Time-Varying Ankle Mechanical Impedance During Human Locomotion
Hyunglae Lee,Neville Hogan +1 more
TL;DR: It is found that viscosity and stiffness of the ankle significantly decreased at the end of the stance phase before toe-off, remained relatively constant across the swing phase, and increased around heel-strike, important evidence of “pretuning” by the central nervous system.
Journal ArticleDOI
Summary of Human Ankle Mechanical Impedance During Walking
TL;DR: The purpose of this short communication is to unify the results of the first two studies measuring ankle mechanical impedance in the sagittal plane during walking, where each study investigated differing regions of the gait cycle.
Journal ArticleDOI
Multivariable Static Ankle Mechanical Impedance With Active Muscles
TL;DR: This characterization of young healthy subjects' ankle mechanical impedance with active muscles will serve as a baseline to investigate pathophysiological ankle behaviors of biomechanically and/or neurologically impaired patients.
Journal ArticleDOI
Multivariable static ankle mechanical impedance with relaxed muscles.
TL;DR: A novel procedure to characterize static multivariable ankle mechanical impedance using a wearable therapeutic robot and a vector field, sufficiently sensitive to detect a subtle but statistically significant deviation from spring-like behavior if subjects were not fully relaxed, may provide new insight about the function of the ankle.
Journal ArticleDOI
Multivariable Dynamic Ankle Mechanical Impedance With Relaxed Muscles
TL;DR: A quantitative characterization of multivariable ankle mechanical impedance of young healthy subjects when their muscles were relaxed is presented, to serve as a baseline to compare with pathophysiological ankle properties of biomechanically and/or neurologically impaired patients.
