From: Myoelectric interface training enables targeted reduction in abnormal muscle co-activation
The two-dimensional mapping of activation weights of the trained muscle pairs whose initial co-activation level exceeded ThCoA (dashed lines). m1 and m2 indicate the activation weights of a pair of trained muscles, muscles 1 and 2. Red, green, and blue indicate the muscle pairs trained for the first, second, and third two weeks in the MyoCI training, respectively. The disparity index (DI) measured the average of the distance between each dot and the solid diagonal line (representing co-activation since the weights were equal) for responders (A) and non-responders (B). The increase in DI indicated a decrease in co-activation
