This study was compared the variation system of body posture condition for stability by the posture. We used a model of bio parameter on the basis of the move state in the standing posture. We compared the sway movement derived from average of the physical sensing condition. Vision condition of variation average (Vi-${sigma}_{AVG-AVG}$) was verified slightly greater at $13.746{pm}4.05$ unit. Vestibular condition of variation average (Ve-${sigma}_{AVG-AVG}$) was verified slightly larger at $7.829{pm}1.071$ unit. Somatosensory condition of variation average (So-${sigma}_{AVG-AVG}$) was verified slightly smaller at $2.592{pm}0.538$ unit. CNS condition of variation average (C-${sigma}_{AVG-AVG}$) was verified slightly larger at $0.46{pm}0.105$ unit. The valuation system will be to deduce the model of body management with falling and stroke and all that sort of things. There will be to infer a data algorithm and the evaluation of processing system.
