The studies presented in Table 1 highlight the lack of data regarding the influence of participant’s characteristics on TIS. A summary of the studies evaluating TIS is provided in Table 1, which is classified according to the pathologies and devices studied. In addition, (i) the samples are usually very small (ii) the computer access devices used very different and (iii) some important methodological aspects are not specified. Many studies have been carried out to evaluate TIS 5, 7, 8 however, all of them have important limitations: first, the pathologies 10 (both sensory and motor impairments such as locked-in syndrome, neuromuscular disorders and cervical SCI) and the severity of sensory–motor impairment 11 (pooled results of assessments with persons with different motor function capacities) evaluated are quite heterogeneous. 9 In the literature, it is very difficult to find specific data regarding TIS for persons with cervical SCI, particularly for those with high levels of SCI (C5 or above, Asia A or B). However, despite the development of these different devices, text input speed (TIS) remains lower for people with sensory motor impairments than for able-bodied people. Speech recognition devices are also an option for both groups. Special devices such as trackballs and touchpads can be fitted to standard hardware to control the mouse cursor. This group may be able to use a standard keyboard with hand splints, or to press keys with the metacarpophalangeal joint of the little finger using forearm supination. The second functional group includes those whose injury level is at or below C6 Asia A and B. The mouse cursor can be controlled by head tracking devices involving video or infrared cameras, 4 and for text input, mouthsticks 5, 6 can be used with a standard keyboard or pointing devices with an on-screen keyboard. To access a computer, this group requires assistive devices that are operated by head movements.

3 The first group includes those whose injury level is at or above C5. 2 Persons with cervical SCI Asia A and B can be classified into two functional groups. Depending on the level of the lesion, different devices exist to facilitate computer access.

The use of technological devices such as computers is often essential for the social and professional integration of persons with cervical spinal cord injury (SCI) 1 however, they can be difficult to access.

The results showed that only the type of computer access device influenced TIS. This is the first study to analyze TIS in a group of participants with cervical SCI.

Surprisingly, none of the person’s characteristics, including the level of cervical lesion, affected TIS. The Scheirer–Ray–Hare test showed that only the type of computer access device significantly influenced TIS. and of those with lesions below C5 was 10 (9 18) w.p.m. Median TIS of participants with lesions at or above C5 was 12 (4 13) w.p.m. Median TIS of participants with cervical SCI was 9 (6 14) words per minute (w.p.m.) and of able-bodied participants was 19 (14 24) w.p.m. Thirty-five participants with cervical SCI and 21 able-bodied people were included. The relationship between the characteristics of participants with cervical SCI, type of computer access device and TIS were analyzed using a Scheirer–Ray–Hare test (nonparametric test similar to a two-way analysis of variance). TIS was evaluated during a 10- min copying task. Each participant underwent a single evaluation using their usual computer access devices. In addition, able-bodied people were recruited from the hospital staff. People with cervical SCI were included if their level of injury was between C4 and C8 Asia A or B, and if they were computer users.

This study was conducted in the Rehabilitation Department, Garches, France. The objectives of this study were to determine text input speed (TIS) in persons with cervical spinal cord injury (SCI) and to study the influence of personal characteristics and type of computer access device on TIS.
