The Digi-Extend is a unique therapy device that can isolate the extension of all five fingers and each of the individual finger joints. The product strengthens the intrinsic and extrinsic muscle groups to maximize extensor tendon gliding, joint motion. The Digi-Extend is a professional step-up from the simple devices for extensor strengthening and conditioning. Four color-coded band resistance levels allow each muscle or joint to work at a comfortable level and build as increased strength is achieved. Package includes 5 tan (xx-light), 4 yellow (x-light), 3 red (light), and 2 green (medium) latex-free elastic bands and an illustrated pamphlet.
