please send infornation about modeling and control of human balancs

Modeling and assessment of human balance control
maintaining an upright stance is a complex process which involves many sensory and motor processes in the background. The different signals of the body has to be interpreted, these signals have to be interpreted in the brain, and appropriate control signal has to be sent to activate the muscles. The three major sources of sensory information involved in the process of control of balance are:
-the vestibular system
-the visual system
-the proprioceptive system
The relative weighting of each of the sensory modality considering the task and the environmental context is also vital to the maintenance of the balance of the body. redundant sensory information is present in the healthy individuals whereas the diseased ones have less control due to impaired quality of sensory information.
The the balance control system of the body is a closed-loop. Many mechanical and sensory disturbances are provided to disturb the balance so that the contribution of the body and central nervous system to the process of body balance can be identified and studied. The frequency domain closed-loop system identification techniques are used to this end.
