“…Owing to the general nature of this measure, it can also be used to assess recovery of the gait pattern after a perturbation. To date, however, the extrapolated centre of mass has only been used in this manner in a few studies [161,165,166].…”

Falling poses a major threat to the steadily growing population of the elderly in modern-day society. A major challenge in the prevention of falls is the identification of individuals who are at risk of falling owing to an unstable gait. At present, several methods are available for estimating gait stability, each with its own advantages and disadvantages. In this paper, we review the currently available measures: the maximum Lyapunov exponent (l S and l L ), the maximum Floquet multiplier, variability measures, long-range correlations, extrapolated centre of mass, stabilizing and destabilizing forces, foot placement estimator, gait sensitivity norm and maximum allowableperturbation. We explain what these measures represent and how they are calculated, and we assess their validity, divided up into construct validity, predictive validity in simple models, convergent validity in experimental studies, and predictive validity in observational studies. We conclude that (i) the validity of variability measures and l S is best supported across all levels, (ii) the maximum Floquet multiplier and l L have good construct validity, but negative predictive validity in models, negative convergent validity and (for l L ) negative predictive validity in observational studies, (iii) long-range correlations lack construct validity and predictive validity in models and have negative convergent validity, and (iv) measures derived from perturbation experiments have good construct validity, but data are lacking on convergent validity in experimental studies and predictive validity in observational studies. In closing, directions for future research on dynamic gait stability are discussed.

“…The concept of the extrapolated CM has also been used to compare overground with treadmill walking, showing that the lateral margin of stability does not change significantly between the two situations, although step width was significantly larger on the treadmill (Rosenblatt and Grabiner, 2010). While the objectives of the above studies have varied, most studies only investigated a few trials and examined one specific body side (Bierbaum et al, 2010Rosenblatt and Grabiner, 2010;Hoehne et al, 2011) without knowledge about reproducibility and symmetry of the examined parameters. The comparison between subject groups or between conditions may only be valid in cases where the differences between groups or conditions are higher than the normal variability within a group.…”
