Entropy analysis of tri-axial leg acceleration signal waveforms for measurement of decrease of physiological variability in human gait.

Journal of orthopaedic research : official publication of the Orthopaedic Research Society - 1 Jun 2012

Tochigi Yuki, Segal Neil A, Vaseenon Tanawat, Brown Thomas D

Abstract excerpt

Disease-related and senescent decrease of physiological variability in biological time-series outputs (e.g., heart rate) has drawn increasing attention as a potential new type of biomarker. In this paradigm, measurement of variability in periodic motion may enable quantitative evaluation of functional limitation in people with musculoskeletal disorders. A novel technique to measure variability of leg motion...
