A hand therapy kit includes a housing having a lid that is expandable from a folded position to an unfolded position to expose a working surface on an inside of the lid. An elastic cord is attached at two or more anchor points on the working surface to define at least one gap for receiving a finger. The finger can be therapeutically exercised by moving from a first position proximal to the working surface to a second position distal to the working surface. The hand therapy kit can also include removable hand therapy modules, including a therapeutic tracking glove and/or a pressure sensor ball.
