Aims
The importance of Information in action(Evolutionary Effects and Behavioral Acts)
The difference between perceptual system and behavioral system is very important for the sense psychology but it has not been emphasized in biomechanics, and particularly in the experimental literature.
Movement is of two general types, exploratory and performatory, the first serving perception and the second behavior.
James Jerome Gibson (January 27, 1904–December 11, 1979), was an American psychologist
Edward S. Reed (November 20, 1954 - February 14, 1997) was a philosopher of science and an ecological psychologist in the vein of James J. Gibson.

The second aim of our study was to apply the perception-action coupling manifold to contrast how an expert and a novice player move across the information manifold of perception and action to produce a golf swing (Lagarde, Kelso, Peham, & Licka, 2005).

Computational framework to predict the constraint forces was shown with the proposed knee model. Judicious choices of the virtual displacement (i.e. IAK) are crucial because the principle of virtual work for static equilibrium was applied on these special axes among tentative axes.

: A special line complex is the linear line complex defined by a single twist . Every marker point of the segment has its velocity vector tangential to the helix that passes through it. The pattern of this velocity vector is a helicoidal velocity field. Each marker point that does not coincide with the twist axis of is referred to as a pole. Associated with each pole is its corresponding polar plane. Shown are a polar plane and its corresponding pole as defined by the instantaneous screw axis .The ISA used to transform the marker set to must be determined form cylindroids . and are two twists of zero pitch on the cylindroid .

Conclusion
The layout of physical surfaces, according to this theory, is perceived by the way of the disposition of body members when touch and posture are covariant.
The covariance of cutaneous and articular motion is information in its own right.
The units of anatomy are not the units of function. The movement systems are characterized by based primarily on purposes.
Fascia is this layer which is the translator of our touch to the deeper tissues beneath
My ultimate concerns arise from those therapists who think that in order to go deep you have to go in hard. You don’t and you shouldn’t.
