About this trial

This is a single-cohort early feasibility trial to determine whether an investigational device called the Bidirectional Neural Bypass System can lead to the restoration of movement and sensation in the hand and wrist of up to seven individuals with tetraplegia.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Males and females between 22 and 65 years of age

Individuals with a stable cervical spinal cord injury that have International Standards for the Neurological Classification of SCI (ISNCSCI) motor scores for fingers of 0 - 2 (non-functional) and ISNCSCI sensory scores of 0 - 2 (not normal) on the palmar side

Individuals at least one year from initial spinal cord injury

Individuals that are considered English Proficient due to the study requirements to follow verbal commands during testing sessions

Disqualifiers

Individuals participating in another research study that may affect the conduct or results of this study

Medical contraindications for diffusion tensor imaging, functional magnetic resonance imaging, electromyography, computed tomography, cortical stimulation, or craniotomies/surgeries

Prior difficulties or allergy to general anesthesia

Active wound healing or skin breakdown issues

Trial design

Design model

Single group

Treatments tested in this trial

  • Bidirectional Neural Bypass System

    Device

    These participants will receive the investigational device called the Bidirectional Neural Bypass System. The study intends to use this device to restore volitional movement and sensation to the hand and wrist of an individual during its use in the laboratory.

Trial outcomes

Primary outcomes

1

Restoration of Movement

The primary outcome of restoring movement will be evaluated through Graded Redefined Assessment of Strength, Sensibility \& Prehension. The performance will be graded on a numeric scale from 0-92, where a higher number indicates a better outcome. Participants will complete 10 distinct arm, wrist, and finger movements. The movements will be evaluated on a 5-point scale ranging from no movement to normal movement for a total of 0-50. Participants will be asked to perform a cylindrical grasp, key pinch, and a thumb-index pinch. The movements will be evaluated on a 4-point scale ranging from an inability to position wrist and fingers to able to perform movement with normal force for a total of 0-12. Participants will be asked to pour water, unscrew lids, place pegs on a board, open a lock, drop coins in a slot, and screw nuts. The movements will be evaluated on a 5-point scale ranging from 0% completed to 100% completed with expected grasp and no difficulties for a total of 0-30.

Time frame
The primary outcome will be assessed over the course of 48 months during the study's restoration sessions.
2

Restoration of Sensation

The primary outcome of restoring the perception of tactile sensation of the hand will be evaluated through the 5-Point Likert Scale. Participants will be asked whether they perceive sensation in response to objects being placed against the hand and fingertips. Participants will indicate whether they feel the object by selecting either strongly disagree (1), disagree (2), neutral (3), agree (4), or strongly agree (5). A higher total response score indicates an improvement in outcome.

Time frame
The primary outcome will be assessed over the course of 48 months during the study's restoration sessions.
