PostureCheck for Robot-assisted Upper-limb Therapy after Stroke

This study is testing two ways to deliver robot-assisted upper-limb therapy for people who have had a stroke. One group will receive individual (one-on-one) therapy using the BURT system. The other group will receive group therapy (up to three people) using the BURT system plus PostureCheck, a camera-based system that tracks exercise quality and provides feedback. The goal is to see if group therapy with PostureCheck can be as effective as individual therapy. You may be able to join if you are 18-80 years old, had a stroke 6 months to 6 years ago, and have moderate to severe arm weakness. The study will measure changes in arm function using a score called the Fugl-Meyer Assessment - Upper Extremity (FMA-UE) after 7-8 weeks. The current recruitment status is unclear.

Study design
This is a single-blinded randomized clinical trial with a planned enrollment of 42 participants. Participants will be randomly assigned to either individual or group therapy.
What's involved
Data will be collected at the beginning of the study and again after 7-8 weeks.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 7-8 weeks after starting the intervention.

Eligibility criteria

Inclusion

Have had a history of ischemic cerebrovascular accident (CVA) within middle cerebral artery (MCA) or anterior cerebral artery (ACA) territory
CVA occurred between six months and six years ago
Moderate to severe UE impairment, FMA-UE score between 15 and 45
Mini-Mental State Examination (MMSE) score \>23 and being able to safely follow three-step commands

Exclusion

Advanced musculoskeletal pathology or recent fractures in the impaired UE
Previous diagnosis of neurological diseases other than stroke
Severe limitation of passive range of motion or spasticity (Modified Ashworth Scale for spasticity at \<3 for UE muscles)
Hemorrhagic CVA or involvement of the posterior cerebral artery
Aphasia sufficient to limit ability to express needs or discomfort verbally or non-verbally
Impaired visual acuity (Severe visual impairments as assessed by the NIH Stroke Scale Visual Field subscale. (score \>0))
Severe hemispatial neglect as assessed by the Line Bisection Test (score \>2)
Severely impaired trunk control (\<4)
Individuals who present with the following on the intended limb:
Open wounds
Fragile skin
Under contact precautions due to an active infection
Participation in another therapy focused on recovery of the impaired arm
Subjects with cardiac pacemakers, electronic pumps or any other implanted medical devices, that are not US-certified
Any Condition that would prevent safe use of the Burt system; such as proprioceptive deficits that impair the ability to process haptic or visual feedback, or unstable shoulder joint as assessed by physical examination
Current pregnancy (self-report)
The concern is strictly towards women who are in the 2nd or 3rd trimester and the eventuality of the arm of the BURT accidentally impacting the woman's belly. The system does have safety features (including a virtual safety wall, to keep the device away from the patient's body) but we are taking this as an extra precaution against any potential harm
