The purpose of this study was to systematically review published evidence on
the development, use, and effectiveness of devices and technologies that enable
or enhance self-directed computer access by individuals with cerebral palsy (CP).
METHODS: Nine electronic databases were searched using keywords 'computer',
'software', 'spastic', 'athetoid', and 'cerebral palsy';
the reference lists of
articles thus identified were also searched. Thirty articles were selected for
review, with 23 reports of development and usability testing of devices and seven
evaluations of algorithms to increase computer recognition of input and cursor
movements. RESULTS: Twenty-four studies had fewer than 10 participants with CP,
with a wide age range of 5 to 77 years. Computer task performance was usually
tested, but only three groups sought participant feedback on ease and comfort of
use. International standards exist to evaluate effectiveness of non-keyboard
devices, but only one group undertook this testing. None of the study designs
were higher than American Academy for Cerebral Palsy and Developmental Medicine
level IV. INTERPRETATION: Access solutions for individuals with CP are in the
early stages of development. Future work should include assessment of end-user
comfort, effort, and performance as well as design features. Engaging users and
therapists when designing and evaluating technologies to enhance computer access
may increase acceptance and improve performance.
