Helo,
It is good and profesional to concider the ICF when making a treatment plan. To involve a treatment on the levels for Structure, Function, Activity and Participating.
And anwser for every level the question What, How, any Why are you treating?
Example: LEVEL STRUCTURE: What? Gluteus Maximus, How? Bridging, Why? for easier sit to stand transfer.
And then also for other levels.
