Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to develop a clinically feasible, low-cost, nonsurgical neurorobotic system for restoring function to motor-impaired stroke survivors that can be used at the clinic or at home. Moreover, another goal is to understand how physical rehabilitation assisted by robotic device combined with electroencephalograph (EEG) can benefit adults who have had stroke to improve functions of their weaker arm.

The proposed smart co-robot training system (NeuroExo) is based on a physical upper-limb robotic exoskeleton commanded by a non-invasive brain machine interface (BMI) based on scalp EEG to actively include the participant in the control loop .

The study will demonstrate that the Neuroexo smart co-robot arm training system is feasible and effective in improving arm motor functions in the stroke population for their use at home.The NeuroExo study holds the promise to be cost-effective patient-centered neurorehabilitation system for improving arm functions after stroke.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study has two phases: The first phase will consist of baseline recordings for system calibration and training sessions to be conducted in a clinical setting. The second phase will consist of NeuroExo BMI-exo neurotherapy to be conducted at the participant's home. Throughout the study and after completion of the study, movement and brain activity will be analyzed to assess function of the affected upper extremity and changes in brain activity associated with the neurotherapy.

Study Groups

NeuroExo

NeuroExo is a device which includes a robotic exoskeleton that you were in your affected arm to assist you with arm movements, a headset that you wear on your head to measure your brain activity and detect your intention to move, and a graphical user interface that allows you to initiate and stop neurotherapy, and track your motor performance.

Group Type EXPERIMENTAL

NeuroExo co-robot neurorehabilitation system

Intervention Type DEVICE

In this longitudinal study, adult subjects with hemiparesis due to chronic stroke will receive robotic-assisted upper-arm training through an EEG-based BMI control of robotic exoskeleton to study the changes in upper extremity motor function, cortical plasticity (using the EEG). After one screening visit, two baseline visits for EEG signal screens, six onsite training sessions will be provided with the NeuroExo system, followed by 60 home therapy sessions (2 sessions per day, 5 days per week for 6 weeks). If the participant have completed at least 50 sessions of neurotherapy at home, the participant will complete a set of measurements to assess function of the affected upper arm and brain activity within 3 days after the last session for post-assessment visit, and one-month post follow-up session. The total amount of time for this study is 16-20 weeks.
