The treatment effet was compared with the control group disposed by binding, seizing and nipping the mouse hair at the jiaji points(ex-b2) at the same time. In this study, we proceeded Tail Suspension Test, Turn-club Test to investigated the onset of the disease，survival time of the mice and motor function during the process of the disease, 2 times/week from the age of d60 to the end event occurrence. All the data&nbsp; obtained&nbsp; through&nbsp; aforementioned&nbsp; procedure&nbsp; was&nbsp; analyzed&nbsp; by&nbsp; the&nbsp; using&nbsp; of&nbsp; SPSS&nbsp; 17.0,&nbsp; gaussian distribution was test first for every group.Data which is in accordance with normal distribution proceeded with independent-samples t test subsequently, and data that is not conform to the normal distribution were going on with rank sum test. Results of the analysis presented as mean value±standard deviation；KaplanMeier&nbsp; Survival&nbsp; analysis&nbsp; was&nbsp; proceeded&nbsp; to&nbsp; analyze&nbsp; the&nbsp; survival&nbsp; datas.&nbsp; We&nbsp; setted&nbsp; p＜0.05&nbsp; stands&nbsp; for&nbsp; the&nbsp;</p><p style="text-align: justify;">difference has significant meaning. Results: 1. Analysis of onset and survival time: EA group shows the delay of&nbsp; the&nbsp; onset&nbsp; of&nbsp; the&nbsp; disease&nbsp; for&nbsp; 9&nbsp; days&nbsp; compared&nbsp; with&nbsp; the&nbsp; control&nbsp; group,&nbsp; the&nbsp; difference&nbsp; has&nbsp; significant meaning(p＜&nbsp; 0.01)， and the EA group shows a prolong of the survival time of ALS mice for 7 days compared with&nbsp; the&nbsp; control&nbsp; group,&nbsp; the&nbsp; difference&nbsp; has&nbsp; significant&nbsp; meaning(p＜0.01).&nbsp; &nbsp; 2.&nbsp; Analysis&nbsp; of&nbsp; Weight:Data shows that mice weight of EA group was higher than that of the control group from the age of week21, difference has significant meaning(p＜0.05).&nbsp; &nbsp; 3. Analysis of Turn-club Test:residence time has declined since the mice age of week16 in control group, and since the mice age of week17 in EA group.residence time of EA group is significantly longer than that of the control group from the age of week16,difference has&nbsp; significant meaning(p＜0.05). <strong>Conclusion</strong>: 1)Electroacupuncture&nbsp; at&nbsp; jiaji&nbsp; points（ex-b2）delays&nbsp; the onset&nbsp; of&nbsp; the&nbsp; disease&nbsp; and&nbsp; prolong&nbsp; the&nbsp; survival&nbsp; time&nbsp; of&nbsp; the&nbsp; ALS&nbsp; SOD1^G93Atransgenic&nbsp; mice. 2)Electroacupuncture at jiaji points（ex-b2） improve motor function of the ALS SOD1^G93A transgenic mice.&nbsp;</p><p><strong>Key words</strong>: Electroacupuncture, Jiaji points(ex-b2), Amyotrophic lateral sclerosis, Survival time&nbsp;</p><p><br/></p>
