Electromagnetic Field Stimulation Attenuates Phasic Nociception after Complete Spinal Cord Injury in Rats.
This animal study evaluated whole-body extremely low-frequency EMF stimulation after thoracic complete spinal cord injury in adult male rats. The authors report reduced nociceptive behaviors (hyperalgesia/allodynia) from week 6 onward and restoration of spinal reflexes by week 8. They also report lower glutamate at the injury site and histological findings consistent with reduced lesion volume and glial population in EMF-stimulated rats.
Key points
- The study tested whole-body extremely low-frequency EMF stimulation in a rat model of complete thoracic SCI.
- EMF stimulation was reported to attenuate hyperalgesia and allodynia to thermal, electrical, and chemical stimuli from 6 weeks onwards.
- Restoration of H-reflex and nociceptive flexion reflex was reported at the study endpoint (week 8).
- Glutamate levels at the SCI injury site were reported to be elevated without treatment and reduced with EMF stimulation.
- Histology reportedly showed decreased lesion volume and glial population in EMF-stimulated rats.
- The authors interpret the findings as supporting a beneficial rehabilitation role for EMF stimulation after SCI.
