Daily-life Brain Control Of A Hand Exoskeleton After Cervical Spinal Cord Injury

A Phase 1 interventional study of BNCI controlled hand exoskeleton in Spinal Cord Injury, sponsored by University Hospital Tuebingen. Completed at 1 site in Spain. Open to participants aged 15 Years to 65 Years. Per ClinicalTrials.gov, last updated 2015-05-14.

Study 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.

Study arms

  • Experimental
    BNCI hand-exoskeleton

    Hand motor function before, during and after application of the device

    Device: BNCI controlled hand exoskeleton

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

06

What researchers measure

Primary outcomes

  1. Change of Toronto Rehabilitation Institute Hand Function Test (TRI-HFT) Score

    The TRI-HFT will be applied once before and while the patients wear the hand exoskeleton

    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.
