Spine loading during asymmetric lifting using one versus two hands
Article Abstract:
Three-dimensional spinal loading associated with asymmetric lifting was investigated while using either one or two hands to perform the task. Results indicated that spine compression and lateral shear forces increased as the lift origin became more asymmetric. An inverse relationship was found between anterior-posterior spinal shear and asymmetry. One-hand lifting significantly changed the compression and shear profiles. These reflect the trade-offs that must be considered among spinal forces during asymmetric lifting while using one or two hands.

Injury-induced kinematic compensations within the lower back: Impact of non-lower back injuries
Article Abstract:
A study was conducted to quantify the impact of non-lower back injuries on the trunk motions adopted by the individual during typical lifting tasks. Result states that injuries to the upper and lower extremities could predispose a worker to increased lower back disorder (LBD) risk through altered spinal kinematics that result from compensatory responses.

Free shoulder space requirements in the design of high backrests
Article Abstract:
A study conducted to determine the influence of scafular support on the effects of lumbar support and to prove that a high and straight backrest is inappropriate is presented. According to the study, high and straight backrest overrules lumbar support.
