NCT02351921

Brief Summary

This study will investigate how repetitive transcranial magnetic stimulation delivered as a protocol called 'continuous theta-burst stimulation (cTBS)' alters motor output and force control to a muscle in the forearm and touch perception in individuals with chronic, incomplete spinal cord injury. CTBS is a non-invasive technique that involved repetitive delivery of transcranial magnetic stimulation at a frequency of 30 Hz over the arm representation in the primary motor or sensory cortex. The purpose of this study is to determine whether cTBS is an effective intervention to increase motor output to a muscle and increase force control of that muscle and also improve the sense of touch.

Outcome Measures

Primary Outcomes (1)

  • Measuring changes in motor evoked potential

    The motor evoked potential is the response obtained in the forearm muscle that follows single pulse TMS. The amplitude of this measure is an indicator of the corticospinal excitability. This measure will be obtained at baseline and 20 minutes following the intervention.

    Immediatately before intervention, and at 20 minutes following intervention

Secondary Outcomes (1)

  • Measuring changes in muscle force production

    Immediatately before intervention, and at 25 minutes following intervention

Study Arms (3)

iTBS to primary motor cortex

EXPERIMENTAL

Intermittent TBS will be delivered using the 30 Hz, 600 pulse protocol targeting the primary motor cortex of the left hemisphere. The iTBS TMS coil will be placed over the motor hotspot for the representation of the flexor carpi radialis muscle.

Device: Transcranial magnetic stimulation

iTBS to primary somatosensory cortex

EXPERIMENTAL

Intermittent TBS will be delivered using the 30 Hz, 600 pulse protocol targeting the primary motor cortex of the left hemisphere. The iTBS TMS coil will be placed over the primary somatosensory cortex located 2cm posterior to the motor hotspot for the representation of the flexor carpi radialis muscle.

Device: Transcranial magnetic stimulation

Sham iTBS to primary motor cortex

SHAM COMPARATOR

Sham iTBS will be delivered using the 30 Hz, 600 pulse protocol targeting the primary motor cortex of the left hemisphere. The iTBS sham coil will be placed over the motor hotspot for the representation of the flexor carpi radialis muscle.

Device: Transcranial magnetic stimulation

Interventions

Intermittent theta-burst stimulation is a form of repetitive Transcranial magnetic stimulation. ITBS is a non-invasive, non-painful procedure being used worldwide to study brain function and promote short-term changes (\~1 hour) in neural activity in the brain. The delivery of cTBS requires \~ 40 seconds in total.
