We have treated 172 cases of N. S. diseases with PEC-88A Type of the Programmed Electroacupuncture Apparatus with shows of frequency and voltage of electro-pulse. Of 172 cases

47 cases were cured (27.3％)

77 markedly effective (44.8%)

44 improved (25. 6%)

4 failed (2. 3%).The total effective rate was 97. 7%. The observation showed that different stimulating strength was needed to different disease through observation of the stimulating strength of electroacupuncture. The strongest was for the sequela of poliomyelitis. The next was for the sequela of apoplexy. The lightest was for sciatica. and during treatment the stimulating strength to disorder side is larger than one of normal side. By the way

the stimulating strength of electroacupuncture was reduced step by step while thedisease becomebetter little by little.) The result of clinical observation displaed that the stimulating strength was determined according to the part of injured N. S and patient's sensitivity to the stimulating strength of electroacupuncture when useing electroacupuncture.
