Assistive locomotion strategies for active lower limb devices

Joana Figueiredo, Juan C. Moreno, Cristina P. Santos
2017 2017 IEEE 5th Portuguese Meeting on Bioengineering (ENBENG)  
The solution validation in different locomotion conditions (assisted walking by WR, walking of humanoid robot and walking of healthy subject) shows up that the proposed solution led to a robust and general  ...  The first locomotion strategy proposed and validated addresses online detection of events and gait phases uniquely through information from embedded sensors.  ...  general solution that detects events and gait phases, and proceeds to locomotion recognition in different contexts of locomotion for healthy, people with motor impairments and biped robots.  ...

Effect on gait using various prosthetic ankle-foot devices

Roy W. Wirta, Randy Mason, Kevin Calvo, Frank L. Golbranson
1991 Journal of rehabilitation research and development  
Ratings were related to age, body weight, length of residual limb, and ratio of stride frequency to stride length.  ...  Five different comnionly prescribedD ankle-foot devices for below-knee prostheses were tested for effects on gait: SACH, SAFE, SEATTLE, SINGLE AXIS, and MULTIPLE AXIS.  ...  By comparison, the harmonic ratios of healthy individuals are in excess of 3.0. Harmonic ratios did not correlate with angular accelerations of the prosthesis.  ...
