Non-invasive BCI-controlled Assistive Devices
Motor Disorders, Healthy, Spinal Cord Injuries
About this trial
This is an interventional treatment trial for Motor Disorders focused on measuring motor deficits, able-bodied, healthy, unilateral and bilateral stroke, spinal cord injury, motor neuron diseases, muscular diseases (i.e. myopathy), traumatic or neurological pain, movement disorders
Eligibility Criteria
Inclusion Criteria:
- Able-bodied participants:
- good general health
- normal or corrected vision
- no history of neurological/psychiatric disease
- ability to read and understand English (Research Personnel do not speak Spanish)
- Subjects with motor disabilities
- motor deficits due to: unilateral and bilateral stroke / spinal cord injury / motor neuron diseases (i.e. amyotrophic lateral sclerosis, spino-cerebellar ataxia, multiple sclerosis) / muscular diseases (i.e. myopathy) / traumatic or neurological pain / movement disorders (i.e. cerebral palsy) / orthopedic / traumatic brain injury / brain tumors
- normal or corrected vision
- ability to read and understand English (Research Personnel do not speak Spanish)
- ability to provide informed consent
Exclusion Criteria:
- Subjects with motor disabilities
- short attentional spans or cognitive deficits that prevent to remain concentrated during the whole experimental session
- heavy medication affecting the central nervous system (including vigilance)
- concomitant serious illness (e.g., metabolic disorders)
- All participants
- factors hindering EEG/EMG acquisition and FES/tdCS/tACS delivery (e.g., skin infection, wounds, dermatitis, metal implants under electrodes)
- criteria identified in safety guidelines for MRI and TMS, in particular metallic implants
Sites / Locations
- The University of Texas at AustinRecruiting

Active Comparator
NMES-BCI
Visual-BCI
Sensory-threshold electrical stimulation is delivered to the flexors/extensors of the forearm contingent to the voluntary activation of the motor cortex by motor imagery of hand flexion/extension as detected by a closed-loop BCI.
Bar-based visual feedback is provided on a screen contingent to the voluntary activation of the motor cortex by motor imagery of hand flexion/extension as detected by a closed-loop BCI.
