Background & Aim: The Choice Reaction Time (CRT) is characterized ability to choose from two or more stimuli, and can be trained during upper limb tasks after stroke. The aim of this study was to investigate whether the CRT is modified after a single reaching training session while individuals crossing or not the midline. Methods: This is a cross-sectional study in individuals after stroke. To evaluate the CRT, a monitor it was projected with the stimuli corresponding to each reaching task and the electromyographic signal of upper limb was collected simultaneously. The CRT was estimated verifying the response of stimuli in the channel marker, and the beginning of the electromyographic activity (Figure 1). The motor training of reaching was performed after CRT evaluation using six targets, with a randomized location into five blocks, totaling fifty repetitions in a single session. For statistical analysis was using a student's t-test and Cohen’s D to compare pre- and post-intervention. Results: Seven individuals were included (5 males, 63.14± years, 23.71±5.17 of Mini-mental state examination and Fugl-Meyer of 21.14±8.04). The CRT showed a no significant difference before and after training (p=0.086). When individuals crossed the midline (Figure 2) Cohen’s d showed high clinical relevance (d=1.31) to the compromised limb after training. When participants crossed the midline (Figure 3) there was no significant difference for both limbs, shows a moderate clinical relevance (d=0.6) to the compromised limb. Conclusion: It was concluded the training proposed can decrease the reaching CRT of simpler tasks, that do not cross the midline.
