Shrubs still lay prostrate under wet snow and as long as they are not cracked, just leave them be.
Warm weather will eventually release them and once free, the plants will hopefully return to their previous shape. Hopefully is the key word, but just keep an eye on them. I've got azaleas flattened by the February snowstorm that have recently come back to form. Tougher plants like burning bush and junipers will rebound when given a chance.
If trunks and branches are cracked beyond repair, get a good pruning saw and remove them. A sharp saw specifically meant for pruning will make the job easier and it's better for the plant to have a clean cut. When plants are drooping, make two cuts to avoid damaging the plant. The final cut leaves about a quarter-inch stump; the first cut is made 12 inches out from that. If only one cut was made, you'll risk stripping bark as the limb falls.
Plants are resilient. In a month they'll be back to normal.
