The Xtensor® helps restore hand, wrist and finger function by targeting the muscles and tendons that open the hand. Unique design specifically exercises finger extensor muscles and tendons with pinpoint precision. Each finger band generates resistance through full extensor range of motion all the way to the lateral and medial epicondyles, maximizing synovial fluid production. Resistance can be adjusted for individual digits, and one or all five digits can be exercised at a time. Use for rehabilitation from overuse injuries, trauma or surgery, to relieve pain, or to improve hand strength and dexterity. Provides relief from flexor tendinitis, osteoarthritis, joint stiffness, carpal tunnel syndrome, PDA thumb, Dupuytren's and tennis elbow. Ideal for treating conditions where the flexor muscles are overpowering the extensor muscles, causing unbalanced tension in the wrist and hand. The easy-to-use Xtensor® slips over the hand and effectively exercises the extensor muscles within just a few minutes.
