推拿对脑瘫小儿短潜伏时体感诱发电位的影响

Effect of Massage on short Lateney Somatosensory Evoked Potentials in Children with Cerebral palsy

观察了３０例脑瘫小儿推拿治疗前后的胫神经刺激性短潜伏时体感诱发电位（ＳＳＥＰ）。该电位一般由Ｐ１８、Ｎ２３、Ｐ３１、Ｎ４３Ｐ５４和Ｎ６８６个波组成。治疗前，患儿ＳＳＥＰ表现为波低平、延迟，左右侧波不对称和无反应等，异常率达９３％。经４个多月的推拿治疗，除１例继续变差、３例无变化外，其余患儿的ＳＳＥＰ电压升高，其中患侧波较治疗前增大４４．３４％～１３６．７％（Ｐ＜０．０５）；潜伏时缩短，患侧波Ｐ１８、Ｎ２３和Ｐ３１较治疗前有统计学意义（Ｐ＜０．０５）。治愈率为２５％，总有效率为８５．７１％。结果表明，推拿能改善息几大脑皮层及体感通路的功能。

The short latency somatosensory evoked potentials(SSEP) produced by stimulating the right and left posterior tibianerve(PTN) separately were obtained in 30 children with cerebral pallsy(CP) by electrodes placed on scalp P'3 and P' 4 using referensce on the FPz. Before the massage, the SSEP showed that the amplitudes were lower, the latencies were lengthened, the bilateral SSEP were asymmetric and the responses were absent, etc. The rate of the abnormal SSEP was 90%. About 4 months after the massage, the amplitudes of the SSEP were enhanced in all CP subjects and increased about 44 .34%-136 .70% (P<0.05) in the lesion side, the latencies were shortened, there was significant difference in P18, N23 and P31 componets of lesions side except that the SSEP of 1 Subject took a turn for worse and 3 subjects did not change. The effective rate was 85.71%, the cure rate 25%. The results show that the massage may improve the function of the cerebral cortex and the pathway of somatosensory in children with cerebral palsy.
