I am a physician with a strong scientific background in research and it makes perfect sense to me that any repetitive and demanding motions which can be effected with putting the least if any stress into those motions and still get the job done with even greater efficiency, is something of great value and importance. My wife Paula, a classically trained pianist, had received cortisone shots about three years ago and eventually surgery on both hands for three fingers from very painful and incapacitating injuries (trigger fingers) which apparently resulted from her playing. After the surgery, yet another finger was threatening. At that time she met a teacher who suggested she be evaluated by Edna Golandsky [Healthy Typing Inc. Founder] herself. Luckily, Paula chose to give Edna Golandsky a try. During this time, that finger that had been threatening has long since been silent and she even tells me excitedly that she can master, even more quickly, very difficult piano passages. There is no longer any discomfort in either hand or fingers.
