  • An MRI visit
  • Two testing visits in which motor function of the upper limb and neurophysiology will be measured
  • 12 intervention visits during which patients will receive upper limb training in conjunction with non-invasive brain stimulation
  • Repeat testing of motor function of the upper limb and neurophysiology
  • Repeat MRI testing
  • A follow-up visit completed 3 months after the completion of interventions
Read the detailed description

In a pilot, randomized clinical trial, 24 stroke patients with moderate/severe impairments will receive non-invasive brain stimulation (repetitive Transcranial Magnetic Stimulation or rTMS) to one of two targets in the brain in conjunction with upper limb training for 2 days a week for 6 weeks. The primary outcome will be upper limb motor impairment, and secondary outcomes will be tests of functional abilities, proximal motor control, and patient-reported disability. Associated neural mechanisms will also be studied using neurophysiological and functional connectivity MRI techniques. Damage to ipsilesional corticospinal pathways will be indexed with diffusion tensor imaging (DTI).

What participants receive

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

  • New Repetitive Magnetic Stimulation (rTMS) ApproachDevice

    Also called Contralesional dorsal premotor cortex (cPMD) rTMS + Training

    Participants in this arm will receive rTMS-based facilitation of the contralesional dorsal premotor cortex (cPMd) located in the non-stroke hemisphere before start of each session. High-frequency rTMS (5-Hz) will be delivered using 42 10-sec trains of 50 pulses each (total 2100 pulses) for a period of 24 minutes. Immediately after the completion of rTMS, participants will undergo upper limb training for a total of one hour. Participants will receive these interventions 2 days a week for 6 weeks, i.e., for a total of 12 sessions.

  • Conventional Repetitive Magnetic Stimulation (rTMS) ApproachDevice

    Also called Ipsilesional Primary Motor Cortex (iM1) rTMS + Training

    Participants in this arm will receive rTMS-based facilitation of the ipsilesional primary motor cortex (iM1) before the start of each session. iM1 will be stimulated with high-frequency rTMS (5-Hz) using 42 10-sec trains of 50 pulses each (total 2100 pulses) for a period of 24 minutes. Immediately after the completion of rTMS, participants will undergo upper limb training for a total of one hour. Participants will receive these interventions 2 days a week for 6 weeks, i.e., for a total of 12 sessions.

What is being measured

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

  1. Change in Upper Extremity Fugyl-Meyer Score (UEFM)

    Change between Baseline and Post-Test (average 6 weeks) is reported for the UEFM. Impairment will be measured using UEFM, one of the most widely used assessments in stroke. UEFM will serve as our primary outcome because it is sensitive to discerning the effects of rTMS/rehabilitation, and has excellent reliability (ICC= 0.97), consistency (Cronbach's α= 0.84) and validity. UEFM has a score ranging from 0-66 (0 meaning there is no movement of the paretic arm, and 66 meaning there is no functional limitation of the paretic arm.)

    Measured: Change between Baseline and Post-Test (average 6 weeks)

  2. Change in Inter-hemispheric Inhibition (IHI)

    Inter-hemispheric connectivity (IHI) will be collected with transcranial magnetic stimulation (TMS) and is assessed using ipsilateral silent period (ISP) method. TMS is delivered to the contralesional motor hotspot at supra-maximal intensity (100% maximum stimulator output) while participants maintain sub-maximal contraction (50% maximum volitional contraction) of the ipsilateral paretic extensor digitorum communis muscle for 40 trials. Ipsilateral TMS produces transient suppression of on-going EMG activity, called ISP. ISP is analyzed using an algorithm that compares psotstimulus average rectified EMG to mean consecutive difference (MCD) of background EMG. A threshold of MCD x1.77 below mean background EMG is used to define ISP onset and offset. ISP duration is then calculated as a difference between onset and offset of the ISP.

    Measured: Change between Baseline and Post-Test (average 6 weeks)

Secondary outcomes (9)

  1. Change in Wolf Motor Function Test (WMFT) Functional Ability

    Change in Functional Ability (FA) from Baseline to Post-Test (average 6 weeks) is reported for the Wolf Motor Function Test. Functional ability (FA) to use the paretic upper limb in a variety of tasks will be assessed using WMFT. FA is scored on a scale from 0-5 with 0 not attempting the task at all and 5 being completely normal movement compared to non paretic limb. 15 items of WMFT are given a FA for the Paretic limb and then the score is averaged to give an overall FA for each participant.

