Influence of foot position and vision on dynamic postural strategies during the “grand plié” ballet movement (squatting) in young and adult ballet dancers

The effect of foot position was greatest with EO. The parallel position was less stable. The YD were more unstable in the parallel position, particularly with EC. For both groups, the lack of vision increased instability. These results show the importance of integrating balance training in a variety of foot positions and visual conditions, particularly during the initial stages of training to prevent injury.
