Improving Motor Function After Spinal Cord Injury
Spinal Cord Injury
About this trial
This is an interventional treatment trial for Spinal Cord Injury focused on measuring spinal cord injury, neural control, motor function, hand movement
Eligibility Criteria
Inclusion Criteria:
Male and female Veterans and non Veterans with spinal cord injury at least 6 months after injury was sustained. The investigators also plan to enroll control subjects who do not have any history of spinal cord injury.
Participants who are unimpaired healthy controls:
- Male and females between ages 18-85 years
- Right handed
- Able to complete precision grips with both hands
- Able to complete full wrist flexion-extension bilaterally
- Able to walk unassisted
- Able to complete full ankle flexion-extension bilaterally
Participants who have had a spinal cord injury:
- Male and females between ages 18-85 years
- Chronic SCI ( 6 months of injury)
- Spinal Cord injury at or above L5
- The ability to produce a visible precision grip force with one hand
- Individuals who have the ability to pick up a small object (large paperclip) from a table independently
- Able to perform some small wrist flexion and extension (measured by a goniometer)
- The ability to perform a small visible contraction with dorsiflexor and hip flexor muscles
- No subjects will be excluded based on their race, religion, ethnicity, gender or HIV status.
Exclusion Criteria:
Exclusion criteria for enrollment For SCI and Healthy Control Subjects (for stimulation):
- Uncontrolled medical problems including pulmonary, cardiovascular or orthopedic disease
- Any debilitating disease prior to the SCI that caused exercise intolerance
- Premorbid, ongoing major depression or psychosis, altered cognitive status
- History of head injury or stroke
- Metal plate in skull
- History of seizures
- Receiving drugs acting primarily on the central nervous system, which lower the seizure threshold (see appendix 2)
- Pregnant females
- Ongoing cord compression or a syrinx in the spinal cord or who suffer from a spinal cord disease such as spinal stenosis, spina bifida, MS, or herniated cervical disk
- Individuals with scalp shrapnel, cochlear implants, or aneurysm clips.

Active Comparator
Motor task+ Magnetic stimulation
rTMS/sham rTMS
Training + rTMS/ Sham rTMS
Participants will be asked to complete a precision grip with the index and thumb finger at the same time as flexing or extending the wrist. magnetic stimulation to the brain will be administered and measurements will be taken during movement.
Participant will be randomly assigned to one of 3 groups: repetitive transcranial magnetic stimulation (rTMS), sham (fake) rTMS, or sham (fake) rTMS over control brain area will be administered to the brain. the stimulation will be targeting finger and wrist muscles during movement.
Participants will be asked to follow a target line on the computer as accurately as possible while performing precision grips or foot movement . Magnetic stimulation will be given during rest and movement.
