About this study
The purpose of this study is to examine the relationship between common clinical assessments and measurements of the function of brain-spinal cord-muscle connections, and to examine the effects of training a brain-spinal cord-muscle response in individuals with incomplete spinal cord injury. A transcranial magnetic stimulator (TMS) is used for examining brain-to-muscle pathways. This stimulator produces a magnetic field for a very short period of time and indirectly stimulates brain cells with little or no discomfort. The target muscle is the wrist extensor (extensor carpi radialis) muscle that bends the wrist back. It is hypothesized that training the wrist extensor muscle response to transcranial magnetic stimulation will increase the strength of the brain-to-muscle pathway, which will improve the ability to move the arm. It is hoped that the results of this training study will help in developing therapy strategies for individuals, promoting better understanding of clinical assessments, and understanding treatments that aim to improve function recovery in people with spinal cord injury (SCI). This study requires 30 visits, and each visit will last approximately 1.5 hours.

You may qualify if…
- ✓ 1. a history of injury to spinal cord at or above C6
- ✓ 2. neurologically stable (\>6 mo post SCI)
- ✓ 3. medical clearance to participate
- ✓ 4. weak wrist extension at least unilaterally
- ✓ 5. expectation that current medication will be maintained without change for at least 3 months. Stable use of anti-spasticity medication (e.g., baclofen, diazepam, tizanidine) is accepted. In participants with bilateral wrist extension weakness, the more severely impaired arm is studied.
You may not qualify if…
- ✕ 1. motoneuron injury
- ✕ 2. medically unstable condition
- ✕ 3. cognitive impairment
- ✕ 4. a history of epileptic seizures
- ✕ 5. metal implants in the cranium
- ✕ 6. implanted biomedical device in or above the chest (e.g., a cardiac pacemaker, cochlear implant)
- ✕ 7. no measurable MEP elicited in the ECR
- ✕ 8. unable to produce any voluntary ECR EMG activity
