Summary

Mirror therapy (MT) has been demonstrated, in terms of neuroplasticity, to improve sensorimotor function of paretic upper extremity (UE) in chronic stroke patients. Central and peripheral electrical stimulation techniques such as ranscranial direct current stimulation (tDCS) and functional electrical stimulation (FES) can individually enhance effects of MT, combining both of them with MT can be a potentially valuable approach to maximize neural and functional recovery post stroke. To our knowledge, no studies combined central and peripheral neural network reorganization technique with motor behavioral learning approach to investigate its possible benefit after stroke. This project will be the first to design a "dual neurotechnology-aided MT (DNA-MT)", which combines tDCS and FES with contemporary neurorehabilitation approaches (i.e., MT) to stimulate both central and peripheral nervous systems to maximize neural and functional recovery post stroke. Investigators will determine the efficacy and neurophysiological and motor mechanisms related to this novel DNA-MT approach and identify potential responders to this novel intervention.

Eligibility

Yes No Not Sure

Inclusion Criteria

sustained a unilateral stroke with onset 3 months (Figlewski et al., 2017)
UE Fugl-Meyer assessment (UE-FMA) score between 18 and 56 indicating mild to moderate mild motor severity (Menezes et al., 2018; Woodbury, Velozo, Richards, & Duncan, 2013)

having unstable cardiovascular status such as uncontrolled hypertension or New York Heart Association (NYHA) Class III/IV heart failure
having contradictions to tDCS including a history of epilepsy, migraine headache, uncontrolled medical status, being pregnant, having a pacemaker, or metal implanted in their head or body (not including dental fillings or hardware)(Meeker et al., 2019; Rossi, Hallett, Rossini, Pascual-Leone, & Group, 2009)
having a history of drug or alcohol abuse, dermatosis preventing tDCS from being applied, brain tumor, brain injury, arteriovenous malformation, other brain diseases (such as intracranial hypertension or cerebral edema), or are not suitable for using tDCS by the physician's assessment; and (8) having existence of skin rash, allergy or wounds at the locations where stimulation electrodes would be placed
