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).
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.
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.
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.
本研究旨在系统地回顾已发表的关于使脑瘫（CP）患者能够或增强其自我导向计算机访问的设备和技术的开发、使用和有效性的证据。
使用关键词“计算机”、“软件”、“痉挛”、“舞蹈手足徐动症”和“脑瘫”搜索了 9 个电子数据库，并对由此确定的文章的参考文献列表进行了搜索。选择了 30 篇文章进行审查，其中 23 篇报告了设备的开发和可用性测试，7 篇评估了增加计算机对输入和光标运动识别的算法。
24 项研究的 CP 参与者少于 10 人，年龄范围从 5 岁到 77 岁不等。通常测试计算机任务性能，但只有三组参与者对易用性和舒适性提出了反馈。存在评估非键盘设备有效性的国际标准，但只有一组进行了此测试。研究设计没有一个达到美国脑瘫和发育医学学会四级以上水平。
CP 患者的访问解决方案仍处于早期开发阶段。未来的工作应包括评估最终用户的舒适度、努力程度和性能以及设计特点。在设计和评估增强计算机访问的技术时，让用户和治疗师参与其中可能会提高接受度并改善性能。
