The effects of keyguard use and pelvic positioning on typing speed and accuracy in a boy with cerebral palsy.

The effects of keyguard use and pelvic positioning (neutral versus posterior tilt) on typing proficiency was studied in an 8-year-old boy with athetoid and spastic cerebral palsy. Speed and accuracy were measured with the Mastertype computer software program (Zweig, 1984). The results showed that the use of a keyguard increased the subject's typing accuracy and decreased his speed. Neither neutral nor posterior pelvic positioning appeared to have a significant effect on typing speed or on accuracy.
