Frequency-tuned electromagnetic field therapy improves post-stroke motor function: A pilot randomized controlled trial.
This pilot randomized, sham-controlled, double-blind trial evaluated extremely low frequency, low-intensity ENTF electromagnetic field therapy in subacute ischemic stroke patients with impaired upper extremity function. The per-protocol results reported greater improvements in motor function and disability outcomes in the active ENTF group compared with sham. No treatment-related adverse events were reported, and the authors call for larger multicenter confirmation.
Key points
- The study used a randomized, sham-controlled, double-blind design in subacute ischemic stroke patients.
- Exposure was extremely low frequency, low-intensity EMF stimulation (1β100 Hz, <1 G) delivered 40 minutes per session for 8 weeks.
- Primary outcome was change in FMA-UE from baseline to 8 weeks, with additional upper extremity and global disability measures assessed.
- Per-protocol results reported greater early improvement (week 4) in FMA-UE with ENTF versus sham.
- Favorable week 8 differences were also reported for Action Research Arm Test (Pinch), Box and Blocks Test, and modified Rankin Scale.
- No treatment-related adverse events were reported in the abstract.
- The authors describe the findings as preliminary and recommend confirmation in larger multicenter studies.
