Direct Visual Feedback

Direct Visual Feedback also referred to as DVF, 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 a particular movement, motor function or exercise that is being performed by the trainee.

DVF is similar to the principle of Bio-Feedback, which is described by Wikipedia as the process of becoming aware of various physiological functions using instruments that provide information on the activity of those same systems, with a goal of being able to manipulate them at will.  This process 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 brainwaves, heart rate, breathing, muscle activity, pain perception and skin temperature.

The method of Direct Visual Feedback applies more directly to improving exterior physical health and performance used in both practical and rehabilitative settings. Instead of using technically advanced measuring instruments for feedback like in Bio-Feedback, DVF relies on a more natural function, the human eye.  This method is commonly done by using a laser beam which is placed on the hand or a motion sensor glove and connected 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, aiding in both the bodies strengthening and recovery process.
