Rats were divided into 2 groups (n=10 each): 1) rats with hemisection of thoracic spinal cord and exposure to the magnetic field and 2) rats with hemisection of thoracic spinal cord and sham exposure.
|Setup||six rats placed in a cage in the center of a Helmholtz coil system; coil system consisting of 2 outer and 2 inner coils (diameter of 1000 mm) with 18 and 8 turns of wire; coils connected in series|
|Sham exposure||A sham exposure was conducted.|
|magnetic flux density||17.96 µT||-||measured||-||-|
The food intake was significantly higher in rats exposed to the magnetic field in weeks 5 and 6 compared to sham exposed rats.
The motorial functions were significantly improved in the exposure group from week 2 on compared to the sham exposure group.
Nociception was significantly improved in the exposure group compared to the sham exposure group from week 3 on.
The urinary bladder control was significantly better in the exposure group from days 4 to 6 compared to the sham exposure group, with a complete restoration of function from day 5 on. On day 7, the urinary bladder function was restored completely in both groups.
The H-reflex amplitude was significantly reduced in the exposure group compared to the sham exposure group.
The authors conclude that chronic exposure of rats with hemisection of the thoracic spinal cord might improve the restoration of sensory-motor functions.
