- Does a basic deficit in force control underlie cerebellar ataxia?Steven K Charles
Department of Mechanical Engineering, The Johns Hopkins University, Baltimore, Maryland, USA
J Neurophysiol 109:1107-16. 2013..Thus a fundamental cerebellar operation may be combining/coordinating degrees of freedom across many kinds of movements and behaviors...
- Stiffness, not inertial coupling, determines path curvature of wrist motionsSteven K Charles
Harvard MIT Division of Health Sciences and Technology, Cambridge, Massachusetts, USA
J Neurophysiol 107:1230-40. 2012..This requires humans to predict and compensate for wrist dynamics, but, unlike reaching, nonlinear inertial coupling (e.g., Coriolis acceleration) is insignificant. The dominant term to be compensated is wrist stiffness...
- Dynamics of wrist rotationsSteven K Charles
Department of Mechanical Engineering, Brigham Young University, 435 Crabtree Building, Provo, UT 84602, USA
J Biomech 44:614-21. 2011....
- The curvature and variability of wrist and arm movementsSteven K Charles
Harvard MIT Division of Health Sciences and Technology, Cambridge, MA, USA
Exp Brain Res 203:63-73. 2010..We provide evidence indicating that this type of systematic pattern is not likely caused by noise or other neural causes, but may be explained by the unique biomechanics of the wrist...
- Robot-aided neurorehabilitation: a robot for wrist rehabilitationHermano Igo Krebs
Department of Mechanical Engineering, Massachusetts Institute of Technology, Cambridge, MA 02139, USA
IEEE Trans Neural Syst Rehabil Eng 15:327-35. 2007..Here, we report on the initial results on 36 of these volunteers. These results demonstrate that further improvement should be expected by adding additional training to other limb segments...
