I'd try any and all the exercises to strengthen you lower back. Not sure a dead lift hits all the muscle groups you need, nor am I inclined to do dead lifts myself. If you've done them often previously in your life then go for it.

Some physical therapy places are willing to help you figure out what you need. As will a gym if it has persons on staff that actually have some training. Doesn't cost much with either of them to at least get you started on something that you can then do yourself if you don't need their motivation to keep you doing it.
