three groups of commonly acupunctured points were compared in terms of the impact on apoplexy and therapeutic mechanism by using single photon emission CT(SPECT). Regional cerebral blood flow and cerebral function of 70 apoplectic patients were examined with SPECT before and after electro-acupuncture. Results suggested electro-acupuncture can markedly improve regional cerebral blood flow and cerebral function in apoplectic patients, and all acupoint groups effectively activated relative cerebral functions. Acupuncture is proved to be effective to treat apoplexy, which laid a foundation for establishment of therapeutic standard and guidelines for clinical practice.
