Musculo-Skeletal System and Human Posture. Human Posture and Its Transition.

Human Arm Posture Control Using the Impedance Controllability of the Musculo-Skeletal System Against the Alteration of the Environments

We show that humans execute the postural control ingeniously by regulating the impedance properties of the musculo skeletal system as the motor command against the alteration of the environment. Adjusting muscle activity can control the impedance properties of the musculo -skeletal system. To quantify the changes in human arm viscoelasticity on the vertical plane during interaction with the env...

A Biologically Inspired Human Posture Recognition System

Effects of gravity and posture on the human cardiovascular system

The aim of the study was to get and analyse data on the changes in ECG, heart rate and blood pressure with the change in gravitational acceleration or g. Previous studies conducted in our laboratory showed that regular practice of Sheersasana (a Yogic posture) could possibly help in tuning the cardiovascular system to adapt easily to the accumulation of blood in the upper part of the body as in...

Posture alters human resting-state.

Neuroimaging is ubiquitous; however, neuroimagers seldom investigate the putative impact of posture on brain activity. Whereas participants in most psychological experiments sit upright, many prominent neuroimaging techniques (e.g., functional magnetic resonance imaging (fMRI)) require participants to lie supine. Such postural discrepancies may hold important implications for brain function in ...

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...
