Prehension is the act of coordinated reaching and grasping. Wallace, Stevenon, Spear, Weeks (1994) proposed to assess the stability of this coordination by scanning the dynamics of prehension. The scanning method proposed by these authors prompted participants to position their peak hand aperture at different locations along the trajectory. Comparing the actual performance with the required performance, Wallace and colleagues concluded that there was a single stable pattern of coordination. Albeit different for each individual. Here, we show that the method developed by Wallace et al. (1994) and later used by Button, Bennett, Davids (1998) was flawed. We propose two potential fixes to the method and report a replication of the original experiment.
