Nah, just the arm. It has more RP effect than battle effect, depending upon the situation. For example, "Bruised" has to clarify a specific area, so if they for whatever reason said, "Imma punch yall in the arm!" then they'd be unfortunate. If an Ice technique were to try to freeze the arms together, then the inflicted arm could not be "Frozen." So in truth, it's not the whole body, but if they are in any way targeting this specific arm, then those status effects are null. At least, that was my thought.
