Control of the wrist in three-joint arm movements to multiple directions in the horizontal plane.
In a reaching movement, the wrist joint is subject to inertial effects from proximal joint motion. However, precise control of the wrist is important for reaching accuracy. Studies of three-joint arm movements report that the wrist joint moves little during point-to-point reaches, but muscle activities and kinetics have not yet been described across a range of movement directions. We hypothesiz...
متن کاملInter-joint coupling strategy during adaptation to novel viscous loads in human arm movement.
When arm movements are perturbed by a load, how does the nervous system adjust control signals to reduce error? While it has been shown that the nervous system is capable of compensating for the effects of limb dynamics and external forces, the strategies used to adapt to novel loads are not well understood. We used a robotic exoskeleton [kinesiological instrument for normal and altered reachin...
متن کاملOnline Estimation of Elbow Joint Angle Using Upper Arm Acceleration: A Movement Partitioning Approach
Estimating the elbow angle using shoulder data is very important and valuable in Functional Electrical Stimulation (FES) systems which can be useful in assisting C5/C6 SCI patients. Much research has been conducted based on the elbow-shoulder synergies.The aim of this study was the online estimation of elbow flexion/extension angle from the upper arm acceleration signals during ADLs. For this, ...
متن کاملPersistence of motor adaptation during constrained, multi-joint, arm movements.
We studied the stability of changes in motor performance associated with adaptation to a novel dynamic environment during goal-directed movements of the dominant arm. Eleven normal, human subjects made targeted reaching movements in the horizontal plane while holding the handle of a two-joint robotic manipulator. This robot was programmed to generate a novel viscous force field that perturbed t...
متن کاملDesign of a Human Arm-Like Robot Based on Viscoelasticity of Human Multi-Joint Arm
Knowledge of the human multi-joint arm viscoelastic properties is essential in the assistance of building human-like robots. In this paper, a robust estimation method of human multi-joint arm viscoelasticity during natural movement is reviewed, a human arm-like robot control scheme using the measured viscoelasticity from estimation method is proposed. In order to imitate how to adjust the human...
