Brief Summary:
This study is to determine if non-invasive electrical stimulation of the spinal cord can be used to: 1) assess spared function following a spinal cord injury; and 2) be use for rehabilitation.

Condition or disease Intervention/treatment Phase
Spinal Cord Injury Device: Transcutaneous Electrical Spinal Cord Stimulation Not Applicable

Detailed Description:

This study is to determine if non-invasive electrical stimulation of the spinal cord can be used to: 1) assess spared function following a spinal cord injury; and 2) be use for rehabilitation.

The investigators hypothesize that this type of stimulation can be used to locate and determine if any spinal (nerve) pathways or connections were spared following a spinal cord injury. We also hypothesize the same stimulation can help revive or recover function to muscles connected to these spared spinal (nerve) pathways in individuals who are clinically paralyzed. Our research has demonstrated that modifying the activation state of the spinal cord after an injury, or awakening the spinal cord, can benefit people with paralysis years after a spinal cord injury. This method and device have not yet been approved by the FDA for the treatment of paralysis and are under investigation. This study if successful will help provide further evidence that could be use to one day to gain FDA approval.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Sham Comparator: Grp#1: sham stimulation

Group #1: Baseline clinical assessment; followed by two weeks training with no stimulation; then four weeks training + sham Transcutaneous Electrical Spinal Cord Stimulation; followed by repeat clinical assessment; then four weeks training + effective non-sham Transcutaneous Spinal Cord Stimulation; repeat clinical assessment.

Secondary outcome measurements: assess ability to stand with and without stimulation using a stance frame support; assess trunk function (core stability) with and without stimulation

 Device: Transcutaneous Electrical Spinal Cord Stimulation
A prototype device that non-invasively delivers electrical stimulation to the spinal cord will be used to assess and rehabilitate spared spinal cord function.
Other Name: Prototype Device
Active Comparator: Grp#2: Control

Group #2: Baseline clinical assessment; followed by two weeks training with no Transcutaneous Electrical Spinal Cord Stimulation; then four weeks training + effective Transcutaneous Electrical Spinal Cord Stimulation; followed by repeat clinical assessment.

Secondary outcome measurements: assess ability to stand with and without stimulation using a stance frame support; assess trunk function (core stability) with and without stimulation

 Device: Transcutaneous Electrical Spinal Cord Stimulation
A prototype device that non-invasively delivers electrical stimulation to the spinal cord will be used to assess and rehabilitate spared spinal cord function.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Improvement in sensorimotor function in the lower extremities [ Time Frame: 10-12 weeks ]

    Subjects will be tested by several measures of sensory and motor function, as well as self assessments of spasticity, quality of life, and independence. These tests include:

    American Spinal Injury Association (ASIA) scoring system, Spinal Cord Independence Measure (SCIM), Ashworth Spasticity Scale, Penn Spasm Frequency, Visual Analog Scale (VAS) for Spasticity, Electromyographic (EMG) recordings, Joint angle (goniometer) measures, kinematic analysis.



Secondary Outcome Measures :
  1. Ability to stand independently [ Time Frame: 2-4 weeks ]
    Subjects will be evaluated on their core body function and ability to stand
