Abstract
A therapeutic hand exerciser includes a resilient core and a fabric exterior lining. The core is soft, pliable and smooth when squeezed. The soft smooth feel of a segmented polyurethane fabric, such as LYCRA®, also provides a more pleasurable feel than a rubber cover. The addition of the thermo plastic urethane (TPU) lining prevents the core material from passing through the fabric cover.
