I got constantly blown all over the room while doing the Gauldur Amulet quests (especially with that guy who summons lots of duplicates), but I did this at a fairly high level (high 40s I think) on Master difficulty. I also had the "meditation" Force Without Effort from Paarthurnax, which is supposed to decrease the effects of that shout on you...
I have that and the heavy armor perk (total 75%) AND still get blown across the room sometimes. I think it doesn't help, either for this instance, or is the effect itself is bugged. One would need 100% resistant to test if it is really working.
The best way to avoid or reduce the chances of it is magic absorption.
