Abstract

Unlabelled:

The Objective of this study was to determine whether stimulation on the brain of SD rats with strong pulsed magnetic field could produce analgesic effect. A stimulator of CADWELL (MES-10) was adopted in the study. The pain index used was the Tail Flick Latency (TFL) of rats. The stimulation parameters were: (1) the intensity percent (20%) and stimulation duration (7 min); (2) the intensity percent (30%) and stimulation duration (3 min). The results showed that the mean Acquired TFL change was 23% (P < 0.01) for the 20% intensity group, and 26% (P < 0.01) for the 30% intensity group.

Conclusion:

These data indicate that the new method for analgesia is effective, and compared with other approaches to stimulation analgesia, this one is non-invasive, easy to operate, and less causative of discomfort.
