The Efficacy of a Frequency-tuned Electromagnetic Field Treatment in Facilitating the Recovery of Subacute Ischemic Stroke Patients - a Pivotal Study

About

Brief Summary

This is a multicenter study that will be conducted at up to 20 inpatient rehabilitation facilities (IRFs) in the United States.

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), with treatment initiated in inpatient rehabilitation facilities (IRF) and then continued post-discharge in subjects' homes under periodic remote supervision of a trained site study team member. The study will enroll up to 150 subjects who will be randomly assigned (1:1 allocation ratio) to either active or sham study intervention using BQ 2.0.

Exclusion Criteria:

  • 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 in the 3 months 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, or seizure in the last 5 years.
  • Significant visual disturbances that cannot be corrected (eg, hemianopia, diplopia, severe nystagmus, blindness) 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, heart failure, active psychiatric condition) or life expectancy of less than 6 12 months.
  • 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.
