There are many writing aids available now for people with limited hand function. Writing aids vary from a simple letter writing guide which helps people with low vision or limited hand movement to write in straight, evenly spaced lines to pens and pencils which have triangular supports or cushions which balance and guide the hand while writing. These are very useful for individuals who have limited strength and control in their hands. Most writing aids can improve shaky handwriting and can be used by right or left handed writers.
