Accurate hand movement assistance

摘要

Hand movement assistance apparatus of both the active and passive types and usable for movement stabilization by either a normal human subject seeking to perform a task of great precision or a neurologically impaired human subject having Parkinson's disease or similar dysfunction. Both the active and passive apparatus provide a glove-like receptacle for the subject's hand; the passive system applies closed-loop feedback system generated forces to the glove and the active system provides a hand guidance track arrangement for the subject's hand. Three axis stabilization forces and rotationally oriented forces are alternatively provided by the active system, along with responses particularly adopted to the Parkinson's tremor frequency.
