In the case of patients having lower back pain, it is known that by using shoe insole therapy, stability of walking is increased and lower back pain is lessened. In this study, Synchronized System of Accelerometers was used. The time series data of accelerator in the two directions (X, Y) on each pelvis and knees were measured while the subjects were walking. Analyses on the response of step signals add to the system shows that in the case of the subjects wearing shoe insole, walking stability is increased more than without insoles. And the relative power contribution shows dynamic time-spatial relationship of both the knee and pelvis.
