Detailed Description

Spinal cord injury (SCI) is an insult to the spinal cord resulting in a change, either temporary or permanent, in its normal motor, sensory, and/or autonomic function. It is estimated that the annual incidence of spinal cord injury (SCI), not including those who die at the scene of the accident, is approximately 40 cases per million population in the U. S. or approximately 12,000 new cases each year. The purpose of this study is to demonstrate high definition non-invasive neuromuscular stimulation of an upper extremity in tetraplegic participants. This study will plan to enroll up to 15 subjects who have been diagnosed with tetraplegia. The total duration of the study is expected to be about 18 months, and each participant is expected to be on the study for about 6 months. The study design will consist of the following two (2) phases listed below. I. Baseline assessment and calibration (approximately 1 month) II. Testing motions: pre-sequenced and EEG-triggered motions; further calibration as needed (approximately 5 months) Phase I – Baseline – Medical history review – Physical and neurological exam – EMG – Fit and calibrate external stimulator: The Battelle Neuromuscular Stimulator will be setup and calibrated to evoke wrist and hand/finger movements. Phase II – Testing Motions After the Neuromuscular Stimulator is setup and calibrated, various spatial and temporal stimulation patterns will be tested to evoke wrist/hand movements in various sequences of individual and combined movements.

Interventions

  • Device: Neuromuscular Stimulator

Arms, Groups and Cohorts

  • Experimental: Neuromuscular Stimulator
    • Neuromuscular Stimulator is setup and calibrated, various spatial and temporal stimulation patterns will be tested to evoke wrist/hand movements in various sequences of individual and combined movements.

Clinical Trial Outcome Measures

Primary Measures

  • Change in Voluntary Movement
    • Time Frame: through study completion, up to 60 months
    • consistent and repetitive voluntary movement in the targeted muscle groups as assessed by investigator(s)- no formal scale is used. The participant(s) started out with paralysis due to spinal cord injury, so any active voluntary movement consists of a qualitative change in movement.

Secondary Measures

  • Change in Functional Movement
    • Time Frame: through study completion, up to 60 months
    • consistent movement in the targeted muscle groups that is functional (manipulate or pick up an object); as assessed by investigator(s) for task completion- no formal scale used Objects were taken from the Action Research Arm Task, Grasp and Release Task, GRASSP as well as using household objects (phone, cup, spoon)
