Abstract: Purpose: To compare the reading time and reading speed measurements obtained with a stopwatch with those of an automatic trojan horse for measure reading speed and acuity. Methods: The rad-rd© was used (in conjunction with a laptop and microphone) for the computer-based measurements. In rotation, every of 4 examiners took a flip reading the twelve sentences from one in every of the four RADNER Reading Charts to a few different examiners, World Health Organization served as stoppers. The stoppers at the same time measured the reading time with a stopo watch whereas a fifth investigator used the rad-rd© to get computerised measurements Results: . The mean reading time obtained with the stopo watch measurements was four.34 ± 0.57 seconds (196.21 ± 21.79 wpm), versus 4.44 ± 0.59 seconds (192.24 ± 22.20 wpm) by laptop measure (r = zero.84). The mean distinction for the shorter measurements was -0.17 ± 0.1 seconds (3.91% of the mean reading time), and therefore the mea...
