The preset body part programs are available for convenience, but they are not necessarily exclusive, meaning you do not necessarily have to only choose a specific preset program and only use it on that corresponding are of the body. You can certainly experiment and try using the different programs on other areas and compare the difference. For example, you mat notice that one of the hand settings feels good on your elbow, or perhaps one of the foot programs, etc. They are really meant to be used as a guide and recommendation. OR... you can always adjust each parameter manually (pulse width, pulse rate, etc.) by setting "Program U1" on any area of the body, and just skipping the presets, if you wish to do so. Always heed the advice of your medical practitioner for what is optimal and recommended for your particular case, as everybody is different.
