ROM or Range Of Motion is both flexion (bending) AND extension (straightening)
Range of motion or ROM is a medical/anatomical definition not a mathematical one. The range of 180-360 degrees is not factored in, presumably because the lower leg cannot move in an entire circle!
To measure degrees of flexion using the goniometer, the zero is on the ankle and the 180 on the hip. Thus full extension is 0 degrees. As the foot moves towards to hip, so...
