Influence of Anthropometric Height on Oculo-Manual Coordinative Reaction Time

<b>Objectives:</b> This work investigated the influence of anthropometric height on oculo-manual ability during a visuo-motor reaction time task. The aim was to determine whether aligning test configurations with individual stature changes performance outcomes. <b>Methods:</b> In the first phase, 450 participants completed a standardized reaction task using a fixed panel, and correlations were explored between anthropometric measures and performance. The results revealed significant inverse correlations between height and both reaction time total time, and reaction time intertime. A second experimental phase involved an additional group of 36 individuals, who completed the same task using both the fixed and adjustable panels, designed to align visual stimuli with each participant's central line of sight and arm length. <b>Results:</b> A paired-sample <i>t</i>-test showed a statistically significant reduction in both reaction time total time, total time required to deactivate all 54 lights targets, (32.1±3.26 s to 30.7±2.58 s, p<0.05) and reaction time intertime, average time interval between successive light deactivations out of a total of 54 lights, (0.31±0.123 s to 0.21±0.149 s, p<0.01), time total time, total time required to deactivate all 54 lights targets, (32.1±3.26 s to 30.7±2.58 s, p<0.05) and reaction time intertime, average time interval between successive light deactivations out of a total of 54 lights, (0.31±0.123 s to 0.21±0.149 s, p<0.01) under the adjustable panel configuration. <b>Conclusions:</b> These findings suggest that standard testing configurations may disadvantage individuals with shorter stature and highlight the benefits of personalized setups for assessing and enhancing oculo-manual coordination.
