I've actually found controlled training has helped rehab golfer's elbow.
Slowly going up and down a mini campus board with feet on the floor, only what I can do with no pain. Lock offs aggravate my elbow, so I think it helps to very gradually strengthen that move. I move the feet a little deeper if that it feels easy, or do bigger lock offs, or use smaller holds. I imagine you could do the same thing with a woody.
And then some hangs on the same board, with hands in different positions - some with both hands on the same rung, some with hands on different rungs.
Just 20min of this per night at first. Very gradually progressing to small campus moves on the bigger holds. And always stopping if there is a twinge. I think it's important to not overdo it. Treat it as movement rehab, not a training session, so there isn't a temptation to push on through pain. And then do rehab exercises after.
Last time I had elbow issues, this kept my fingers fairly strong and made the transition back to climbing easier.
