Figure 2. Two-dimensional maps.

Figure 2

The color code of each map of FCR (A) and ECR (B) muscles ranges from gray (0 mV) to white (0.5 mV or over). The map areas of the FCR and ECR muscles clearly overlapped, although they were spread differently. The center of gravity (black circle) of the FCR muscle was located at x (anteroposterior)  = 6.5±2.6 mm and y (mediolateral)  = 56.5±2.3 mm and that of the ECR muscle was located at x = 4.5±3.6 mm and y = 56.4±2.7 mm. FCR: flexor carpi radialis; ECR: extensor carpi radialis.
