Reaction Time and Anticipatory Skill of Overhead Athletes With and Without Scapular Dyskinesia

Purpose: Scapular dyskinesia is a change in position or movement of scapula, which is highly prevalent in athletes with overhead activities. In addition to biomechanical changes in shoulder complex, neurocognitive impairments can have a significant role in its creation. Thus, this study aimed to compare neurocognitive scores between athletes with and without scapular dyskinesia. Methods: In this study, 30 athletes with overhead activities participated. Caliper and SART (Speed Anticipation and Reaction Time) sets were used for assessing subjects’ scapular dyskinesia, reaction time, and anticipation skill. Results: Athletes with scapular dyskinesia had significantly a slower visual and auditory complex choice of reaction time, and a lower auditory choice of reaction time compared to athletes without scapular dyskinesia. Conclusion: No significant difference was seen between two groups in terms of visual choice of react i on time and anticipation skill. Thus, athletes with scapular dyskinesia had poorer performance in more complex neurocognitive tests compared to athletes without it.
