The contribution of load magnitude and number of load cycles to cumulative low-back load estimations: A study based on in-vitro compression data

Background: Cumulative low-back load is suggested to be associated with low back pain, possibly due to (micro-)fractures of spinal segments. Based on available in vitro data it can be assumed that, in order to predict spine segment failure from cumulative compressive loading, load magnitude should be weighted with an exponent higher than one,...
