The Hand Exercise Board is a great table-top physical therapy tool that helps strengthen and improve the user's wrists, hands, and forearms. It can be used to improve manual dexterity, pronation, supination, and wrist flexion or extension. Included are 7 tools that come in a variety of shapes and sizes. The tools attach to the board through the hook and loop strips to help the user improve pinching and gripping skills. They are designed to increase hand and finger strength, dexterity, and range of motion. The four suction cups found on the bottom of the board keeps it securely in place during use. The larger finger rollers are used to decrease resistance and the small rollers are used to increase resistance. You can increase the handle circumference of the wrist roller to make exercises easier. The board measures 9 inches wide, 13 inches long, and comes with one block and six hook-covered rollers.
