NCT04440709

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.

Outcome Measures

Primary Outcomes (1)

  • Change in Berlin Bimanual Task Assessment (BEBITA) score

    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.

Study Arms (1)

Brain/neural hand exoskeleton (B/NHE)

EXPERIMENTAL
Device: Brain/neural hand exoskeleton (B/NHE)

Interventions

The brain/neural hand exoskeleton restores hand motor function by translating user's intention into grasping motions

Eligibility Criteria

Age18 Years - 68 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • single ischemic or hemorrhagic insult with subcortical lesion (medullary canal, internal capsula, pedunculi cerebri)
  • 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"
  • cervical spinal cord injury, height C5-C6
  • interval after spinal cord injury at least 6 months
  • substantial motor deficit with American Spinal Cord Association (ASIA) -Classification B or C (A=no muscle function/sensitivity below the spinal cord injury; B=no muscle function, limited sensitivity present; C=low non-relevant muscle function, sensitivity present; D=functionally relevant muscle functions present; E=fully preserved or restored functions)

You may not qualify if:
