Brief Summary
This is a multicenter study that will be conducted at approximately 20 centers. BQ 2.0 is a wearable medical device that produces and delivers non-invasive, extremely-low-intensity and low-frequency, frequency-tuned electromagnetic fields in order to stimulate neuronal networks with the aim of reducing disability and promoting neurorecovery. In this study, BQ 2.0 is intended to reduce disability in adult patients with subacute ischemic stroke, with a moderate to severe disability which includes an upper extremity motor impairment. BQ 2.0 will be used for 9 weeks in conjunction with physical and occupational therapy (PT/OT) and periodic supervision (either remote or in person) of a trained site study team member. Treatments may be administered in multiple settings (e.g. acute care hospital (ACH) or inpatient rehabilitation facilities (IRF), Skilled Nursing Facility (SNF), home or other outpatient setup). The study will enroll up to 150 adult subjects who will be randomly assigned (1:1 allocation ratio) to either active or sham study intervention using BQ 2.0.

Study Arms (2)
BQ 2.0 sham stimulation group
SHAM COMPARATOR45 sessions over a period of 9 weeks (5 treatments per week) of sham study intervention with BQ 2.0 including a standardized, pre-defined and evidence-based physical and occupational therapy regimen concurrent with the study intervention.
BQ 2.0 active stimulation group
ACTIVE COMPARATOR45 sessions over a period of 9 weeks (5 treatments per week) of active study intervention with BQ 2.0 including a standardized, pre-defined and evidence-based physical and occupational therapy regimen concurrent with the study intervention.
Interventions
frequency and intensity parameters will be set to zero so that no stimulation is delivered
Eligibility Criteria

- Able to sit with the investigational device for 40 consecutive minutes.
- Can follow a 3-step command, such as "take the paper, fold it in half, and return it to me".
- Willingness to participate in occupational/physical therapy activities during study intervention sessions.
- Availability of a relative or other caregiver able to assist during PT/OT treatment delivered via video call sessions during the study.
- If female, not pregnant (as confirmed by a urine or a blood test, or as determined by an official medical document) or breastfeeding and with no ability to become pregnant or on an acceptable method of contraception during the study
- Informed consent signed by subject (if competent) or legally authorized representative.
You may not qualify if:
- Severe neglect impairment (NIHSS item 11 score = 2) or neglect that is severe enough to interfere with reasonable performance of study procedures. assessments or treatments.
- Implanted active electronic or passive MR-incompatible devices.
- Previous ischemic or hemorrhagic stroke within the 2 weeks before the index stroke.
- Pre-existing neurological condition (eg, Alzheimer's disease, Parkinson's disease, multiple sclerosis, traumatic brain injury, spinal cord injury) or physical limitation that would interfere significantly with the subject's participation in the study and/or confound neurological or functional evaluation.
- Active epilepsy or currently taking anti-epileptic medication (indicated for the treatment of a seizure disorder), or seizure in the last 5 years.
- Significant visual disturbances that cannot be corrected and that would interfere significantly with the subject's participation in the study and/or confound neurological or functional evaluation.
- Unstable serious illness/condition (eg, active cancer, severe heart failure, active psychiatric condition) or life expectancy of less than 6 12 months.
- A known severe allergic reaction to acrylic-based adhesives.
- Ongoing alcohol abuse and/or illicit drug use.
- Participation in another trial that would conflict with the current study or clinical endpoint interference may occur.
- Employee of the Sponsor.
- Prisoner.

- Masking Details
- This is a double-blind study, subjects and Investigators will be blinded to the device setting (Active/Sham). The study site team members receiving, storing, dispensing, preparing, and administering the study interventions will be blinded. Subjects' caregivers will also be blinded. There are no differences in the active and sham device appearance. Due to the non-invasive nature of the treatment, as well as the physical characteristic of the EMF, there is no noticeable difference between sessions conducted using an active or a sham device, facilitating full blinding of both subjects and Investigators. An independent unblinded statistician (not the study statistician) will perform the assessments described. Only the unblinded statistician and members of the DSMB will be exposed to the interim report.
