Well I guess that would depend on what kind of plant. If your talking about a stem plant (ie: rotala, ludwigias, etc), then IME I have not had a stem with no leaves come back. Plants with rizomes, bulbs, or large root systems will, generally speaking, grow new leaves as long as the root, rhizome, etc was still ok.
I have seen plants that most would have thrown out, come back and flourish. The stargrass I currently have for instance was in a plant tank at a LFS
and had only a few leaves per stem, and those were half decayed, because they were not getting enough light. I took them home and planted them and in no time I was overrun with it. Not because I have a green thumb or anything (cause I don't) but because most plants are pretty tough.
