Brief Summary:
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.

Masking: None (Open Label)
Primary Purpose: Supportive Care
Official Title: Restoration of Bimanual Activities of Daily Living Using a Brain/Neural Hand Exoskeleton (B/NHE) in Hand Paralysis

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

Primary Outcome Measures :
  1. 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. ]
