The current paper aims at assessing the sensitivity of muscle and intervertebral disc force
computations against potential errors in modeling muscle attachment sites. We perturbed …

Background and objective The objective of this study was to investigate the effect of
incorporating various passive elements, which could represent combined or individual …

OpenSim offers a valuable approach to investigating otherwise difficult to assess yet
important biomechanical parameters such as joint reaction forces. Although the range of …

A direct measurement of the complete loads in the spine continues to remain elusive.
Analytical musculoskeletal models to predict the internal loading conditions generally …

Modelling the mechanical effect of muscles is important in several research and clinical
contexts. However, few studies have investigated the effect of different muscle …

Musculo-skeletal modeling can greatly help in understanding normal and pathological
functioning of the spine. For such models to produce reliable muscle and joint force …

During daily activities, complex biomechanical interactions influence the biophysical
regulation of intervertebral disks (IVDs), and transfers of mechanical loads are largely …

Classical rigid musculoskeletal lumbar spine models cannot provide spinal load within
intervertebral discs (IVDs) due to modeling assumptions. The present study develops an …

Finite element (FE) models of the spine have been used to assess natural and pathological
spine mechanics and evaluate performance of various fusion and posterior stabilization …

This research proposes a novel method that evaluates joint reaction forces by motion
analysis using a musculoskeletal model. While general muscle tension estimations minimize …