    Measured: Change between Baseline and Post-Test (average 6 weeks)

  2. Change in Wolf Motor Function Test (WMFT) Rate Paretic Limb

    Change in Rate of the Paretic limb from Baseline to Post-Test (average 6 weeks) is reported for the Wolf Motor Function Test. Time to complete each task will be noted and converted to rate (60/Performance Time (sec)), optimized for measurement in moderately/severely-impaired patients. The rate will be calculated for the Paretic limb [WMFT Rate (P)]. The higher the rate the quicker they were able to complete the task.

    Measured: Change between Baseline and Post-Test (average 6 weeks)

  3. Change in Wolf Motor Function Test (WMFT) Rate Non-paretic Limb

    Change in Rate of the Non-paretic limb from Baseline to Post-Test (average 6 weeks) is reported for the Wolf Motor Function Test. Time to complete each task will be noted and converted to rate (60/Performance Time (sec)), optimized for measurement in moderately/severely-impaired patients. The rate will be calculated for the Non-paretic limb [WMFT Rate (NP)]. The higher the rate the quicker they were able to complete the task.

    Measured: Change between Baseline and Post-Test (average 6 weeks)

  4. Change in Wolf Motor Function Test (WMFT) Rate Paretic Limb Normalized to the Non-paretic Limb

    Change in the normalized Rate of the Paretic limb to the Non-paretic limb from Baseline to Post-Test (average 6 weeks) is reported for the Wolf Motor Function Test. Time to complete each task will be noted and converted to rate (60/Performance Time (sec)), optimized for measurement in moderately/severely-impaired patients. The rate will be calculated for the Paretic limb normalized to the Non-paretic limb [WMFT Rate (P/NP)]. The higher the rate the quicker they were able to complete the task.

    Measured: Change between Baseline and Post-Test (average 6 weeks)

  5. Change in Stroke Impact Scale (SIS-16)

    Change in total score between Baseline and Post-Test (average 6 weeks) is reported for the Stoke Impact Scale (SIS-16) for each group. Patient's perceived disability related to physical function will be indexed using the Stroke Impact Scale (SIS-16) which a subjective questionnaire asked to the subject pertaining of 16 questions. Each question is rated on scale from 1 to 5 and then the scores are totaled. Total scores can range from 16-80 (16 means that none of the functional tasks asked can be performed, a score of 80 means the subject has no issues at all performing any of the tasks asked).

    Measured: Change between Baseline and Post-Test (average 6 weeks)

  6. Change Resting State Functional Magnetic Resonance Imaging(rsfMRI)

    Functional connectivity will complement IHI measurement as a secondary outcome because while IHI records neurophysiologic interactions between a contralesional and a weak ipsilesional region, functional connectivity defines "global" interactions across multiple regions.

    Measured: Change between Baseline and Post-Test (average 6 weeks)

  7. Change in Ipsilateral MEPs (Motor Evoked Potentials)

    Output of uncrossed pathways will be studied as ipsilateral MEPs elicited in the paretic-muscle with TMS.

    Measured: Change between Baseline and Post-Test (average 6 weeks)

  8. Diffusion Tensor Imaging (DTI)

    Diffusion Tensor Imaging (DTI) enables the investigation of structural integrity and orientation of pathways in vivo through the estimation of magnitude and directionality of water diffusion. DTI metrics can help quantitate damage even when patients show no response to Transcranial Magnetic Stimulation (TMS) due to extensive damage (MEP-). Ipsilesional and contralesional corticospinal tracts will be reconstructed using probabilistic tractography. Fractional Anisotropy (FA), a unit-less measure of white matter integrity, will be calculated.

    Measured: Baseline

  9. Change in SULCS

    Change in total score between Baseline and Post-Test (average 6 weeks) is reported for the Stroke Upper Limb Capacity Scale (SULCS). SULCS is a stroke-specific assessment instrument that evaluates functional capacity of the upper limb based on the execution of 10 tasks. Score ranges from 0-10 where 0 is the lowest level of function in which the participant cannot perform any of the tasks as instructed and 10 is the highest level of function in which all 10 tasks are completed as instructed.

    Measured: Change between Baseline and Post-Test (average 6 weeks)
