Tailwind is an exercise device for people who want to improve their arm function and range of motion. In published clinical studies, stroke survivors with moderate paralysis improved their arm movement with Tailwind, even many years after their stroke. The Tailwind is the Bilateral Arm Trainer with Rhythmic Auditory Cueing (BATRAC) device you've been waiting for. Stroke survivors can recover the life they thought was lost forever with Tailwind.
