Combining visual and proprioceptive feedback during motor imagery after hemiparetic stroke
Study of the Integration and Interactions Between Visual and Proprioceptive Feedbacks in Hemiplegic Patients
This test will see if using a computerized mirror and tendon vibration during motor imagery changes brain activity in adults with hemiparetic stroke.

What this trial studies
Adults with hemiplegic stroke will perform motor imagery tasks while receiving different feedback types (visual via an IVS3 computerized mirror, proprioceptive via Vibramoov tendon vibration, and combined feedback). Cortical activity will be recorded with EEG during each feedback condition to characterize neural responses. EEG patterns will be correlated with each participant's lesion location to identify how affected brain areas integrate visual and proprioceptive inputs. The project aims to map underlying mechanisms that could guide selection of feedback modalities in rehabilitation.
Who should consider this trial
Good fit: Adults aged 18–80 with a first ischemic or hemorrhagic hemiparetic stroke who can give informed consent and follow instructions, and who do not have severe cognitive impairment, aphasia, or neglect.
Not a fit: Patients with severe cognitive deficits, severe aphasia, severe neglect, or those unable to attend in-person EEG sessions are unlikely to benefit from or be eligible for this protocol.
Why it matters
Potential benefit: If successful, this could help tailor rehabilitation so clinicians choose visual or proprioceptive feedback that best matches a patient’s lesion, potentially improving motor recovery.
How similar studies have performed: Mirror therapy, tendon vibration, and motor imagery have individually shown benefits in prior stroke rehabilitation work, but combining these feedbacks and linking EEG responses to lesion location is relatively novel and less-tested.
