Finger force vectors in multi-finger prehension.
In a majority of studies on grasp, only normal forces were measured and only when a zero torque was exerted on a hand-held object. This study concerns finger force vectors during the torque production tasks. Subjects (n=8) stabilized a handle with an attachment that allowed for change of external torque from -1.5 to 1.5 Nm. Forces and moments exerted by the digit tips on the object were recorde...
متن کاملPrehension synergy: effects of static constraints on multi-finger prehension.
Previous studies have shown that the interactions of human hand digits are influenced by internal constraints, i.e., biomechanical and central constraints. However, little is currently known about the influence of externally imposed mechanical constraints on multi-finger behavior. This study investigates maximal digit force production during fixed object and free object prehension in statics. T...

متن کاملMulti-finger Prehension Synergy: Exploration with Transcranial Magnetic Stimulation
The control of hand action is commonly viewed as based on a two-level hierarchy (Arbib et al. 1985): (1) The task is shared between the thumb and a virtual finger (VF, an imagined digit with the mechanical effect equal to that of the four fingers); and (2) VF action is shared among the actual fingers. Synergies at both levels can be studied as patterns of co-variation of its elements that stabi...
متن کاملAge-related changes in the control of finger force vectors.
We explored changes in finger interaction in the process of healthy aging as a window into neural control strategies of natural movements. In particular, we quantified the amount of force produced by noninstructed fingers in different directions, the amount of force produced by the instructed finger orthogonally to the task direction, and the strength of multifinger synergies stabilizing the to...
