Spinal Cord Injury
Conditions
Brief summary
In this study, 6 volunteer participants with chronic spinal cord injury will be invited to use an autonomous hand exoskeleton device controlled by a brain/neural-computer interaction (BNCI) system fusing electroencephalography (EEG) and electrooculography (EOG) to detect the intention of the user to grasp objects of daily life. The BNCI system consists of a lightweight hand exoskeleton connected to portable motors, rechargeable batteries and a computerized control system integrated into a wheelchair. Before, during and after use of the BNCI system the volunteers will perform standardized assessments and complete questionnaires to assess the functional and psychological effects of the exoskeleton. Functional outcomes primarily focus on motor function in performing daily life actions while psychological outcomes primarily focus on safety, reliability as well as predisposition and perceptions of disability.
Interventions
DEVICEBNCI controlled hand exoskeleton
The BNCI system fuses and translates bio-signals related to user intention into control signals of an assistive device performing grasping motions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of Toronto Rehabilitation Institute Hand Function Test (TRI-HFT) 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. | The TRI-HFT will be applied once before and while the patients wear the hand exoskeleton |
