4. Marsden ball
Activities that are performed with the Marsden ball are fun and perhaps the most desired in the therapy room. We have become experts at making our own balls using a Pinky ball and a baseball glove repair kit. Writing letters on the ball with a Sharpie allows for the activities to focus on visual attention. The ball is hung from the ceiling and can be bunted with a dowel, and hit/caught with the thumbs, palms, and fists (Figure 4).
