The CanDo® Digi-Extend n' Squeeze Hand Exerciser is made of foam, and features a rubber band that goes across the exercise ball for hand extension exercises. Squeezing this hand exercise ball helps develop isolated finger strength, flexibility, and coordination for rehabbing of carpal tunnel, arthritis, stroke, fractures, tendon injury, nerve lacerations, tennis elbow, and many more. Each Digi-Extend has finger and thumb positioning indents and marking for both left and right handed use. There are 3 different sizes of foam hand exercise balls to choose from: small, medium, and large. Included with each ball is an exercise pamphlet to help get you started on which exercises to use. Included with each exerciser are 4 tensions of latex-free resistance bands meant to work on hand extension: tan (x-light), red (light), green (medium), and blue (heavy). See chart below for color to resistance information.
The CanDo® Digi-Extend is also available without the rubber band meant to work on hand extension exercises: the Digi-Squeeze®
