Spinal Forces During Asymmetric Lifting in Four Postures.
Paper in XIII Int'l Congress Biomech Book of Abstracts Univ of Western Australia Pp 226-228 :226-228
The height of an underground coal mine is generally determined by the thickness of the mineral seam. Since workers must often perform heavy lifts in restricted postures, traditional recommendations for lifting in unrestricted postures may not be applicable to the underground mining environment. For example, the NIOSH lifting guidelines do not encompass restricted postures or asymmetric lifts. Previous U.S. Bureau of Mines studies have used an electromyogram- driven model to examine spinal forces in kneeling postures and stooping postures under a 1/2-m-high ceiling. The purpose of this work is to examine the biomechanical effects of additional postures, restricted and unrestricted, during asymmetric lifting. See also op 8-92.
