Lumbopelvic ratio based screening tool for Lumbar health assessment

Low Back Pain (LBP) is a global health issue that affects individuals of all ages and professions. Work-related musculoskeletal disorder (WSMD) is a condition experienced by an average of 60-85% of adults within their lifetime. Although several studies have investigated non-invasive methods to control or reduce the workload, there remains an unmet clinical need. Hence, the main objective of the study was 1. to investigate the lumbar spine dynamic range of motions (flexion, extension, axial rotation, and lateral bending) at various speeds (fast, normal, and slow), and 2. to investigate the relationship between lumbosacral moments and lumbopelvic ratio (also known as hip-spine coordination ratio). The results obtained from this study could help in developing methodologies or as a screening tool to prevent WSMD at the early stages. Utilizing digital technologies such as smartphones or standalone digital mirrors, markerless health assessment can be performed and the health status of the lumbar spine can be visualized instantly.
