Non-Invasive Assessment of Lumbar Spine Tissue Quality: A Framework for Future Translation and Intervention

a representative picture of how therapies can help with back pain

 

Lumbar Spine Tissue

Project Summary

Low back disorders (LBDs) are a considerable problem worldwide, with a lifetime prevalence of 80% among the global population. Additionally, LBD claims are the most common of any body region, rank highest in years lived with disability, and account for over $100 billion annually in medical compensation costs. While LBDs are complex and multifaceted, a mechanical origin is a leading hypothesis. A growing body of evidence shows that the muscles and soft tissues supporting the spine play a critical role in LBD development, and these tissues can deteriorate in ways that diminish the likelihood of recovery and increase the risk for reinjury. Unfortunately, changes to these soft tissues can only be detected by biopsies taken during surgery, meaning opportunities for earlier intervention were missed. Therefore, this project will develop the first non-invasive framework to assess the quality of spinal tissues, combining mechanical testing,  

advanced muscle recordings, and clinical measures. We will apply this framework in sedentary older adults, with or at elevated risk for LBDs. In partnership with the Canadian Centre for Activity and Aging (CCAA), participants will also take part in activity programs to test whether movement can improve spinal tissue health. The results have the possibility to transform early detection and treatment of back problems, reduce failed spine surgeries, and provide scalable, community-based strategies to improve spine health.
