Stretching is a great activity for anyone who sits at a desk.  It is especially important for children with Cerebral Palsy or other neurological conditions that cause stiffness of the joints and muscles.  These exercises can be done at least daily and about 10 repetitions per exercise.  Remember to only stretch to point of mild discomfort, and hold the position for a count of five.  Stretching should be gradual and not painful!!
