The immediate effectiveness of whole-body vibration with the modified push-up position on neurocognitive parameters in overheads athletes with and without scapular dyskinesis

Purpose Scapular dyskinesis is a common problem in athletes, especially overhead sports such as volleyball and basketball. The biomechanical and neurocognitive impairments are involved in the occurrence of the scapular dyskinesis. Based on previous studies about the whole-body vibration (WBV) effects on the athletes training, musculoskeletal injuries and neuromuscular responses, the current study focused on the investigation immediate effectiveness of WBV on neurocognitive parameters (reaction time and anticipatory skill) in overheads athletes with and without scapular dyskinesis. Methods Thirty athletes with ( n = 15) and without ( n = 15) scapular dyskinesis participated in this interventional-observational study. The WBV applied with 30 Hz frequency and 5 mm amplitude in the modified push-up position in two groups. The scapular dyskinesis and neurocognitive parameters were recorded by the Caliper test and the Speed Anticipation Reaction Time (SART) system. Results The Caliper measurement in three positions of arm significantly reduced after the WBV in the athletes with scapular dyskinesis ( P
