Age-related changes in multi-finger interactions in adults during maximum voluntary finger force production tasks.
This study aimed to continue our characterization of finger strength and multi-finger interactions across the lifespan to include those in their 60s and older. Building on our previous study of children, we examined young and elderly adults during isometric finger flexion and extension tasks. Sixteen young and 16 elderly, gender-matched participants produced maximum force using either a single ...
متن کاملFinger 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 کاملSensory Feedback Modulates Maximum Voluntary Force in Multi-finger Pressing
The human hand is an excellent example of an effector capable of producing a wide range of forces for everyday manipulation tasks such as pressing, grasping and rotating objects. Both maximal and sub-maximal forces are essential for dexterous manipulation, and sensory feedback plays a critical role in successful completion of such tasks. While the role of sensory feedback in conducting sub-maxi...
متن کاملMulti-Finger Interaction and Synergies in Finger Flexion and Extension Force Production
The aim of this study was to discover finger interaction indices during single-finger ramp tasks and multi-finger coordination during a steady state force production in two directions, flexion, and extension. Furthermore, the indices of anticipatory adjustment of elemental variables (i.e., finger forces) prior to a quick pulse force production were quantified. It is currently unknown whether th...
