Decoding arm speed during reaching [PDF]
Nature Communications, 2018 Brain–machine interfaces typically decode arm velocity from motor cortical neurons to move neuroprostheses, but performance of these devices is degraded by erroneous extraction of speed from the neuronal firing patterns.

Effects of Olfactory Stimuli on Arm-Reaching Duration [PDF]
Chemical Senses, 2008 The aim of the present study was to investigate the effects of olfactory stimuli on visually guided reaching. In Experiment 1, participants reached toward and grasped either a small (almond/strawberry) or a large (apple/orange) visual target. Any 1 of 4 odors corresponding to the visual stimuli or odorless air was administered before movement ...

The Immediate Effect of a Grahamizer Exercise on Arm Reaching in Individuals With Stroke
Physical Therapy Korea, 2020 Background: As technology has progressed, various robot-assisted devices have been developed to reduce therapists’ labor and assist in therapy. However, due to their many limitations, it is more practical to use traditional mechanical devices.

Journal of NeuroEngineering and Rehabilitation, 2023 Background Upper-limb rehabilitation robots provide repetitive reaching movement training to post-stroke patients. Beyond a pre-determined set of movements, a robot-aided training protocol requires optimization to account for the individuals’ unique ...

Hierarchical Control of Visually-Guided Movements in a 3D-Printed Robot Arm
Frontiers in Neurorobotics, 2021 The control architecture guiding simple movements such as reaching toward a visual target remains an open problem. The nervous system needs to integrate different sensory modalities and coordinate multiple degrees of freedom in the human arm to achieve ...

A pilot study into reaching performance after severe to moderate stroke using upper arm support. [PDF]
PLoS ONE, 2018 Stroke effects millions of people each year and can have a significant impact on the ability to use the impaired arm and hand. One of the results of stroke is the development of an abnormal shoulder-elbow flexion synergy, where lifting the arm can cause ...

Unifying Speed-Accuracy Trade-Off and Cost-Benefit Trade-Off in Human Reaching Movements
Frontiers in Human Neuroscience, 2017 Two basic trade-offs interact while our brain decides how to move our body. First, with the cost-benefit trade-off, the brain trades between the importance of moving faster toward a target that is more rewarding and the increased muscular cost resulting ...

Journal of NeuroEngineering and Rehabilitation, 2004 Background Virtual reality (VR) is an innovative tool for sensorimotor rehabilitation increasingly being employed in clinical and community settings. Despite the growing interest in VR, few studies have determined the validity of movements made in VR ...

Reaching in clutter with whole-arm tactile sensing [PDF]
The International Journal of Robotics Research, 2013 Clutter creates challenges for robot manipulation, including a lack of non-contact trajectories and reduced visibility for line-of-sight sensors. We demonstrate that robots can use whole-arm tactile sensing to perceive clutter and maneuver within it, while keeping contact forces low.
