Facilitation Recovery For Patients With Chronic Stroke: The Q Therapeutic System, Frequency-Tuned Electromagnetic Field Treatment

Evaluate the effectiveness of the Q Therapeutic (BQ 3.0) System for individuals with chronic stroke in improving upper extremity function as determined by change in functional outcome measures after 3-month treatment, including in-clinic and at-home sessions.

Inclusion: FMA-UE score between 22-50 (inclusive) of impaired limb; Difference between Screening and Baseline visit FMA-UE is 3 points or fewer; Age 18 to 80 years of age (inclusive); Stroke due to ischemia or to intracerebral hemorrhage; >6 months to 5 years from index stroke onset; Box \& Block Test score with affected arm is ≥1 block in 60 seconds at Baseline Visit; Able to sit with the investigational System for 40 consecutive minutes; Can follow a 3-step command, such as "take the paper, fold it in half, and return it to me", or a non-verbal equivalent; Willingness to participate in physical exercises during study intervention sessions; Availability of a relative or other caregiver able to assist during study treatment sessions and visits; If female, not pregnant or breastfeeding or planning pregnancy during the study period; Informed consent signed by subject.
