The last few days Matthew seems to be hyper extending his knees more often than he has been. We are using his braces when he is active at school and home and keeping them off when he is sitting not walking around much. We are not sure if his braces are a big benefit to him or not. He still finds a way to hyper extend his knees when he is wearing his braces. We have noticed that he doesn't hyper extend his knees as much with the braces on. This picture is from last night. As soon as Matthew stands in one position for more than a few seconds, he usually will look like this. I am going to post this on a parent support group and see if they have any other suggestions .
