Clinical Results of Neuroprosthesis Use

Download as a PDF

The following are the reported clinical results of neuroprosthesis use;

  • Clinical trials show improvement in grasping functions in stroke and SCI subjects
  • FES technology facilitates a comfortable and secure grasp that allows the individual to hold and manipulate various objects
  • All except the Bionic Glove were able to facilitate both palmar (power) grasp and lateral (fine) grasp
  • The Handmaster-NMS-1, the BGS system, and the ETHZ-ParaCare neuroprostheses have been applied successfully as rehabilitation tools to restore grasping function in SCI individuals instead of being used as permanent orthotic systems
  • To control the neuroprosthesis, subjects are using either an on-off type of switch or have to apply simple analog sensors to generate desired control commands
  • There is a delay of 1-2 seconds from time command is issued and moment that grasp is executed which restricts the speed that an individual can grasp and release objects
  • Neuroprosthesis for grasping can only be used for slower grasping tasks
  • The most widely used and accepted neuroprostheses for grasping are the Freehand System and the Handmaster-NMS-1 and all of the other neuroprostheses mentioned are mainly used in experimental trials for research purposes.
