Getting a Grasp on Coordination.
نویسندگان
چکیده
Motor coordination is realized by the nervous system at different levels. Concepts about the coordination within a limb define the controlled parameter in cartesian or joint space, whereas concepts about the coordination between limbs stress the temporal control of schemas. Motor deficits of neurological patients point to the role of the different motor areas in motor coordination.

Spiral me to the core: Getting a visual grasp on text corpora through clusters and keywords
The amount of literature within a research domain is ever growing, thus making it difficult to stay on top of everything. Getting a grasp on the important topics of and areas within a domain or even knowing where to start is often tough and tedious. This paper therefore presents a visualization, that is a cluster spiral, that offers a fast but plain and simple way of exploring the content of la...
متن کاملRobot-assisted evaluation of coordination between grasp and load forces in a power grasp in humans
A novel approach for evaluation of a grasp in humans is presented. The key novelty is combination of a haptic interface with force/torque transducers for measuring the grasp force. This paper presents results of grasp and load force coordination for quasi-static and dynamic external load force disturbances for a power grasp. An elevation of the grasp force is observed in a dynamic task. Elevati...

This paper explores grasping in robot-aided upper extremity rehabilitation, with a special focus on reaching and grasping exercises and the coordination between load force and grasp force. Six healthy subjects and two hemiparetic subjects performed \pick and place"movements with a haptic robot and virtual environment. These movements were segmented into three phases: grasping, transport and rel...
متن کاملNeural coordination during reach-to-grasp.
When reaching to grasp, we coordinate how we preshape the hand with how we move it. To ask how motor cortical neurons participate in this coordination, we examined the interactions between reach- and grasp-related neuronal ensembles while monkeys reached to grasp a variety of different objects in different locations. By describing the dynamics of these two ensembles as trajectories in a low-dim...
متن کاملFeedback device for improvement of coordination of reach-to-grasp after stroke.
OBJECTIVE To describe a novel feedback device (Grasp Rehabilitation Accessory for Stroke Patients [GRASP]) that gives feedback on the time lag between the start of hand opening and the start of transport during reach-to-grasp movements, and to report the results of a preliminary series of single case studies to assess the utility of the device for improving the coordination of arm and hand at t...
