Popis: | This study examined the use of four different computer pointing devices on surface electromyographic activity of the index finger, forearm and shoulder/neck muscles among CAD operators in the workplace. Subjects were randomly assigned to use their own mouse, a trackball, a joystick mouse or an experimental mouse. Results showed that there was a statistically significant difference in muscle load for the upper trapezius, extensor indicis proprius, and extensor carpi ulnaris across pointing devices for CAD operations. The flexor digitorum superficialis muscle load remained relatively constant when all pointing devices were compared. |
