AFCN and LFCN localization and measurement method. A vertical line bisecting the anterior thigh along the sagittal plane is drawn from the center of the patella to the top of the femoral head at the iliac crease (a). AFCN and LFCN branches which innervate the superior patella are located using TENS. Black dots on thigh indicate nerve locations (b). For each nerve location, the distance to and along the vertical center line is measured, denoted by the red dotted lines. A line is drawn from the nerve location to the center of the knee, denoted by the blue dotted line, and the angle between this line and the vertical center line is measured (c)
