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 coordination and muscle function in the hand and forearm. The Digi-Extend focuses on the extensor mechanism of one or all fingers as it targets the area of the hand that needs rehabilitation. Patients can easily change the resistance levels and vary their hand positions for specific exercises to help maximize the exercise goals and prevent injury. The Digi-Extend can also be used for finger adduction abduction blocking and flexion exercises. The Digi-Extend is a professional step-up from the simple devices presently available on the market for extensor strengthening and conditioning. It is compact in design high-tech easy and comfortable to use as well as effective in helping patients reach their therapy goals. Four color-coded band resistance levels allow each muscle or joint to work at a comfortable level and build as increased strength is achieved.
