My sister has scoliosis. As a child my parents took her to see a doctor and my mom told us kids that there was nothing they could do. My parents didn't have a lot of money so if the doctor did suggest surgery they would not have done it. I believe they thought it wouldn't get worse. Well, it did. It progressively got worse even as an adult. I forget what degree her curve is. It's drastic. She does not have PD but has other health problems. She is 71. I know her lung problem is connected to the scoliosis but don't think the other problems are related.

I wasn't sure if you wanted all cases of scoliosis or just if they also had PD.
