Abstract

The focus of this contribution is to evaluate numerical integration methods with regard to their comparability for estimating cumulative loading based on discrete spinal loads. In this context, the influence of both weighting factors and sampling rate are investigated using a time-varying loading profile recorded in a laboratory study with 12 subjects. A biomechanical model was used to calculate the compression force at L5/S1. Three numerical integration methods were compared. Results clearly confirm the need to establish a standardized assessment procedure for cumulative loading to ensure the comparability of assessment results and promote scientific progress in the field of physical stress assessment.
