ABSTRACT Conventional unpowered lower limb exoskeleton paid little attention to the metabolic cost of body during sit down (SD)/stand up (SU). The SD motion model and characteristics extremity are analyzed; then, a novel is proposed, contribution degree muscles stiffness joints used for determining location energy storage element. relevant in left leg obtained based on Opensim software. results...

A software system, called RTSIMU, was developed for analyzing worker movements in the textile industry using Inertial Measurement Units (IMUs). RTSIMU converts raw positioning data from IMUs into quaternions, which represent orientation relative to Earth, and further translates them angular values of movement. To assess relevant simulate various working (such as abduction, flexion, rotation, el...

A classifier is commonly generated for multifunctional prostheses control or also as input devices in human–computer interfaces. The complementary use of the open-access biomechanical simulation software, OpenSim, demonstrated hand-movement classification performance visualization. was created from a previously captured database, which has 15 finger movements that were acquired during synchroni...

Common practice in musculoskeletal modelling is to use scaled models based on a healthy adult, but this does not consider subject-specific geometry, such as tibial torsion and femoral neck-shaft anteversion angles (NSA AVA). The aims of study were (1) develop an automated tool for creating OpenSim with NSA AVA, (2) evaluate the component, (3) release open-source. Torsion Tool (https://simtk.org...

Running is associated with a high incidence of injuries. Neuromuscular fatigue considered risk factor, suggesting that the body in fatigued state less able to attenuate impact forces sufficiently, which leads overloading and PURPOSE: To model total knee force, consisting reaction muscle forces, using an OpenSim free diagram before after fatiguing run get insight into potential during running. M...
