Outcome Measures
Primary Outcomes (1)
Device Survey For Feasibility
Subjective feedback regarding feasibility of the device for training
Post-intervention (immediately following last session of intervention)
Other Outcomes (12)
Retention
Post-intervention (immediately following last session of intervention)
Adherence
Post-intervention (immediately following last session of intervention)
Upper extremity Fugl-Meyer Score
Baseline and post-intervention measurements will be taken on separate days, within a week of the first and last sessions of the intervention, respectively.
- +9 more other outcomes
Study Arms (1)
Robotic Intervention
EXPERIMENTALParticipants will receive upper extremity rehabilitation using SepaRRo and NeuRRoFES 2-5 times per week for 2-6 weeks
Interventions
Participants will perform functional movements (e.g., reach for targets) with their extremities. During movements, the devices will be used to assist or resist their motion. Participants may receive biofeedback of their movements to better engage them in training. Participants may receive assistance from the devices (including neuromuscular stimulation) and/or their less-impaired limb.
Eligibility Criteria
You may qualify if:
- Age 18 to 75 years;
- Ischemic or hemorrhagic stroke confirmed by CT, MRI, or clinical criteria;
- No major deficits of sensation or proprioception;
You may not qualify if:
- Bilateral stroke
- Unable to think clearly and remember (Mini-Mental State Exam score \< 22 and miniMOCA \< 8);
- Uncontrolled Diabetes or Hypertension;
- Severe limitations of joint range of motion that will lead to inability of testing
- Severe spasticity and joint contractures that will lead to inability of testing
- Complete paresis with no possible movements
- Severe aphasia
- Any other medical condition that will significantly impact the study results
- Unable to obtain reliable motor evoked potentials
- Are pregnant or are actively trying to conceive
- Have a recent history of repeated fainting spells or syncope.
- Have a recent history of seizure (epilepsy) while on anti-seizure medication
- Have a recent history of skull fracture/head injury
- Have metal implants in the skull
- Have cardiac pacemakers
