From: Differences in gait and trunk movement between patients after ankle fracture and healthy subjects
The typical plot of lower trunk tri-axial acceleration signals from both ankle fracture patients and healthy participants during 5 m of self-selected comfortable walking samples at 100 Hz. The two black bars represent the moment of infrared-defined gait initiation and termination. The black arrow indicates the start of the measurement. The white arrow indicates the end of the measurement. The asterisks around peak AP acceleration values indicates initial foot contact of each integer step. AP anterior–posterior, ML medio-lateral, VT vertical
