Direct Visual Feedback is a method of training used in both practical and rehabilitative settings where the attention of the trainee is tied to an external visual cue in reference to the particular
movement, motor function or
exercise that is being performed by the trainee.
The principle to
Bio-Feedback is very similar to DVF. Bio-Feedback, which is a process that enables an individual to learn how to change physiological activity for the purposes of improving health and performance by receiving rapid feedback from precise instruments which are measuring physiological activity such as

Neural oscillations, or brainwaves, are rhythmic or repetitive patterns of neural activity in the central nervous system. Neural tissue can generate oscillatory activity in many ways, driven either by mechanisms within individual neurons or by ...

on the hand and connecting it to a monitor, when the trainee raises his arm from waist height to shoulder height he is focused on the external reference showing exactly what path the arm took from point A(waist height) to point B(shoulder height). Studies have shown that not only is a higher level of performance often achieved faster with an external rather than an internal attention focus, but the skill is retained better.
