Is someone who is wheelchair-bound obligated to say matir asurim or zokef kefufim if they cannot get up?
There is an argument between the Rambam and the Kolbo (who quotes the Gaonim).
According to the Rambam, one only blesses Hashem for the benefits that he receives in the order in which he receives it.
According to the Kolbo, the blessings are not for his personal benefit, but for the benefit derived by the world. Therefore, one must say all the blessings even if he was awake the whole night.
Moreover, he says that even if one does not receive direct benefit in what the blessing refer, he still receives indirect benefit. For example, a blind person receives benefit from the power of sight in that people could help him.
The Shulchan Aruch (OC 46:8) worries for the position of the Rambam thereby ruling to say the blessing without Hashem's name, but the Rama and the Arizal rule like the Kolbo.
