摘要： A method and system for analysing gait patterns of a subject by measuring head acceleration in vertical direction. The system comprises an accelerometer mounted on the head of the subject. The analysis includes calculating a signature from the acceleration data, using a Fourier transform, including energy of the first harmonics and comparing the signature with the baseline signature. Baseline signature is a representative of previously stored signatures. The comparison is done in order to monitor changes in the gait signatures over time. The entropy of the signatures may be used to perform the comparison. A self organised map is used to classify the measured gait signals.
