Dynamic forces induced by humans walking change simultaneously in time and space,
being random in nature and varying considerably not only between different people but also …

The rising importance of movement analysis led to the development of more complex
biomechanical models to describe in detail the human motion patterns. The models scaled …

A new musculoskeletal model for the lumbar spine is described in this paper. This model
features a rigid pelvis and sacrum, the five lumbar vertebrae, and a rigid torso consisting of a …

Body segment inertial parameters (BSIPs) are important data in biomechanics. They are
usually estimated from predictive equations reported in the literature. However, most of the …

We developed and validated a fully articulated model of the thoracolumbar spine in opensim
that includes the individual vertebrae, ribs, and sternum. To ensure trunk muscles in the …

Study Design. Biomechanical analysis of proximal junctional kyphosis (PJK) through
computer simulations and sensitivity analysis. Objective. To gain biomechanical knowledge …

Background and Purpose Patients with increased thoracic curvature often come to physical
therapists for management of spinal pain and disorders. Although treatment approaches are …

Vertebral fractures occur most frequently in the mid‐thoracic and thoracolumbar regions of
the spine, yet the reasons for this site‐specific occurrence are not known. Our working …

BACKGROUND CONTEXT: Sagittal profiles of the spine have been hypothesized to
influence spinal coupling and loads on spinal tissues. PURPOSE: To assess the relationship …

Despite the well-recognized role of lifting in back injuries, the relative biomechanical merits
of squat versus stoop lifting remain controversial. In vivo kinematics measurements and …
