I too fixed my stuck fermentation issue with moving to a pure o2 aeration system. Shaking the hell out of it just didn't cut it.
Also just a PSA... Shaking, dumping, obsessively mixing, whipping, playing the beegees and dancing the hell out of your wort... all can only result in a maximum dissolved oxygen content of 8ppm, since that is the atmospheric concentration. Ideal levels for fermentation are between 12-15ppm of dissolved oxygen. The only way to hit these levels is with a pure o2 system.
That being said everyone has their own method. Do what works for you. If you shake your wort lovingly to get that o2 in there and it works for you, shake your wort. I was seeing stuck fermentations hanging around 1.020 so i got a William's o2 kit and have never had that problem again.
