Sham Transcranial Laser Therapy
Subjects in this treatment arm will receive IV tPA within 3 hours of stroke symptom onset followed by sham transcranial laser therapy no sooner than 12 hours after tPA and no greater than 24 hours from stroke onset. Transcranial Laser Therapy: Transcranial laser therapy is administered with the NeuroThera® Laser System (NTS) in subjects diagnosed with acute ischemic stroke. A laser system is a medical instrument that concentrates energy light on an area. Laser treatment has been used to deliver intense light energy to aid in the healing of tissues and wounds. The transcranial laser treatment procedure consists of applying the NTS laser to twenty different sites on the skull for two minutes at each site.
