1301por Gregory, Jennifer S, Stewart, Alison, Undrill, Peter E, Reid, David M, Aspden, Richard M“…PCA analysis was found to perform better than fractal analysis (P = 0.019). CONCLUSIONS: Both PCA and fractal analysis of the FFT data could discriminate successfully between the fracture and control groups, although PCA was significantly stronger than fractal dimension. …”

1306por Hove, Michael J., Suzuki, Kazuki, Uchitomi, Hirotaka, Orimo, Satoshi, Miyake, Yoshihiro“…Parkinsonian gait consists of random, disconnected stride times—rather than the 1/f structure observed in healthy gait—and this randomness of stride times (low fractal scaling) predicts falling. Walking with fixed-tempo Rhythmic Auditory Stimulation (RAS) can improve many aspects of gait timing; however, it lowers fractal scaling (away from healthy 1/f structure) and requires attention. …”
