Objectives : The aim of this systematic review was to assess the efficacy of acupuncture and its relevant modality on post-stroke muscle spasticity Methods : We included 7 randomized controlled trials(RCTs) and 1 crossover study on acupuncture on the post-stroke muscle spasticity. Articles searches were performed in various databases in October 2009. Eight studies from 38 articles met the inclusion criteria and were used to assess the quality of clinical trials by means of Jadad scale, STRICTA, CONSORT statement and cochrane-handbook for systematic reviews of interventions. Results : Electrical stimulation such as electroacupuncture and TENS on acupoints was used in five studies. Repeatition of electroacupuncture showed significant decrease of the post-stroke muscle spasticity and persistence of the effect. Only three studies were assessed high quality as the methodological assessment tool(Jadad scale) and none of the studies matched STRICTA recommendations. Conclusions : This systematic review shows that there is beneficial effects of electroacupuncture on the post-stroke muscle spasticity. Further study of large population with high methodological quality will be needed.
