From: Cortical reorganization to improve dynamic balance control with error amplification feedback
System setup and error augmentation feedback. With mathematical transformation, the visualized postural sway in the error amplification (EA) condition virtually doubled the size of the real execution error displayed in the real error (RE) conditions. The mathematical transformation is displayed in the formula boxes. In contrast, the subjects in the RE condition received on-line error feedback without any manipulation. The subjects could either see real feedback or error amplification feedback, depending on their grouping. (VP: visualized postural sway; RP: real postural sway; VE: visualized error; RE: real error; T: target signal)
