Computer Simulation Study of Human Locomotion with a Three-Dimensional Entire-Body Neuro-Musculo-Skeletal Model. II. Biomechanical Relationship between Walking Stability and Neuro-Musculo-Skeletal System.

A Robotic Model of the Human Neuro-Musculo-Skeletal System

A pair of muscles powering the human joint in an antagonistic configuration exemplifies the main difference between standard industrial robots and biological motor systems. Since muscles have a natural stiffness that varies with the muscle activation level, the central nervous system can generate stable equilibrium postures, towards which the arm is attracted, by properly regulating the activat...

Hip compression force estimation with a comprehensive musculo- skeletal model

(1) In many models muscle force can instantaneously drop to zero or rise to maximal force (e.g. [2]) However, in reality muscular dynamics will prevent such fast transitions in force. (2) Objective functions based on mechanical measures such as muscle force or stress are frequently used (e.g. [3]). However, the validity of these functions is unknown. A recent study posed an energy-related cost ...

Title : Neuro - Musculo - Skeletal Torque Generation Process Has a Large Destabilizing Effect on the Control Mechanism of Quiet Standing Abbreviated Title : Neuro - Musculo - Skeletal System in Controlling Quiet Standing

The delay of the sensory-motor feedback loop is a destabilizing factor within the neural control mechanism of quiet standing. The purposes of this study were 1) to experimentally identify the neuro-musculo-skeletal torque generation process during standing posture, and 2) to investigate the effect of the delay induced by this system on the control mechanism of balance during quiet standing. Ten...

Musculo-skeletal ultrasound in rheumatology practice.

In rheumatology ultrasound is a relatively new but rapidly developing field, and now forms an important part of curriculum of rheumatology training programs in European countries. Ultrasound is now an accepted procedure to differentiate between arthralgia and arthritis, to look for erosions in early arthritis which is otherwise not visible on plain radiographs, to scan tendons in enthesopathies...
