A recipient of the prestigious Medical Design Excellence Award, this is the hand fitness trainer that can slow the progression of osteoarthritis and mitigate the effects of repetitive-motion injuries in the hands. The device slips on like a glove and has latex-free elastic bands that strap to each fingertip, providing resistance as you open your hand. By flexing your hand in the opposite direction of its typical motion, the trainer strengthens the extensor muscles in your hands, wrists, and elbows, helping to reduce the painful symptoms of carpal tunnel syndrome, tennis elbow, tendonitis, and prevent future injuries. Ideal for people whose careers or hobbies require manual dexterity, the device strengthens underused muscles and improves flexibility of overworked muscles in the palm, resulting in improved muscle balance and joint stability. The resistance can be adjusted individually for each finger and the strengthened bands stay in-place dutifully during rigorous hand exercises. A normal exercise routine consists of a few minutes a day, every other day. Made in the U.S. For use with either hand; one size fits most. (5 oz.)
