Clinical Trial Summary

A repetitive, non-invasive brain stimulation technique referred to as theta burst stimulation can modulate corticomotor excitability and therefore has great rehabilitative potential for individuals with neurologic deficits, including individuals with spinal cord injury (SCI). In particular, intermittent theta burst stimulation (iTBS) can increase corticomotor excitability and may be a useful adjunct to physical rehabilitation to promote motor re-education after upper limb reconstruction in individuals with tetraplegia. Upper limb reconstruction involves surgical transfer of a non-paralyzed tendon or nerve with a redundant or less important function to perform a more critical function. Upper limb reconstruction is intended to help individuals achieve their goals related to activities of daily living and independence in the community. Outcomes after reconstruction are variable and depend largely on the efficacy of motor re-education of the transferred muscle to perform a new function. The long-term goal of our research is to determine whether iTBS combined with physical rehabilitation can improve motor re-education after reconstruction. As a first step, the purpose of this proposal is to determine the effect of iTBS on corticomotor excitability of proximal muscles in nonimpaired individuals and two groups of individuals with tetraplegia: individuals with and without upper limb reconstruction.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in corticomotor excitability	Corticomotor excitability will be measured via motor evoked potential amplitudes in response to transcranial magnetic stimulation	Each subject will participate in five sessions, each session separated by 3 days. After each session, changes in corticomotor excitability will be measured. Changes in excitability will be reported through study completion, an average of one month.
