What happens before the first step? A New Approach to Quantifying Gait Initiation Using a Wearable Sensor.

ABSTRACT:

Background

Walking is a volitional behavior that requires planning and initiation before a step is observed. Following a signal to begin walking, studies of gait initiation in specialized labs have identified three phases that occur during the transition from a standing position via anticipatory postural adjustment (APA) to the first step. Routine instrumented gait testing outside of the laboratory setting focuses on gait execution and does not include gait initiation measures.

Research question

Can a single IMU sensor be used for performing gait initiation evaluations outside the lab?

Methods

We recorded walking in young (N = 41) and older (N = 26) adults using an instrumented gait mat while they were wearing a 3D accelerometer on their lower back. Subjects were inst
