that those with RSI engage in specific strengthening exercises, for example to improve sitting posture, reduce excessive kyphosis, and potentially thoracic outlet syndrome. Modifications of posture and arm use are often recommended. History Although seemingly a modern phenomenon, RSIs have long been documented in the medical literature. In 1700, the Italian physician Bernardino Ramazzini first described RSI in more than 20 categories of industrial workers in Italy, including musicians and clerks. Carpal tunnel syndrome was first identified by the British surgeon James Paget in 1854. The April 1875 issue of The Graphic describes "telegraphic paralysis." The Swiss surgeon Fritz de Quervain first identified De Quervain's tendinitis in Swiss factory workers in 1895. The French neurologist Jules Tinel (1879–1952) developed his percussion test for compression of the median nerve in 1900. The American surgeon George Phalen improved the understanding of the aetiology of carpal tunnel syndrome with his clinical experience of several hundred patients during the 1950s and 1960s. Society Specific sources of discomfort have been popularly referred to by terms such as Blackberry thumb, PlayStation thumb, Rubik's wrist or "cuber's thumb", stylus finger, and raver's wrist, and Emacs pinky.
