“…Fifteen papers were excluded because they did not provide evidence of testing by individuals with CP [12][13][14][15][16][17][18] or they were evaluations of training or assessment methods rather than technology. [19][20][21][22][23] A further two papers were excluded because of apparently duplicated information: one 24 contained information that appeared identical to a previously published article by another author; 25 the other included results from one patient that had also been summarized in another paper by the same authors with additional participants. 26 A final study was excluded as the full article was not in English.…”

AIM 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.

“…Moreover, based on the aforementioned information obtained from healthy right-handed adults, the performance in persons with disabilities can be further studied for the purpose of substantiating their cursor kinematic characteristics and contributing to support the diagnosis of some populations, such as the patients with cerebellar cortical atrophy and with neglect syndrome researched by Manto et al and Mattingly et al , respectively [ 14 , 15 ]. Furthermore, the development of strategies to remediate or compensate for any disadvantages based on the cursor kinematic characteristics on each direction for persons with disabilities can be considered [ 3 , 5 , 8 – 10 ]. For example, if a patient demonstrates a disadvantage while moving towards the left, we can relocate the icons from the left side to the right side on the screen desktop, then the demands to move the cursor leftwards will be much less and this patient can perform more functionally.…”

“…For the upwards and downwards movements, participants moved from the point (500, 699) to (500, 19) and from the point (500, 19) to (500, 699), respectively. Moreover, this apparatus and measurement program were also successfully used in a single subject experimental research design, to study the effect of direction on cursor moving kinematics with a trackball mouse, with significant improvement in the cursor reaching and stabilization on the toolbar area [ 5 , 8 ].…”

There have been only few studies to substantiate the kinematic characteristics of cursor movement. In this study, a quantitative experimental research method was used to explore the effect of moving direction on the kinematics of cursor movement in 24 typical young persons using our previously developed computerized measuring program. The results of multiple one way repeated measures ANOVAs and post hoc LSD tests demonstrated that the moving direction had effects on average velocity, movement time, movement unit and peak velocity. Moving leftward showed better efficiency than moving rightward, upward and downward from the kinematic evidences such as velocity, movement unit and time. Moreover, the unique pattern of the power spectral density (PSD) of velocity (strategy for power application) explained why the smoothness was still maintained while moving leftward even under an unstable situation with larger momentum. Moreover, the information from this cursor moving study can guide us to relocate the toolbars and icons in the window interface, especially for individuals with physical disabilities whose performances are easily interrupted while controlling the cursor in specific directions.

“…Another major barrier is the lack of a universal and comprehensive computer access assessment [13]. Although many different systematic assessments for computer access have been proposed [8,[14][15][16], none have been widely adopted. In many instances, finding a successful access solution for a particular individual remains a trial and error process, because of the 'lack of a valid predictive model' to guide device selection [10].…”
