Because stronger fingers are not able to compensate for weaker ones, an effective exercise and rehabilitation tool is one that allows each finger to work independently. The CanDo® Digi-Flex Hand Exerciser with Spring-Loaded Buttons does just that. Ergonomically engineered to fit comfortably in the palm of the hand, it isolates and develops finger strength, coordination and flexibility using 8 progressive color-coded resistance levels. This versatile hand exerciser can work individual fingers or be compressed as 1 unit to improve hand, wrist and forearm strength as it identifies, tracks and gives immediate positive feedback on the user’s progress. The Digi-Flex grip is made with a pliable Santoprene material that easily snaps onto the handle and comes with a fully illustrated manual.
