalities of remote intervention (interactive and pre-recorded videos) against a waitlist control group. The study is an interventional proof-of-concept pilot study. Participants will be 45 people with CLBP aged 18 to 80 years who are able to consent, have no contraindication to physical activity, and can communicate, read, and understand French. Participants will be randomly divided into 3 groups: an interactive physical activity group, a video physical activity group, and a control group. Recruitment will be done from participant pools of the Quebec Pain Research Network, the Centre de Recherche de l'Institut Universitaire de Gériatrie de Montréal (CRIUGM), the Association Québécoise de la Douleur Chronique, and former participants of the laboratory's research projects. The intervention will last 12 weeks and consist of 3 physical activity sessions per week for the intervention groups. The interactive group sessions will be live via Zoom and the video sessions will consist of be pre-recorded videos. The control group will be instructed to continue their lifestyle habits throughout the study. Assessments will be conducted at weeks 0 and 12 via videoconference, telephone or lime-survey format to measure physical health, mental health, lifestyle, and quality of life. It will also evaluate the feasibility and adherence of the interactive or video technology. The study will also take into account age, gender and baseline pain intensity as potential confounding factors, by introducing them as covariates. We will use ANOVAs to compare the effects of the intervention on the variables of interest between groups. The primary variable will be pain intensity from the National Institutes of Health minimum dataset for chronic low back pain. Other variables form this dataset will be explored as secondary outcomes, along with variables related to physical performance. The study aims to recruit 60 participants, with a 25% dropout rate, to have a sample size of 45 participants completing the project in order to detect a small effect size.
