Unobtrusive Wearable System for Load Vertical Location Estimation.

Low back pain (LBP) is a leading musculoskeletal disorder, and manual material lifting is proven to be a major cause of LBP. However, current solutions for monitoring a major LBP risk factor - load vertical location (LVL), are not user-friendly or accurate, which makes them impractical for real-world applications. To address these problems, a user-friendly wearable system was proposed in this study to realize an accurate measurement of LVL over time.
