This may be two totally different statistics. There are many musicians who do not disclose their suffering in fear of losing their jobs, especially if they are members of orchestras where each position is sought after by many applicants. Thus the prevalence is extremely high within musicians. It has been suggested that people who are of lesser build and have a smaller body frame are more susceptible to injury due to the forces imposed upon the body by repetitious movements. Symptoms usually result from a sudden increase of practice time, a change of teachers, a change of instruments, and long practice sessions without breaks.
Smokers run a high risk because of nicotine's constrictive affect on the blood vessels.
Pregnant women tend to develop CTS because of fluid retention, but the symptoms usually subside once the pregnancy is over. Previous neck injury from a car accident, from a bad fall, or from any trauma needs to be evaluated. Previous shoulder injuries, such as dislocations are important to note. A history of broken bones in the arm, forearm, wrist, clavicle, shoulder blade can be a predisposing factor. Finally, the particular instrument played by the musician increases susceptibility.
