Once the writer François Mauriac (1885-1970), he said that, "the man who works with his hands is considered a worker, with his hands and mind, a craftsman, with his hands, his mind and his heart, he is an artist". Common element of all three, the use of their hands, the organ that nature adapted evolutionarily, so that we and the other primates can hold, grasp and create. The clinical condition results due to entrapment of the middle nerve of the hand, is referred to as "carpal tunnel syndrome" and it is recognized as a purely professional syndrome, with all that this entails for health and safety policies at work and the corresponding legislation.
