To determine whether the number of words displayed in the word prediction software (WPS) list affects text input speed (TIS) in people with cervical spinal cord injury (SCI), and whether any influence is dependent on the level of the lesion.
A cross-sectional trial.
A rehabilitation center.
Persons with cervical SCI (N=45). Lesion level was high (C4 and C5, American Spinal Injury Association [ASIA] grade A or B) for 15 participants (high-lesion group) and low (between C6 and C8, ASIA grade A or B) for 30 participants (low-lesion group).
TIS was evaluated during four 10-minute copying tasks: (1) without WPS (Without); (2) with a display of 3 predicted words (3Words); (3) with a display of 6 predicted words (6Words); and (4) with a display of 8 predicted words (8Words).
During the 4 copying tasks, TIS was measured objectively (characters per minute, number of errors) and subjectively through subject report (fatigue, perception of speed, cognitive load, satisfaction).
For participants with low-cervical SCI, TIS without WPS was faster than with WPS, regardless of the number of words displayed (P<.001). For participants with high-cervical SCI, the use of WPS did not influence TIS (P=.99). There was no influence of the number of words displayed in a word prediction list on TIS; however, perception of TIS differed according to lesion level.
For persons with low-cervical SCI, a small number of words should be displayed, or WPS should not be used at all. For persons with high-cervical SCI, a larger number of words displayed increases the comfort of use of WPS.
确定单词预测软件（WPS）列表中显示的单词数量是否会影响颈脊髓损伤（SCI）患者的文本输入速度（TIS），以及这种影响是否取决于损伤水平。
横断面试验。
一家康复中心。
颈脊髓损伤患者（N = 45）。15名参与者（高位损伤组）的损伤水平较高（C4和C5，美国脊髓损伤协会[ASIA] A级或B级），30名参与者（低位损伤组）的损伤水平较低（C6至C8之间，ASIA A级或B级）。
在四项10分钟的抄写任务中评估TIS：（1）不使用WPS（无）；（2）显示3个预测单词（3个单词）；（3）显示6个预测单词（6个单词）；（4）显示8个预测单词（8个单词）。
在4项抄写任务中，客观测量TIS（每分钟字符数、错误数量），并通过受试者报告主观评估（疲劳、速度感知、认知负荷、满意度）。
对于低位颈脊髓损伤患者，无论显示的单词数量如何，不使用WPS时的TIS比使用WPS时更快（P <. = 001）。对于高位颈脊髓损伤患者，使用WPS对TIS没有影响（P =.99）。单词预测列表中显示的单词数量对TIS没有影响；然而，TIS的感知因损伤水平而异。
对于低位颈脊髓损伤患者，应显示少量单词，或者根本不使用WPS。对于高位颈脊髓损伤患者，显示更多的单词可提高WPS的使用舒适度。
