Spectral analysis of walking with shoes and without shoes.

This study analyzes the walking balance of young students based on 1/f fluctuations using auto-regressive (AR) modeling. There was more good walking balance than bad, influenced positively or negatively by the students' shoes. After the subjects understood their own walking condition, based on 1/f fluctuation, and had received suitable rehabilitation and shoes, their walking balance became better. This study provides a useful new method of medical evaluation in rehabilitation and physical fitness, and a means for subjects to maintain a state of well being.
