Could the spastic or athetoid movements bring on preterm labor?
From my two experiences with pregnancy, my spastic and athetoid movements never became an issue. I was induced at 39 weeks with my first child and with my second I went into labor on my own at 37 weeks (40 weeks is considered a full-term pregnancy). I had Braxton Hicks contractions with my pregnancies, as most everyone does near the end of their pregnancies. Both times, the nurses said that I had an irritated uterus, which could be caused by a tilted uterus, but was not related to having CP.
