There were very significant differences about the values of MP, MPF and AEMG among the motion muscles, but there was no significant difference about the singals of MF slope, MPF slope and AEMG slope. In patients group there were significant differences about the values of MF, AEMG, AEMG slope of motion limb between paretic side and non-paretic side. There were also significant differences about the values of MPF slope between paretic side of the patients and left side of the health. But there was no significant difference about other parameters in groups or among groups. Compared the activity muscles of four groups, there were significant difference about the values of AEMG and MPF among initiative muscles, antagonistic muscles and co-contraction muscles. There were very significant differences about the values of MF and MPF among co-contraction muscles, but there was no significant difference between initiative muscle and antagonistic muscle.
