Transient Effect of the Different Order of Interference between Acnpuncture and Exercise Therapy on the Somatosensory Evoked Potential in the Patient of Hemiplegia after Stroke

Purpose:To investigate transient change on the hemisphere brain somatosensory evoked potential (SEP) in the patients of stroke under the different order of interference: exercise after acupuncture or acupuncture after exercise.Methods:62 cases of hemiplegia after stroke were divided into group A which was ordered to raise handclasp of Bobath after puncturing Quchi(LI 11)and Hegu(LI 4) on the affected side (n=31)and group B which was pun- ctured Quchi(LI 11) and Hegu(LI 4)on the affected side after raising handclasp of Bobath (n=31). Prior to and after every interference, the change of SEP on the affected side was recorded.Results:(1) There was a significant difference of SEP in the patients prior to and after treatment of simple acupuncture or exercise therapy(P<0. 01), but there was no significant difference between the two therapies(P>0. 05).(2)There was a significant difference of SEP in the two groups(P<0.01)and Statistic difference existed in the two groups of different order of interference.Conclusion:Both acupuncture and exercise therapies could improved SEP of hemiplegia
