Patients with walking disorders are diagnosed by orthopedics and a rehabilitation course in a hospital, but the walking of physically unimpaired persons is not diagnosed. It is considered that if they continue to walk unstably, this may cause lower-back pain or knee pain; this burden also exerts bad influences upon other physical parts. So it is important that we analyze walking stability of physically unimpaired persons as one aspect of preventive medicine.

This study analyzes the walking improvement based on 1/f fluctuations and impulse responses utilizing Auto-Regressive (AR) modeling. Once subjects were aware of the correct posture, the fluctuation of subject's both sides of the hip while walking was improved more rhythmic. The analysis of impulse response utilizing AR modeling provided clear results for the evaluation of improvement to walking stability.

This study analyzes the heart rate and voice response of young students while walking or listening to sounds based on 1/f (f=frequency) fluctuation using FFT spectral analysis. There was more positive 1/f fluctuation in heart rate response in normal walking or while listening to comfortable sounds than under stressful conditions, whereas the response was negatively influenced by walking with a heavy bag or while listening to noisy sounds. This study provides a useful method for preventive medicine, physical fitness, and a means for young subjects to maintain a state of well-being.

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.

The walking stability becomes less stable under the influence of a problematic posture or back. This problem was analyzed on the basis of two new approaches. The first approach is a newly developed measurement system, consisting of two accelerometers for walking analysis.
