Experiences and Perceptions of Older People With Chronic Low Back Pain After 8 Weeks of a Specific Group-Based Exercise: Qualitative Analysis of the ESCAPE Trial

INTRODUCTION: Chronic low back pain (CLBP) is a prevalent musculoskeletal condition worldwide, with physical exercise being the primary management strategy. However, this approach poses a significant challenge among the older population, as older people with CLBP often demonstrate low adherence to exercise-based treatments. Despite this, there is limited research evaluating the perceptions and experiences of older people regarding group exercise protocol (GEP) specifically designed for this population, which could enhance adherence and outcomes. OBJECTIVE: To explore the perceptions and experiences of older people with CLBP regarding a GEP tailored to their needs. METHODS: A qualitative interpretative phenomenological approach was employed to investigate participants' experiences after an 8-week GEP. Data were collected through focus groups guided by a trained researcher. The Bardin's content analysis was conducted. To facilitate the analysis and generate graphical representations, IRAMUTEQ (Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires) software was used. RESULTS: The results suggest that the perceptions of older people with CLBP regarding the GEP can be categorized into three thematic clusters: (a) social interaction, mutual support, and community integration with group exercise; (b) comprehensive benefits of specific group exercise on quality of life, sleep, and autonomy for older people with CLBP; and (c) perceived benefits of group exercise in managing low back pain and improving balance and mobility. CONCLUSION: Older people with CLBP can achieve biopsychosocial improvements through adherence to a tailored GEP. Strategies such as locating sessions in community centers, adapting exercises to individual capabilities, and fostering social bonds effectively promoted high adherence, enhanced social relationships, and improved sleep quality.
