Foot-targeting in reaching and grasping
SPARROW WA; VAN DER KAMP J; SAVELSBERGH GJP
GAIT POSTURE , 2003, vol. 18, n° 1, p. 60-68 Doc n°: 109794 Localisation : Documentation IRR Descripteurs : DE82 - EXPLORATION EXAMENS BILANS - PIED, DF22 - EXPLORATION EXAMENS BILANS - MARCHE Foot positioning was investigated when right-handed (Experiment One) and left handed adults (Experiment Two) stopped walking to grasp a stationary 70 min ball at shoulder height. In both experiments centroid location formed by the toe and heel coordinates relative to the object was highly consistent within a target-location condition, demonstrating a foot-targeting phenomenon. Centroid location in the anterior-posterior direction was uninfluenced by grasping hand but the centroid shifted right for left hand grasps and left for right hand grasps. With the target either centrally located or on the same side as the dominant hand, foot positioning brought the grasping hand closer to the target in the medial-lateral direction. When the target object was aligned with the shoulder opposite the dominant hand both groups adopted foot positions to the left of the target. Thus, neither group adopted optimal foot position when the target was located opposite their dominant hand. Foot orientation angle relative to the target was also influenced by choice of grasping hand. Collectively, the findings demonstrate a close association between grasping hand and foot position when approaching to reach and grasp an object but also suggest that foot-dominance may influence medial-lateral centroid location.
