Chronic magnetic field exposure appeared to restore food intake, water intake, and body weight in spinal-cord-injured rats.

Plain English Summary

Summary written for general audiences

Researchers studied the effect of magnetic field exposure on food intake, water intake, and body weight in rats with complete spinal cord injury. Exposure ran at 50 Hz and 17.9 T for 2 hours per day over 8 weeks in rats with complete spinal cord transection at the T13 level. The results suggest a significant beneficial effect of chronic exposure to magnetic field of paraplegic rats.

Why This Matters

Food intake, water intake, and body weight were decreased in the spinal cord injured rats before magnetic field exposure. The study used a 50 Hz magnetic field at 17.9 T, applied for 2 hours per day across 8 weeks.
