Impact de l’utilisation d’aides techniques d’accès à l’outil informatique sur la vitesse de saisie de texte pour les personnes atteintes de tétraplégie

Summary :

Introduction. Individuals with cervical spinal cord injury (SCI) have difficulty accessing computers through conventional methods (e.g., standard keyboard and mouse).
Aim. The purpose of this paper was to provide a critical narrative review on types of computer access devices and word predic-tion software for individuals with cervical SCI.
Methods. A search was conducted in several electronic databases.
Results. There is limited data about Test Input Speed (TIS) in people with cervical SCI. One study showed that TIS in individuals with cervical SCI was significantly lower (mean = 11 words per minute (wpm)) (p=0.001) than TIS of abled-bodied individuals (19 wpm). In a sample of individuals with cervical SCI, there was a statistically significant difference between voice recognition system (mean = 18 wpm), a standard keyboard (mean = 8 wpm) and an onscreen keyboard (mean = 3 wpm) (p<0.001). However, the literature suggested that the impact of Word Prediction Software (WPS) for increasing TIS remains questionable. Indeed, there is limited scientific documentation of the influence of the parameters of WPS on TIS. To date, results suggest that for individuals with low-cervical SCI the number of words displayed in the prediction list should be low (e.g., 3 words) or WPS should not be used at all. For persons with high-cervical SCI, a larger number of words displayed in the prediction list may increase users comfort with WPS. In both diagnostic groups, WPS did not increase TIS. For the parameter “frequency of use”, use of WPS with the activation of frequency of use increased TIS in participants with high-level tetraplegia. For participants with low-level tetraplegia, the use of WPS with frequency of use activated only decreased the number of errors. Conclusion. Research on development and optimization of computer access devices and its application to clinical practice is needed. Each professional could provide clear and accurate information on the benefits of WPS for people with cervical SCI. WPS must be set regarding the needs of people with cervical SCI. If not, the use of these software’s may go against the ex-pected benefits.
