A type of therapy that stimulates specific brain pathways with electromagnetic pulses, combined with physical therapy, significantly reduced overall disability in stroke survivors compared to those who received sham stimulation plus physical therapy, according to preliminary research presented at the American Stroke Association’s International Stroke Conference 2026. The analysis, which examined data from two double-blind, randomized controlled trials, found that electromagnetic network-targeted field (ENTF) therapy helped reestablish normal network organization in the brain after stroke.
Stroke remains a leading cause of long-term disability in the United States, according to the American Heart Association’s Heart Disease and Stroke Statistics 2026 Update. While acute treatments have improved survival rates, many survivors face ongoing motor and cognitive impairments. ENTF therapy targets interconnected neural networks that become electrically disorganized after a stroke. By applying electromagnetic pulse patterns derived from healthy individuals, the therapy aims to facilitate normal network activity.
Lead study author Jeffrey L. Saver, M.D., FAHA, distinguished professor and vice chair for Clinical Research at the David Geffen School of Medicine at UCLA, stated, “These neural networks show electrical disorganization after a stroke. Stimulating these networks with electromagnetic pulse patterns derived from studies in people who have not had a stroke can model and facilitate the reestablishment of normal network organization. This therapy has shown beneficial effects upon organized brain electrical activity and, most importantly, was associated with improved functional recovery for patients after stroke.”
The combined analysis included 124 stroke survivors, with 65 receiving ENTF therapy and 59 receiving a sham treatment. Participants were enrolled about 14 days after stroke and had moderate to severe disability, with an average modified Rankin Scale (mRS) score of 3.9. All participants underwent 40 to 45 sessions over 8 to 12 weeks, with both groups receiving physical therapy during stimulation. ENTF therapy began in the hospital and continued at home using portable kits.
After three months, the percentage of participants who achieved freedom from disability (mRS score 0-1) was 22% higher in the ENTF group (33.8%) compared to the sham group (11.9%). Improvements were also seen across the full range of disability outcomes, with less moderate to severe disability. No serious adverse effects were reported.
American Stroke Association volunteer expert Joseph P. Broderick, M.D., FAHA, professor at the University of Cincinnati’s Gardner Neuroscience Institute, commented, “This study examines two small trials of electromagnetic network-targeted field (ENTF) therapy for stroke patients. The results are preliminary, highlighting the need for larger trials with balanced participant groups to assess the therapy’s effectiveness. ENTF showed no safety issues, and there’s a strong demand for new recovery methods post-stroke.”
The main limitation is that the analysis is based on two small pilot studies, and a single larger trial is needed to confirm these results. Nevertheless, the findings suggest that ENTF therapy, which can be self-administered at home, represents a promising new approach to stroke rehabilitation.
