The Efficacy of a Frequency-tuned Electromagnetic Field Treatment in Facilitating the Recovery of Subacute Ischemic Stroke Patients - a Pivotal Study (THE EMAGINE STUDY)
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.
