EMG-Controlled Game to Retrain Upper Extremity Muscle Activation Patterns Following Stroke
(GAM)
What this study is about
The purpose of this study is to develop and test if upper limb task practice and muscle activity training improve upper limb function in stroke survivors. Participants will be asked to come to the laboratory 23 times (approximately 3 times a week) over 2.5 months to receive upper limb task practice, muscle activity training, and/or upper extremity functional assessments.

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
- 18+ years old
- Stroke more than 6 months ago
- Moderate unilateral upper limb impairment
- Cognitive ability to participate in the study procedure
- Ability to see the full computer screen
Exclusion criteria
- Concurrent upper limb rehabilitation
- Inability to voluntarily contract muscles of at least 2 upper limb muscle groups, prohibiting participation in training
- Change in spasticity medication or botulinum toxin injection in the upper limb within 3 months prior to or during enrollment
- Total sensory loss
- Comorbidity (e.g., orthopaedic or premorbid neurologic condition) that limit upper limb movement and/or participation in the intervention
- Language barrier or cognitive impairment that precludes providing consent
Where

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.
