Brain/Neural Hand Exoskeleton Control for Restoration of Bimanual Tasks

June 18, 2020 updated by: University Hospital Tuebingen

Restoration of Bimanual Activities of Daily Living Using a Brain/Neural Hand Exoskeleton (B/NHE) in Hand Paralysis

This study investigates whether spinal cord injury and stroke survivors (n=10) are able to operate a brain/neural hand exoskeleton (B/NHE) based on electroencephalography (EEG) and electrooculography (EOG) for restoration of bimanual activities of daily living (ADLs). To assess bimanual ADLs, the Berlin Bimanual Task Assessment (BEBITA) will be applied. Improvements in BEBITA will be evaluated with and without B/NHE use.

  • interval since stroke at least 6 months
  • substantial motor deficit with:
  • Medical Research Council (MRC) -score of less than 2 out of 6 possible points (0=no activity; 1=visible contraction without motor effect; 2=movements with elimination of gravity; 3=movements against gravity; 4=movements against weak resistance; 5=normal force)
  • Fugl-Meyer Test (upper extremity) of less than 31 points, "no to little mobility"

Inclusion Criteria (Spinal Cord Injury):

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Brain/neural hand exoskeleton (B/NHE)
The brain/neural hand exoskeleton restores hand motor function by translating user's intention into grasping motions

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
Change in Berlin Bimanual Task Assessment (BEBITA) score
Time Frame: Hand function will be assessed twice on the same day. Once before the hand exoskeleton is applied (absence of the assistive device) and once after the brain-controlled hand exoskeleton was attached to the patients' hand and arm.
