Abstract

Mobility and gait are important indicators of human health. However, measuring them outside of a laboratory setting can be challenging. To measure human physical behaviour in free-living conditions, thigh-worn accelerometers and data-driven algorithms are commonly used. This study explores a deep learning approach that utilises data from a single thigh-worn accelerometer. A temporal convolutional network was trained to predict gait events in healthy adults during various walking conditions. The model demonstrated a high level of detection accuracy (F1 score ≥ 99%) and good time agreement for both gait events, with the 95% limits of agreement being -0.04s and 0.04s. Minor differences in spatiotemporal gait parameters were observed. The results indicate the potential of using a deep learning approach with thigh-worn accelerometry data for future research.
