Comparison of gait temporal-spatial parameters between an instrumented mat and inertial movement unit system of older adults in a public park

The purpose of this study was to compare measures of gait temporo-spatial parameters of older adults walking outdoors collected using a GAITRite® instrumented mat and the IMU-based Xsens system. 10 older adults were evaluated during the gait in a public park. Velocity, cadence, step length, swing and stance time measures from the two systems were compared. Differences between the systems’ measures were found only for swing and stance time; the differences were small (< 0.04 s). Therefore, the measures of gait temporo-spatial parameters of older adults walking outside using a GAITRite® and the Xsens system were very similar.
