Fig. 1From: Walking orientation randomness metric (WORM) score: pilot study of a novel gait parameter to assess walking stability and discriminate fallers from non-fallers using wearable sensorsDiagrammatic model of human body during walking. WORM score calculation reflects truncal motion as a measure of walking (in)stability. WORMdist is calculated as the distance travelled in the transverse plane travel by p, (the length of the blue outline) measuring truncal motion during the walking bout.
