Study Overview
Brief Summary
The goal of this clinical research study is to learn about using Navigated Transcranial Magnetic Stimulation (nTMS) in patients having surgery to remove a brain tumor in areas of the brain that control movement (motor function) and/or speech.
nTMS is a system designed to map the brain's function relating to movement and speech.
Detailed Description
If you agree to take part in this study, you will be assessed by the nTMS system before surgery and then at the same time as your routine follow-up visits, about 1, 3, 6, and 12 months after surgery.
At each visit, the following will occur:
- For motor mapping, pads to monitor your movements will be placed on your face, arms and legs. A coil that is used to deliver stimulation will be placed on your head. During stimulation, you will be asked to move certain muscles and will be monitored for motor responses over the course of 20 to 30 minutes. You may feel a mild tingling sensation in your arms and/or legs during stimulation.
- For speech mapping, you will be shown 95 black-and-white drawings of common objects and asked to name them. During stimulation, you will be asked to name the objects again and will be monitored for changes in speech or delays. You may feel a mild tingling sensation and contraction of the muscles in the face during stimulation. This should take about 1½-2 hours to complete.
You will sign a separate consent form that describes the surgery you will have and its risks in more detail. Information collected during surgery will be compared to nTMS information collected before and after surgery.
Your nTMS data, health information from your routine physical exams, and data about your motor and speech function collected during surgery will be analyzed by researchers. Basic information (such as your age, sex, and race) will also be collected from your medical record.

Arms & Interventions
Navigated Transcranial Magnetic Stimulation (nTMS)
Participant assessed by nTMS system before surgery, then again at 1, 3, 6, and 12 months following surgery. Motor mapping and speech mapping performed at these visits. This should take about 1½-2 hours to complete.
Intervention: Motor Mapping (Procedure)
Navigated Transcranial Magnetic Stimulation (nTMS)
Participant assessed by nTMS system before surgery, then again at 1, 3, 6, and 12 months following surgery. Motor mapping and speech mapping performed at these visits. This should take about 1½-2 hours to complete.
Intervention: Speech Mapping (Procedure)
Outcomes
Primary Outcomes
Pre and Post-Operative Functional Outcomes Using Navigated Transcranial Magnetic Stimulation (nTMS)
Time Frame: 12 months
Data obtained using nTMS correlated with data collected intraoperatively during direct electrical stimulation (DES). nTMS stimulation also correlated with neurological status and functional recovery after surgery. The Chi-square or Fisher's exact tests used to explore associations between categorical variables. T-tests, Wilcoxon rank sum tests, or regression models used for continuous variables.
Secondary Outcomes
No secondary outcomes reported
