Interventions
DEVICE
kTMP
A new non-invasive brain stimulation tool
DEVICE
Sham kTMP
A new non-invasive brain stimulation tool with sham setting selected
Primary outcome measures
Range of Joint Motion (ROM)
Time frame: 6 weeks
defined as the standard deviation of the joint angle time series for a given trial. The median ROM will be calculated for eleven degrees of freedom and then averaged. If there are joints which appear to be compensatory, they will be removed from the analysis
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Adults aged 18-80 years who have a history of an ischemic or hemorrhagic stroke ≥ 12 m prior to enrollment.
- Fugl-Meyer Assessment: Upper Extremity (FMA UE) score 20-50.
- Ability to communicate, understand, and give appropriate consent. Participants can follow two-step commands.
- Motor evoked potentials in a hand muscle when stimulating ipsilesional cortex with suprathreshold single-pulse TMS (MEP positive).
Exclusion criteria
- Participants with moderate or severe cognitive impairment (MoCA \< 18).
- Participants with sensory deficits FMA-S \< 6/12 (with proprioception \< 4/8).
- Participants with severe apraxia (TULIA \< 5).
- Language impairment or behavioral disorder that interferes with their ability to adhere to the protocol or to provide informed consent.
- Individuals who have a serious uncontrolled medical condition, including but not limited to severe cardiovascular and cardiopulmonary disease.
- Pregnancy or plans to become pregnant during the study period.
- Botulinum toxin injections of the affected upper extremity within 3 months prior to onset of study.
- Severe spasticity of the affected upper limb (Modified Ashworth ≥ 4).
- Absolute contraindications related to non-invasive brain stimulation, including: 9a) History of seizures in the last 12 months while taking anti-epilepsy medication 9b) Presence of any metal implants in the head (excluding the mouth), such as cortical stimulators and DBS, clips, coils, shunts, stents or skull plates, cochlear implants 9c) Permanent eye liner or head tattoos 9d) Implanted electronics such as pacemakers, defibrillators, intrathecal baclofen pumps or vagus nerve stimulator 9e) History of experiencing a serious adverse event during a previous transcranial magnetic stimulation (TMS) session

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
