Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
We will perform a special study to test both treatments simultaneously. Children 7-18 years with stroke-induced CP will be recruited into the study from across Alberta. Each child will randomly receive either TMS, CIMT, both, or neither each day for two weeks while attending our new HemiKids Power Camp for motor learning. Improvements will be measured by trained therapists over 1 year. TMS will also measure brain plasticity, both initially and following treatment. Our lead investigator is an expert in both newborn stroke and TMS and has assembled an experienced team of accomplished collaborators to ensure the completion of this important work. This will be the largest study of children with CP examined in this manner. This will be the first clinical trial of non-invasive brain stimulation (TMS) in CP, the largest trial of CIMT (and the first exclusive to newborn stroke), and the first study allowing the direct comparison of two different therapies. In establishing the first dedicated pediatric TMS laboratory in Canada, we will be the first to measure plasticity changes in newborn stroke, advancing new treatments of this previously untreatable and disabling disease.
Patient recruitment is currently underway at Alberta Children's Hospital. Application is currently underway to expand recruitment to Northern Alberta through the Glenrose Rehabilitation Hospital and Stollery Children's Hospital, to enable patients from Northern Alberta greater opportunity to participate as subjects in this study.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Transcranial magnetic stimulation (TMS) offers non-invasive measurement of the neurophysiological brain properties underlying neuroplasticity. Repetitive TMS (rTMS) may modulate such systems with therapeutic effect. the investigators recently demonstrated the ability of rTMS to improve motor function in children with chronic stroke. Advances in perinatal brain injury and neurodevelopment are, for the first time, affording novel windows of opportunity for interventions to direct plastic organization toward better outcomes. Via the Alberta Perinatal Stroke Project (APSP), the investigators propose a clinical trial of two interventions to improve function in HCP while measuring the fundamental neurophysiological properties at play.
Aim 1. Determine if rTMS and CIMT can improve motor function in HCP. Hypothesis: Two weeks of daily rTMS improves motor function at 30 days.
Aim 2. Define the neurophysiology of motor organization in stroke-induced HCP at baseline and following rTMS and CIMT.
Hypothesis: rTMS and CIMT reduce excitability of the non-lesioned motor cortex.
Population-based studies through the Alberta Perinatal Stroke Project (APSP) are establishing the largest perinatal stroke cohort to date. The investigators will complete a factorial 2 x 2 randomized clinical trial to determine the ability of daily rTMS and CIMT to improve motor function in children with HCP. Families will attend a child-centered, custom-designed intensive motor learning rehabilitation program (KidsCan Power Camp) for 2 weeks. Outcomes include validated measures of motor function and CP quality of life. The investigators will simultaneously measure the neurophysiology of plastic organization using TMS including cortical excitability, interhemispheric inhibition, and short interval intracortical inhibition. Baseline measures will define organization patterns while post-interventional measurement will evaluate the neurophysiological effects of rTMS and CIMT. Four groups of 16 children each (n=64) will be studied over 24 months with interim safety analysis after 10 and 32 patients.
Successful completion is assured by principle investigator experience in perinatal stroke and TMS and the collaborative support of world leaders in pediatric and adult stroke, TMS, basic neuroscience, and physiatry/rehabilitation. Understanding perinatal stroke plasticity and discovering methods to modulate it toward better outcomes carries a large impact, greatest for children with CP and their families.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
rTMS and CIMT
This group will receive both rTMS and CIMT.
Repetitive Transcranial Magnetic Stimulation (rTMS)
TMS can affect discrete functional ares of motor cortex offering non-invasive, painless mapping and modulation of motor systems. Inhibitory rTMS (1Hz)has been shown to safely lower motor cortex excitability in normal patients as well as adult and pediatric stroke patients. Dose is 20 minutes per day (1200 stimulations) x 10 days administered over the non-lesioned M1.
Constraint-induced movement therapy (CIMT)
CIMT uses gentle restraint of the fully functional upper extremity to promote functional gains in the affected upper extremity. CIMT is well established to be safe and is likely effective in children with hemiplegic cerebral palsy, many of whom have perinatal stroke as studied here. A custom-fitted, bivalved cast is applied and worn for \>90% of waking hours for the 2 weeks of active treatment according to protocol with daily assessments for comfort.
rTMS and no CIMT
This group will receive rTMS only.
