RÉSUMÉ
@#Surface transcutaneous electric nerve stimulation(TENS) was applied to treat the spasiticity resulting from spinal cord injury(SCI) in the acupoints of the subjects with SCI in order to oberve thetranscient and long-term effect of the treatment Fand its mechanism will be discussed in this paper. The results show that: 1 )more significant effect in relieving the spasiticiy was got by stimulating in high frequencyfor 30minutes,while less effect in low frequency(2Hz) ; 2)the effect in high frequency was partially ostracized by naloxone; 3)the effect in high frequency lasted for a long time i 4)compared with lumbar and sacralstimulation,the acupoint stimulation lasted for the longest time. This study also gets a hypothesis that highfrequency TENS in acupoints improves dynorphin in CSF to release and significantly relieve the spasiticityby kappa opioid receptor which decreases the excitment of anterior motor neuron.
