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

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. 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. 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. 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.
