Robot-Aided Mapping of Wrist Proprioceptive Acuity across a 3D Workspace. [PDF]
PLoS ONE, 2016 Proprioceptive signals from peripheral mechanoreceptors form the basis for bodily perception and are known to be essential for motor control. However we still have an incomplete understanding of how proprioception differs between joints, whether it ...

Model-based analysis of the stiffness of the wrist joint in active and passive conditions
bioRxiv, 2018 The control of joint stiffness is a fundamental mechanism used to control human movements. While many studies have observed how stiffness is controlled for tasks involving shoulder and elbow motion, a limited amount of knowledge is available for wrist ...

Constrained Registration of the Wrist Joint [PDF]
IEEE Transactions on Medical Imaging, 2009 Comparing wrist shapes of different individuals requires alignment of these wrists into the same pose. Unconstrained registration of the carpal bones results in anatomically nonfeasible wrists. In this paper, we propose to constrain the registration using the shapes of adjacent bones, by keeping the width of the gap between adjacent bones constant. The

Frontiers in Bioengineering and Biotechnology, 2023 Background: Total wrist arthroplasty is an effective treatment for end-stage wrist arthritis from all causes. However, wrist prostheses are still prone to complications such as prosthesis loosening and periprosthetic fractures after total wrist ...

Minimizing endpoint variability through reinforcement learning during reaching movements involving shoulder, elbow and wrist. [PDF]
PLoS ONE, 2017 Reaching movements are comprised of the coordinated action across multiple joints. The human skeleton is redundant for this task because different joint configurations can lead to the same endpoint in space.
