Torque Production and Low Back Forces in Standing and Kneeling Back Exertions.
Paper in XIII Int'l Congress Biomech Book of Abstracts Univ of Western Australia Pp 222-223 :222-223
In certain workplaces, workers are required to perform heavy lifting tasks in a kneeling posture (e.g., underground miners, aircraft baggage handlers). While a great deal of information has been gathered on standing back strength capabilities, little is known about how the kneeling posture affects back strength or the load experienced by the lumbar spine. This U.S. Bureau of Mines study examined peak isokinetic torque production and used an electromyogram-driven low-back model to predict compression and shear forces on the lumbar spine during dynamic maximum voluntary contractions (mvc's) in standing and kneeling postures.
