WE focused on the mechanism of the sacroiliac joint which lies colsest to the center of gravity (C of G) and therefore compared the effect of how mobilization of the sacroiliac joint would affect the center of pressure (COP) and compared it to other stimuli. (objective: 34 healthy adults, 7 male, 27 female. Average 23.4 ± SD 3.5.) WE gave 4 tasks to the same subject. Task 1; Non stimulation (N-S), Task 2; Abdominal stimulation on the sitting (S-sit), Task 3; Abdominal stimulation in the standing (S-stand), Task 4; Sacroiliac joint stumulation on the sidelying (Stim-S). Each test was under open eyed condition for we measured for 30 sec and rested for 30 sec. And we took the average of the three. There are 5 items: length (LNG), envelop (ENV), rectangle (REC), mean of X (MX) and mean of Y (MY).
ACCORDING to the analysis of variance, there were no correlation between 5 items (p >0.05). There were significant difference between 4 tasks (p>0.05). However, we found that the average COP between the difference axis side of MX and MY were, in the case of the right axis side, MX; -1.11, MY; 0.78 and in the case of the left axis side, MX; 5.03, MY; 0.29, showing a tendency for it to move to the side opposite to the stumulated.
IN this study, we were not able to prove that Stim-S affected COP significantly. However, it is very interesting to find that giving it Stim-S, there is a tendency of moving the C of G to the opposite side.

The automatic suspension device (AID-l) suspends patient's body in a standing position by compressed air allowing the patient to walk around the circular handrail without forward propulsion. Reduction of body weight is maintained even automatically and precisely and it prevents completely the patients from falling down.
Its advantages are that (1) patients with open wound or cardiac problems, or patients using prostheses or orthoses are not contraindication, (2) preparation and walking practice are simpler both for patients and staff than therapeutic pool and walking trolley, (3) running cost are lower than therapeutic pool. Its drawbacks are that initial cost is relatively high, only one patient can be trained at a time, and it has no effect of warm water.
We concluded that this device is an indispensable device both for patients with orthopaedic disorders and central nervous system disorders who have difficulties of initiating gait training in the parallel bars.
