I have been reading about how to apply splints for contracted tendons. How far up the leg do I need to go? My doeling born last night has them, just her pasterns, not the knees. Should the splint be below the knee? Should it touch the ground? She is really making an effort to get around, but I think a little extra help would be good for her. (Yes, I already did the selenium/Vit E. and will continue) She is a triplet and the smallest. Born last night.
