Brief Summary

This study is a necessary and important step in the development of a new therapy for upper limb functional recovery in patients with severe motor impairment. It is the first clinical trial of non-invasive brain stimulation (repetitive transcranial magnetic stimulation or rTMS) delivered to excite the undamaged hemisphere (specifically the contralesional higher motor cortices or cHMC) in stroke. Therefore, this study will determine whether the positive results obtained in our short-term pilot study can be made to last longer and produce functional benefits in severe patients with the application of brain stimulation in combination with long-term rehabilitation therapy. Rehabilitation therapy administered is called contralaterally controlled functional electrical stimulation (CCFES). Determining whether combining rTMS facilitating the cHMC with CCFES produces synergistic gains in functional abilities in severe patients is necessary for acceptance by the clinical community and to move this technology toward commercialization and widespread dissemination. The proposed study will determine whether the combination of rTMS facilitating the cHMC with CCFES produces greater improvements in upper extremity function in severe participants who are ≥6 months from stroke onset than the combination of rTMS facilitating the damaged hemisphere (specifically the ipsilesional primary motor cortex, iM1) and CCFES or the combination of sham rTMS and CCFES. The secondary purposes are to define which patients benefit most from the treatments, which may inform future device and treatment development and clinical translation, and to explore what distinct effects the three treatments have on the brain. To accomplish these purposes, we are conducting a clinical trial that enrolls severe stroke patients.

Outcome Measures

Primary Outcomes (1)

  • Change in Upper Extremity Fugl-Meyer (UEFM)

    The UEFM is a reliable and valid measure of post-stroke upper limb motor impairment. The UEFM items take into account synergy patterns, isolated strength, coordination, and hypertonia. Volitional movement of the upper limb (shoulder, elbow, forearm, wrist, and hand) is examined in and out of synergies. Each item is graded on a 3-point ordinal scale (0, cannot perform; 1, perform partially; and 2, perform fully) and summed to provide a maximum score of 66. The UEFM is classified as a body structure/function impairment measure on the ICF domain.

    Change in UEFM will be assessed at at 6 weeks, 12 weeks (end of treatment), 24 weeks, and 36 weeks.

Other Outcomes (1)

  • Change in Neurophysiologic Assessments

    Change in neurophysiologic indices will be measured at 12 weeks (end of treatment) and at 36 weeks, on a separate day from functional motor outcomes assessment.

Study Arms (3)

CCFES + rTMS facilitating cHMC

ACTIVE COMPARATOR

This rTMS paradigm is the "New Approach". Facilitation of the intact hemisphere target (cHMC) will be achieved using 5Hz rTMS. After rTMS, the participant will participate in one hour of CCFES-mediated functional task practice. The therapist will instruct and guide the participants in practicing functional tasks with their paretic hand with the assistance of CCFES. Tasks will involve using the paretic hand to pick up, manipulate, and release objects commonly used in daily life. Early sessions will focus on simpler tasks, such as practicing opening the hand adequately to acquire an object.

CCFES + rTMS facilitating iM1

ACTIVE COMPARATOR

This rTMS paradigm is the "Conventional Approach".Facilitation of M1 will be achieved using 5Hz rTMS. After rTMS, the participant will participate in one hour of CCFES-mediated functional task practice. The therapist will instruct and guide the participants in practicing functional tasks with their paretic hand with the assistance of CCFES. Tasks will involve using the paretic hand to pick up, manipulate, and release objects commonly used in daily life. Early sessions will focus on simpler tasks, such as practicing opening the hand adequately to acquire an object.

Device: Contralaterally Controlled Functional Electrical StimulationDevice: Conventional rTMS approach

CCFES + Sham rTMS

SHAM COMPARATOR

This rTMS paradigm is the "Sham Approach". Immediately after sham rTMS, the participant will participate in one hour of CCFES-mediated functional task practice. The therapist will instruct and guide the participants in practicing functional tasks with their paretic hand with the assistance of CCFES. Tasks will involve using the paretic hand to pick up, manipulate, and release objects commonly used in daily life. Early sessions will focus on simpler tasks, such as practicing opening the hand adequately to acquire an object.

Interventions

Contralaterally Controlled Functional Electrical Stimulation (CCFES) uses electrical stimulation to open the weak hand. Sticky patches called electrodes are placed on the participant's affected arm to stimulate the hand muscles, and a special glove is worn on the participant's strong hand and controls the stimulator. When the participant opens the gloved hand, stimulation opens the weak hand; when they close the gloved hand, stimulation turns off and the weak hand relaxes. During the clinic visits, participants will use CCFES to assist hand opening during functional training. During participant home sessions, they will use CCFES to perform hand opening exercise.

Also known as: CCFES
CCFES + Sham rTMSCCFES + rTMS facilitating cHMCCCFES + rTMS facilitating iM1

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 + CCFES for a total of one hour. Participants will receive these interventions 2 days a week for 12 weeks.

Also known as: iM1 rTMS + CCFES and upper limb training
CCFES + rTMS facilitating iM1

In the sham rTMS group, ipsilesional motor hotspot will be targeted in half the patients and cHMC location will be targeted in the other half (based on random assignment). Immediately after the completion of rTMS, participants will undergo upper limb training + CCFES for a total of one hour. Participants will receive these interventions 2 days a week for 12 weeks.

Masking Details
Subjects will be told they will receive brain stimulation, but will be given no indication as to which target will be stimulated. Investigators analyzing functional outcome data, neurophysiology data and MRI data will receive coded data that conceals the identity of the subject. Therapists involved in training patients will not know which type of rTMS the participant receives.
Purpose
TREATMENT
Intervention Model
PARALLEL
Model Details: In a randomized-controlled, assessor-blinded clinical trial, an anticipated 72 patients will be assigned to receive 12 weeks of CCFES + cHMC facilitation, or CCFES + iM1 facilitation, or CCFES + sham rTMS. Assessments of upper limb motor function and neurophysiology will be completed at baseline, 6, 12, 24, and 36 weeks. This study will 1) determine whether cHMC facilitation augments the effects of CCFES to produce greater improvements in upper limb function in severe patients, 2) investigate the underlying neurophysiologic mechanisms contributing to restored paretic limb motor control, and 3) evaluate and identify patient factors that affect efficacy of CCFES + cHMC facilitation.
