Problem statement: The purpose of this investigation was to examine the effects of increased physiological arousal on the ability to perceive upper extremity positional awareness in healthy young adults. Approach: Thirty-eight participants were pre- and post-tested for upper extremity positional awareness using a manual kinesthesiometer. Participants in the experimental group underwent a combination of the Stroop color-word task and timed arithmetic problems to produce a state of physiological arousal. Heart rate and blood pressure measurements were taken during data collection to assess levels of physiological arousal. Pre-and post-test absolute error scores for each participant were compared. Results: ANCOVA revealed a significant time effect (p<0.046) between pre and post-test trials for the experimental group. Conclusion: The results suggested positional awareness is altered under a state of elevated physiological arousal and that these results may have significant implications for individuals performing various types of motor skills.
