Yes and no. Each weapon has a set chance to trigger some sort of status effect. I think the effect it triggers is based on a lottery between all the damage types on a given weapon, with a greater chance being given to the dominant damage type. This mod increases Impact damage as opposed to Slash and Puncture, which would slightly raise the odds of getting the Impact status proc, which is a slight knock-back effect accompanied by a pleasant "ding" sound.

If you want full-on knock-down, I'd look into Blast damage (Heat + Cold).
