A type of therapy that stimulates specific brain pathways with electromagnetic pulses, combined with physical therapy, significantly reduced overall disability in stroke survivors, according to preliminary research presented at the American Stroke Association’s International Stroke Conference 2026. The analysis of two small clinical trials suggests that electromagnetic network-targeted field (ENTF) therapy is safe and effective in reducing disability after stroke.
The study examined data from 124 stroke survivors who were moderately to severely disabled, with an average modified Rankin Scale score of 3.9 at enrollment. Participants were enrolled about 14 days after their stroke and received 40 to 45 sessions of either ENTF therapy or a sham treatment over 8 to 12 weeks, along with physical therapy. ENTF therapy uses electromagnetic pulse patterns derived from healthy brain activity to re-establish normal network organization disrupted by stroke.
After three months, the percentage of participants who achieved freedom from disability (modified Rankin Scale score of 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 in the ENTF group. No serious adverse effects were reported.
“It’s clear that we need more effective rehabilitation therapies to fully improve patient outcomes. This promising potential therapy is unique in that it would be able to be conducted at home by the stroke survivor using a portable kit,” said lead author Jeffrey L. Saver, M.D., FAHA, a distinguished professor at the David Geffen School of Medicine at UCLA.
American Stroke Association volunteer expert Joseph P. Broderick, M.D., FAHA, noted that “the results are preliminary, highlighting the need for larger trials with balanced participant groups to assess the therapy’s effectiveness.” He added that “there’s a strong demand for new recovery methods post-stroke.”
According to the American Heart Association’s 2026 Heart Disease and Stroke Statistics, stroke is the fourth leading cause of death in the U.S. and a leading cause of long-term disability. Motor impairment is the most common complication after stroke. The main limitation of this analysis is that it combines data from two small pilot studies; a larger trial is needed to confirm these findings.
The research will be presented at the American Stroke Association’s International Stroke Conference 2026 in New Orleans, Feb. 4-6, 2026.
