Before our blades even meet, I bring mine up horizontally to stop your blow and thrust my left arm forwards, just below your collar, setting you off balance, and putting your momentum backwards.
Taijutsu integration is to make your attacks more dangerous, but not always to do more damage. As you saw here, my goal wasn't to attack you, but to wind you, and break your balance. This makes it harder for the opponent to react to a follow up attack.
People who use a single sword do a lot of grappling (grabs, pushes, and throws), as well as step-thrusts, like palm strikes. But if they fight with a shield their grappling is basically slimmed down to just how hard they can push the opponent back - throws are much harder to preform, and grabbing becomes indescribably difficult, unless you're actually grappling on the ground; something like Jujitsu.
It all goes back to your fighting style to what kind of physical attacks you use: I like my dual swords, so I do a lot of punches and pommel strikes, as well as step-thrusts and kicks. The only problem with dual weilding is that you don't have a free arm - and that lessens your options for physical attacks.
Like I said, though, taijutsu integration really can't be taught - it comes through experimenting and finding what works for you. Though, this does do well into bringing us into advanced chaining, something as a single weilder, you'll need to know how to block. Ready?
