Validity of DynaPort GaitMonitor for assessment of spatiotemporal parameters in amputee gait

Han Houdijk, PhD, et al.

In this study, we tested the suitability of the DynaPort GaitMonitor for evaluating amputee gait. The GaitMonitor uses a small measuring device (accelerometer) placed at the back of the pelvis to measure average step time, step length, and walking speed. We found that the GaitMonitor can measure these gait characteristics during a controlled unidirectional walking task with sufficient accuracy. However, separate step time measurements of the intact and prosthetic leg were systematically over- and underestimated. Therefore, gait symmetry could not be measured adequately. We conclude that the DynaPort GaitMonitor can be used to quantitatively evaluate amputee gait during rehabilitation and prosthetic prescription.
