About this study

Official title: Premotor Cortex: A New Target for Stroke Motor Rehabilitation Using Transcranial Magnetic Stimulation

The goal of the study is to determine the effect of repetitive transcranial magnetic stimulation (rTMS) over the premotor cortex on training-related improvements in motor performance and associated neural plasticity.

Read the detailed description

Occlusion of the middle cerebral artery is the most common cause of stroke. Because the middle cerebral artery supplies blood to the motor cortices, middle cerebral artery stroke often impacts the integrity of the motor cortex and its associated corticospinal projections. Consequently, the majority of the 6.8 million people who have suffered a stroke in the United States experience hemiparesis as a result of the infarct. Although stroke survivors are encouraged to participate in rehabilitation programs, less than half of all individuals post-stroke regain complete motor function. Because motor deficits, especially of the upper extremities, can dampen the quality of life, there is an urgent need to improve current rehabilitation programs to allow more stroke survivors to achieve higher functional gains.

Motor training is an important part of recovery after stroke. During motor training, stroke patients practice performing a movement and become better at performing the trained movement over time. Repetitive transcranial magnetic stimulation (rTMS), which uses magnetism to excite neurons near the surface of the brain, may further improve performance. Healthy adults made larger training-related improvements in their motor performance when they received rTMS over the primary motor cortex during motor training. There is evidence that the premotor cortex may be a more effective target than the primary motor cortex for rTMS for some stroke survivors. In the current study, the investigator will determine the effect of rTMS over the premotor cortex on training-related improvements in motor performance in healthy adults.

In this study the researchers will evaluate the effect of premotor cortex (PMC) rTMS on motor learning with a double-blind randomized study consisting of five experiments separated by at least 72 hours. During each experiment, participants complete motor training while receiving one of five rTMS protocols. All participants will receive each rTMS protocol once. The order of the rTMS protocols will be randomized and counterbalanced prior to recruitment. The researchers will evaluate the effect of each rTMS protocol on training-related motor learning by collecting kinematic and neurophysiological measurements before (pre-training), immediately post-training, and 60 minutes post-training.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • rTMS Over Contralateral Hemisphere of Premotor CortexDevice

    Also called MagStim Super Rapid 2 Transcranial Magnetic Stimulator

    This intervention uses rTMS located over the premotor cortex of the contralateral hemisphere (opposite side of the body) to the training wrist. For this intervention the rTMS occurs at a frequency of 0.1 Hz, 50 milliseconds (ms) before the onset of movement-related electromyography (EMG). The MagStim Super Rapid 2 Transcranial Magnetic Stimulator is used.

  • rTMS Over Ipsilateral Hemisphere of Premotor CortexDevice

    Also called MagStim Super Rapid 2 Transcranial Magnetic Stimulator

    This intervention uses rTMS located over the premotor cortex of the ipsilateral hemisphere (the same side of the body) to the training wrist. For this intervention the rTMS occurs at a frequency of 0.1 Hz, 50 milliseconds (ms) before the onset of movement-related EMG. The MagStim Super Rapid 2 Transcranial Magnetic Stimulator is used.

  • Control 1: rTMS Timed 400 ms After Movement-related EMGDevice

    Also called MagStim Super Rapid 2 Transcranial Magnetic Stimulator

    Control condition 1 uses rTMS over the premotor cortex of the contralateral hemisphere to the training wrist, with a frequency of 0.1 Hz. The rTMS occurs 400 milliseconds (ms) after the onset of movement-related EMG and uses the MagStim Super Rapid 2 Transcranial Magnetic Stimulator.

  • Control 2: rTMS Over the Somatosensory CortexDevice

    Also called MagStim Super Rapid 2 Transcranial Magnetic Stimulator

    This intervention uses rTMS located over the somatosensory cortex of the contralateral hemisphere to the training wrist. For this intervention the rTMS occurs at a frequency of 0.1 Hz, 50 milliseconds (ms) before the onset of movement-related EMG. The MagStim Super Rapid 2 Transcranial Magnetic Stimulator is used.

  • Control 3: Sham rTMSDevice

    Also called MagStim Super Rapid 2 Transcranial Magnetic Stimulator with Sham Coil

    Control condition 3 uses rTMS located over the premotor cortex of the contralateral hemisphere to the training wrist, at a frequency of 0.1 Hz, 50 milliseconds (ms) before the onset of movement-related EMG. The MagStim Super Rapid 2 Transcranial Magnetic Stimulator with the sham coil is used.

  • Motor TrainingOther

    During motor training, participants will quickly extend their hand at a pace of one extension every 5 seconds (0.2Hz) in response to an auditory cue.

Study groupRoleWhat they receive
Repetitive TMS During Motor TrainingExperimentalHealthy, right-handed participants complete five testing sessions. During each testing session, participants complete motor training while receiving one of five repetitive transcranial magnetic stimulation (rTMS) protocols. Participants receive a different rTMS protocol at each testing session so that they receive all rTMS protocols by the end of the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Primary Motor Cortex (M1) Excitability Derived From Stimulus Response Curve (SRC)

    Functional organization of ipsilateral M1 is assessed by changes in area under the curve of stimulus response curves over the hotspots of an agonist (extensor carpi ulnaris (ECU)) muscle of the training movement. The area under the curve (AUC) was calculated by summing the mean motor evoked potential (MEP) amplitudes per intensity and subject evoked by TMS at intensities 25 -80% maximum stimulator output (MSO), in increments of 5% MSO. The area under the stimulus response curve is normalized to the pre-training measurement.

    Measured: Baseline/Pre-training, Immediately Post-training, 60 Minutes Post-training during each of 5 study visits (up to 217 days)

Secondary outcomes (2)
  1. Change in Mean Reaction Time

    Participants are asked to perform 7 auditory-cued ballistic wrist extensions before and after motor training. Electromyographic (EMG) activity recorded during the ballistic wrist extensions is used to measure reaction time. Reaction time is the length of time between the auditory cue and the onset of the movement-related EMG burst of the extensor carpi ulnaris (ECU) muscle. The change in reaction time from baseline is calculated as the post-training score minus the baseline score.

    Measured: Baseline/Pre-training, Immediately Post-training, 60 Minutes Post-training during each of 5 study visits (up to 217 days)

  2. Change in Mean Peak Velocity

    Peak velocity of wrist movement from 6 auditory-paced ballistic wrist extension was collected using a gyrometer. Peak velocity is an assessment of hand motor kinematics. Velocity measures speed in a particular direction of motion.

    Measured: Baseline/Pre-training, Immediately Post-training, 60 Minutes Post-training during each of 5 study visits (up to 217 days)
