| Outline of Final Research Achievements |
We evaluated the timed up and go test (TUG) using the Laser measurement system in patients with Parkinson's disease (PD), healthy elderly subjects (HO), and healthy young subject (HY) and investigated the characteristics of foot contact positions, leg trajectories and spatiotemporal gait parameters.
As a result, it was confirmed that the minimum distance from the turning point to foot contact position and the turning-phase step length in the PD group are significantly smaller versus those of the HO group, and the two parameters were significantly positively correlated.
We constructed a novel non-contact type 3D motion measurement system using multiple RGB-D sensors that can simultaneously acquire images and depth information, and experimentally verified the validity of the measured gait parameters. The effectiveness of the proposed system was confirmed by applying it to the motion measurement experiment of the elderly with knee osteoarthritis.
