Abstract: Similar to the concept of musical harmony, a person’s walking motions can be constructive, or in phase with the base frequency (consonant), or destructive and out of phase with the base frequency (dissonant). In biomechanics, walking ‘smoothness’ is quantified as the ratio of the amplitude of constructive and destructive acceleration harmonics. In older adults, walking smoothness breaks down into more dissonant states caused by increased ‘out of phase’ motions, and this breakdown occurs faster in individuals at a higher risk of falling. My current work explores practical aspects of the use of this sort of biomechanical variable, such as whether it is impacted by walking on a treadmill, and whether it can be represented by clinical tests of stepping, which would have implications toward improving clinical assessment of mobility function.
