a randomized controlled study of the effectiveness of scalp electroacupuncture in improving upper limb motor function in convalescent phase of ischemic stroke.

Conditions: Ischemic Stroke

Summary: this research is primary to compare effectiveness of scalp electroacupuncture and scalp acupuncture on motor function of the upper limb(ul) in convalescence phase of ischemic stroke. the clinical research is a randomized controlled trial (rct),consisting of two arms of scalp electroacupuncture group and sham sclp electroacupuncture group to value difference of upper limb function after 4 weeks. the result indicates that scalp electroacupuncture is more sufficient to alter function. the purpose is to value effectiveness of scalp electroacupuncture on motor function of the upper limb in convalescence phase of ischemic stroke.

upper limb(ul) impairment is common in patients of ischemic stroke and recovery of motor function is important for regaining independence in activities of daily living. researches show that the death toll of people who suffering from stroke more than 200 millions,the annual growth rate of this data reached 8.7%, which ischemic stroke take percentage of 60-70, and who suffered from ul impairment reached about 70%. nowadays, morbidity of ischemic stroke of china is the first of the world. aging is a risk for ischemic stroke，especially over the age of 50 years old, which will increase morbidity rate of ul motor function impairment. ul dysfunction make patients despaired and can not attend social activity normally, decreasing the quality of their lives. attending social activity is very important for people's health, otherwise, people will get a series of diseases, like disability, depressive disorder,etc. this subject is primary to compare effectiveness of scalp electroacupuncture and scalp acupuncture on motor function of the ul in convalescence phase of ischemic stroke. the clinical research is a randomized controlled trial (rct),consisting of two arms of scalp electroacupuncture group and sham sclp electroacupuncture group to value difference of upper limb function after 4 weeks. the result indicates that scalp electroacupuncture is more sufficient to alter function. as a further study, this research contains two parallel arms of scalp electroacupuncture group and sham sclp electroacupuncture group. the purpose is to value effectiveness of scalp electroacupuncture on motor function of the ul in convalescence phase of ischemic stroke, comparing with sham scalp electroacupuncture.

Eligibility criteria:
inclusion criteria: * 2 weeks to 6 months after ischemic stroke experiencing motor difficulties in using the paretic arm, with a fma-ue score in the range of 20 to 40 out of 66 signing of the informed consent form indicating that the subject has understood the aim of the study as well as the procedures involved and that he/she accepts to participate and to comply with the demands and restrictions inherent to the study. exclusion criteria: * any medical condition compromising the safety or the ability to take part to the study (such as insufficient vision or hearing, inability to participate to therapy session, inability to communicate, upper limb condition not linked to stroke, uncontrolled blood pressure, uncontrolled diabetes, co-morbidity) recurrent and moderate to high upper limb pain limiting delivery of rehabilitation dosehistory of more than one epileptic seizures since stroke onset or uncontrolled epileptic seizure mild to severe cognitive impairment (mini mental state exam (mmse) score \ 8/21) moderate to severe hemispatial neglect compromising the ability to take part to the study, as determined by the bells tests (\>6 errors) brain stem stroke had been diagnosed with hemorrhagic stroke. had contraindications to electroacupuncture and mri.
