Study Design A combined finite element and optimization approach was developed to
investigate the clinically relevant biomechanical parameters of the muscular lumbar spine …

A combined finite element and optimization approach to study the effects of muscles on the
biomechanics of the lumbar spine was initiated. Briefly, a three-dimensional, nonlinear, finite …

Compression on the lumbar spine is 1000 N for standing and walking and is higher during
lifting. Ex vivo experiments show it buckles under a vertical load of 80–100 N. Conversely …

Muscle forces stabilize the spine and have a great influence on spinal loads. But little is
known about their magnitude. In a former in vitro experiment, a good agreement with …

Study Design. This article describes the development of a musculoskeletal model of the
human lumbar spine with focus on back muscles. It includes data from literature in a …

Study Design Task-specific and subject-specific lumbar trunk muscle function, muscle
geometry, and vertebral density data were collected from 16 men. A biomechanical model …

Using two nonlinear finite element models of the lumbar spine, the concept of optimal
posture is explored by minimizing the segmental sagittal moments required for the …

Irrespective of the lifting technique (squat or stoop), the lumbar spine posture (more kyphotic
versus more lordotic) adopted during lifting activities is an important parameter affecting the …

A combined approach involving optimization and the finite element technique was used to
predict biomechanical parameters in the lumbar spine during static lifting in the sagittal …

Study Design. In vivo measurements and model studies are combined to investigate the role
of lumbar posture in static lifting tasks. Objectives. Identification of the role of changes in the …
