Abstract

Objective: To determine the need, per the Halstead Reitan instructions, to achieve five trials within five taps on finger oscillation. We hypothesized there would be no significant difference when greater than five trials were completed. Method: Participants were 71 patients referred for evaluation; 54% were Caucasian and 41% Hispanic. Average age was 43 (SD = 12.8); average education was 12.7 (SD = 3.2). Results: Wilcoxon Signed Ranks tests were used due to the paired nature of the data, as well as it having significant negative skew. Mean taps with the dominant hand (DH) of all participants using the traditional scoring method was 45.0 (SD = 9.7), and 41.9 with the non-dominant hand (NDH; SD = 8.4). Of the 71 participants, 72% had > 5 trials with the DH and 54% with the NDH. The average of the first five trials of those with > 5 taps was 45.1 with the DH (SD = 9.3) and 43.7 with the NDH (SD = 8.0). There was no statistically significant difference between the mean of the first five trials and traditional scoring for either the dominant (z = −1.8, p = .07) or non-dominant hand (z = −.302, p = .76). Conclusion(s): Despite the original scoring method requiring five trials within five taps, current results indicate finger tapping can be discontinued after five trials regardless of inter-trial variability. These results imply testing can be shortened slightly, reducing examinee fatigue and stress for the examiner, who oftentimes has to fill a multitude of 1- to 2-minute rest breaks.
