Computer Professionals and Carpal Tunnel Syndrome (CTS)
Carpal Tunnel Syndrome ( CTS ) is an important problem among computer professionals . Hence the prevalence of CTS among computer professionals and risk factors were studied . 648 subjects were selected from 4,276 computer professionals from 21 companies with a simple r and om sampling method . CTS was diagnosed based on clinical features . The prevalence of CTS was found to be 13.1 % ( 95 % CI 10.5–15.7 % ) . Subjects with over 8 years of computer work , over 12 hrs of work per day and system administrators were at a higher risk for CTS ( OR 3.3 , 4.9 and 2.5 respectively ) . Flexed or extended h and position had higher risk for CTS . Higher risk for CTS was found with higher exposure to computer work . Ergonomic considerations are important in facilitating proper positioning of h and while working with a computer . Further studies on CTS risk factors among computer professionals are essential for planning prevention
