| Outline of Final Research Achievements |
The present project aimed to establish the rationale of a novel simplified gait analysis method, namely the Entropy of Leg-Linkage Inertial Signals (ELLIS) method. Specifically, work was proposed to test its capabilities in detecting decrease of gait flexibility associated with increased stress, and in addressing peri-operative longitudinal changes of gait quality in clinical cases of knee osteoarthritis. The experimental data have indicated that physiological variability in leg kinematics increases with increased stress in gait, supporting the basic concept of the ELLIS method. The data also have suggested technical challenges in standardization about gait velocity, which is important for eliminating effects from body size variability and general physical status.
