Knee Complex in Involution and its implication on how to avoid graft

 impingement

BIOMECHANICS AND FUNCTIONAL MORPHOLOGY LABORATORY

Aims

Observations on active touchThe difference between active touch

and passive touch is very important for the individual but it has not been emphasized in sensory psychology, and particularly in the experimental literature.

Movements and postures are controlled and coordinated to realize functionally specific acts based on the perception of affordances (that is, possibilities for action (Gibson 1979)

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.

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.

It is not that sensations from the skin and the joint are blended or fused when they occur together, as most modern practitioners believed.

Leg stiffness is not directly related to hopping mechanics, but, rather, to the hopping environment.
